Children with specific reading retardation were matched with controls on the basis of age, sex, intelligence, and (less successfully) parental education. All subjects were tested on a variety of automated performance tests including the Matching Familiar Figures (MFF) Task, Auditory-Visual Integration, Short-Term Memory, the Continuous Performance Task (CPT), and Motor Performance. All children were assessed socially using the Conners Teacher Questionnaire, and reading-retarded children were rated on the Behavior Problem Checklist. Finally, all children were screened with the Finger Twitch Test and were assessed for left-right awareness. Statistical analysis suggested that the following performance tests discriminated between the groups in this respective order of importance: MFF (Accuracy), Auditory-Visual Integration, and the CPT. The Short-Term Memory Task, MFF Decision Time, and Motor Performance did not distinguish between the groups. Multiple regression equations suggested that scores on the performance tests could account for about 40% of the variance in reading attainment. Several factors from the rating scales (notably those pertaining to attention and anxiety) and left-right awareness also discriminated between the groups.This study was supported by a grant from the Medical Research Council of New Zealand to Prof. J. S. Werry (Grant MRC 151). The author would especially like to thank John Werry, M. D., Malcolm Gill, Ph.D., and the staffs of the official Remedial Reading Clinics and Psychological Services as well as those of Epsom Normal, Mount Eden Normal, Newmarket, and Parnell primary schools for the willing support they all rendered this project.  相似文献

This study tested the hypothesis that schizophrenics employ more developmentally immature levels of decentering in their structuring of interpersonal relations. A 9-point scale of interpersonal decentering, developed originally by Feffer, was applied to Thematic Appercetion Test stories produced by schizophrenic adolescents and a control group of psychiatrically disturbed patients equivalent in age and intellectual functioning. Results provided convincing support for the hypothesis tested and suggest the theoretical utility of viewing interpersonal deficit in schizophrenia from a cognitive-developmental perspective.  相似文献

Summary In this investigation, the effectiveness of tactual maps for the blind was tested. Four different pseudomaps were constructed; they differ on the one hand in type of construction (channel vs. track construction) and on the other hand in degree of complexity (low vs. high complexity).Depending on the experimental condition, blindfolded sighted Ss had to learn one of the four maps (10 Ss for each type). Afterwards they had to reproduce the maps by drawing them. The accuracy of their performance was measured in two different ways (free reproduction and reproduction with correction). In addition, the memory and spatial imagery of the Ss were measured by two psychological tests.The overall result of the study was that reproduction is better for tactual maps with channels than with tracks. This result is valid for maps with low as well as high complexity. Furthermore, maps with channels are more widely usable, since with this type of map, good memory and spatial imagery are not prerequisites.  相似文献

As human relations skills are more widely taught and used, they are inevitably misused as well, often by some particularly fowl aggressors. This article is intended as a brief self-defense course identifying those who undergo this strange, but usually temporary, metamorphosis into “turkeys.” It provides a rough categorization of subspecies with their identifying characteristics and a proposal for return to personhood.  相似文献

Academic advisement has traditionally been thought of as limited to such routine functions as course registration and academic record-keeping. Advisement, however, should be redefined so that developmental functions are central. It would then perform a much-needed service in higher education, for students need assistance in planning academic programs and integrating academic, career, and life goals. Faculty and advisors will need to learn some unaccustomed roles (counselor, advocate, and guardian) as well as some new skills. With appropriate support, however, acceptance of developmental advising will be possible.  相似文献

A program was designed to teach coin equivalence to mentally retarded adolescents. Coin equivalence was defined as choosing several different combinations of coins to equal specified target values. A pretest-posttest matched-groups design was employed with an experimental group receiving the monetary training, and a no-training control group. A multiple baseline across coin-counting responses was also incorporated in the experimental group. Training was divided into six stages, each teaching one specific method of combining coins to equal 10 target values from 5¢ through 50¢. A three-component response chain was used, requiring (a) naming, (b) selecting and counting, and (c) depositing target monetary values into a coin machine. Experimental subjects improved significantly in coin equivalence performance and maintained their skill on follow up tests; control subjects did not.  相似文献

Skin conductance responses were examined bilaterally in a group of 14 normal subjects. Twelve of them were right-handed and two were left-handed. All right-handed subjects exhibited asymmetry in skin conductance level and in skin conductance response during verbal-numerical and visual-imagery tasks. With the visual activity, larger responses were found in the left hand, while during the verbal task, larger responses were recorded from the right hand. The results were interpreted as evidence of hemispheric asymmetry of the electrodermal activity orienting response control mechanisms. More ipsilateral control for the right hand is predicted.  相似文献

This study investigated whether some types of disfluency are perceived as more severe than others and if listener groups differ in their perception of severity for some disfluency types. Three normal speaking children were trained to produce eight types of disfluency and one sample of fluency. The experimental tape, consisting of three examples for each of the eight disfluency types and of fluency, was presented auditorily to 40 judges divided into four groups of 10 each: parents of stutterers, parents of nonstutterers, speech clinicians, and elementary school teachers. The judges rated the disfluency and fluency on a 15-point severity continuum, divided into four nominal categories of Fluent, Normal Disfluency, Mild Stuttering, Moderate Stuttering, and Severe Stuttering. Results showed that although listener groups did not significantly differ in their severity ratings, the specific types of disfluency did differ significantly. The type of disfluency emitted by a speaker is apparently more salient in perceiving and judging disfluency than the type of listener making the judgment.  相似文献

Tucker has outlined an application of principal components analysis to a set of learning curves, for the purpose of identifying meaningful dimensions of individual differences in learning tasks. Since the principal components are defined in terms of a statistical criterion (maximum variance accounted for) rather than a substantive one, it is typically desirable to rotate the components to a more interpretable orientation. Simple structure is not a particularly appealing consideration for such a rotation; it is more reasonable to believe that any meaningful factor should form a (locally) smooth curve when the component loadings are plotted against trial number. Accordingly, this paper develops a procedure for transforming an arbitrary set of component reference curves to a new set which are mutually orthogonal and, subject to orthogonality, are as smooth as possible in a well defined (least squares) sense. Potential applications to learning data, electrophysiological responses, and growth data are indicated.Portions of this research were supported by the National Research Council of Canada, Grant A8615 to the second author.
