Porn,Peers, and Performing Oral Sex: The Mediating Role of Peer Norms on Pornography’s Influence Regarding Oral Sex

ABSTRACT

The goal of this study was to offer insights into how pornography use might be linked to young adults’ sexual experiences via the mediating role of peer norms (i.e., their perceptions of what same-sex peers do sexually). We focused on oral sex behavior, as it is common in pornography and among young people. Young adults (N = 349; ages 19–30; 54% female) were recruited through a crowdsourcing website. Participants completed an anonymous online survey about the frequency that they observed various sexual behaviors in online pornography, the frequency that they engaged in these behaviors, and their perceptions of the frequency that their peers engaged in these behaviors. Frequency of viewing cunnilingus (men) or fellatio (women) in pornography predicted how often they engaged in oral sex, and this association was mediated by their perceptions of how frequently their peers engaged in oral sex. Peer norms did not mediate how frequently they received oral sex. Findings are discussed in terms of implications for understanding how pornography may relate to young people’s social norms surrounding oral sex and their performance of sexual behaviors, as well as for understanding generally how media consumption relates to adoption of media behaviors through suggesting a social norm.     

The Role of Probability and Intentionality in Preschoolers' Causal Generalizations

Three experiments examined whether preschoolers recognize that the causal properties of objects generalize to new members of the same set given either deterministic or probabilistic data. Experiment 1 found that 3- and 4-year-olds were able to make such a generalization given deterministic data but were at chance when they observed probabilistic information. Five-year-olds reliably generalized in both situations. Experiment 2 found that 4-year-olds could make some probabilistic inferences, particularly when comparing sets that had no efficacy with sets in which some members had efficacy. Children had some difficulty discriminating between completely effective sets and stochastic ones. Experiment 3 examined whether 3- and 4-year-olds could reason about probabilistic data when provided with information about the experimenter's beliefs about causal outcomes. Children who were more successful on standard false-belief measures were more likely to respond as if the data were deterministic. These data suggest that children's probabilistic inferences develop into early elementary school, but preschoolers might have some understanding of probability when reasoning about causal generalization.     

The Blicket Within: Preschoolers' Inferences About Insides and Causes

Four experiments examined children's inferences about the relation between objects' internal parts and their causal properties. In Experiment 1, 4-year-olds recognized that objects with different internal parts had different causal properties, and those causal properties transferred if the internal part moved to another object. In Experiment 2, 4-year-olds made inferences from an object's internal parts to its causal properties without being given verbal labels for objects or being shown that insides and causal properties covaried. Experiment 3 found that 4-year-olds chose an object with the same internal part over one with the same external property when asked which object had the same causal property as the target (which had both the internal part and external property). Finally, Experiment 4 demonstrated that 4-year-olds made similar inferences from causal properties to internal parts, but 3-year-olds relied more on objects' external perceptual appearance. These results suggest that by the age of 4, children have developed an understanding of a relation between an artifact's internal parts and its causal properties.     

Dialogue and Synthesis: Developing Consensus in Visitor Research Methodology

ABSTRACT

This brief synthesis presents the main points of agreement between Dawson and Jensen's article, “‘Towards a ‘Contextual Turn’ in Visitor Studies: Evaluating Visitor Segmentation and Identity-Related Motivations” (this issue) and Falk's reply, “Contextualizing Falk's Identity-Related Visitor Motivation Model” (this issue), and it highlights important considerations for future research.     

The Role of Rape Myth Acceptance and Psychopathy in Sexual Assault Perpetration

Perpetrators of sexual aggression consistently report higher scores on measures of psychopathy and acceptance of rape myths relative to nonperpetrators. However, less is known about psychopathy among nonincarcerated individuals and the relation between the two constructs has not been empirically examined among college perpetrators. To address this gap, both constructs were measured in a sample (N?=?308) of college men. Rape myth acceptance was positively correlated with psychopathy, and perpetrators scored higher on both constructs. Myths transferring responsibility to victims were related to Factor 1 psychopathy (i.e., callous and manipulative traits). The myth that “rape is trivial” was associated with Factor 1 and Factor 2 (i.e., impulsive and antisocial behavior), possibly suggesting that this myth is related to a larger tendency to excuse aggressive behavior. Although both constructs distinguished perpetrators when considered individually, rape myth acceptance did not explain unique variance in the presence of psychopathy.     

Coping with Intimate Partner Violence: Battered Women's Use and Perceived Helpfulness of Emotion-Focused Coping Strategies

This study investigated intimate partner violence (IPV) victims' emotion-focused coping efforts, as well as their retrospective ratings of the perceived helpfulness of these efforts, in the context of a longitudinal study of battered women's experiences over time. Four hundred and six primarily African American, low-income battered women who had experienced IPV within the previous 12 months were interviewed. Patterns of coping use and perceived helpfulness were explored. The correlation between prevalence of use of emotion-focused coping strategies and perceived helpfulness of these strategies was examined, and results showed that the strategies used by more battered women were less helpful in dealing with feelings about abuse. Implications for clinical interventions with battered women are discussed.     

Aggression in the Laboratory: Problems with the Validity of the Modified Taylor Competitive Reaction Time Test as a Measure of Aggression in Media Violence Studies

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity.     

Exploring block construction and mental imagery: Evidence of atypical orientation discrimination in Williams syndrome

The visuospatial perceptual abilities of individuals with Williams syndrome (WS) were investigated in two experiments. Experiment 1 measured the ability of participants to discriminate between oblique and between nonoblique orientations. Individuals with WS showed a smaller effect of obliqueness in response time, when compared to controls matched for nonverbal mental age. Experiment 2 investigated the possibility that this deviant pattern of orientation discrimination accounts for the poor ability to perform mental rotation in WS (Farran, Jarrold, & Gathercole, 2001). A size transformation task was employed, which shares the image transformation requirements of mental rotation, but not the orientation discrimination demands. Individuals with WS performed at the same level as controls. The results suggest a deviance at the perceptual level in WS, in processing orientation, which fractionates from the ability to mentally transform images.
