The relationships between intelligence test scores and measures derived from reaction time (RT) and perceptual speed procedures were investigated in 137 twelve-year-old students with IQs ranging from 59 to 142. A range of intelligence tests were used and the scores factor analyzed to produce general, spatial and verbal factors. Test and factor scores were correlated with perceptual speed and with measures taken from 2, 4, and 8 choice RT tasks using a response keyboard upon which the subject's fingers directly rested, thus avoiding interpretive problems associated with a “home key.” Inspection time correlated poorly with intelligence. Only three of the RT measures produced correlations greater than .25 with the general factor. These were the slope of Hick's law, B, (correlation −.28), the 8 choice mean RT, RT8, (−.33) and the 8 choice standard deviation, SD8 (−.41), compared with the average intercorrelation between the intelligence measures of .40. Test-retest correlations of the RT measures, taken over a year for half the subjects, were low as reliability measures, with .35 for B, .52 for RT8, and .48 for SD8. Correlations of RT measures with spatial scores were not significantly greater than with verbal scores, suggesting that whatever relationship exists is with a general factor rather than only a spatial one. 相似文献

Kindergarten and third grade boys learned an intermediate-size problem either visually or tactually. They were then tested either visually or tactually. The test sets were separated from the training set by either 1, 2, or 4 steps. The data supported predictions derived from the D. M. Lane and F. M. Rabinowitz (Child Development 1977,48, 412–426) transposition theory on choice and consistency measures. Of greatest interest were the markedly different transposition gradients exhibited by the boys in the visual-visual and visual-tactual groups. 相似文献

Two groups of children, one of below average intelligence and one of above average intelligence, were adminitered nine tasks involving matching information between auditory and visual modalities and temporal and spatial presentations. The below average intelligence children made more matching errors than the above average intelligence group, with no indication that matching problems were particular to one modality or particular to cross-modal as opposed to intramodal matching. Factor analyses did suggest, however, that matching processes varied according to levels of intelligence. The results are discussed in terms of the differences between modality-specific and nonmodal theoretical views of sensory systems, and it is noted that neither view alone is adequate to account for the variations found for the two intelligence groups. It is suggested that the results are consistent with Luria's research on neurological organization. 相似文献

This study demonstrates that agrammatic aphasics have difficulty describing relations that are signified by the order of noun phrases around verbs or prepositions. The word order deficit is found in a Sentence Order Task, in which written words must be arranged linearly to form a sentence, as well as in oral production. Ordering tendencies reflect factors like animacy or potency, rather than the systematic use of syntactic rules. These results point to a fundamental syntactic disorder in agrammatism. 相似文献

Sixty-four subjects, divided into four groups of 16 according to sex and familial sinistrality (FS), were given a lateralized Object-Naming Latency Task (ONLT) and a Lexical Decision Latency Task (LDLT). Both tasks showed RVF superiorities. On the ONLT a sex × FS × visual field interaction was obtained, with FS− females and FS+ males showing comparably smaller RVF superiorities than FS+ females and FS− males. On the LDLT an FS by Stimulus Type (word-nonword) interaction was found, FS− subjects being more RVF superior for nonword trials and FS+ subjects more RVF superior for word trials. If one compared only FS− males and females, as some studies have done, greater RVF superiorities obtained for males than females on both the ONLT and word trials of the LDLT. However, FS+ subjects showed the opposite pattern. The data support neither the simple model of FS nor sex influence on language laterality. Data aslso suggest that a history of maternal versus paternal left-handedness may affect lateralization differently in the sexes. 相似文献

Previous research has investigated two diverse operational definitions of stress, experimentally induced, short-term stress and long-term, life stress. The purpose of this study was to intersect these two research methodologies and determine the effect of a laboratory-induced stress (failure feedback) on persons with differing levels of life stress. Women with high or low amounts of life stress were given failure feedback, no failure feedback, or a cognitive coping strategy (affective isolation) in addition to failure feedback. Failure feedback increased self-reported anger and anxiety immediately following feedback and also after a follow-up test and decreased expectations about performance for the second test. Affective isolation significantly reduced anger and anxiety but failed to affect expectations. Women with high amounts of life stress reported significantly less anxiety than women with low amounts of life stress in response to failure feedback. These results were interpreted within C. D. Spielberger's (in C. D. Spielberger & R. Diaz-Guerrero (Eds.), Cross-cultural anxiety, New York: Wiley, 1976) cognitive model. It was proposed that differing levels of previous life stress cause people to make varying judgments about the degree of threat in a short-term stressful situation. Persons with high amounts of life stress may not be aroused in response to short-term stress because they perceive the short-term stress as only a “drop in the bucket” compared to the other events which they have experienced. 相似文献
