Introduction

One constant in the study of mass communication has been the never ending battle between the limited and powerful effects paradigms. Like the eternal debate about Bud Light -- tastes great vs. less filling -- communication scholars have been debating the relative power of the mass media to shape opinions and social structure for some 50 years.

The limited effects model, often cited as the dominant paradigm in the field (Katz, 1987), is identified with the Columbia election studies (Lazarsfeld et al., 1944; Berelson et al., 1954) and Hovland's research into the effectiveness of Army training films (1965). These studies generally asked the question "what do the media make people think/do?" In the case of the election studies this meant voting behavior, and with Hovland's research whether films could change soldiers morale and willingness to fight. Both studies found that the media did provide information, but that it had little effect in changing people's opinions or behavior. These limited effects findings were summarized by Klapper (1960) who concluded that:

Mass communication ordinarily does not serve as a necessary and sufficient cause of audience effects, but rather functions among and through a nexus of mediating factors and influences. These mediating factors are such that they typically render mass communication a contributory agent, but not the sole cause, in a process of reinforcing existing conditions. (p. 8).

Klapper's summation, and the limited effects paradigm in general, has been blamed for driving sociologists away from the study of media resulting in a "famine" of communication research during the 1960's (Gans, 1972).

Unsatisfied with the limited effects paradigm, beginning in the 1970's a number of scholars came forward to reconceptualize effect, and call for new powerful media effects. Katz (1987) summarizes these new theories as institutional, critical, and technological. Institutional theories argue that the media don't tell us "what to think" so much as "what to think about." Chief among institutional theories is agenda setting which claims that the media set an agenda which the public follows (McCombs and Shaw, 1972). Critical theories argue that limited effects findings are actually an attribute of a larger hegemonic social system which encourages no change at all. To critical theorists, the media serve as legitimating tools of a capitalist status-quo, keeping the public blissfully unaware of their subordination (Gitlin, 1978; Hall, 1973; Horkheimer and Adorno, 1973). Finally, technological theories argue that the very nature of mass media help to determine social structure. Examples of this theory include Eisenstein's argument that the printing press led to the Protestant Reformation, and Carey's finding that the telegraphy helped create a nation wide marketplace for American business. The classic statement of this paradigm is Marshall McCluhan's oft quoted aphorism, "the medium is the message (1964)."

A very interesting subset of traditional media effects research is the study of "pornography effects." While the limited effects - powerful effects debate has largely been confined to the halls of academia (with the notable exception of media violence) the pornography debate is infinitely public and political. Indeed, the pornography issue has served as a lightning rod for attention and polemics over the past 30 or so years. The debate has brought out religious conservatives, political conservatives, feminists, anti-porn feminists, anti-censorship feminists, civil libertarians, free speech advocates, and a host of other interested groups. All have engaged in an intense and ongoing debate about the potential harms of pornography, and whether or not such content should be censored.

Interest in pornography effects began during the 1960's as the U.S. and a number of other industrialized nations began to see a sharp rise in the quantity and availability of pornography and other forms of sexually explicit entertainment. This rise occurred concurrently with what is often referred to as the "sexual revolution (Goldstein and Kant, 1973; McNair, 1996)." The rise in pornography led to a number of studies investigating pornography's role in sexual arousal, and sexually deviant behavior. In particular, early research asked if exposure to pornography was related to sex crimes, and oddly enough, the truancy of minors. Early concerns over pornography's effects culminated in the 1968 appointment of the United States President's Commission on Obscenity and Pornography. The Commission was charged with understanding "the effect of obscenity and pornography upon the public and particularly minors, and its relationship to crime and other antisocial behaviors (U.S. Commission, 1970: 1)." After two years of study and testimony, the Commission concluded that pornography had no discernibly harmful effects on society:

In sum, empirical research designed to clarify the question has found no evidence to date that exposure to explicit sexual materials plays a significant role in the causation of delinquent or criminal behavior among youths or adults. The Commission cannot conclude that exposure to erotic materials is a factor in the causation of sex crime or sex delinquency.

In fact, the Commission made the argument that pornography likely had a cathartic effect for citizens, pointing out that the majority of sex offenders surveyed had come from sexually repressive homes where pornography was not available. Similar conclusions were reached nine years later by the Williams Committee in England (Home Office, 1979). Due to these "no effect" results, the Johnson and Williams Commissions are largely analogous to the Columbia school of limited effects. And just like the Columbia school, the "limited porn effects" findings came under enormous criticism.

