Little is known about the effects of playing sexualizing video games on adolescent boys’ and girls’ self-objectified body image. Early and middle adolescents (N = 115; Mage = 12.63, SD = 0.85) participated in a between-subjects experiment testing the effect of playing with a sexualized male or female avatar as compared to a control condition. We revealed that playing a video game with a sexualized avatar increased self-objectification among adolescents. This effect occurred regardless of the gender of the adolescent and, thus, did not support the gender congruency hypothesis. In contrast to the activation frequency hypothesis and video game literature on sexualization, the effect of playing with a female sexualized avatar was not moderated by game frequency. Given the adverse consequences of self-objectification in adolescence, the current study results highlight the need for research on how these effects may be countered.  相似文献

Whether having children improves our well-being is a long-standing topic of debate. Demographic and sociological research has investigated changes in individuals’ overall well-being and partnership satisfaction when they become parents. However, little is known about how becoming parent may produce vulnerability—observable as an enduring decrease in well-being—in life domains that are strongly interdependent with the family domain, such as work and leisure. Linking life-course and personality psychology perspectives, the authors examine the trajectories of subjective well-being—measured as satisfaction with life, work, and leisure—3 years before and 3 years after the transition to parenthood. The authors particularly focus on the moderating effects of gender and personality. Using data from the German Socio-Economic Panel (1984–2013) and multilevel growth curve modeling, the authors show strong gender-based vulnerability in how people react to parenthood. Although men display a nonlinear pathway of decreasing life satisfaction and a stable trajectory of job satisfaction, women experience more changes in their satisfaction with work and more dramatic decreases in leisure satisfaction. Contrary to most of our expectations, the moderating effects of personality were modest. Extraversion influenced the trajectories of work satisfaction, whereas neuroticism and conscientiousness affected the pathway of leisure satisfaction for women only. This article shows that the transition to parenthood influences well-being trajectories in specific domains, and this influence differs between women and men.  相似文献

This study examines how semi-elite student snow-sport athletes utilize process and trait coping strategies to combat risk-taking, potential loss and trauma, and other stressors integral to their sport participation. Factors influencing coping strategy preference are also explored. Semistructured interviews were used to explore 10 participants’ experiences; the narratives were analyzed using thematic analysis. Five master themes emerged from the analysis: Challenges to Overcome; Taking Action; Changing Perspectives; Staying in Control; and Underlying Influences. The findings highlight how participants develop and utilize preferred coping strategies, although the unpredictable nature of snow-sports can result in situation-specific process coping. Findings are discussed in relation to the differences between racing and freestyle disciplines.  相似文献

In this study, we assessed to what extent reasoning improves performance in decision making under risk in a laboratory gambling task (Game of Dice Task-Double, GDT-D). We also investigated to what degree individuals with above average mathematical competence decide better than those with average mathematical competence. Eighty-five participants performed the GDT-D and several numerical tasks. Forty-two individuals were asked to calculate the probabilities and the outcomes associated with the different options of the GDT-D before performing it. The other 43 individuals performed the GDT-D at the beginning of the test session. Both reasoning and mathematical competence had a positive effect on decision making. Different measures of mathematical competence correlated with advantageous performance in decision making. Results suggest that decision making under explicit risk conditions improves when individuals are encouraged to reflect about the contingencies of a decision situation. Interventions based on numerical reasoning may also be useful for patients with difficulties in decision making.  相似文献

This article investigates whether acts of plagiarism are predictable. Through a deductive, quantitative method, this study examines 517 students and their motivation and intention to plagiarize. More specifically, this study uses an ethical theoretical framework called the Theory of Reasoned Action (TORA) and Planned Behavior (TPB) to proffer five hypotheses about cognitive, relational, and social processing relevant to ethical decision making. Data results indicate that although most respondents reported that plagiarism was wrong, students with strong intentions to plagiarize had a more positive attitude toward plagiarizing, believed that it was important that family and friends think plagiarizing is acceptable, and perceived that plagiarizing would be an easy task. However, participants in the current study with less intention to plagiarize hold negative views about plagiarism, do not believe that plagiarism is acceptable to family, friends or peers, and perceive that the act of plagiarizing would prove difficult. Based on these findings, this study considers implications important for faculty, librarians, and student support staff in preventing plagiarism through collaborations and outreach programming.  相似文献

