A 20-item adjective checklist was used by 118 retired educators to describe their actual and retrospective-occupational self-concepts. The men made their retrospective ratings for middle-aged and preretired occupational roles. The intercorrelations among the self-concept ratings were multiple-set factor analyzed, and seven common dimensions were identified: (1) stability, (2) conventionality, (3) independence, (4) practicality, (5) status, (6) confidence, and (7) cleverness. The results suggested that the retired educators had used the same dimensions in describing their actual and retrospective-occupational self-concepts. The percentages of variance contributed by the dimensions within the self-concept structures were also reported and discussed within the framework of career development.  相似文献

Contingent social isolation was investigated as a punishment procedure for the disruptive behavior of emotionally disturbed children in a classroom setting. The methodological limitations of previous studies were outlined, and alternatives adopted. Within a reversal and multiple baseline design, contingent social isolation was found to be an effective and relatively specific punisher. By introducing a new observation procedure, “pseudo-timeout”, it was determined that the punishing effect of social isolation was not attributable to observation artifact. A means for resolving the terminological confusion in the present use of timeout and social isolation was recommended.  相似文献

Four- to seven-year-old children observed a simple physical effect which could be attributed to either a consistent but noncontiguous covariate or a contiguous but inconsistent covariate. When there was a physical rationale for the temporal delay between covariate and effect, children attributed the effect to the consistent but noncontiguous covariate. In the absence of such a rationale, they attributed the effect to the contiguous but inconsistent covariate. It was concluded that neither consistent covariation nor strict temporal contiguity were essential aspects of causal inference for these children.  相似文献

This study was designed to investigate the development of knowledge about categorical and associative relationships as reflected by the presence or absence of semantic priming effects. Kindergarteners and second-graders were shown pairs of pictures, one picture at a time, and asked to name each picture as rapidly and accurately as possible. Picture pairs were of four types which reflected the factorial combination of associative relatedness (high and low) with categorial relatedness (high and low). An analysis of naming times revealed a significant main effect of associative relatedness, i.e., second pictures or “target” pictures in high-associative pairs were named faster than those in low-associative pairs. This reduction in naming latency, or priming effect, was independent of developmental level. However, the effects of category relatedness varied with developmental level, i.e., target pictures in high-categorical pairs were named significantly faster than those in low pairs by second-graders, but not by kindergarteners. These findings are discussed in terms of previous estimates of children's semantic competence.  相似文献

A 2 (aid vs no aid) × 2 (high vs low resource potential donor) between subjects design tested the effects of aid and donor resources on recipient self-perceptions and subsequent self-help behavior. The results were characterized by interactions between the two factors. Subjects who received aid from a low resource donor perceived themselves more positively and engaged in less self-help than subjects in the no-aid low resource potential donor condition. In contrast, subjects who received aid from a high resource donor perceived themselves less positively and tended to engage in more self-help behavior than subjects in the no-aid high resource potential donor condition. The relationship between threat to self-esteem inherent in aid and subsequent self-help is discussed in terms of self-esteem theory.  相似文献

The accuracy with which people execute wrist and elbow movements were measured using three main conditions: (i) single-jointed (wrist or elbow) movements to targets, (ii) dual-jointed (wrist and elbow) movements to targets, and (iii) components of dual-jointed movements to targets, when the task for the subject was to perform the elbow or wrist constituent of the action in isolation, without displacing the second joint. Elbow precision was significantly worse under component than dual conditions, which is compatible with the notion that wrist and elbow activity are conjugately, rather than independently, programmed when a dual-jointed action is performed. The pattern of wrist accuracy was divergent, but possible reasons for this were discussed. In all cases, error was measured in terms of deviation from perfect posture; using this index, the hypothesis that incorporating more moving joints into an action serves to increase movement complexity and jeopardise precision was tested, but the results were ambiguous. Discussion also centered on the problems of using performance data to infer changes in motor programming, and the need for rigorous conceptualisation and research in this area.  相似文献

Caregiver-child interaction and social participation were compared in community-based day care centers and group day care homes for three year olds. Use of group day care homes made it possible to control for group size and adult-child ratio. Day care homes were found to be more structured in terms of curriculum, and more flexible in terms of overall schedule and social-emotional climate. Adult child interaction was of higher quality during structured periods in day care homes. Social participation was of higher quality in day care homes. The adult-child interaction in both types of day care was impersonal and neutral in affective tone.  相似文献

E. K. Strong, Jr.'s (Vocational interests of men and women, Stanford, Calif.: Stanford Univ. Press, 1943) four propositions for interest-inventory validity andJ. L. Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) hexagonal classification system were synthesized in order to adapt a traditional procedure for determining the construct validity of occupational interest scales to the validation of basic interest scales. The procedure was tested using a sample of 4035 males and 3671 females whose interest inventory results as high school students and whose majors as college seniors could be assigned Holland codes. Results of the study indicate that this procedure can be used to assess the construct validity of inventories using basic interest scales.  相似文献
