The primary index of reflection- impulsivity is Kagan's Matching Familiar Figures Test (MFF), which yields both a latency and an error score. To evaluate further the construct validity of these measures, both the latency and error scores of 9- and 15-year-old normal and acting-out behavior-disordered children were compared. Young behavior-disordered children were found to be more impulsive than the other groups on the MFF error measure. No differences occurred on the MFF latency measure. This result is consistent with previous findings with normal children in supporting the construct validity of the MFF error score and raising questions about the construct validity of the MFF latency score. Findings were inconsistent with Kagan's assertion that normal children become more reflective with age. The older behavior-disordered children were more reflective on the error measure than the younger behavior-disordered children and had equivalent error scores to both age groups of normals. This finding suggested a lag in the development of reflection in behavior-disordered children.The authors wish to thank Dr. Kenneth C. Molkner for his valuable assistance in obtaining subjects and for his kind support.  相似文献

Current on-line assessment applications are limited to mimicking instruments designed for paper and pencil. The development of an instrument designed specifically for on-line technology is described. The instrument provides research data on treatment effectiveness, clinical information for treatment planning, and management information for resource allocation.  相似文献

Several facets of the homemaker job were analyzed in terms of the dynamic relationship between husband and wife. Seventy-one husband and wife pairs completed a questionnaire which assessed satisfaction with the homemaker job, marital satisfaction, distribution of responsibility for homemaker tasks between husband and wife, and other variables. Wives' satisfaction with the homemaker job was found related to the degree to which husbands assumed responsibility for homemaker tasks and to the husbands' attitudes toward women in general. Wives' marital satisfaction was found related to the interaction of wives' employment status (job holder or full-time homemaker) and satisfaction with the homemaker job. Directions for future research in this area were suggested.  相似文献

This study examined, for 221 black and white male and female college students, the relationship between the Motive to Avoid Success (M−s) and: (a) sex and race; (b) congruency, consistency, and differentiation of occupational choice; and (c) occupational aspirations. M−s was assessed by a recent scoring system for verbal TAT cues and occupational choice patterns were analyzed by the Self-Directed Search. The results showed a significant sex difference on M−s. High M−s, in white females predicted well defined, sex-role stereotyped, and low occupational aspirations, but for white males it predicted high aspirations. No significant results were found for black males, and M−s in black females seemed to be related to economic well-being.  相似文献

It has been observed that the number of different ways in which a graph withp points can be labelled isp! divided by the number of symmetries, and that this holds regardless of the species of structure at hand. In this note, a simple group-theoretic proof is provided.This work was supported by Grant MH 10834 from the National Institute of Mental Health.  相似文献

The Rockefeller University, New York, New York 10021 Events such as barpresses or licks, which may occur at any time during the day, are often clustered into bouts. The internal structure of such bouts can be recorded using an AM tape recorder, running the tape recorder only while bouts are in progress, and can later be analyzed off-line on a digital computer.  相似文献

Rates of GSR habituation, reactiontime responses, and observational ratings in normal and learningdisabled children were evaluated. Compared to normals, children with learning disabilities demonstrated faster rates of GSR habituation in a task involving active attention, slower reactiontime responses, and more characteristics of “minimal brain dysfunction” on a rating scale. Within the learningdisability group those subjects with a family history of reading problems showed fewer GSR, reactiontime, and rating responses characteristic of “minimal brain dysfunction.”  相似文献

A quantitative method is developed for assessing the quality of pattern information in imagery, using the magnitude of color aftereffects as an objective index. Subjects were given instructions to project imagined bar patterns of particular width and orientation onto adapting color fields, in such a manner as to simulate standard conditions for establishing the McCollough effect. Our control procedures indicate that the resulting orientation-specific complementary color aftereffects cannot be attributed to the conditioning of particular directions of eye scanning movements to color processing during adaptation, or to other possible sources of experimental bias. Furthermore, subjects who rated themselves prior to the adaptation procedure as having relatively vivid imagery showed significantly larger aftereffects than those who reported having relatively low imagery. These results not only provide an important confirmation of our earlier finding that imagination can replace physical pattern information in the formation of basic color-feature associations in the human visual system, but also demonstrate that these aftereffects can provide a practical measure of the fidelity of pattern representation in visual images.  相似文献
