A self-efficacy approach to the career development of women

An approach to the conceptualization and facilitation of women's career development based on Bandura, 1977, Bandura, 1977, 84, 191–215) self-efficacy theory is presented. The model presented postulates that largely as a result of socialization experiences, women lack strong expectations of personal efficacy in relationship to many career-related behaviors and, thus, fail to fully realize their capabilities and talents in career pursuits. Sex differences in the access to and availability of four sources of information important to the development of strong expectations of personal efficacy are reviewed and discussed in relationship to women's career decisions and achievements. The utility of the proposed model for integrating existing knowledge of women's career development, for generating productive avenues of inquiry, and for guiding intervention efforts is discussed. The conceptual framework provided is seen as having implications for the career development of men as well as women, but the focus herein is on its potential for contributing to knowledge of the career development of women.     

Disfluent speech associated with brain damage

The frequency and type of disfluencies in the spontaneous speech of 15 people with Broca's aphasia and right hemiplegia was studied. Two aged-matched control groups (15 nonaphasic stroke patients with left hemiplegia and 15 normals) were also studied. The frequency of disfluencies in the speech of aphasics was three times greater than that in the speech of either control group. However, most of the disfluencies uttered by aphasics were of the types commonly found in speech of normals.     

Vocal and nonvocal discriminative performance in monkeys

Discriminative performance of a lever press and a vocal call was compared in five macaques. The animals exhibited similar scores for Response Rate, Efficiency, and Error Index. Total vocal responses were slightly higher than total lever responses. Latency for vocal responses was significantly greater than lever press. Similar scores in measures of performance of the two behaviors indicate that discriminative vocalization is not exceedingly difficult. Failure by others to achieve discriminative vocalization in studies employing weak positive-reinforcement contingencies suggest that certain experimental paradigms are unsatisfactory for vocal conditioning.     

Nontransitive measurable utility

A new theory of preferences under risk is presented that does not use the transitivity and independence axioms of the von Neumann-Morgenstern linear utility theory. Utilities in the new theory are unique up to a similarity transformation (ratio scale measurement). They key to this generalization of the traditional linear theory lies in its representation of binary preferences by a bivariate rather than univariate real valued function. Linear theory obtains a linear function u on a set P of probability measures for which u(p) > u(q) if and only if p is preferred to q. The new theory obtains a skew-symmetric bilinear function φ on P × P for which φ(p, q) > 0 if and only if p is preferred to q. Continuity, dominance, and symmetry axioms are shown to be necessary and sufficient for the new representation.     

Intersensory substitution in the blind

This study looks at the implications for theories of development of an intersensory surrogate for the blind—the Sonicguide. Results of both short- and longterm studies suggest that there is a critical age, before which use of the Sonicguide is qualitatively more effective than attempts at intervention begun after this age. Similarly the young infants in the sample show a much more rapid acquisition of ability to use the guide effectively. The importance of such results for theories of perceptual development is discussed.     

A mental-health locus of control scale

The purpose of this study was to develop and seek initial validation of a mental- health locus of control scale. Twenty-six mental-health professionals rated each of the 14 statements of a previously-designed mental-health service request form along a 5-point locus of control scale. Six of the 14 items met the study's criteria for inclusion in the mental-health locus of control scale. Discriminant validity of the scale was provided by a study demonstrating that psychotic patients were more external in their perceived locus of control than were a nonpsychotic patient comparison group. Other validation studies and research are suggested.     

Holland's theory and non-college-degreed working men and women

The main concern of this study was to investigate differences between men and women employed in traditional male occupations using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 103 male and female non-college-degreed workers in three occupations (bus-taxi drivers, police officers, and car sales agents) corresponding to three of Holland's environmental categories (Realistic, Social, and Enterprising). In general, the results indicate that the VPI and SDS scales to some extent discriminate among occupational groups, but expected patterns do not always occur within and between occupational groups.     

Influence of stuttering therapy on clinicians'' disfluencies: Effects of client modeling

This study investigated whether student clinicians working with stutterers subsequently produce more disfluencies than student clinicians providing therapy to clients with other speech and language disorders. Seventeen graduate students working in a 6-wk summer camp setting were divided into two groups: eight who provided treatment for stutterers (group 1) and nine who provided therapy for clients with other communication disorders (group 2). All student clinicians were recorded during spontaneous speaking and oral reading tasks prior to camper arrival and following camper departure. An eight-category classification system was used to determine disfluency types. Findings revealed that Group 1 clinicians significantly decreased their total disfluencies between pre- and post-camp recordings on the spontaneous speaking task. Unexpectedly, this same group also substantially increased part-word repetitions and sound prolongations. The possibilities of incidental learning, reverse modeling, and overidentification with stuttering clients are discussed.