Politicians and feminist scholars alike simply could not believe the limited effects conclusions of the two commissions. Their objections, along with a general agreement among scholars that pornography was becoming more and more violent, led to a reassessment of the limited effects of pornography. In the U.S. the relationship between violent pornography and attitudes and crimes towards women was taken up by a group of experimentalists (Donnerstein, Malamuth, Linz, Zillmann, Bryant, etc.) who attempted to find new powerful effects. Their "powerful porn effects" findings (although this will be shown later to be an exaggeration) culminated in the 1985, Attorney General's Commission on Pornography, otherwise known as the Meese Commission. The Meese Commission concluded that "the research shows a causal relationship between exposure to sexually violent material and aggressive behavior toward women" and that such material "leads to greater acceptance of the 'rape myth' it its broader sense -- that women enjoy being coerced into sexual activity, that they enjoy being physically hurt in sexual context (1986, p. 327)." The Commission additionally concluded that even some forms of "non-violent" pornography resulted in anti-social behavior (Linz, 1989). Despite a great body of criticism for the Meese Commission, it is still identified by many as the statement of "powerful pornography effects."

Concurrent with experimentalists attempts to find powerful effects for pornography, anti porn feminist scholars (Dworkin and MacKinnon) developed their own answer to the limited effects of the Johnson and Williams Committee findings. They developed what is often referred to as the "ideological" view of pornography's effects, which argues that pornography is the main weapon by which a patriarchal society maintains dominance over women. As such, the ideological view of pornography can operate without causal findings of harm, although anti porn feminists do use experimental evidence to support their larger theory. This ideological/hegemonic view of the effects of pornography would seem very similar to the critical school in traditional mass communication research.

This brief overview of the history and development of the pornography effects literature shows just how similar it is to traditional conceptualizations of the mass media effects debate. The pornography issue started out with findings of limited effects (similar to the Columbia school), these findings were questioned, and effects were retested and reconceptualized. This resulted in the emergence of two powerful effects traditions, one experimental (similar to the cognitive revolution) and one ideological (similar to the critical school). Still other off shoots of pornography effects research has investigate how people use pornography (similar to uses and gratifications), and how groups receive and manipulate pornographic texts (reception theory).

The goal of this paper is to outline a number of powerful, limited, and alternative conceptualizations of pornography's effects. Powerful effects of pornography include arousal, desensitization, increased aggression, attitude change towards women, catharsis, and male hegemony. Limited effects generally encompass research which questions claimed powerful effects. Finally, alternative conceptions such as uses and gratification and reception analyses attempt to go beyond the effects "muck" and find out what people actually do, both socially and politically, with pornography.


Defining Pornography and Conceptualizing Effect

On the surface, the study of the effects of pornography would seem relatively straight forward. After all, the word pornography is widely held as a pejorative term that must have negative effects on society. Despite this generally held belief (just like the general belief in powerful media effects), the term pornography and the conceptualization of its supposed effects has sparked intense debate. This has taken the form of a definitional debate about the term pornography, and a conceptual debate about different types of pornography effect.

Porn, Erotica, Obscenity?

The debate about what constitutes pornography has occurred among all levels and institutions of society for years. For example, writing in 1936, D. H. Lawrence commented "what is pornography to one man is the laughter of genius to another (1936, p. 11)." Others have casually observed that "one person's erotica is another person's pornography (cited in Russell, 1993)." Within a legal context, Justice Stewart of the Supreme Court provided the now famous statement "I know it when I see it (Jacobellis v. Ohio, 1964)." These comments point to the difficulty in defining something as subjective as what arouses individuals sexually into specific categories.

The first, and easiest definitional issue is that between obscenity and pornography. The term obscenity, whose Latin root, obscensus, means "filthy" or "repulsive", was originally used by 18th century English judges to describe and censor sexually suggestive poems and stories. In the U.S. the term has taken on a very specific legal meaning, such that any content deemed obscene by the Miller test (Miller v. California, 1973) is considered illegal. This is in contrast to pornography -- whose Greek root pornographos, which means "writing about harlots" -- which is given full protection under the U.S. Constitution (Tedford, 1993). Thus, despite pornography's pejorative connotation, it is entirely legal and separate from the legalistic "obscenity."

Attempting to address the issue of "bad" pornography vs. "good" erotica, is Gloria Steinem. She argues that the word origin of erotica is "eros" which means passionate love or yearning for another person. Thus, erotica is defined as "a mutually pleasurable, sexual expression between people who have enough power to be their by positive choice." This is in contrast to pornography, whose root is about prostitution, and therefore connotative of the objectification and dominance of women. This leads Steinem to conclude that pornography's message "is violence, dominance, and conquest. It is sex being used to reinforce some inequality, or to create one, or to tell us that pain and humiliation are really the same as pleasure (1978)."

