Performances of noncollege student young adults, middle-aged adults, and elderly adults were contrasted on word temporal memory and paired-associate learning tasks. A comparison group of college-student subjects was also evaluated on each task. Significant effects for age variation were found for each task. The age sensitivity for temporal memory conflicts with one of the criteria commonly established for determining the automaticity of a memory task. In addition, moderately high positive correlations were found for each age group between word temporal memory scores and paired-associate learning scores, implying the involvement of effortful processes over the adult lifespan in word temporal memory. 相似文献

A comparison of two measures of egocentrism 总被引:1,自引:0,他引:1

This study examined the relationship between two prominent measures of egocentrism, Enright's Adolescent Egocentrism Scale (AES) and Elkind's Imaginary Audience Scale (IAS), in a sample of 458 adolescents, between 10 and 15 years old. Both correlational and factor analyses indicated that the two measures assess distinctly different phenomena. As predicted, IAS scores were correlated with self-reported levels of shyness, nervousness, and social skills. These results provide partial evidence for the validity of the IAS as a measure of self-consciousness, though not necessarily egocentrism per se. The validity of the AES was not examined. 相似文献

Fifteen male and 15 female American therapists-in-training (clinical and counseling psychology graduate students) were asked to take the Minnesota Multiphasic Personality Inventory (MMPI) under each of two instructional sets. In one set, they were instructed to respond to the items as a healthy male would respond, and in the other, as a healthy female would respond. The MMPI profiles obtained from male and female subjects were not significantly different, indicating that these male and female therapists-in-training did not differ in their perceptions of healthy men and women. When the data for male and female subjects were combined, however, healthy women were perceived differently than healthy men on several scales, although the MMPI profiles obtained under both instructional sets were well within normal limits. 相似文献

The relationship between primary process thinking and two measures of anxiety was investigated in fourth- and fifth-grade children. Holt's Scoring System for Primary Process Responses on the Rorschach was the measure of primary process thinking. The major hypotheses were supported for boys in that frequency of expression of primary process material was positively related to behavioral manifestations of anxiety as measured by the Teacher's Rating Scale. Also, controlled access to and integration of primary process was negatively related to teacher's ratings of anxiety. There were no significant results for girls. Primary process measures were not related to the State-Trait Anxiety Inventory for Children. Possible reasons for the different relationships between the primary process measures and the anxiety measures are discussed. 相似文献
