To facilitate understanding of the factors associated with child depressive symptoms in middle childhood, we examined the roles of parental support for autonomy and parent–child attachment in child depressive symptoms among 150 Chinese parent–child dyads. The participating children’s ages ranged from 6 to 12 years old. Parental support for autonomy was coded from a conflict resolution and a cooperation task. Children reported their depressive symptoms and their attachment relationships with the participating parents. After controlling for parent depressive symptoms, parental support for autonomy was associated with fewer child depressive symptoms. The association between parental support for autonomy and child depressive symptoms was mediated by parent–child attachment quality, suggesting that parental support for autonomy was negatively associated with child depressive symptoms through its positive association with parent–child attachment quality. Moreover, the positive association between parental support for autonomy and parent–child attachment quality was stronger for older children. The current study expanded the knowledge on parental support for autonomy in middle-childhood and its association with parent–child relationships and child mental health. Future research is encouraged to pay more attention to the role of parental support for autonomy in various aspects of child development for children in middle-childhood and pre-adolescence. 相似文献

This article proposes an integrative framework for understanding the accuracy and inaccuracy of stereotypes. Specifically, we highlight research issues and traditions from social and personality psychology that do not often intersect, but which can be mutually informative. Within this framework, the social psychologist's interest in the accuracy of group stereotypes is conceptually much like a personality psychologist's interest in the accuracy with which perceivers can identify types of individuals, for example extraverts. Both fields make use, implicitly or explicitly, of personal attributes and behaviors (cues) in assessing accuracy of beliefs about group or individual traits. By using Brunswik's lens model perspective in combination with concepts from signal detection theory, judgments of stereotypes can be discovered to be accurate or inaccurate depending on how perceivers judge or use the cues. In drawing on research traditions and theoretical frameworks from both social and personality psychology, researchers can go beyond an all‐or‐nothing stance regarding stereotype accuracy to achieve a more nuanced understanding of when, how, and to what extent stereotypes are accurate. 相似文献

This study examined correlates of academic procrastination and students’ grade goals in a sample of 226 undergraduates from
Singapore. Findings indicated that self-efficacy for self-regulated learning was significantly and negatively related to procrastination.
High self-efficacy for self-regulated learning also predicted students’ expectations of doing well and low self-efficacy for
self-regulated learning predicted students’ expectations of not doing well academically. Additionally, help-seeking predicted
students’ expectations of doing well academically while academic stress predicted students’ expectations of not doing well
academically. Implications for education and educational practice were discussed.

The present study predicts cigarette and alcohol use in adolescence from the development of children's cognitions in the elementary years. Using latent growth modeling, the authors examined a model using data from 712 participants in the Oregon Youth Substance Use Project, who were in the 2nd through 5th grade at the 1st assessment and followed for 6 annual or semiannual assessments over 7 years. Growth in children's prototypes and subjective norms in the elementary years (Times 1 through 4) were related to their substance use in adolescence (Time 6) through their willingness and intentions (Time 5) to smoke and drink. Across the sample, for both substances, the intercept and slope of prototypes were either indirectly related to use through willingness or directly related to use. Both the intercept and slope of subjective norms were indirectly related to use of both substances through both willingness and intentions and directly related to cigarette use. Results suggest that elementary children have measurable cognitions regarding substance use that develop during the elementary years and predict use later in adolescence. These findings emphasize the need for prevention programs targeted at changing children's social images of substance users and encouraging more accurate perceptions of peers' use. 相似文献

Corticotrophin-releasing hormone (CRH) plays a pivotal role in the suppression of the gonadotrophin-releasing hormone (GRH) pulse generator in response to stress and intracerebroventricular (i.c.v.) administration of calcitonin gene-related peptide (CGRP). We have previously shown both CRH receptor subtypes, CRH-R1 and CRH-R2, are involved in the stress-induced suppression of LH pulses. The aims of the present study were to examine the role of CRH-R1 and CRH-R2 in CGRP-induced suppression of LH pulses, and to investigate the effects of CGRP on CRH expression in the paraventricular nucleus (PVN) and central nucleus of the amygdala (CeA), which have prominent CRH neurone populations that receive dense CGRP innervations. The suppression of LH pulses by CGRP (1.5 microg i.c.v.) was completely prevented by intravenous administration of the CRH-R1 antagonist SSR125543Q (7.5 mg/rat i.v., 30 min before CGRP), but was not affected by the CRH-R2 antagonist, astressin(2)-B (100 microg i.c.v., 10 min before CGRP). CGRP increased the CRH mRNA expression in PVN and CeA. These results provide evidence of a role for CRH-R1 in mediating the suppressive effects of CGRP on pulsatile LH secretion in the female rat, and additionally raise the possibility of an involvement of PVN and CeA CRH neuronal populations in this suppression. 相似文献

Adapting decision making according to dynamic and probabilistic changes in action-reward contingencies is critical for survival in a competitive and resource-limited world. Much research has focused on elucidating the neural systems and computations that underlie how the brain identifies whether the consequences of actions are relatively good or bad. In contrast, less empirical research has focused on the mechanisms by which reinforcements might be used to guide decision making. Here, I review recent studies in which an attempt to bridge this gap has been made by characterizing how humans use reward information to guide and optimize decision making. Regions that have been implicated in reinforcement processing, including the striatum, orbitofrontal cortex, and anterior cingulate, also seem to mediate how reinforcements are used to adjust subsequent decision making. This research provides insights into why the brain devotes resources to evaluating reinforcements and suggests a direction for future research, from studying the mechanisms of reinforcement processing to studying the mechanisms of reinforcement learning. 相似文献

The prospective effects of observed neighborhood disorder, stressful life events, and parents’ engagement in inductive reasoning
on adolescents’ depressive symptoms were examined using data collected from 777 African American families. Multilevel analyses
revealed that stressful life events experienced at age 11 predicted depressive symptoms at age 13. Furthermore, a significant
interaction between neighborhood disorder and parents’ engagement in inductive reasoning was found, indicating that parental
use of inductive reasoning was a protective factor for depressive symptoms particularly for youths living in highly disordered
neighborhoods. The importance of examining correlates of depressive symptoms from a contextual framework, focusing on individuals,
families, and neighborhood contexts, is emphasized. 相似文献

Various researchers have suggested that certain anthropometric ratios can be used to measure female body attractiveness, including the waist to hip ratio, Body Mass Index (BMI), and the body volume divided by the square of the height (Volume-Height Index). Based on a wide range of female subjects and virtual images of bodies with different ratios, Volume-Height Index was found to provide the best fit with female body attractiveness, and the effect of Volume-Height Index can be fitted with two half bell-shaped exponential curves with an optimal Volume-Height Index at 14.2 liter/m2. It is suggested that the general trend of the effect of Volume-Height Index may be culturally invariant, but the optimal value of Volume-Height Index may vary from culture to culture. In addition to Volume-Height Index, other body parameters or ratios which reflect body proportions and the traits of feminine characteristics had smaller but significant effects on female body attractiveness, and such effects were stronger at optimum Volume-Height Index. 相似文献

Meta-analysis of the relationship between risk perception and health behavior: the example of vaccination. 总被引:1,自引:0,他引:1

BACKGROUND: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. METHOD: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. RESULTS: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. CONCLUSIONS: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior. 相似文献
