Recent concern for eliminating Strong Vocational Interest Blank (SVIB) sex bias has focused on the current use of separately normed Occupational Scales for the two sexes. This study implemented six basic methods of scale construction to examine the feasibility of combined-sex scales as well as advantages or disadvantages of modifications of current techniques designed to improve both single-sex and combined-sex scale construction. To study these six methods of scale construction, samples of male and female Ph.D. sociologists were collected. Concurrent validity and test-retest reliability data indicated that combined-sex scale construction for sociologists is possible if differences in female and male occupational interests, as measured by the SVIB, are treated as irrelevant variables in the world of work, and if concurrent validity is sacrificed. 相似文献

Infants of 1, 2, and 3 months of age were presented with two checkerboard patterns, one stationary and the other moving in a horizontal oscillatory motion at one of eight rates. An observer who could see only the infant's head and eyes recorded, for each 30-sec trial, (a) the position of first fixation, (b) position of fixation at the end of each 5-sec interval, and (c) a final forced-choice judgment of the position of the moving stimulus. Results showed reliable differences in ocular behavior as a function of rate of stimulus motion for all three groups of infants. 相似文献

This study investigated the effects of group systematic desensitization and group counseling on anxiety and academic performance. Fifty-four undergraduates who requested help for debilitating test anxiety were randomly assigned to Desensitization. Group Counseling, or No-treatment control groups. Measures of test anxiety, trait anxiety, and academic achievement were obtained for all students' pre- and post-treatment. The Desensitization group showed a significant decrease in test anxiety; the Counseling and No-treatment groups showed no changes in these measures. None of the groups showed any change in trait anxiety or academic achievement. The results provided evidence that systematic desensitization was an effective treatment for reducing test anxiety, but not for improving grades. 相似文献

Recently. the proposition that alcohol abuse is an operant behavior and thus functionally related to its consequences has been investigated under experimental conditions. In controlled laboratory settings, in which inpatient chronic alcoholics are allowed access to alcoholic beverages, alcohol consumption has been markedly altered via operant strategies. Monetary rewards (Cohen et al., 1971), the opportunity to participate in an enriched environment (Cohen et al., 1971). and visits to a girlfriend (Bigelow et al., 1973) have been used as reinforcers for decreased drinking.Other investigators (Sulzer, 1965; Miller, 1972: Hunt and Azrin, 1973) have successfully applied similar contingency management techniques to alcoholics in the natural environment. However, failure to control for the influence of extraneous therapeutic variables (e.g., attention-placebo factors, job counseling) together with reliance on self-report measures of drinking behavior seriously limit the conclusiveness of these results. Objective assessment is particularly essential with operant techniques since consequent events must be systematically scheduled upon the occurrence or non-occurrence of drinking. Documentation of drinking in the natural environment is a difficult task since the alcoholic frequently consumes alcohol when he is alone. In lieu of direct observation, blood alcohol concentrations are an obvious means of objective assessment. Such data are most conveniently obtained via breath tests similar to the ones that law enforcement officers utilize to identify intoxicated motorists.The purpose of the present study was to investigate the influence of reinforcement contingencies on lowering blood alcohol concentrations obtained in an alcoholic's natural environment. 相似文献

Unassertive psychiatric patients matched on age, diagnosis, and self-reported assertiveness were assigned to one of five conditions, with 10 subjects in each group: Test-Retest, Practice-Control, Practice-Control with Generalization Instructions, Modeling and Instructions, Modeling and Instructions with Generalization Instructions. All subjects were videotaped (Pre- and Post-Test) while responding to ten interpersonal situations requiring assertive responses. Following the Pre-test, subjects in the experimental groups received training on five of the ten situations (training scenes). On the remaining five situations subjects received no training (generalization scenes). Results indicated that the Modeling and Instructions groups effected the greatest changes on seven of the eight components for the training scenes but on only five of the eight components for the generalization scenes. No differences were found between either of the two Practice-Control groups and the the Test-Retest group. Although transfer of training effects were obtained on the generalization scenes, these effects were minimal on an independent in vivo test of generalization. Moreover, an instructional set designed to facilitate generalization to different situations was only partially effective. 相似文献

The stimulus-familiarization-effect (SFE) paradigm, a reaction-time (RT) task based on a response to novelty procedure, was modified to assess response for novelty, i.e., a response-reinforcement sequence. Ninetysix kindergarten children were familiarized on one of two colored lights. Then Ss were confronted with a simple position discrimination task in which they could choose between two response buttons which produced either the previously familiarized light or a new (i.e., novel) light. Results showed that the choice response for the novel stimulus (NS) was facilitated by three variables: number of exposures to and duration per exposure of the familiar stimulus (FS), and degree of change provided by the NS relative to the FS. The parallel between the effective variables of this study and those which produce the SFE was noted, implicating an attention interpretation of the function of novelty as a reinforcer. The potential implications of attention for reinforcement theory and learning in general are discussed. 相似文献

An experiment was conducted investigating the effects of training two components of a dimension-abstracted oddity problem, oddity responding and attention. All Ss were given a series of three problems. Type of oddity training was manipulated on Problem 1, and Ss learned (1) an oddity response in a problem whose format was the same as the final transfer problem, (2) an oddity response in a problem whose format was different from the final problem, or (3) no oddity response. Attention training was manipulated on Problem 2. The results indicated that Ss given same format oddity training and appropriate attention training were able to integrate that information on the final problem, that the probability of transferring the oddity response learned on Problem 1 to Problem 3 depended upon the similarity of the task formats, and that the two trained components tended to combine in an interactive fashion. 相似文献

Recent investigations concerned with the analysis of work motivation and job satisfaction constructs have combined the logic of subgrouping with an emphasis on the importance of individual differences. The present study is based on a need-fulfillment model, which places a major emphasis on individual differences in needs. A hierarchical clustering method was used to subgroup a sample of 570 managers on their need profiles. Need type was tested as a moderator of the relationship between specific dimensions of job satisfaction and overall job satisfaction. The findings showed that need type moderated the relative contributions of specific dimensions of satisfaction in the prediction of overall job satisfaction, and in addition the prediction level was found to be greater for the need types than for the total sample. 相似文献
