Adolescents' Exposure to Sexually Explicit Internet Material and Sexual Preoccupancy: A Three-Wave Panel Study

The main aim of this study was to investigate whether adolescents' use of sexually explicit Internet material (SEIM) increased their sexual preoccupancy (i.e., a strong cognitive engagement in sexual issues). Further, we wanted to know (a) whether subjective sexual arousal mediated a potential influence of exposure to SEIM on sexual preoccupancy and (b) whether this process differed between male and female adolescents. Over the course of one year, we surveyed 962 Dutch adolescents aged 13–20 years three times. Structural equation modeling showed that exposure to SEIM stimulated sexual preoccupancy. This influence was fully mediated by subjective sexual arousal from SEIM. The effect of exposure to SEIM on subjective sexual arousal did not differ between male and female adolescents. The findings suggest that a sexualized media environment may affect adolescents' sexual development beyond traditionally studied variables, such as sexual attitudes and sexual behavior.     

Adolescents’ Exposure to Sexually Explicit Internet Material and Sexual Satisfaction: A Longitudinal Study

The aim of this study was to investigate, within a social comparison framework, the causal relationship between adolescents’ use of sexually explicit Internet material (SEIM) and their sexual satisfaction. In addition, we tested which adolescents were most susceptible to a potential influence of SEIM on sexual satisfaction. Between May 2006 and May 2007, we conducted a three‐wave panel survey among 1,052 Dutch adolescents aged 13–20. Structural equation modeling revealed that exposure to SEIM consistently reduced adolescents’ sexual satisfaction. Lower sexual satisfaction (in Wave 2) also increased the use of SEIM (in Wave 3). Moderator analyses showed that the negative effect of SEIM on sexual satisfaction was stronger for adolescents who had no or limited sexual experience as well as for adolescents who perceived the majority of their peers to be sexually inexperienced. The effect of exposure to SEIM on sexual satisfaction did not differ among male and female adolescents.     

Porn Sex Versus Real Sex: How Sexually Explicit Material Shapes Our Understanding of Sexual Anatomy,Physiology, and Behaviour

Given that consumption of sexually explicit material (SEM) and sexual behaviour are inextricably linked, the purpose of this study was to determine whether the frequency of SEM consumption predicts knowledge of sexual human anatomy, physiology, and typically practiced sexual behaviour. A secondary purpose was to investigate self-perceived effects of SEM consumption and whether participants report SEM as a positive or negative contributor to various aspects of life. Using a modified version of the Pornography Consumption Questionnaire and the Falsification Anatomy Questionnaire, we determined that contrary to expectations, frequency of SEM exposure did not contribute to inaccurate knowledge of sexual anatomy, physiology, and behaviour. Rather, the opposite relationship was found. However, in concert with previous literature, participants reported greater positive self-perceived effects of SEM consumption than negative effects.     

Effects of Violent Versus Nonviolent Video Games on Children's Arousal, Aggressive Mood, and Positive Mood

This study investigated the relationship between violent video games and children's mood. A total of 71 children aged 8 to 12 years played a paper-and-pencil game, a nonviolent video game, and a violent video game. Results indicate that arousal, as measured by heart rate and self-reported arousal, increased significantly after playing the violent video game, as compared with the other two game conditions, with girls reporting more arousal than did boys. There was no significant increase in aggressive mood scores for either boys or girls after playing the violent game. Positive mood, as measured by positive affect, showed no significant increases or decreases after playing either video game. However, positive mood, as measured by general mood, showed a significant increase after playing the violent game for both boys and girls, but only as compared with the paper-and-pencil game. Results are interpreted in terms of social learning and cognitive information processing theories of aggression.     