The bisection of lines positioned radially (with the two ends of the line close and far, with respect to the participant's body) has been less investigated than that of lines placed horizontally (with their two ends left and right, with respect to the body's midsagittal plane). In horizontal bisection, patients with left neglect typically show a rightward bias for both lines and words, greater with longer stimuli. As for radial bisection, available data indicate that neurologically unimpaired participants make a distal error, while results from right‐brain‐damaged patients with left spatial neglect are contradictory. We investigated the bisection of radially oriented words, with the prediction that, during bisection, linguistic material would be recoded to its canonical left‐to‐right format in reading, with the performance of neglect patients being similar to that for horizontal words. Thirteen right‐brain‐damaged patients (seven with left spatial neglect) and fourteen healthy controls were asked to manually bisect 40 radial and 40 horizontal words (5–10 letters), and 80 lines, 40 radial and 40 horizontal, of comparable length. Right‐brain‐damaged patients with spatial neglect exhibited a proximal bias in the bisection of short radial words, with the proximal part corresponding to the final right part of horizontally oriented words. This proximal error was not found in patients without neglect and healthy controls. For bisection, short radial words may be recoded to the canonical orthographic horizontal format, unveiling the impact of left neglect on radially oriented stimuli.  相似文献

There is abundant evidence that there is a performance cost associated with switching between tasks. This “switch cost” has been postulated to be driven by task performance on the preceding trial, but recent research challenges any necessary role of previous task performance in driving the cost. Across three experiments, we investigated whether it is difficult to switch from a task that was prepared but never performed. We replicated the finding of a switch cost following cue-only trials (involving no task performance) whilst controlling for a potential cue-switching confound. This cost was larger than that following completed trials when preparation interval was short (300?ms), and it reduced significantly with a longer preparation interval (1000?ms) on the current trial. We also found that preparing only to attend to a particular visual dimension (colour or shape) was sufficient to drive a significant subsequent switch cost, which appeared to be residual in nature; we speculate that this cost may reflect the persistence of unfulfilled task intentions and/or a strategic slowing when consecutive intentions conflict.  相似文献

From the perspective of signal detection theory, different lineup instructions may induce different levels of response bias. If so, then collecting correct and false identification rates across different instructional conditions will trace out the receiver operating characteristic (ROC)—the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of a mock crime, participants were presented with instructions followed by a six‐person simultaneous photo lineup. The ROCs from both methods were similar, but they were not exactly the same. These findings have potentially important policy implications for how the legal system should go about controlling eyewitness response bias.Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

This study investigates the test–retest reliability of a battery of executive function (EF) tasks with a specific interest in testing whether the method that is used to create a battery-wide score would result in differences in the apparent test–retest reliability of children’s performance. A total of 188 4-year-olds completed a battery of computerized EF tasks twice across a period of approximately two weeks. Two different approaches were used to create a score that indexed children’s overall performance on the battery—i.e., (1) the mean score of all completed tasks and (2) a factor score estimate which used confirmatory factor analysis (CFA). Pearson and intra-class correlations were used to investigate the test–retest reliability of individual EF tasks, as well as an overall battery score. Consistent with previous studies, the test–retest reliability of individual tasks was modest (rs ≈ .60). The test–retest reliability of the overall battery scores differed depending on the scoring approach (rmean = .72; rfactor_score = .99). It is concluded that the children’s performance on individual EF tasks exhibit modest levels of test–retest reliability. This underscores the importance of administering multiple tasks and aggregating performance across these tasks in order to improve precision of measurement. However, the specific strategy that is used has a large impact on the apparent test–retest reliability of the overall score. These results replicate our earlier findings and provide additional cautionary evidence against the routine use of factor analytic approaches for representing individual performance across a battery of EF tasks.  相似文献

Our purpose in this systematic review was to identify, evaluate, and summarize the single-case research design studies examining behavioral interventions to address self-injurious behavior for young children with autism spectrum disorder. We identified 24 studies published between 2000 and 2016 that met the inclusion criteria. We reviewed and coded each study across five content areas using systematic procedures. These content areas consisted of the methodological quality of single-case research designs, children’s demographic information, conditions under which the intervention was implemented, characteristics of intervention, and outcomes. Our findings indicate that procedural integrity data were reported for only one study and social validity for two studies. The majority of studies were implemented by researchers or therapists in the school setting. For 24 of 30 children included in the studies reviewed, the authors taught a replacement behavior selected on the basis of an assessment conducted prior to intervention. All authors reported a decrease in the self-injurious behavior post-intervention. A limited number of authors examined generalization and maintenance of low rates of self-injurious behavior. Limitations of the present review and future directions and implications for research and practice are discussed.  相似文献