Steinem's feminist definitions of erotica and pornography begin to hint at power, objectification, and subordination as key elements. These ideas are taken up wholeheartedly by several anti porn feminists who have formulated an ideological definition of pornography. For example, Catherine Mackinnon (1983) defines pornography as the very embodiment of dominance:

Pornography is the celebration, the promotion, the authorization and the legitimization of rape, sexual harassment, battery and the abuse of children. All for the purpose of the sexual pleasure of men. Simply put pornography eroticizes dominance and submission, of which rape, battery, sexual harassment, and the sexual and physical abuse of children are also forms of practice. It is affirmatively employing the enforcement of others' powerlessness.

In a similar fashion, Diana Russell (1993) defines pornography as "material that combines sex and/or the exposure of genitals with abuse or degradation in a manner that appears to endorse, condone, or encourage such behavior (p. 2)." This is in contrast to erotica, which Russell sees as sexually suggestive but "free of sexism, racism, and homophobia, and respectful of all human beings and animals portrayed (p. 3)." Taken together, these ideological definitions see porn as more than a "something" but rather as quite literally an action.

Stepping as far away as possible from the feminist politicization of pornography, most experimentalists have come to define the term as meaning "those explicit sexual depictions whose purpose or effect is to bring about sexual arousal in the ordinary viewer or reader (Williams, 1979: 196; Malamuth and Donnerstein, 1982: 105; Garry, 1983: 62)."

This plethora of definitions for pornography, erotica, and obscenity resulted in a meaning gridlock that is reflected in the Meese Commission's rather humorous attempts to deal with the terms. First the Commission noted that pornography had an "undoubtedly pejorative" connotation, and would therefore attempt "to minimize the use of the word" in its report. The Commission then concluded that erotica had a similarly negative connotation and it would also minimize the use of this term. Finally, it concluded that obscenity was a purely legal term (Hawkins and Zimring, 1988: pp. 23-24). Thus, the Meese Commission on Pornography couldn't come up with a usable word to describe the main subject of its own inquiry and report!

Despite years of definitional debates, and attempts at clarification, Justice Stewart's "I know it when I see it" explanation is still probably the best description we have. This is likely because so many historical, legal, and cultural issues are involved in defining pornography. As McNair (1996) notes, "Pornography, and the elements said to comprise it, are shifting, slippery things, changing their content and meaning over time and between cultures (p. 57)."

Conceptualizing Pornography's Effects

Similar to the definitional debate about pornography, many groups have argued about the types of effect pornography has on society. Three groups in particular have engaged in this debate: liberals, feminists, and religious conservatives (Einsiedel, 1988).

The liberal view of pornography's effects is intimately tied up with their respect for free speech. They argue that unless a causal relationship can be shown between pornography and harm to women or children, then such content should be legal. Indeed liberals often point to the positive and supposedly causal cathartic effects of pornography as justification for its availability. Thus, for liberals, effect largely means an X causes Y type relationship.

In contrast to the causal view of effect adopted by liberals, anti porn feminists argue for an ideological conceptualization of effect. They claim that causality is beside the point, and that pornography doesn't cause anything, but literally enacts male dominance over women. As such, pornography's main effect is to "deny women full equality (Einsiedel, 1988: p. 113)."

Religious and political conservatives adopt a very similar ideological conception of effect. However, they choose to flip the feminist argument and argue that pornography is destroying (rather than enforcing) their cherished and institutionalized "Judaeo-Christian family values, which stress the virtues of the nuclear family, monogamous sexual relationships within marriage, and the reproductive rather than recreational functions of sexual behavior (McNair, 1996: p. 49)."

In sum, the liberal view of effects is tied to a causal "weak effects" tradition, while feminist and conservatives (although on different sides of the same fence) argue for a powerful "ideological" conception of effect.


The Powerful Effects of Pornography

As mentioned earlier, experimentalists and feminists took strong objection to the Johnson and Williams Commissions findings of limited pornography effects. As such, they set out to prove that powerful causal and ideological effects did exist, and that such results should not be ignored. This section will outline research in the following claimed powerful effects of pornography: (1. sexual arousal, (2. aggression, (3. desensitization, (4. attitudes towards women, (5. decline in family values, (6. causal model of rape, (7. feminist ideological effects, and (8. catharsis.

Sexual Arousal

A simple, yet consistently found powerful effect of both visual and literary pornography is its ability to sexually arouse males and females. This effect has been shown both mentally and physically.

Early research into arousal was conducted by Kinsey (1948) who found that males and females reported sexual arousal from material portraying nudity or sexual acts. Levitt (1969) attempted to take Kinsey's findings one step further by creating a scale of sexual arousal for men and women.

This self report data has been backed up by physiological research which shows that penile tumescence measures, urinary acid phosphate, vaginal vasocongestion, blood pressure, and genital temperature are all related to pornography exposure (Zuckerman, 1971; Kelley and Byrne, 1983).