Gender and Self-Reported Sexual Arousal in Response to Sexual Stimuli: A Meta-Analytic Review

Social constructionist theories and sociobiological perspectives have led to increased interest in gender differences in sexual behavior. This study involved a meta-analysis of gender differences in sexual arousal in response to sexual stimuli. Forty-six studies in which participants were presented with a sexual stimulus depicting males and females and in which participants responded using a self-report measure of arousal were compiled, and 62 independent effect sizes were aggregated. An overall effect size of d = .31 showed a small to moderate-sized gender difference in sexual arousal with men reporting more arousal than women across all studies. There was significant variation in the effect sizes, though, which was only partially explained by variables coded from the studies. It was found that the gender difference was slightly larger for studies using pornographic vs. erotic stimuli, was larger for studies where participants were tested in a private setting or small group compared to a large group, and was much larger for college age participants compared to those who were older than college age. Generally, the pattern of results provided more support for predictions from social influence theories compared to sociobiological theory.     

An Experimental Investigation of the Interactive Effects of Alcohol and Sexual Arousal on Intentions to Have Unprotected Sex

Two studies were conducted to test the efficacy of compliments as a compliance tactic and to explore whether liking could account for their effectiveness. Both studies provided evidence that compliments increased compliance relative to a control condition. Although receiving a compliment did tend to increase liking of the requestor, this increased liking was not responsible for enhanced levels of compliance. This research provides some of the first direct evidence of the effectiveness of compliments as a means of securing compliance and provides data challenging the mechanism most commonly assumed to be responsible for its effects.     

Gender Differences in Escapist Uses of Sexually Explicit Internet Material: Results from a German Probability Sample

The intensity of using sexually explicit internet material (SEIM) is contingent on users’ gender. However, gender differences in the motivations for watching SEIM have not yet been comprehensively explored. Drawing on a representative survey of German internet users, we therefore analyze how women and men use SEIM to satisfy escapist needs. Lower life satisfaction, the lack of a committed relationship, and feelings of loneliness contribute to predicting the frequency of using SEIM among men. Loneliness likewise fosters the consumption of SEIM among women, yet the effect is less pronounced. For female internet users, consumption of SEIM even increases in committed relationships and rather indicates a comparably high level of life satisfaction than dissatisfaction with life circumstances. Gender hence substantially moderates the connection between need structures and the consumption of SEIM.     

The Effects of Social Influence on Perceptual and Affective Reactions to Scenes of Sexual Violence1

In 2 experiments, we examined the effect of social influence (discussion and modeling) on men's and women's perceptual and affective reactions to a sexually violent film scene depicting gang rape. In Experiment 1, women who discussed the film rated the perpetrators as more responsible compared to participants in all other conditions. Men who did not discuss the film reported higher levels of positive affect compared to participants in all other conditions. In Experiment 2, men and women were affected by the social influence manipulation similarly. As predicted, participants differed in their attributions of responsibility depending on a confederate's response to the film scene. Participants who heard a confederate say that the men in the film were responsible for the rape rated these men as relatively more responsible than did participants in a neutral confederate condition or in a condition in which the confederate said that the woman in the film was responsible for the rape.     

Sexually Explicit Media and Sexual Risk Behavior in a Sample of Men Who Have Sex with Men in Norway

The aim of this study was to explore the association between the consumption of sexually explicit media (SEM) depicting condom and non-condom use and HIV/STI-related sexual risk behavior among men who have sex with men (MSM) in Norway. We also explored whether the association between SEM consumption and STI-related sexual risk behavior is mediated by men’s sexual self-esteem and/or condom use self-efficacy. A cross-sectional online survey study was carried out in Norway in 2012. The final sample comprised 529 MSM in Norway. There was a bivariate association between the use of SEM picturing condom use and less STI-related sexual risk behavior. Further, the association between SEM consumption and sexual risk behavior was mediated by condom use self-efficacy. However, SEM did not influence sexual risk behavior via sexual self-esteem. The results offer important cross-cultural validation of recent comparative data from the US and may be used to promote HIV/STI prevention, in the sense that the actors in SEM may serve as role models in managing condom use in sexual contexts.     

