Ecological validity of neuropsychological assessment includes the ability of tests to predict real-world functioning and/or covary with brain structures. Studies have examined the relationship between adaptive skills and test performance, with less focus on the association between regional brain volumes and neurobehavioral function in healthy children. The present study examined the relationship between temporal lobe gray matter volumes and performance on two neuropsychological tests hypothesized to measure temporal lobe functioning (visual perception-VP; peabody picture vocabulary test, third edition-PPVT-III) in 48 healthy children ages 5-18 years. After controlling for age and gender, left and right temporal and left occipital volumes were significant predictors of VP. Left and right frontal and temporal volumes were significant predictors of PPVT-III. Temporal volume emerged as the strongest lobar correlate with both tests. These results provide convergent and discriminant validity supporting VP as a measure of the "what" system; but suggest the PPVT-III as a complex measure of receptive vocabulary, potentially involving executive function demands. 相似文献

The present research was conducted to clarify the relationships among social anxiety, alcohol consumption, alcohol-related problems, and negative-reinforcement drinking motives among college students. Heavy drinking students (N = 316, 53.80% female) completed self-report measures of social anxiety, alcohol consumption, alcohol-related problems, and drinking motives. Findings indicated that students higher in social anxiety consumed less alcohol but experienced more negative consequences. Moreover, the relationship between social anxiety and negative consequences was mediated by coping and conformity drinking motives in addition to alcohol consumption. In the context of social anxiety, the current research demonstrates the importance of examining problematic drinking as distinct constructs: alcohol consumption and negative consequences. Findings are also discussed in terms of implications for interventions with socially anxious students. 相似文献

This study examined longitudinal associations between parents' hostility and siblings' externalizing behavior in the context of interparental discord. The sample included 116 families (mothers, fathers, 2 siblings) assessed in middle childhood, when siblings were, on average, 8 and 10 years old, and in adolescence, at average ages of 14 and 16 years. Parents reported on their hostility toward each child and on each child's externalizing problems. Raters observed interparental hostility, and parents rated their marital quality. Results indicated both within-family and between-families effects. Specifically, the child who received more parental hostility than his or her sibling showed greater increases in externalizing problems than his or her sibling; this association was moderated by marital discord. In addition, the child who exhibited more behavioral problems than his or her sibling received greater increases in hostile mothering than did his or her sibling. Between-families effects were evident, in that children's externalizing problems were associated with increases in mothers' hostility toward both children in the family. Results support transactional models of development and family systems theory. 相似文献

Age-related change in the difference between left- and right-side speed on motor examination may be an important indicator of maturation. Cortical maturation and myelination of the corpus callosum are considered to be related to increased bilateral skill and speed on timed motor tasks. We compared left minus right foot, hand, and finger speed differences using the Revised Physical and Neurological Assessment for Subtle Signs (PANESS; Denckla, 1985); examining 130 typically developing right-handed children (65 boys, 65 girls) ages 7-14. Timed tasks included right and left sets of 20 toe taps, 10 toe-heel alternation sequences, 20 hand pats, 10 hand pronate-supinate sets, 20 finger taps, and 5 sequences of each finger-to-thumb apposition. For each individual, six difference scores between left- and right-sided speeded performances of timed motor tasks were analyzed. Left-right differences decreased significantly with age on toe tapping, heel-toe alternations, hand pronation-supination, finger repetition, and finger sequencing. There were significant gender effects for heel-toe sequences (boys showing a greater left-right difference than girls), and a significant interaction between age and gender for hand pronation-supination, such that the magnitude of the left-right difference was similar for younger, compared with older girls, while the difference was significantly larger for younger, compared to older boys. Speed of performing right and left timed motor tasks equalizes with development; for some tasks, the equalization occurs earlier in girls than in boys. 相似文献

