The influence of sexually explicit Internet material and peers on stereotypical beliefs about women's sexual roles: similarities and differences between adolescents and adults

Previous research on the influence of sexually explicit Internet material (SEIM) on adolescents' stereotypical beliefs about women's sexual roles has three shortcomings. First, the role of peers has been neglected; second, stereotypical beliefs have rarely been studied as causing the use of SEIM and the selection of specific peers; and third, it is unclear whether adolescents are more vulnerable to the effects of SEIM than adults. We used data from two nationally representative two-wave panel surveys among 1,445 Dutch adolescents and 833 Dutch adults, focusing on the stereotypical belief that women engage in token resistance to sex (i.e., the notion that women say "no" when they actually intend to have sex). Structural equation modeling showed that peers who supported traditional gender roles elicited, both among adolescents and adults, stronger beliefs that women use token resistance to sex. Further, the belief that women engage in token resistance predicted adolescents' and adults' selection of gender-role traditional peers, but it did not predict adolescents' and adults' use of SEIM. Finally, adults, but not adolescents, were susceptible to the impact of SEIM on beliefs that women engage in token resistance to sex.     

Characteristics and motives of adolescents talking with strangers on the internet.

Despite widespread concerns about the dangers of adolescents' online communication with strangers, we know little about (a) which types of adolescents talk with strangers and (b) what motivates them to do so. Drawing on a survey among 412 Dutch adolescents, we found that early adolescents (12-14-year-olds) were most prone to talk with strangers on the internet. If adolescents communicated online more frequently, they less often talked with strangers on the internet. However, if adolescents engaged in long chat sessions, they tended to talk with strangers on the internet more often. In contrast to earlier research, introversion was not related to adolescents' tendency to talk with strangers. The motives of entertainment, meeting new people, and social compensation increased adolescents' online communication with strangers.

Robust estimation of the hierarchical model for responses and response times

Van der Linden's (2007, Psychometrika, 72, 287) hierarchical model for responses and response times in tests has numerous applications in psychological assessment. The success of these applications requires the parameters of the model to have been estimated without bias. The data used for model fitting, however, are often contaminated, for example, by rapid guesses or lapses of attention. This distorts the parameter estimates. In the present paper, a novel estimation approach is proposed that is robust against contamination. The approach consists of two steps. In the first step, the response time model is fitted on the basis of a robust estimate of the covariance matrix. In the second step, the item response model is extended to a mixture model, which allows for a proportion of irregular responses in the data. The parameters of the mixture model are then estimated with a modified marginal maximum likelihood estimator. The modified marginal maximum likelihood estimator downweights responses of test-takers with unusual response time patterns. As a result, the estimator is resistant to several forms of data contamination. The robustness of the approach is investigated in a simulation study. An application of the estimator is demonstrated with real data.     

Technology and Human Becoming

Technology is a mirror that reflects human nature and intentions: (1) we want certain things done and we want tools to do those things; (2) we are finite, frail, and mortal; (3) we create technology in order to bring alternative worlds into being; (4) we do not know why we create or what values should guide us. Imagination is central to technology. Human nature and human freedom are brought into focus when we reflect on the central role of imagination in technology.     

Sexually Explicit Internet Material and Adolescents’ Sexual Performance Orientation: The Mediating Roles of Enjoyment and Perceived Utility

Little is known about how exposure to sexually explicit Internet material (SEIM) relates to a performance-focused orientation toward sex. Based on a three-wave panel study among adolescents (N = 1,022), we found that watching SEIM predicted a sexual performance orientation from Wave (W) 2 to W3, but not from W1 to W2. A sexual performance orientation at W2 predicted adolescents’ exposure to SEIM at W3. The relationship between exposure to SEIM and a sexual performance orientation was explained by a two-step mediation model. The more adolescents were exposed to SEIM at W1, the more they enjoyed consuming this content at W2. In turn, enjoyment of SEIM (W2) predicted adolescents’ perceived utility of SEIM (W2). This increased perceived utility at W2 predicted a more intense performance orientation towards SEIM at W3. Within this 2-step model, we also found full support for a reciprocal relationship between using SEIM (W1/W2/W3) and enjoyment of SEIM (W1/W2/W3) and partial support for a reciprocal relationship between sexual performance orientation (W2) and perceived utility of SEIM (W3).
