Disengaged test taking tends to be most prevalent with low-stakes tests. This has led to questions about the validity of aggregated scores from large-scale international assessments such as PISA and TIMSS, as previous research has found a meaningful correlation between the mean engagement and mean performance of countries. The current study, using data from the computer-based version of the PISA-Based Test for Schools, examined the distortive effects of differential engagement on aggregated school-level scores. The results showed that, although there was considerable differential engagement among schools, the school means were highly stable due to two factors. First, any distortive effects of disengagement in a school were diluted by a high proportion of the students exhibiting no non-effortful behavior. Second, and most interestingly, disengagement produced both positive and negative distortion of individual student scores, which tended to cancel out much of the net distortive effect on the school’s mean.  相似文献

Item content of the Michigan Alcoholism Screening Test (MAST) was modified to make it more appropriate for young persons. The resulting test was found to have lower internal consistency than the adult MAST, but the elimination of five items with comparatively poor psychometric properties yielded an acceptable alpha coefficient of .73. A unitary factor model for the adolescent MAST was not confirmed; indeed, the revised test appeared to be factorially complex. Recommendations for further revisions are discussed.  相似文献

Deciding how to label an object depends both on beliefs about the culturally appropriate name and on memory. A label should be consistent with a language community's norms, but those norms can be used only if they can be retrieved. Two experiments are reported in which we tested the hypothesis that immediate prior exposure to familiar objects and their names affects how an ambiguous target object is named. Exposure to a typical instance of one name category was pitted against exposure to one or two instances from a contrasting category. When the contrast set consisted of a neighbor of the target, naming was usually consistent with the contrast category. This effect was reduced when a typical instance of the contrast category was also exposed. In Experiment 2, the exposure set was varied to include conditions in which either the neighbor or a prototypical instance was paired with an instance dissimilar to the target. The results suggest that all recently exposed objects affect name choice in proportion to their similarity to the target.  相似文献

Cross-correlation and most other longitudinal analyses assume that the association between 2 variables is stationary. Thus, a sample of occasions of measurement is expected to be representative of the association between variables regardless of the time of onset or number of occasions in the sample. The authors propose a method to analyze the association between 2 variables when the assumption of stationarity may not be warranted. The method results in estimates of both the strength of peak association and the time lag when the peak association occurred for a range of starting values of elapsed time from the beginning of an experiment.  相似文献

Three experiments examined the relationship between prejudice and processing of stereotypic information. Higher levels of prejudice were associated with greater attention to and more thorough encoding of stereotype-inconsistent than stereotype-consistent behaviors but only when processing capacity was plentiful (Experiments 1 and 3). High-prejudice participants attributed consistent behaviors to internal factors and inconsistent behaviors to external forces (Experiment 2). Together, these results suggest that high-prejudice people attend carefully to inconsistent behaviors to explain them away but only if they have sufficient resources to do so. Results also showed that low-prejudice but not high-prejudice participants formed individuated impressions by integrating the implications of the target's behaviors (i.e., individuating). High levels of prejudice appear to be associated with biased encoding and judgment processes that may serve to maintain stereotypes.  相似文献

We analyzed previous exploratory factor analytic structures on the Boredom Proneness Scale (BPS; Farmer & Sundberg, 1986) using confirmatory factor analysis in structural equation modeling in LISREL 8 (J?reskog & S?rbom, 1993). These analyses indicated that 2 factors were generally consistent across 6 exploratory models. Items that had significant loadings on these two factors (N = 12; 6 for each factor) indicated a lack of Internal Stimulation and External Stimulation. In further analysis on these 12 items using LISREL, we found a much improved fit and provided support for a short form version of the original BPS. We also found the shortened version to be invariant across gender. We discuss implications for the more precise measurement of boredom proneness and the use of the scale in applied settings.  相似文献

The factor analysis of repeated measures psychiatric data presents interesting challenges for researchers in terms of identifying the latent structure of an assessment instrument. Specifically, repeated measures contain both within and between individual sources of variance. Although a number of techniques exist for separating out these 2 sources of variance, all are problematic. Recently, researchers have proposed that exploratory multilevel factor analysis (MFA) be used to appropriately analyze the latent structure of repeated measures data. The chief objective of this report is to provide a didactic step-by-step guide on how MFA may be applied to psychiatric data. In the discussion, we describe difficulties associated with MFA and consider challenges in factor analyzing life event appraisals in psychiatric samples.  相似文献

Pediatric psychologists use the tools of assessment to evaluate the psychological functioning of youth with chronic and acute medical illnesses. This study is an exploration of the use of a performance-based measure, the Hand Test (HT; Wagner, 1983), with pediatric medical patients. A sample of medical inpatients (n = 27) and psychiatric outpatients (n = 24) were administered the HT, a self-report measure, and a parent-report behavior rating scale. Results indicate that the psychiatric group scored higher than the medical group on HT Aggression, Withdrawal, and Pathological scores. The Aggression (d = 0.90) and Pathological (d = 0.80) variables were particularly robust in differentiating between groups, but the Crippled variable did not differ between groups. Hierarchical logistic regression demonstrated the incremental validity of the HT over behavior ratings alone in the classification of clinical groups. Analyses indicated that the HT can add important information in the differentiation of medically ill children from those with psychological disturbance.  相似文献

For 19 mating-relevant traits, single males (N= 53) and single females (N= 86) rated (a) themselves relative to their same-sex peers, (b) their perceptions of the qualities desired by members of the opposite sex in an ideal partner, and (c) the qualities desired in their own ideal romantic partner. Several themes emerged from the data. First, males’ and females’ judgments of what members of the opposite-sex seek were generally accurate. Second, males and females both feel that they fall short of perceived opposite-sex expectations in a few areas. Third, both males and females desire an ideal partner better than themselves, but this is especially true for females. These findings are discussed in terms of evolutionary social psychological principles.  相似文献