Further studies have shown that arousal is caused by a combination of cognitive and imaginative processing (Geer and Fuhr, 1976; Przbyla and Byrne, 1984), and that arousal can result from self-generated erotic and non-erotic fantasies (Henson and Rubin, 1971).

Aggression

Related to the idea of arousal is the idea that exposure to pornography leads men to greater levels of aggression towards women. Bandura (1973) hypothesized that emotional arousal would intensify aggressive behavior. A number of experimental studies have tested this hypothesis.

Malamuth (1978) conducted a study using three male experimental conditions. One group would read aggressive pornography (depicting a rape), one nonaggressive pornography (loving interaction between a man and woman), and the third neutral stimuli (National Geographic articles). After exposure, all subjects were insulted by a female and were then put in a situation where they could aggress against this woman via the ostensible delivery of electric shocks. Half of the group was told it was permissible to be as aggressive as they wished (disinhibitory communication), while the other half were given a message to make them self conscious about aggression (inhibitory communication).

No results were found in the inhibitory group, but in the disinhibitory group the highest levels of aggression were recorded for those who had been exposed to the aggressive pornography.

Similar studies using the Buss paradigm (1961) where electrical shock against an experimental instigator is the operational definition of aggression, have been conducted by Donnerstein. For example Donnerstein and Berkowitz (1981) conducted an experiment placing males into one of four experimental film viewing conditions: aggressive pornography with positive outcome (depiction of a rape where the woman enjoyed the encounter), aggressive pornography with negative outcome (rape where the woman reacted negatively), nonagressive pornography (willing sexual intercourse), and a neutral stimuli. Before watching the film, participants were either angered or treated neutral by a female.

Results found that nonangered males who viewed the positive-aggressive film increased their aggression against the female. Among angered males, both the aggressive-positive and aggressive-negative films produced an increase in aggression towards the female instigator. From this, Donnerstein and Berkowitz conclude "that aggressive pornography can directly influence aggression against women (cited in Malamuth and Donnerstein, 1984)."

Using a similar design, Donnerstein attempted to gauge the effect of aggressive pornography relative to non-pornographic aggressive material. Male subjects were first angered or treated neutral by a female accomplice, and were then assigned to watch one of three films; aggressive pornography (similar in content to those used in previous studies), aggressive non-pornography (woman is tied up but no nudity or sex), and finally a consensual sex film.

Results found that the combination of angered subject and aggressive pornography produced the highest aggression levels. Significantly, the study also found that the aggressive non pornographic film produced higher levels of aggression than did the purely sexual film. This leads Donnerstein to again conclude that violent pornography is related to aggression against women, but that this may be a factor of the violence in the film, not its sexual content: "Again we see that aggressive pornography is a strong contributor to violence against women. The main factors in this aggressive facilitation, however, seems to be the aggressive nature of the film (Malamuth and Donnerstein, 1984: pp. 74-77)."

Desensitization

Two studies conducted by Donnerstein and Linz have found that prolonged exposure to so called "slasher films" desensitizes viewers to violence against women. Such films are not necessarily pornographic (indeed many are R rated) and usually portray extreme violence juxtaposed with mildly sexual arousing scenes.

In one study, Donnerstein and Linz (1985) showed 10 hours of R-rated slasher films, X-rated violent pornography, and X-rated nonviolent pornography to male subjects over the course of 5 days. The study found that the R-rated slasher films produced the greatest desensitization:

Initially, after the first day of viewing, the men rated themselves as significantly above the norm for depression, anxiety, and annoyance on a mood adjective checklist. After each subsequent day of viewing, these scores dropped until, on the fourth day of viewing, the males' levels of anxiety, depression, and annoyance were indistinguishable from baseline norms. (p. 34F).

Subjects were also found to believe the films less debasing and degrading to women and more enjoyable.

A similar study by Linz et al. (1988) exposed male groups to 8 hours of unedited feature length films. Groups saw slasher films, nonviolent comedies, sexually explicit nonviolent movies, or a no exposure control group. The study concluded that:

Sexually violent slasher films that were originally anxiety provoking and depressing became less so with repeated exposure. Men exposed to the slasher films also reported seeing less violence with continued exposure, and films found to be degrading to women were judged to be less so after prolonged exposure. (Krafka et al., 1997: p. 154)

It is important to note that in these studies, desensitization effects were strongest among R-rated slasher films which while containing sexual scenes, were not pornographic.

Attitudes Towards Women

Closely related to the desensitization studies, are experiments attempting to see if exposure to pornography leads to antisocial attitudes about women. These studies can be classified into two types, those looking at nonviolent pornography and those looking at violent pornography.

