The study evaluates a test of occupational information administered to a national sample of 5000 young men, aged 14–24 in 1966, as part of the National Longitudinal Surveys of employment behavior. The predictive validity of the test score is assessed by reference to multiple regression analyses which confirm the significance of the score as an independent predictor of subsequent hourly earnings and occupational status. Correlation and factor analyses are used to examine the quality of the measurement instrument. All in all, the instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of difficulty. The test's reliability compares favorably with a commercially produced test designed to be used in counseling as a measure of occupational knowledge. With the possible modification of deleting a section relating to knowledge of earnings differentials, the test is commended to those involved in assessing and counseling the occupational choice process. 相似文献

In two experiments, rats acquired brightness discriminations in a free-operant circular runway with two response alternatives. Both individual and group choice times revealed continuous changes that were not apparent in the discrete measure of choice. Two major assumptions of Spence's discrimination learning theory were confirmed: (a) learning is continuous, and (b) discriminative stimuli in simple discrimination tasks of both simultaneous and successive types are compounds with position elements as well as elements from the relevant visual dimension. The distinctive, consistent pattern of learning revealed by the choice-time measure suggests that position habits reflect a learning strategy in which the complex task is learned as a series of simpler ones. 相似文献

The method of triads for psychophysical judgments was analyzed in terms of the unidimensional unfolding model of Coombs (1964). This model predicts laterality effects on the stochastic transitivity of triples for which existing models have been unable to account. An experiment was conducted in which triadic judgments were made on circles differing in area. The results confirmed the stochastic transitivity predictions, but a quantitative formulation of the model proved unsatisfactory. 相似文献

A central assumption in portfolio theory of risk preference is that for games with expected value constant the preference ordering of an individual should exhibit a single peaked preference function. This assumption was tested by determining the level of stochastic transitivity satisfied by triples of pairwise preference proportions among eight gambles. In only a small percentage of cases were the predicted levels of stochastic transitivity not satisfied. It was concluded that the results provided strong support for portfolio theory. 相似文献

The effects of a helper's physical attractiveness and role on help-seeking behavior were investigated here. Eighty randomly selected Smith College students were the subjects; the helpers were two confederates selected on the basis of a separately conducted photograph evaluation. The confederate was designated either as an experimenter (Role condition) or as a fellow subject (Nonrole condition). Subjects were reluctant to ask the attractive confederate for help when she was in the Nonrole condition; rather, most in this condition asked for information instead of assistance. When the confederate was unattractive, more subjects asked for help when she was in role than when she was not. Although there was a significant main effect, most of this effect appears to be accounted for by the low rate of seeking help in the Attractive, nonrole condition. Subjects took longer to communicate with the attractive confederate than with the unattractive one; further, they reported feeling more uncomfortable in the presence of the attractive helper regardless of role. 相似文献

The lever pressing of four food- and water-deprived rats was reinforced on concurrent variable-interval schedules. Food reinforced one response, and water reinforced the other. Response rates in baseline were higher in the food component than in the water component. After response patterns and body weights had stabilized, the animals were given access to either food only, water only, both food and water, or neither food nor water (baseline) before daily sessions. Giving food before a session decreased per cent time in the food component, decreased overall response rates for food, and increased overall response rates for water. Giving water before a session increased per cent time in the food component, increased overall response rates for food, and decreased overall response rates for water. Giving both food and water before a session resulted in a combination of prefeeding and prewatering effects. More food and more water were consumed when both were available than when only one was available before a session. 相似文献

Instruments, designed to assess values which affect the motivation to work and aspiration levels, were administered to over 600 Negro male seniors in Texas high schools. Results indicate that the degree and duration of school desegregation these students have experienced, ranging from less than 1 to more than 5 years, have had little effect on work values and occupational aspirations. 相似文献

Unassertive psychiatric patients matched on age, years of education, diagnosis, and self-reported assertiveness were assigned to one of five conditions, with 10 subjects in each group: (1) Test-Retest, (2) Practice-Control, (3) Instructions, (4) Modeling, (5) Modeling plus Instructions. All subjects were videotaped (Pre- and Post-Test) while responding to five interpersonal situations requiring assertive responses. Pre- and Post-Test responses for all subjects were rated independently by judges on seven verbal and non-verbal components of assertiveness. Analyses of variance for difference scores followed by multiple t-test comparisons indicated that the Modeling plus Instructions group was superior or equal to the Instructions alone or Modeling alone groups on five of the seven components. Instructions alone and Modeling alone led to greatest improvement in the remaining two components. No differences were found between the Practice-Control and Test-Retest groups on any of the seven components of assertiveness. No differences (Post-Pretest) were found among the groups on a self-report measure of assertiveness. 相似文献
