Measures of need Achievement, need Affiliation, and need Power were obtained for 124 working managers (62 female, 62 male) using both McClelland's traditional male-oriented thematic apperception test (TAT) and a set of picture cues balanced-as-to-sex. Two-way analysis of variance was performed in a 2 x 2 factorial design (sex by version of TAT). F tests were conducted to test significance at the .05 level. Results indicate both sets are interchangeable in determining need Achievement and need Power distinctions between managerial women and men, Absolute scores are also comparable. For need Affiliation, however, motivation scores are not comparable and interchangeability is clouded, suggesting cue modification may be needed. 相似文献

Although the Bender-Gestalt Visual Motor Test has been a popular and influential clinical assessment instrument for the last half century, authoritative opinion and a substantial research literature are often inconsistent or contradictory. This paper documents variations in designs, administration procedures, forms, and applications to particular populations. A careful review of scoring systems indicates the current status of objective approaches as contrasted with interpretation that is global, intuitive, and subjective. Some implications of these variations and interpretive procedures for training and assessment practice are discussed. The major conclusions of the review are summarized in seven points. 相似文献

The reliability and concurrent validity of alternative methods for assessing ego development 总被引:1,自引:0,他引:1
This study demonstrates that an unstructured interview (INT) and the Thematic Apperception Test (TAT) are suitable alternatives to Loevinger's Sentence Completion Test of Ego Development. Seventy subjects were solicited from six groups varying widely with respect to age and education level. Each subject was asked to complete the SCI, an INT and the TAT. Two raters using Loevinger and Wessler's self-training exercises and Loevinger, Wessler, and Redmore's scoring manual rated subjects' responses to each instrument. Reliability was found between raters and concurrent validity between instruments. Subjects scoring high on the SCT were found to score higher on the INT and TAT. 相似文献

Loneliness, social interaction, and sex roles 总被引:3,自引:0,他引:3
Forty-three male and 53 female college seniors maintained the Rochester Interaction Record for 2 weeks, providing information about every social interaction of 10 minutes or more. Subjects then completed the revised UCLA (University of California, Los Angeles) Loneliness Scale and the Personal Attributes Questionnaire, measuring sex-role orientation. For both sexes, loneliness was negatively related to the amount of time spent with females and to the meaningfulness of interaction with males and females. However, meaningfulness with males was more important than meaningfulness with females. Femininity was negatively related to loneliness for both sexes and partially mediated the above relationships. There were sex differences, however, in the extent to which variables overlapped in predicting loneliness. For example, a large group of nonlonely males was characterized both by having meaningful relationships with males and by spending time with females, whereas a second group of nonlonely males was characterized simply by having meaningful relationships with males. The largest group of nonlonely females was characterized simply by having meaningful relationships with males, but another sizable group was characterized simply by spending time with females. Females doing both accounted for very little of the variance. 相似文献

Four pigeons were exposed to independent concurrent variable-interval 20-second variable-interval 60-second schedules of reinforcement. A transparent partition was inserted midway between the two response keys. The length of the partition was systematically manipulated. Increasing partition length produced a decrease in changeover rate in Experiment 1. Over-matching was observed with a partition length of 20 centimeters. In Experiment 2 a four-second limited hold was added to the schedules. Increasing partition length produced a decrease in changeover rate that exceeded the decrease observed in Experiment 1. This manipulation produced nearly exclusive choice of the variable-interval 20-second component. The present results, together with results obtained in related research, suggest that deviation from matching is a function of procedural variables that determine the consequences of a changeover response. 相似文献

Although there were no significant differences in the single support phase of gait for 6 trainable mentally retarded boys (Mean age 9.6 yr.) and 6 nonretarded boys (Mean age 9.5 yr.), total gait time and time in double support were significantly different for the two groups, supporting previous research which showed gait was was deficient in trainable mentally retarded individuals. 相似文献