In a widely cited experiment, Zillmann and Bryant (1982) explored "the consequences of continued exposure to pornography on beliefs about sexuality in general and on dispositions towards women (p. 13)." In this experiment, 80 male and 80 female participants were randomly selected into one of four conditions. In the massive exposure group, participants watched 36 erotic films (roughly 5 hours of film) over a six week period. In the intermediate exposure group, participants saw 18 erotic films and 18 non-erotic films. The no exposure group saw 36 non-erotic films, and finally there was a control. All pornographic films shown were deemed nonviolent. After exposure, participants were introduced to a rape case and asked to recommend a prison sentence for the offense. Participants were also asked to indicate their support for the female liberation movement on a 0 (no support) to 100 (maximum support) scale.

The massive exposure group was found to have recommended significantly shorter prison terms for the rape case than all other groups. This was the case among both men and women. From this, Zillmann and Bryant conclude that "such exposure, it seems, made rape appear a trivial offense (p. 16)." The massive exposure group was also found to be significantly less supportive of the women's liberation movement.

In the Donnerstein and Linz (1985) desensitization study mentioned earlier, participants attitudes towards rape were also measured. After exposure, participants saw a documentary reenactment of a real rape trial, and were then asked to asses the female victim. Participants who had seen the R-rated slasher films found the victim to be more responsible for being raped, more worthless, and her injury less severe. Results were largely the same for participants who had seem the X-rated violent films. However, unlike Zillmann and Bryant's finding, participants exposed to nonviolent pornography showed no effects.

Two other studies done by Malamuth and Check (1980 and 1985) explored the relationship between pornographic rape stories and attitudes about rape in general. In both studies, male participants were randomly assigned to listen to short stories about a victim aroused by being raped, a victim abhorred by the rape, and a mutually desired sex story. In the first study, results showed that those men exposed to the aroused rape story believed that the woman had experienced less trauma than those in the other conditions. In the second study, results found that men who heard the aroused rape story were significantly more likely to believe that women enjoy rape.

These studies generally point to a link between violent pornographic material and antisocial views about women and rape (although it is unclear how much of this is due to violence alone). As we will discuss later, other than the Zillmann and Bryant study, little support is found for a similar link for nonviolent pornography.

Decline in Family Values

Zillmann and Bryant (1989) conducted an experiment to test nonviolent pornography's effect on traditional values about marriage and family. They randomly assigned participants into porn viewing and control groups, and exposed them to this material during hourly sessions over a six week period. After one week, participants were asked to complete a family values survey. Results found that endorsement of marriage as an important institution fell from 60 percent in the control group to 39 percent in the treatment group. The treatment group also wanted fewer children.

This and other similar studies have led Zillmann and Bryant to conclude that "those massively exposed to pornography will become distrusting of their partners in extended relationships . . . Another likely consequence is a growing dissatisfaction with sexual reality (cited in McNair, 1996: p. 77)." Similarly, Linz and Malamuth (1993) comment that exposure to pornography "fosters a lack of respect for social institutions such as the family and traditional sex roles for women (p. 17)."

Causal Model of Rape

Prominent feminist Diana Russell goes beyond the experimental evidence about pornography and aggression and attitudes towards women, and argues for a multivariate causal relationship between pornography and rape.

She begins her model by citing research which seems to indicate that a substantial portion of men have a propensity towards rape. For example, Briere and Malamuth (1983) found that of 356 male respondents, 60 percent indicated that under the right conditions, there was some likelihood that they would rape or use force against a woman. Similarly, Goodchilds and Zellman (1984) found that 50 percent of high school males interviewed believed it acceptable "for a guy to hold down and force her to have sexual intercourse in instances such as when 'she gets him sexually excited' or 'she says she's going to have sex with him and then changes her mind."

From this premise, Russell argues that pornography predisposes some males to want to rape women by:

1. Pairing sexually arousing stimuli with rape.
2. Increasing males self-generated rape fantasies.
3. Sexualizing dominance and submission.
4. Creating an appetite for increasingly stronger material.

She also finds that pornography undermines males internal inhibitions to act out rape fantasies, and that it undermines potential victims ability to avoid or resist rape (Russell, 1993). Supporting these elements of her causal model she borrows heavily from the experimental research on aggression, desensitization, and attitudes towards women cited above.

Oddly enough, Russell concludes her causal model for pornography and rape by citing correlational evidence. For example, she points to a study done by Baron and Straus (1984) which found a significant correlation (+0.64) between state rape rates and the circulation rate of pornographic magazines in those states. The use of this evidence is rather queer, as any good statistician will note that correlation does not imply causation.