The Influence of Feedback on Mood: Linear Effects on Pleasantness and Curvilinear Effects on Arousal

We investigated the effects of feedback (grades) on two primary mood dimensions - Pleasantness and Arousal. We hypothesized that (a) cognitive comparisons of feedback to multiple standards yield cognitive appraisals of feedback sign, and that (b) feedback sign has a linear effect on harm/benefit appraisal, which influences mood Pleasantness, and a curvilinear effect on need for action appraisal, which influences Arousal. In Study 1 (N = 281), grades (a proxy for the sign of feedback-norm discrepancy) had a linear relationship with Pleasantness and a U-shaped relationship with Arousal. In addition, subjects who received grades had higher Arousal than control subjects. Study 2 (N = 226) replicated the results of Study 1 and showed that after controlling for the relationship of grades with Pleasantness and Arousal, the sign of feedback-expectation discrepancy (a second standard) also had a linear relationship with Pleasantness and a U-shaped relationship with Arousal.     

Effects of Arousal on Everyday Memory

The notion of an unidimensional continuum of arousal is difficult to sustain, as is the universality of predictions from the Yerkes-Dodson law. A brief his- torical account of how these difficulties have arisen is provided, as well as sketches of some theoretical alternatives that have appeared in the past 10 years. It is argued that this more recent theorizing can supply explanatory constructs to bring order to the data on the relation of increases in arousal to memory performance. The argument is illustrated by an analysis of a number of studies involving everyday memory performance, studies involving encod- ing of eyewitness memories or retrieval of complex motor sequences.     

Effects of Television Violence on Memory for Violent and Nonviolent Advertising

This study investigated the impact of television violence on memory for advertising, taking into account the possible role of viewer hostility arousal in this context. Experimental participants were exposed to advertising placed within a violent or a nonviolent film clip. One advertisement had 2 versions–violent and nonviolent–and was presented with 2 other nonviolent filler advertisements. Participants completed a mood questionnaire before and after being exposed to the television material, tested for memory for the embedded advertising and asked to rate the film clips and the advertisements using a set of evaluative scales. The nonviolent version of the target advertisement was less well remembered when placed in the violent film than in the nonviolent film, supporting Bushman and Bonacci (2002). In contrast, the violent version of the target advertisement was remembered much better than the nonviolent version when placed in the violent film sequence. Participants' hostility scores were higher only after watching the violent film, and associated with an impairment in the memory of the nonviolent advertisements, while enhancing the memory of the violent advertisement, thus providing some support for Bushman's (1998a) hostile-thought hypothesis.     

Lazos que Atan: The Influence of Normative Gender Beliefs on Sexual Risk Behaviors of Latino Men and Women

Not all Latino men and women conform to proscribed gender roles. Nonetheless, their sexual risk taking may well be influenced by traditional beliefs concerning these roles. We explored the relationship between gender beliefs that are normative in Latino culture, and the sexual risk behaviors of 152 Latino men and women who participated in a behavioral rapid needs assessment survey in Houston, TX. Path—analytic results indicate that normative gender beliefs are influenced by respondents' sex and their levels of acculturation and that these 2 variables influence sexual risk behaviors, including unprotected sex and multi partnerism. Our results suggest that beliefs about gender influence sexual behavior and, therefore, are an important factor that should be considered in understanding sexual risk taking among Latinos.     

How to be a Normative Expressivist1

Abstract. Expressivism can make space for normative objectivity by treating normative stances as pro or con attitudes that can be correct or incorrect. And it can answer the logical challenges that bedevil it by treating a simple normative assertion not merely as an expression of a normative stance, but as an expression of the endorsement of a proposition that is true if and only if that normative stance is correct. Although this position has superficial similarities to normative realism, it does full justice to the core expressivist thesis that, at bottom, a normative assertion expresses a normative stance rather than a factual belief.     

The Effects of Anticipated Informational and Normative Influence on Perceptions of Hypothetical Opinion Change

Two experiments addressed the role of anticipated informational or normative influence on perceptions of hypothetical opinion change in the context of either an intellective or judgmental task. The findings from Experiment 1 indicate that informational and normative influence processes are perceived as being differentially effective in changing people's opinions about a judgmental task but not about an intellective task. Experiment 2 explores some possible causes of these findings.     

