Structural models and occupational aspirations: Black-white variations among deep-south adolescents

Multivariate techniques for attribute data and the backward elimination procedure developed in regression analysis were utilized in an analysis of the occupational aspirations of deep-south adolescents. An examination of the models constructed revealed that: (1) social class indicators accounted for the largest effect estimates; (2) residence was associated with a smaller, yet statistically significant portion of the variation; and (3) the effect of race was negligible when controls were applied. Application of the most efficient model to black and white subsamples revealed race variations in both composite effect estimates and the rank order of effect estimates. Implications of these findings are discussed in terms of the developmental model of occupational choice and suggestions for further research are presented.     

Assessment of vocational maturity

A comparison is made between the Vocational Development Inventory and the Readiness for Career Planning scale when both were administered to the same sample. An analysis of covariance, with intelligence controlled for, indicated that both instruments show an over-all progression in vocational maturity at different grade levels, as well as differences between socioeconomic groups. A correlational matrix found vocational maturity scores from the two instruments to be significantly related.     

Instigation of assertive behavior through videotape-mediated assertive models and directed practice

Twenty-eight undergraduate college women received an assertive training procedure in which they observed videotape-mediated assertive models and practiced nine types of assertive responses over a seven-week period. They reported significantly (p< 0.01) more assertive behavior and were rated as significantly (p< 0.01) more assertive than subjects receiving a placebo treatment and subjects receiving no treatment. There were also trends (p's = 0.17, 0.19, 0.29) for Ss receiving assertive training to report lower fear of social conflicts than subjects under the two control conditions.     

The development of procedures for identifying competitive behavior in children

This study identified events in the competitive process that could be employed to discriminate between competition and individual, non-social behaviors. When children competed they overtly sought out information on how they were doing vis-à-vis their fellow competitor. In addition, their performance was a function of some competitive contingency: a reward for surpassing another. The procedures developed in this study were designed to manipulate competitive contingencies while observing their effects on task performance and social comparisons. The investigator could thus infer that competition was present when (1) subjects sought out information on how they were doing, as well as how another was doing on comparable tasks during competitive contingencies, and (2) their task performance was a function of the competitive contingency.     

Reinforcement and attraction specifying the effects of affective states

A multiplicative effect of magnitude and proportion of positive reinforcements on attraction and self-rated feelings was examined. Subjects (N = 270) rated their attraction toward persons associated with one of three reinforcement magnitudes (personality similarity, attitude similarity, and personal evaluations) and one of six proportions of positive reinforcements (.00, .20, .40, .60, .80, and 1.00). Results indicated that the slope of the linear attraction function increased and the Y-intercept decreased with increasing magnitude of reinforcement (p < .05). A similar interaction effect was found on the feelings of the subjects (N = 90) in another experiment. The results were interpreted as added support for Byrne's reinforcement-affect model of interpersonal attraction.     

Inducing ordinal and cardinal representations of the first five natural numbers

The prediction that the ordinal property of natural number symbols (using these symbols to represent the terms in an ordered progression) is more easily learned than the cardinal property of natural number symbols (using these symbols to represent the manyness of collections) was examined in this experiment. Preschoolers who evidenced no proficiency with either the ordinal or cardinal properties of natural number symbols were trained to acquire these properties via simple feedback. Both properties proved to be trainable. The most important findings were that the ordinal property was much easier to train than the cardinal property, ordinal training effects were more durable across a 1-week interval than cardinal training effects, and ordinal training appeared to transfer better than cardinal training.