Two studies investigated the connection between narcissism and sensitivity to criticism. In study 1, participants completed
the Narcissistic Personality Inventory (NPI) and the Sensitivity to Criticism Scale (SCS) and were asked to construct and
deliver speeches to be rated by performance judges. They were then asked whether they would like to receive evaluative feedback.
Narcissism and sensitivity to criticism were mildly, but not significantly, negatively correlated and had contrasting relationships
with choices regarding feedback. Highly narcissistic participants tended to seek (rather than avoid) feedback, whereas highly
sensitive participants tended to reject feedback opportunities. Study 2 examined the relationship between sensitivity to criticism
and both overt and covert narcissism. Those scoring high on the trait narcissism, as measured by the NPI, tended to be less
sensitive to criticism, sought (rather than avoided) feedback opportunities, experienced little internalized negative emotions
in response to “extreme” feedback conditions, and did not expect to ruminate over their performance. By contrast, participants
scoring high on a measure of “covert narcissism” were high in sensitivity to criticism, tended to avoid feedback opportunities,
experienced high levels of internalized negative emotions, and showed high levels of expected rumination. These findings suggest
that the relationship between narcissism and sensitivity to criticism is highly dependent upon the definition or “form” of
narcissism considered. 相似文献

Previous research demonstrates that implicitly learned probability information can guide visual attention. We examined whether the probability of an object changing can be implicitly learned and then used to improve change detection performance. In a series of six experiments, participants completed 120–130 training change detection trials. In four of the experiments the object that changed color was the same shape (trained shape) on every trial. Participants were not explicitly aware of this change probability manipulation and change detection performance was not improved for the trained shape versus untrained shapes. In two of the experiments, the object that changed color was always in the same general location (trained location). Although participants were not explicitly aware of the change probability, implicit knowledge of it did improve change detection performance in the trained location. These results indicate that improved change detection performance through implicitly learned change probability occurs for location but not shape. 相似文献

Economic disadvantage is associated with multiple risks to early socioemotional development. This article reviews research regarding family stress frameworks to model the pathways from economic disadvantage to negative child outcomes via family processes. Future research in this area should expand definitions of family and household to incorporate diversity and instability. This expansion would be particularly relevant for research among low-income ethnic minority families and families with young children. This line of research would highlight specific pathways to target to prevent the onset of early parental and child dysfunction. 相似文献

Topographically similar verbal responses may be functionally independent forms of operant behavior. For example, saying yes or no may have different functions based on the environmental conditions in effect. The present study extends previous research on both the assessment and acquisition of yes and no responses across contexts in children with language deficits and further examined the functional independence of topographically similar responses. All participants in the present study acquired yes and no responses within verbal operants (e.g., mands). However, generalization of the responses across novel verbal operants (e.g., tacts to intraverbals) did not occur without additional training, thus supporting Skinner's (1957) assertion of functional independence of verbal operants. 相似文献

Considerable research has examined how procedural injustice affects victims and witnesses of unfavorable outcomes, with little attention to the “performers” who deliver these outcomes. Drawing on dissonance theory, we hypothesized that performers' reactions to procedural injustice in delivering unfavorable outcomes are moderated by prosocial identity—a helping‐focused self‐concept. Across 2 experiments, individuals communicated unfavorable outcomes decided by a superior. Consistent with justice research, when prosocial identities were not primed, performers experienced greater negative affect and behaved more prosocially toward victims when a superior's decision‐making procedures were unjust. Subtly activating performers' prosocial identities reversed these reactions. Results highlight how roles and identities shape the experience and delivery of unfavorable outcomes: When procedures are unjust, prosocial identity can reduce prosocial behavior. 相似文献

The Beck Self-Concept Inventory for Youth (BYI-S; Beck et al. in Manual for the Beck Youth Inventories of Emotional and Social
Impairment, 2001) was administered to 100 adolescents (12–17 years old) who experienced sexual abuse. An iterated principal-factor analysis
found that the BYI-S represented two highly correlated (r = .53) factors corresponding to the Self-Esteem and Competency dimensions that Steer, Kumar, Beck, and Beck (J Psychopathol Behav Assess 27:123–131, 2005) found with child psychiatric outpatients. Item analyses were used to derive two six-item subscales measuring Self-Esteem
and Competency that had coefficient αs > .80. The Self-Concept total and subscale scores were differentially correlated with various psychosocial characteristics
of the youth. Low Self-Esteem scores were associated with total number of posttraumatic symptoms and self-reported anger,
whereas low Competency scores were related to externalizing behavior problems. The BYI-S was discussed as being a useful instrument
for assessing the self-concepts of youth who have experienced sexual abuse. 相似文献
