In this study, we examined the role that materialism plays in the family structure–stress relation in a sample of adolescents. Materialism is a complex construct that appears to both mediate and moderate the family structure–stress relation as well as have both positive and negative effects. The happiness dimension of materialism in particular appears to both mediate and moderate the family structure–stress relation. Adolescents who associate happiness with material possessions report higher levels of family stress due to family disruption (parental divorce) compared with those who are less likely to associate happiness with material possessions. This finding runs contrary to recent marketing research. Additionally, we found the success dimension of materialism to have a direct and salubrious impact on family stress levels. 相似文献

Few studies have examined the impact of violent victimization on friendship networks. This study used 2 waves of data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the effects of violent victimization on number of peer- and self-reported friendships. Guided by stigma theory (Goffman, 1963), fixed-effect regression models controlling for depression, delinquency, substance use, and school engagement were completed to predict changes in number of friends following victimization. Consistent with the theory, results indicate that experiencing violent victimization (e.g., jumped, stabbed, shot at) was associated with a decrease in number of friends. These effects were magnified for females and for individuals with a greater number of depressive symptoms. These results were consistent even when models were run separately for each individual type of victimization. Treatment and prevention implications are discussed. 相似文献

Change detection performance is influenced by a number of factors, among which is the informativeness of targets. It has not
been clarified, yet, whether the highly informative regions have a processing priority as a result of resource deployment
from other tasks or whether it results from a better resource management. In this paper, we adopted a change detection paradigm
in which thirty participants were randomly assigned to two groups: single (change detection task) and dual task [change detection
and a simplified version of the Paced Auditory Serial Oppository Task (PASOT, Gow and Deary in J Clin Exp Neuropsychol 26:723–736,
2004), which implies a verbal effort]. Stimulus informativeness was defined as social relevance, that is, changing targets were
people (high relevance) versus objects (low relevance), all other aspects (i.e., salience and position in the scene) kept
constant. As hypothesized, data analyses showed a significant main effect of social relevance and task condition, i.e., better
change detection performance and lower change detection times for people versus objects and for single than for dual task
condition. Interestingly, the PASOT accuracy remained stable across the person versus object trials, thus implying that the
better performance with socially relevant targets could not be explained by a resources withdrawal from the secondary task.

We examine how the presence of children is related to women’s and men’s productivity. We hypothesize family demands, family resources, and family-friendly workplaces are also related to productivity. Productivity for 670 Alberta law firm lawyers is analyzed using a standardized measure of productivity referred to as billable hours. The results suggest that mothers with school-aged children are less productive than non-mothers, whereas fathers with preschool-aged children are more productive than non-fathers. While time spent on household and childcare tasks significantly reduces women’s productivity, we find little support for the benefits of family resources or working in a family-friendly firm for women. Rather, fathers seem to benefit more: family resources are positively related to their productivity and family-friendly benefits allow them more time for leisure. These results support the assumption that having children is negatively related to women’s productivity but challenges the belief that family-friendly policies are primarily beneficial only to mothers trying to balancing work and family. 相似文献

The purpose of the study was to examine the effectiveness of the micro‐expressions training tool (METT) in identifying and using micro‐expressions to improve lie detection. Participants (n = 90) were randomly assigned to receive training in micro‐expressions recognition, a bogus control training, or no training. All participants made veracity judgements of five randomly selected videos of targets providing deceptive or truthful statements. With the use of the Bayesian analyses, we found that the METT group did not outperform those in the bogus training and no training groups. Further, overall accuracy was slightly below chance. Implications of these results are discussed. 相似文献

Extending previous work on biased predecisional processing, we investigate the distortion of information during the evaluation of a single option. A coherence-based account of the evaluation task suggests that individuals will form an initial assessment of favorability toward the option and then bias their evaluation of subsequent information to cohere with their initial disposition. Three experiments tested this hypothesis. Initial disposition was manipulated (Studies 1 and 3) or measured (Study 2), and attribute ratings were collected as indicators of information distortion. Results from all three experiments indicate that attribute evaluations were biased to favor initial dispositions. These findings provide evidence that information distortion is one cause of primacy effects in judgment and decision-making settings involving a single option. 相似文献

When Are Tutorial Dialogues More Effective Than Reading? 总被引:2,自引:0,他引:2
It is often assumed that engaging in a one-on-one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5-step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural-language-based computer tutoring (Why2-Atlas and Why2-AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text-based control conditions. 相似文献
