The attention-demand value of the Rorschach stimuli was investigated by measuring free looking time elicited by each card. Reports of content were not given by Ss. There were significant differences between cards in amount of looking which they elicited. This was closely related to judged complexity of the cards (r = .78) and response productivity of the cards under normal administration of the Rorschach test (r = .72). A comparison of looking times under two instructions, non-defensive and defensive, showed that the instructional variable tended to produce greater differences in looking time for some cards than for others. Cards low in complexity showed relatively longer looking times under the defensive conditions.  相似文献

We examined the factor structure of the Neuroticism scale of the Eysenck Personality Questionnaire (EPQ–R–N; S. B. G. Eysenck, Eysenck & Barrett, 1985) and its factor invariance across sex and racial/ethnic groups in a sample of 1,979 adolescents. Using confirmatory factor analyses, we compared a hierarchical model to previous models of the EPQ–R–N and to single-factor and 3-factor structures. The hierarchical factor structure in which a general factor coexists with 3 group factors (depression, social concerns, and worry) was superior to alternative models. The general factor accounted for more than 60% of the variance in EPQ–R–N total scores and was invariant across sex and ethnicity. The 3 group factors varied across ethnicity and sex. We discuss the implications of these findings for conceptualization and assessment of neuroticism using the EPQ–R–N.  相似文献

GAT and TAT themes of normals with an age range of 59–94 years were analyzed to determine the comparative efficacy of each instrument to elicit themes depicting loss of sexuality, loss of attractiveness, family difficulties, physical limitations, and dependency. In only the area of physical limitations, did the GAT more successfully elicit relevant themes than did the TAT.  相似文献

A follow-up was made of 18 male dyslexic children (RDs) and a group of matched controls (Cs), who had all been judged free from emotional and school adjustment problems two years earlier, (a) to see if RDs' reading deficit had been overcome, (b) to measure “emotional overlay,” and (c) to find predictors of success in learning to read. Results showed that at the time of the follow-up (a) none of the RDs had overcome his reading disability despite remediational efforts; (b) RDs had significantly lower achievement levels and significantly more adjustment problems than Cs; (c) low scores for WISC Full Scale IQ, Vocabulary subtest, and Coding subtest were associated with large reading deficits two years later; and (d) high WISC Arithmetic and Coding subtest scores were associated with large gains in reading skill. Physiological measures did not predict size of deficit or gain in reading skill over time.  相似文献

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.  相似文献

An examination of the relationship of scores on Siegel's Manifest Hostility Scale (MHS) to Verbal Hostility, Fantasy Hostility, and Hostile Feeling responses to cartoon situations was undertaken, while controlling for sex of subject, sex of experimenter, and the social desirability (So-R) and ego strength/defensiveness (K) scales of the MMPI. MHS scores were significantly related to the three modes of hostility response, while sex of subject and sex of experimenter were not. Adjustment of the dependent variable means for So-R did not cancel MHS effects on Verbal or Fantasy Hostility, but adjustment for K cancelled the significant relationship between MHS scores and Fantasy Hostility and Hostile Feeling responses. Covariation of both K and So-R out of Verbal Hostility cancelled its relationship to MHS scores. Ego strength/defensiveness thus may be more significantly related to hostile responding than social desirability.  相似文献

The current study used a randomized controlled trial to compare the effects of a practice-based intervention and a mnemonic strategy intervention on the retention and application of single-digit multiplication facts with 90 third- and fourth-grade students with math difficulties. Changes in retention and application were assessed separately using one-way ANCOVAs in which students' pretest scores were included as the covariate. Students in the practice-based intervention group had higher retention scores (expressed as the total number of digits correct per minute) relative to the control group. No statistically significant between-group differences were observed for application scores. Practical and theoretical implications for interventions targeting basic multiplication facts are discussed.  相似文献