Ideological Effects

Operating largely outside of experimental, survey, and correlational analyses, feminist scholars have developed an ideological view of pornography as more than a simple causal effect, but as a self sustaining reality. This view grows out of the traditional feminist critique of patriarchy, which finds that the oppression of women is an institutionalized and socially constructed tool which men use to maintain the status-quo. As Itzin (1992) summarizes:

In Western societies, women are oppressed on the basis of race and class and sexuality and disability. Within this system of sexism, male power -- or male supremacy -- is institutionalized so that men as a group have access to economic, social, sexual and political power that women do not have.

From this perspective, it is but a short jump to find that pornography is a major tool used by the male hierarchy to keep women in their place. Thus, Dworkin (1988) finds that "Pornography is the material means of sexualizing inequality; and that is why pornography is a central practice in the subordination of women." In a similar fashion, Smith argues that pornography is just another aspect of a capitalist male hegemony: "Pornography solidifies white, male, heterosexual fantasies, and then commoditizes them (1988: p. 179)."

Key within these conceptualizations is the idea that pornography shows women to enjoy violence, subordination, and degradation, in other words the methods by which hierarchy punishes and maintains its power. Thus pornography teaches women that they are mere objects for male pleasure and domination. Therefore, women are socialized to this view, and pornography achieves its hegemonic ends. As Dworkin (1988) concludes:

Pornography is the institution of male dominance that sexualizes hierarchy, objectification, submission, and violence. As such, pornography creates inequality, not as an artifact but as a system of social reality; it creates the necessity for the actual behaviors that constitute sex inequality.

This conclusion -- that pornography is more than a simple effect, but is rather a totalizing force of discrimination -- led Dworkin and MacKinnon to lobby the city of Minneapolis to pass an anti-pornography censorship bill. They essentially argued that pornography constituted a form of discrimination against women, not unlike Jim Crow laws used against blacks. As a result, women, as a group, should receive civil rights protections against pornography. As the Minneapolis Ordinance states (and also provides an excellent summation of the feminist ideological view of pornography):

Pornography is central in creating and maintaining the civil inequality of the sexes. Pornography is a systematic practice of exploitation and subordination based on sex which differentially harms women. The bigotry and contempt it promotes, with the acts of aggression it fosters, harm women's opportunities for equality of rights in employment, education, property rights, public accommodations and public services; create public harassment and private denigration; promote injury and degradation such as rape, battery and prostitution and inhibit just enforcement of laws against these acts; contribute significantly to restricting women from full exercise of citizenship and participation in public life, including in neighborhoods; damage relations between the sexes; and undermine women's equal exercise of rights to speech and action guaranteed to all citizens under the constitutions and laws of the United States and the State of Minnesota. (cited in Ferguson, 1995: p. 677)

The ordinance was passed by the city council in 1983 but was vetoed by the mayor. However, a revised version of the law was passed and signed into law by the city of Indianapolis in 1984. The following year, in the case of American Booksellers v. Hudnut (1986) the ordinance was struck down as and unconstitutionally vague restriction on protected speech.

Catharsis

At first, it may seem odd to place catharsis under the heading of "powerful effects." After all catharsis studies generally show that pornography prevents harmful effects like rape and other sex crimes. From this, one might argue that catharsis proves the "limited effects" of pornography. A better way to think of catharsis is as a powerful "limiting effect" against sexually deviant behavior. Therefore, it is properly referred to as a powerful effect.

A number of cathartic effects have been found for pornography, but perhaps the most widely cited is the so called "Danish experience." In the 1960's Denmark experienced a "porno wave", but rather than censoring this content, in 1967 the government lifted all restriction on pornography (save a 16 year old age limit for purchasing porn). Yet rather than experiencing a wave of sex crimes as some had predicted, sex crimes actually declined. For example, Kutchinsky (1970; 1985; 1987; 1991) found that from 1965 to 1982 sex crimes against children declined from 30 per 100,000 in '65 to about 5 per 100,000 in '82. Similar evidence is found for rape rates. Kutchinsky concludes that this is likely the effect of pornography providing potential sex offenders an alternate means of sexual satisfaction, most likely through masturbation.

Another example of a nation with high amounts of pornography yet low sex crime rates is Japan. As Abramson and Hayashi (1984) have found, pornography in Japan is often featured in general interest newspapers and magazines, and can be seen on prime time television. Not only is porn widely available but much of its adult content depicts the bondage and rape of young women. "In fact, one of the best ways to ensure the success of a Japanese adult film is to include the bondage and rape of a young woman (Abramson and Hayashi, 1984: p. 178)." Despite this, Japan's rape rate is roughly 14 times lower than that of the U.S.'s (2.4 rapes per 100,000 in Japan compared to 34.5 in the U.S.). This discrepancy can not be explained by variance in laws, or Japanese women's reluctance to report rape. Instead, the

Japanese view the availability of such stimuli as a cathartic valve. It is presumed to provide vicarious satisfaction of a socially unacceptable behavior. In a culture that endorses strict codes of behavior and highly defined roles, the depiction of rape also provides a context in which Japanese men can vicariously abandon all of the explicit signposts of good behavior. (p. 182).