Attitudinal and Normative Factors as Determinants of Gay Men's Intentions to Perform AIDS-Related Sexual Behaviors: A Multisite Analysis1

The purpose of this study was to test the applicability of the theory of reasoned action as a basis for understanding and predicting gay men's intentions to perform AIDS-related sexual behaviors. A total of 314 self-identified gay or bisexual men from Seattle, Denver, and Albany participated in the study. They were asked to indicate their intentions to perform 15 specific sexual behaviors chosen to represent different degrees of risk of contracting AIDS or other sexually transmitted diseases. In addition, they were asked to respond to items measuring the attitudinal and normative considerations regarding each behavior. As expected, the results showed that the gay men's intentions were significantly predicted by the two factors. More interesting, it was found that, although attitudes are consistently the more important determinants of intentions for all the respondents, the importance of normative considerations varies across cities. This difference in normative considerations is interpreted in light of the differences in the structure of the three gay communities. Implications for designing sample-specific intervention programs are discussed.     

唤醒度对汉语情绪词情绪启动效应的影响

使用词汇情绪启动的实验范式,通过两个行为实验探讨了不同SOA(100ms、300ms和500ms)条件下情绪唤醒度在情绪启动效应中的作用,以及情绪启动效应是否受到任务形式的影响。结果发现,在情绪效价判断任务中,SOA为100ms时高唤醒和低唤醒启动词都出现了情绪启动效应,SOA为300ms时只有高唤醒启动词出现了情绪启动效应。在真假词判断任务中,无论高唤醒还是低唤醒启动词都没有出现情绪启动效应。唤醒度是影响词汇情绪启动效应的重要因素,但这种效应不是完全自动化的过程,会受到SOA和任务导向的影响。情绪启动效应可能来自于启动词与目标词在反应趋向上的一致性趋势。     

Sexual Priming, Gender Stereotyping, and Likelihood to Sexually Harass: Examining the Cognitive Effects of Playing a Sexually-Explicit Video Game

The present study examines the short-term cognitive effects of playing a sexually explicit video game with female “objectification” content on male players. Seventy-four male students from a university in California, U.S. participated in a laboratory experiment. They were randomly assigned to play either a sexually-explicit game or one of two control games. Participants’ cognitive accessibility to sexual and sexually objectifying thoughts was measured in a lexical decision task. A likelihood-to-sexually-harass scale was also administered. Results show that playing a video game with the theme of female “objectification” may prime thoughts related to sex, encourage men to view women as sex objects, and lead to self-reported tendencies to behave inappropriately towards women in social situations.     

情绪效价和唤醒对熟悉性和回想的不同影响

本研究检验了情绪的效价和唤醒对记忆提取阶段熟悉性过程和回想过程的影响及其心理机制。结果发现,编码阶段无分心任务时,积极图片的高、低自信再认准确率均高于消极图片,而唤醒对于高自信再认准确率的影响只限于消极图片;在编码阶段设置分心任务时,发现积极和消极的高唤醒图片的高自信再认准确率显著高于低唤醒图片。这些结果说明情绪的效价影响了熟悉性和回想两类记忆过程,而唤醒只影响回想过程,效价效应是编码阶段被试调用认知资源对积极图片进行精细加工的结果,而唤醒对回想过程的影响是自动编码高唤醒刺激细节的结果。     

外显自尊脑机制研究实验材料的筛选

本研究试图检测出与自尊相关的自我评价,以此作为外显自尊脑机制研究的指标,因此对实验材料进行筛选.以积极触及自尊符合词、消极触及自尊不符合词、非自尊符合词和非自尊不符合词作为实验材料,采用"人物对象--人格形容词"评价范式,让180名在校大学生用这四类词语对"自我"和"他人"进行评价.得到以下结果:(1)与自尊相关的自我评价体现为个体用积极或者消极触及自尊词进行的自我评价;(2)个体对正性他人的评价可以作为一个参照指标,由于个体对负性他人评价的一致性较低,因此在脑机制研究中的"人物对象"不包括负性他人.
