Relative outcomes in social commerce with peers are potent determinants of cognitions and behavior in young children. Although there has been considerable attention given to the behavioral consequences of social comparisons following the receipt of rewards, there has been less concern with cognitive or affective consequences. Additionally, little is known about the accrued effects of multiple social comparison experiences that may be consistent or inconsistent with one another. In the present study, young children received a constant level of reward but the amount they saw a peer receive was varied. There were two sequences of reward distribution, and in a given sequence children received either the same number of rewards as the peer (=), more (+), or fewer (?). In a 3 × 3 factorial design all possible combinations occurred. A negative inequality in reward distribution, no matter where it fell in a sequence, made children sad and inclined children to distribute fewer rewards to peers. When a sequence contained an initial experience of positive inequality, children decreased subsequent levels of self-reward. Experiencing a comparison that revealed a negative inequality in reward distribution also disrupted children's accuracy in appraising the overall distribution of rewards: even when an initial negative inequality was completely offset by an equivalent experience of positive inequality, children inaccurately concluded that they had received fewer rewards than their peers.  相似文献

The Depressive Experiences Questionnaire: revision and validation   总被引:3,自引:0,他引:3  
The present study presents a new, unit-weight scoring system for the Depressive Experiences Questionnaire (DEQ). One hundred thirty-one college students completed the DEQ, the Bem Sex-Role Inventory (BSRI), and the Beck Depression Inventory (BDI). The revised DEQ scales were shown to have substantial levels of internal consistency. The three subscales of the revised DEQ were significantly correlated with the BSRI masculinity and femininity scales but not with gender. Significant correlations were also obtained between DEQ anaclitic, DEQ introjective scales and the BDI.  相似文献

Understanding multiple personality with the Comprehensive Rorschach system   总被引:1,自引:0,他引:1  
Exner's Comprehensive Rorschach system is utilized in studying a unique sample of patients--three multiple personalities. Each patient and a number of secondary personalities are tested. Several interpretative and technical aspects of Exner's system are clarified. All of the main personalities are ambient, extending Exner's conclusions regarding the implications of this style. The secondary personalities have personality structures which are remarkably different from those of the main personalities. Differences from previous studies are attributed to unique administrative features of the Comprehensive system.  相似文献

The influence of perceived somatotype on stereotypes of behavior associated with body build was investigated among 160 male and 140 female Nigerian children in secondary school. In both groups, the perception of subjects' own physiques and discrepancy between their perceived and preferred physiques significantly explained the variance in the character trait scores attributed to body types. In general, the subjects attributed positive character traits to their perceived somatotypes and undesirable traits to the physiques with which they were dissatisfied. Thus, the perception of somatotype and discrepancy between perceived and preferred physique could significantly differentiate the character traits attributed to body build among male and female children.  相似文献

Many counselors are currently undergoing a Kuhnian paradigm shift from linear models of behavioral problem conceptualization to systemic conceptual models. As a result, it has become incumbent on counselor-educators to introduce the systems concept of family therapy to their students within a framework that renders it meaningful not only intellectually but also practically. This paper presents one way of doing this successfully with master's level counselors-in-training who have no live families on which to practice. An overview of systems approaches to family therapy is presented along with a seven-stage supervision approach for teaching structural/strategic therapy in limited situations where the supervision of live families is not practical or possible.  相似文献

Test-retest stability of the Kaufman Assessment Battery for Children (K-ABC) was investigated over a 512-month interval for 42 Mexican-American preschool/kindergarten children. The results indicated that the stability coefficients for K-ABC Global scales and subtests were generally of adequate magnitudes (e.g., .70s and .80s), providing some evidence that the K-ABC is a relatively stable instrument for the sample. The results are discussed in the context of a test-retest study reported in the K-ABC Manual. Global scale stability coefficients were found to range from .76 to .90, and for the subtests the coefficients ranged from .26 to .89. The patterns of gain scores were very similar to the patterns reported in the stability investigation in the K-ABC Manual.  相似文献

Practitioners are frequently faced with the need to evaluate the intellectual skills of individuals with very low levels of functioning. Owing to the statistical rarity of these persons, few tests have sufficient range of scores for a detailed analysis of intraindividual differences in performance. This paper describes a method that uses are equivalents and standard scores to recreate the full range of variability in the scores of low-functioning individuals. The method allows for a more complete interpretation of performance that can lead to better educational and therapeutic programming.  相似文献