Continuing with international evidence, Faust (1982) studied countries with the most and least equality achieved between men and women. She found that in nations like the U.S. and the Scandinavian countries which highly value women's equality, pornography was widely available. In contrast, in countries repressive towards women, like Iran, Saudi Arabia, and the former Soviet Union, little or no pornography was available.

Another cathartic effect for pornography is found in data about child sex offenders and rapists. Child sex offenders have been shown to have had very little, if any exposure to pornography (Byrne and Kelley, 1984; Faust, 1982). Evidence has also shown that a majority of rapists come from sexually repressive family backgrounds (Goldstein and Kant, 1973; Byrne and Kelley, 1984).

In all of these cases, the cathartic effect of pornography is believed due to a substitution effect, by which potential sex offenders receive sexual gratification from pornographic content, rather than from criminal acts against individuals.


Limited Effects

Limited effects data for pornography are largely confined to experiments which find no relationship between exposure to pornography and some dependent variable like aggression or attitudes towards women. This is especially true of studies measuring men and women's attitude changes after exposure to nonviolent and violent pornography.

Nonviolent Pornography Exposure

Almost no studies have been able to replicate Zillmann and Bryant's (1982) finding of negative attitudes towards women after exposure to nonviolent pornography. For example, Padgett and Brislin-Slutz (1987) conducted a nearly identical study, massively exposing male and female participants to 5 straight days of nonviolent pornography, and then assessing their attitudes towards women and rape. Their results found no difference between pre and post test measures, and no difference between the porn viewing group and the control.

Similarly, many other studies -- including the Donnerstein and Linz (1985) study described earlier -- exposing participants to several experimental conditions (violent porn, nonviolent porn, control) have found that exposure to nonviolent porn produces few or no adverse attitudes towards women. From a review of this literature, Linz (1989) notes "We would have to conclude that the data, overall, do not support the contention that exposure to nonviolent pornography has significant adverse effects on attitudes toward rape as a crime or more general evaluations of rape victims (p. 74)."

Violent Pornography Exposure

Despite Donnerstein and Linz's conclusion that violent pornography likely has some effect on negative attitudes towards women, a number of studies have found no such results.

Malamuth, Reisin, and Spinner (1979) exposed male and female participants to magazine portrayals of aggressive (sadomasochism and rape) and nonagressive pornography. Next, they were exposed to a videotaped interview of an actual rape victim, and then asked to answer a questionnaire assessing perceptions of the victim, and attitudes towards rape. Results found no significant differences between participants exposed to the violent pornography and those exposed to the nonviolent pornography.

In a similar study, Malamuth, Haber, and Feshbach (1980) exposed participants to either a sadomasochistic or nonviolent pornographic story. Next, participants read a description of a rape where the victim clearly opposed the assault, and were then asked to recommend a prison sentence for the offender. Results yielded no main effects for exposure to the sexually violent story and attitudes towards rape as measured by the sentencing question.

Finally, Krafka et al. (1997) exposed female participants to either feature length violent pornography, nonviolent pornography, or mildly sexual slasher films. Participants were pre and post tested for self-perception attitudes like self-esteem and fear of victimization. Results showed no significant reductions in self esteem between the experimental groups.

Taken together, these results cast doubt on the asserted link between violent pornography and negative/antisocial attitudes towards women.


Criticisms of the Experimental Results

A number of very cogent criticisms have been leveled against the experimental results described above. These criticisms are particularly relevant considering that many anti porn feminists and conservatives site the experimental literature as proof that pornography does have harmful effects.

Generalizability

Perhaps the most cogent criticism of the experimental literature is the inability to generalize results beyond the college students who overwhelmingly make up the participants in these studies. Indeed, the vast majority of results on the effects of pornography have been obtained from only a handful of U.S. universities (notably the University of Wisconsin, UCLA, and UC Santa Barbara). Studies have shown that students who volunteer for such studies are more liberal, more sexually experienced, and have less objections to pornography than do nonvolunteers (Einsiedel, 1992: p. 268). This in addition to the obvious fact that most of the population is not college aged.

Artificial Environment

In the real world few people are exposed to pornography in groups. Instead, pornography is usually consumed individually in the comfort of the home. Further, experiments testing aggression after exposure to pornography provide participants with the completely artificial option of shocking an instigator. Brannigan and Goldenberg (1987) argue that such experimental designs also provide no real world sanctions to the expression of negative attitudes.

