When observers localize the vanishing point of a moving target, localizations are reliably displaced beyond the final position, in the direction the stimulus was travelling just prior to its offset. We examined modulations of this phenomenon through eye movements and action control over the vanishing point. In Experiment 1 with pursuit eye movements, localization errors were in movement direction, but less pronounced when the vanishing point was self‐determined by a key press of the observer. In contrast, in Experiment 2 with fixation instruction, localization errors were opposite movement direction and independent from action control. This pattern of results points at the role of eye movements, which were gathered in Experiment 3. That experiment showed that the eyes lagged behind the target at the point in time, when it vanished from the screen, but that the eyes continued to drift on the targets' virtual trajectory. It is suggested that the perceived target position resulted from the spatial lag of the eyes and of the persisting retinal image during the drift. 相似文献

Tests of personality, interests, intelligence, and academic achievement were administered by 271 Ss. The data were processed by the principal component method of factor analysis. Twelve second-order factors were extracted and interpreted after oblique maxplane rotation. 相似文献

Prior research suggests that perceived performance of a product or a service is directly linked to postpurchase satisfaction. We argue that this causal relationship might be a measurement artifact and/or insufficient modeling of the satisfaction process rather than an accurate assessment of how consumers form satisfaction judgments. To test our hypotheses, a 2 x 2 x 2 (Performance x Expectations x Needs) factorial design was used with 2 types of perceived performance measures (value-laden and objective). The findings demonstrate that the observed direct link from perceived performance to overall satisfaction diminishes when more objective perceived performance indicators replace the commonly used value-laden measures. Furthermore, desire-congruency was found to contribute independently to satisfaction over and above a disconfirmation-of-expectations standard. In fact, desire-congruency was found to be a better predictor of satisfaction than disconfirmation-of-expectations. Finally, our results suggest that the direct performance–satisfaction link becomes insignificant when the modeling of the satisfaction process is improved. Taken together, these findings support the view that the frequently observed high correlations between perceived performance and satisfaction might be a reflection of the type of measures used and/or insufficient capturing of the evaluative process leading to satisfaction, rather than support for a direct causal link. 相似文献

The present studies examine how perceived temporal distance from past selves influences perceptions of the current self. Participants recalled their past self either at age 9 or 15. These two past selves differ in levels of identification with gender and thus denote different standards of comparison. Three hypotheses were tested. Temporal distance should determine whether recalled past selves produce assimilation or contrast effects on the current self. Second, temporal comparison effects should be weaker when people recall their past in terms of stable, relatively enduring characteristics (e.g. traits). Third, past selves should to a greater extent be biased by stereotypical knowledge about former lifetime periods the farther away individuals feel from past selves. Past selves coloured by stereotypical knowledge are more extreme and should thus produce stronger judgemental effects on the current self. The results supported the hypotheses. Implications for autobiographical remembering are discussed. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Previous research has been largely silent about what precisely influences online friendship formation and has ignored motives for online communication as potential explanations. Drawing on a sample of 493 adolescents, this study tested a path model of adolescent friendship formation including as predictors introversion/extraversion, online self-disclosure, motive for social compensation, and frequency of online communication. Our path analysis showed that extraverted adolescents self-disclosed and communicated online more frequently, which, in turn, facilitated the formation of online friendships. Introverted adolescents, by contrast, were more strongly motivated to communicate online to compensate for lacking social skills. This increased their chances of making friends online. Among introverted adolescents, a stronger motive for social compensation also led to more frequent online communication and online self-disclosure, resulting in more online friendships. The model suggests that the antecedents of online friendship formation are more complex than previously assumed and that motives for online communication should be studied more closely. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
