On the basis of previous research findings, 32 new items were added to Super's Work Values Inventory (WVI) and the resulting 77 item instrument was administered to 611 high school sophmores. Guttman's rank-reduction procedure and separate image analyses were employed to examine empirically the effects of additional items on hypothesized item groupings, scale intercorrelations, factorial dimensions, and scale internal consistency reliabilities. Analyses supported the addition of items to the WVI. It was found that the item groupings on the modified instrument were reasonable; the scale intercorrelations and factorial dimensions of both versions were highly comparable; the addition of items had increased the scale internal consistency reliabilities. Comments were made regarding counselors' use of the WVI. 相似文献

This study assesed the extent to which Ss commit various types of errors when completing Holland's Self-Directed Search (SDS) entirely on their own. Nearly all Ss made some type of error and approximately half of the Ss made errors which affected their final three-letter summary codes. Almost one-fifth of the Ss made errors resulting in an incorrect high-point code. Whether or not Ss made errors that affected their summary codes was unrelated to the extent to which they were interested in knowing more about occupations or academic majors they might like. Neither were such errors related to whether Ss felt the occupations suggested by their summary codes seemed reasonable. Only slightly over one-third the Ss actually did feel that the occupations seemed reasonable. 相似文献

Female clerical workers were rated on seven dimensions of job performance using behaviorally based rating scales, these 266 subjects responded to questionnaire items concerned with their expectations dealing with (1) whether their job effort resulted in effective performance (Expectancy I), and (2) whether job performance leads to reward outcomes (Expectancy II). These Expectancies were found not to be highly related to the measures of job performance in contrast to expectancy theory predictions. Satisfaction with reward outcomes was found to be differentially related to individuals' expectations that performance results in the attainment of particular outcomes. 相似文献

A study investigated persistence as a function of two variables: the disposition to be self-attentive (called private self-consciousness) and outcome feedback on a prior task that was described as closely related to the target task. More specifically, subjects first completed a concealed-figures test and were told that their performances were either very good or very poor. The second test, which ostensibly measured the same abilities, was an insolvable design problem that is commonly used to measure persistence. Feedback concerning prior outcomes had a direct influence on expectancies for the second task, but persistence on that task was a joint function of feedback and self-consciousness. That is, favorable feedback led to greater persistence than did unfavorable feedback, but only among subjects high in self-consciousness. This finding replicates and extends the results of several previous studies. Discussion centers on the relationship between the present research and an earlier experiment which yielded apparently different results. 相似文献

The effects of syllable structure on the development of phonemic analysis and reading skills were examined in four experiments. The experiments were motivated by theories that syllables consist of an onset (initial consonant or cluster) and a rime (vowel and any following consonants). Experiment 1 provided behavioral support for the syllable structure model by showing that 8-year-olds more easily learned word games that treated onsets and rimes as units than games that did not. Further support for the cohesiveness of the onset came from Experiments 2 and 3, which found that 4- and 5-year-olds less easily recognized a spoken or printed consonant target when it was the first phoneme of a cluster than when it was a singleton. Experiment 4 extended these results to printed words by showing that consonant-consonant-vowel nonsense syllables were more difficult for beginning readers to decode than consonant-vowel-consonant syllables. 相似文献

Kidney donation by young children and the mentally retarded has been supported by court decisions, arguments based on obligations inherent in family relationships, an array of contextual factors, and the principle of beneficence. These justifications for taking organs from people who cannot protect themselves are problematic and must be weighed against our obligation to protect the vulnerable. A compromise solution is presented that strongly protects young children and the mentally retarded but does not abdicate all responsibility to relieve suffering. Guidelines are proposed that prohibit the retrieval of kidneys from young children and the mentally retarded but permit one exception. They would allow retrieval of a kidney when the consequence to a first order relative with whom the donor has a meaningful and valuable relationship is otherwise imminent death. This would be done in accordance with additional guidelines that minimize harm to the donor. Since most patients with end stage renal disease can be maintained on dialysis the need for a kidney to prevent death should be an uncommon occurrence. This compromise is proposed as a solution to a dilemma that exists because two ethical principles are in conflict and one cannot be honored without violating the other. 相似文献

This investigation evaluated the use of directed rehearsal to improve the teaching behaviors of four preservice elementary physical education teachers during a teaching practicum. Directed rehearsal consisted of two phases: (a) initial feedback following baseline, review of teaching behaviors, and rehearsal; and (b) rehearsal contingent upon errors made during each lesson. Three teaching behaviors were assessed using a multiple baseline design across behaviors for each teacher. Social validity in the form of the acceptability of directed rehearsal as a teacher training intervention also was assessed using a questionnaire. Results indicate that directed rehearsal was effective in improving the teaching behaviors of the four teachers in this study to 100% correct implementation. In addition, the intervention was acceptable to the teachers and the class instructor. 相似文献

A series of three eyelid-conditioning experiments with rabbits examined the traditional extinction procedure in which the CS is presented in the absence of US presentations. The first study employed a savings test to demonstrate that the rate of reacquisition is faster after a conventional extinction procedure than after a procedure in which the CS and US have been unpaired. The second experiment indicated that this readiness to respond in reacquisition was related to a carry-over effect from the initial acquisition trials. The third study demonstrated that acquisition and reacquisition are similar when the US is maintained in extinction but not when it is omitted. These results imply that procedures which retain the US during extinction are more effective than the conventional CS-alone extinction procedure in eliminating or inhibiting the associative connection between the CS and the US. 相似文献