Differing Stimuli and Definitions

From experiment to experiment a great deal of difference can be found in the stimuli provided to participants. In most cases researchers use different pornographic films which they independently decide are violent - nonviolent, permissive - nonpermissive, consensual - non-consensual, etc. Thus comparing a study which used Debby Does Dallas to a similarly designed study using Long Dong Silver may be spurious (Linz, 1989: pp. 79-80).

No Results - No One Knows

Unfortunately, only studies which report significant findings are normally published. As a result, a great number of studies showing no effects, and thus supporting the limited effects model, never make it to public view (Pally, 1994: p. 28).


Other Approaches to Studying Pornography

The powerful vs. limited effects debate about pornography has led to an often personal and political stalemate, where feminists and conservatives argue for powerful effects, while experimental researchers take a more cautious stance. As a result of this effects quagmire, a number of scholars have chosen to study pornography for its entertainment value and for its personal and political uses.

Pornography as Entertainment

Given the fact that the pornography is a $10 billion a year industry (McDonald, 1997), some consumers must be finding its content entertaining. Despite this, almost no studies have attempted to describe the attributes that lead to enjoyment of pornography.

An interesting exception, is the work of Lopez and George (1995) who set out to understand what makes males and females enjoy pornography. They conceptualized pornographic enjoyment as a function of two things. First, as a scale for erotophobia (fear of the erotic) vs. erotophilia (enjoyment of the erotic) which is comprised of variables relating to sexual experience, sexual inhibitions, and sex guilt, and secondly as a function of gender-specific sex norms (i.e. men are more likely to initiate sex, men enjoy pornography more, etc.). These variables were measured by a pretest of 26 male and 12 female volunteers. After the pretest, participants were individually exposed to pornographic slides, and asked to rate each for enjoyment. Results showed that erotiphilic men enjoyed the pornography more than erotiphilic women whose gender based norms inhibited their enjoyment (p. 279).

Uses and Gratifications of Pornography

The classic formulation of the Uses and Gratifications theory is that it asks not "what the media do to people" but "what people do with the media." As such, uses and gratifications is perfectly suited to asking why people use pornography, and what they get out of this use.

A number of studies have inventoried particular uses of pornography. For example, a Newsweek poll found that 52 percent of respondents believed that sexually explicit content provided information about sex and that 61 percent found such material entertaining (Press et al., 1985). Similar studies have found that individuals find adult movies humorous, and as material for fantasizing about unrealistic women (Winick, 1971).

In a more recent study, Perse (1994) asked what reasons college students gave for using erotica? She found four specific uses: (1. sexual enhancement - related to information and foreplay, (2. diversion - related to escape, relaxation, and entertainment, (3. sexual release - related to fantasizing, and finally (4. substitution, or using pornography as a substitute for sex (i.e. masturbation). Of these uses, diversion was found to be the most strongly endorsed.

Reception and Oppositional Readings of Pornography

Similar to uses and gratifications, reception theory asks how people receive and decode media messages. Reception theory is also interested in the author's encoding process.

In terms of pornography research, these ideas have been picked up by feminist scholars who claim that pornography -- far from being evil -- is used oppositionally by some, and as a legitimating and empowering tool by oppressed or marginalized groups. In terms of oppositional readings, Willis (1984) questions why females must read pornography as a subordinating and degrading text. Why can't a woman read pornography as an expression of her own repressed sexual fantasies?

A woman who is raped is a victim; a woman who enjoys pornography (even if that means enjoying a rape fantasy) is in a sense a rebel, insisting on an aspect of here sexuality that has been defined as a male preserve. Insofar as pornography glorifies male supremacy and sexual alienation, it is deeply reactionary. But in rejecting sexual repression and hypocrisy -- which have inflicted even more damage on women than on men -- it expresses a radical impulse. (Willis, cited in McNair, 1996: 97)

In a similar way, marginalized groups like gays and lesbians can produce their own pornography, thus providing material which questions the hegemony of Judeo-Christian sexual norms. Unlike the anti-porn feminist viewpoint which sees pornography as a tool of male repression, this conception sees pornography as a tool of expression and legitimation (McNair, 1996).


Conclusion

This paper has provided an overview of the limited effects - powerful effects debate about pornography. From this presentation, it should be clear that just like debates about television violence or the effect of the mass media in general, there are no clear answers. As such, it would seem that the best conclusion one can reach about the effect of pornography is that it "does not serve as a necessary and sufficient cause of audience effects, but rather functions among and through a nexus of mediating factors and influences (Klapper, 1960)." Thus bringing us full circle, back to the limited effects conclusion that sparked pornography research in the first place.
