AbstractDrawing from diverse theoretical frameworks, we examined predictors of discrepancy between current and ideal body image in a sample of 396 Greek adolescents. The participants completed assessments of the frequency of comparing oneself with someone of perceived better appearance, appearance evaluations, frustration of basic psychological needs, and appearance self-compassion. We found that upward appearance comparisons negatively predicted appearance evaluation, which in turn was a negative predictor of body image discrepancy. Moderated mediation analyses showed that appearance self-compassion buffered, whereas psychological need frustration augmented the negative effects of upward comparisons on appearance evaluation. Our findings contribute to the growing literature on body image discrepancies in adolescence by examining moderating factors that amplify or buffer such discrepancies, hence identifying viable intervention pathways. 相似文献

Fake news, deliberately inaccurate and often biased information that is presented as accurate reporting, is perceived as a serious threat. Recent research on fake news has documented a high general susceptibility to the phenomenon and has focused on investigating potential explanatory factors. The present study examined how features of news headlines affected their perceived accuracy. Across four experiments (total N = 659), we examined the effects of pictures, perceptual clarity, and repeated exposure on the perceived accuracy of news headlines. In all experiments, participants received a set of true and false news headlines and rated their accuracy. The presence of pictures and repeated exposure increased perceived accuracy, whereas manipulations of perceptual clarity did not show the predicted effects. The effects of pictures and repeated exposure were similar for true and false headlines. These results demonstrate that accompanying pictures and repeated exposure can affect evaluations of truth of news headlines. 相似文献

Is visual short-term memory object based? Rejection of the "strong-object" hypothesis 总被引:6,自引:0,他引:6
Is the capacity of visual short-term memory (VSTM) limited by the number of objects or by the number of features? VSTM for objects with either one feature or two color features was tested. Results show that capacity was limited primarily by the number of colors to be memorized, not by the number of objects. This result held up with variations in color saturation, blocked or mixed conditions, duration of memory image, and absence or presence of verbal load. However, conjoining features into objects improved VSTM capacity when size-orientation and color-orientation conjunctions were tested. Nevertheless, the number of features still mattered. When feature heterogeneity was controlled, VSTM for conjoined objects was worse than VSTM for objects made of single features. Our results support a weak-object hypothesis of VSTM capacity that suggests that VSTM is limited by both the number of objects and the feature composition of those objects. 相似文献

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence 总被引:1,自引:0,他引:1
This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness. 相似文献

A mailed survey of female prenatal genetic counselors, obstetric nurses, and high school biology teachers was conducted to determine if these groups hold different attitudes toward genetic risk and to investigate the extent to which any differences result from the effect of different professional experiences. In this study, the participants were 166 genetic counselors, 116 obstetric nurses, and 78 biology teachers (n = 360). Survey participants completed a written questionnaire designed to assess their numeric estimate of the empiric risk for birth defects/genetic problems, their subjective perception of this risk, and their personal use of prenatal diagnosis. Genetic counselors were found to be less likely than the other groups to consider the frequency of birth defects/genetic problems as rare and were 10 times more likely than nurses and 8 times more likely than teachers to have had prenatal diagnosis. Furthermore, more than half of the prenatal diagnosis procedures had by genetic counselors were not medically indicated. These results suggest that genetic counselors have an increased perception of genetic risks relative to nurses or teachers. Possible explanations for this finding are discussed, and the potential role of discordant risk perception in creating biases in the genetic counseling process is explored. 相似文献

The ability to remember visual stimuli over a short delay period is limited by the small capacity of visual working memory (VWM). Here the authors investigate the role of learning in enhancing VWM. Participants saw 2 spatial arrays separated by a 1-s interval. The 2 arrays were identical except for 1 location. Participants had to detect the difference. Unknown to the participants, some spatial arrays would repeat once every dozen trials or so for up to 32 repetitions. Spatial VWM performance increased significantly when the same location changed across display repetitions, but not at all when different locations changed from one display repetition to another. The authors suggest that a major role of learning in VWM is to mediate which information gets retained, rather than to directly increase VWM capacity. 相似文献

Concerns have been raised in the literature about the competency to stand trial and competency to make treatment decisions of defendants referred to mental health courts. However, there is little information reported about the evaluation and prevalence of incompetence, characteristics of incompetent mental health court defendants, and disposition of mentally ill defendants too disturbed to be diverted from the criminal justice system through mental health courts. This study reports on the 85 potential mental health court defendants referred for trial competency evaluations during the first three years of operation of the Akron Ohio Mental Health Court. Of the 80 defendants who could be located for evaluation, 77.5% were found incompetent, and 53% of the incompetent defendants were not restored to competence even after an average of 49 days of treatment in a state psychiatric hospital. The implications of these findings in terms of the diversion potential of mental health courts for the severely mentally ill are discussed. 相似文献

The category inclusion rule specifies that categories inherit the properties of their superordinates. For example, given thatall metals are pentavalent, it can be concluded thatall iron is pentavalent. Sloman (1998) showed that people do not fully endorse conclusions that follow from the category inclusion rule. He claims
that people rely on the similarity between the premise and the conclusion categories (metals andiron), rather than applying the category inclusion rule. By allowing reasoners to rate their certainty for category relations
(e.g.,iron is metal), as well as for conclusions, the present study shows that similarity has only an indirect effect on the certainty of conclusions:
Reasoners are more certain that similar categories have a category inclusion relation, and this in turn affects the certainty
of conclusions based on this relation. 相似文献

Parental Discipline and Externalizing Behavior Problems in Early Childhood: The Roles of Moral Regulation and Child Gender 总被引:4,自引:0,他引:4
We tested whether individual differences in a component of early conscience mediated relations between parental discipline and externalizing behavior problems in 238 3.5-year-olds. Parents contributed assessments of discipline practices and child moral regulation. Observations of children's behavioral restraint supplemented parental reports. Parents and teachers reported on child externalizing symptoms. Parental induction, warm responsiveness, and less frequent use of physical punishment generally were associated with higher levels of moral regulation and fewer externalizing problems. Moreover, moral regulation partially mediated relationships between discipline and externalizing symptoms, with the clearest case of mediation involving induction. However, relationships were found for boys only. Results support a mediation model wherein inductive and physical discipline may influence the expression of boys' externalizing behavior through effects on conscience. Finally, results suggest that different developmental processes may be associated with early externalizing problems in boys and girls, and confirm that fathers' reports contribute to our understanding of the origins of child externalizing problems. 相似文献
