A new approach to testing for and training in spatial aptitude is described. Figurai analogy problem terms from the cognitive abilities test are photodigitized and arrayed in zones on the computer screen; they can be seen only when selected with the mouse (i.e., one at a time). Viewing patterns and durations can then be analyzed to assess problem encoding and solution strategies. Implications are discussed. 相似文献

In a concurrent validity study, a comprehensive job analysis of a mid-level secretarial position resulted in the development of highly valid employment selection instruments. Six hundred fifty-nine supervisors and 883 incumbents in 20 locations participated in the job analysis. Scores from the selection test correlated with composite ratings from a research performance appraisal (RPA) .41 (p<.001). Two forms of the test (A and B) were developed. Form A and Form B test scores and RPA composite ratings correlated .55 and .48 (p<.001) respectively. The unbiased estimate of equivalence reliability of Form A and Form B was .94. The two tests correlated .89 (p<.001). 相似文献

The effectiveness of Classwide Peer Tutoring (CWPT) to enhance the spelling performance and social interactions of three typical students and three students with mild disabilities was investigated. The classroom ecology was measured using the New Code for Instructional Structure and Student Academic Response (NCISSAR). Social interactions were assessed using the Multiple Option Observation System for Experimental Studies (M.O.O.S.E.S.). Spelling performance was measured by weekly pre-posttests. Using an ABAB single-subject design, results indicated that CWPT resulted in: (a) gains in the spelling accuracy of all students (up to 49%), (b) increases of students' duration of positive social interactions (up to 86%), and (c) high satisfaction ratings for both the students and the teacher. Comparisons between typical students and students with mild disabilities during CWPT suggested no differences in their duration of social interactions. Furthermore, the mean spelling accuracy of the students with mild disabilities was comparable to the spelling accuracy of the typical students (91% vs. 96%, respectively). Implications of the findings for the inclusion of students with mild disabilities in general education settings are discussed. 相似文献

Collaborative problem solving occurs in situations in which two or more individuals cooperate in appraising, representing,
and solving a variety of cognitive tasks. Collaborative groups are the context for much everyday cognitive activity in adulthood.
Collaboration has been explored as a means through which older adults may maintain high levels of performance, perhaps compensating
for individual-level cognitive and neurological decline. This study explored the effects of collaboration (group size) and
adult age on solving both fixed- and unrestricted-alternatives 20 Questions tasks. Younger (M=24.3 years) and older (M=67.9 years) adults were randomly assigned to one of three homogeneous group size conditions: individuals, dyads, and tetrads.
Results indicated some dissociation between individual-level performance (poorer for older adults) and collaborative performance
(better for older adults). For the fixed-alternatives task, older adults produced more of the relatively inefficient hypothesis-scanning
questions than did younger adults. In contrast, older collaborative groups produced more of the efficient constraint-seeking
questions than hhpothesis-scanning questions, and an amount equivalent to that of younger adults. Overall performance for
the difficult unrestricted-alternatives task was less efficient for both younger and older adults. The roles of task type,
group characteristics, and adult age are discussed. 相似文献

In Experiment 1 it was demonstrated that interference with a rat's retention of a target spatial cue decreases as the interval between prior conflicting cues and the target increases. Experiment 2 showed that interference can occur even when the interstimulus interval is long, if the memory of a conflicting cue is reactivated just prior to exposing an animal to the target cue. A third experiment suggested that these findings could not be easily interpreted in terms of a stimulus satiation effect. The implications of these findings for a trace decay model of short-term retention were discussed. 相似文献

The Adjustment Scales for Sociometric Evaluation of Secondary-School Students (ASSESS) was designed to assess peer ratings of the behavior of male and female adolescents. Five scales were developed and crossvalidated: Aggression-Disruptiveness, Withdrawal, Anxiety, Social Competence, and Academic Difficulty. Evidence of adequate internal consistency and testretest reliability was presented. Evaluations by male and female classmates were highly correlated. Sex and age differences accounted for only a small proportion of the total variance.This research was supported by Grant MH-21145 from the National Institute of Mental Health and funds from W. T.

We wish to acknowledge the assistance of Ronda Brooks, Lina Jandorf, and Jean Sullivan in conducting the data collection, as well as the many school districts that have cooperated. 相似文献

We report 2 studies that served to clarify the role of consumption emotions in the satisfaction response. In the 1st study, we examined the role of consumption emotions within the expectancy‐disconfirmation model of consumer satisfaction and investigated whether consumption emotions are a result of product performance or disconfirmation. The findings show that both positive and negative emotions are primarily a function of product performance and influence satisfaction even when the effects of expectations, performance, and disconfirmation are controlled. In the 2nd study, we proposed and tested an alternative framework for understanding the role of consumption emotions in the satisfaction response for situations in which consumers use more of an experiential perspective to anticipate and experience consumption. According to this model, consumers form affective expectations about how consumption of the product will make them feel, experience positive or negative emotions as a result of these expectations and product consumption, and evaluate the discrepancy between experienced and anticipated emotions. All 3 variables, then, impact satisfaction. The results empirically support many of the relations in the new model of the experiential satisfaction response but also raise several interesting avenues for future research. 相似文献

The Devereux Scales of Mental Disorders (DSMD), with its 3-factor model of measurement (i.e., Internalizing, Externalizing, and Critical Pathology), may be useful in screening for psychotic disorders in children. This study assessed the ability of the DSMD to differentiate between inpatient children and adolescents with psychotic disorders (n = 18) and those with other clinical syndromes (n = 71). Results of ANCOVAs indicated that the psychotic group scored significantly higher on most DSMD scales and composites than the nonpsychotic clinical group. However estimates of effect size were particularly large for the Critical Pathology Composite and the Autism and Acute Problems Scales. Diagnostic efficiency statistics revealed that the DSMD's Critical Pathology Composite was highly accurate in differentiating between the 2 clinical groups. These findings support the utility of the DSMD in identifying children and adolescents with psychotic disorders. 相似文献
