Piaget's theory of space perception in infancy.

Piaget's theory of space perception in infancy is presented in the format of a hypothetico-deductive system. Eleven hypotheses are defined, regarding the perception of the agent of visual change; shape and size constancy; depth; and the perception of higher-order relationships among spatial elements. The proof Piaget offers for each hypothesis is presented in the following steps: behavioral evidence, interpretation in terms of inner states; inferences and generalizations. Presuppositions underlying the arguments are explicated. Critical notes are inserted whenever appropriate. Some general conclusions are briefly discussed.     

A component model for diagnosing and treating children who stutter

Nine components of stuttering and their distribution among 54 children who stutter are described. The components are arranged into a model that includes four neurologic components (attending disorder, auditory-processing disorder, sentence-formulation disorder, and oral-motor disorder) and five traditional components (high self-expectations, manipulative stuttering, disruptive communication environment, unrealistic parental expectations, and abnormal parental need for the child to stutter). Diagnostic and treatment usefulness of the model are discussed. Thirty-two of the children have been followed through component-based treatment and 12 mo post termination. Results indicate that treatment was successful with 27 (84%) of the 32 children. Only one child regressed during the 12 mo after treatment ended. These results suggest that treating the neurologic and traditional factors which disrupt fluency improves maintenance and carry-over.     

Anxiety, learning, and memory: A reconceptualization

A new theoretical framework for work on anxiety and memory is proposed. Anxious subjects engage in task-irrelevant processing which preempts processing resources and some of the available capacity of working memory. They typically attempt to compensate for the adverse effects of this task-irrelevent processing on task performance by increased effort. It follows from these theoretical assumptions that anxiety will have differential effects on performance efficiency (i.e., the quality of performance) and on processing effectiveness (i.e., performance efficiency/effort). Anxiety will always reduce processing effectiveness, but will not impair performance efficiency if there is sufficient effort expenditure. Consequently, reliance on measures of performance efficiency will often obscure the detrimental effects of anxiety on processing effectiveness.     

Impacts of role perceptions on organizational commitment,job involvement,and psychosomatic illness among three vocational groupings

This study involved an attempt to assess the comparative influences of perceived role conflict and role ambiguity on psychological investments in work roles (organizational commitment and job involvement) and on work-related psychosomatic illness. In addition, these influences were assessed within a cross-vocational framework in order to determine how obtained relationships may have differed across work roles based on three widely differing vocational groupings. Results indicate that the comparative influences of these two role perceptions differ with respect to the outcomes in question and with respect to differences in the complexity of work roles.     

Perceived causality for success in occupations

A representative group of occupations was examined within an attributional framework, utilizing the concept of perceived causality for success. Specifically, it was hypothesized that (1) success in different types of occupations would be attributed to different causes, (2) the causal attributions of incumbents would differ from those of nonincumbents, (3) standard occupational categories could be derived on the basis of perceived causality for success, and (4) perceived causality for success could be used as a basis for generating a circular ordering of occupations.Holland's (1973) occupational classification was used as a basis for categorization. College students, as well as six types of occupational incumbents, were administered a questionnaire in which they attributed causality for success in 35 occupations. The results supported the first three hypotheses and also revealed some systematic relationships between causes and between perceived causality for success and occupational prestige.     

Career commitment processes in the young adult years: An illustration from the ROTC/Army career path

This paper presents and tests a model of career commitment in the young adult years. Data for the study were collected from nationwide stratified random samples of approximately 1000 high school seniors, 1600 college students, and 600 ROTC-graduate Army officers. It was found that the model could predict membership in ROTC and the strength of the individual's commitment to a military career and that hypotheses that had been made about the career commitment process were generally confirmed. Many of the specific findings, differences in the demographic, aptitude, and sociopsychological profile of participants and nonparticipants in a career path, the widening of these differences with the passage of time, the importance of early exposure to the career eventually chosen, the relationship between initial motivation in exploring a career path and subsequent commitment to the career, and the changes in the nature of influential factors as an individual matures, may be generalizable to other types of careers.     

Sequencing of vocational development stages: Further studies

This paper reports two studies which support the prediction derived from Hershenson's (Journal of Counseling Psychology, 1968, 15, 23–30) life-stage vocational development model that average scores on Self-differentiation (worker self-concept and motivation) would exceed those on Competence (work habits, skills, and interpersonal relations), which in turn would exceed those on Independence (appropriateness and crystallization of vocational goals). The first study involved ratings by project staff on an inner city, socially disadvantaged population, and the second study involved self-ratings by individuals who had changed occupations in midcareer. Findings are consistent with those reported by Hershenson and Langbauer (Journal of Counseling Psychology, 1973, 20, 519–521) on a population of deaf clients.     

Androgyny and traditional versus nontraditional major choice among college freshmen

The present study investigated the relationship of psychological androgyny to career choice among college freshmen. Women in home economics and engineering and men in engineering (N = 231) completed the Bem Sex-Role Inventory and rating scales of satisfaction with and certainty of college major and intended occupation. As a group, women in engineering scored in a more androgynous direction than did either men in engineering or women in home economics. Among sex-typed subjects, more women in engineering scored in a masculine sex-typed category than did women in home economics. Men and women in engineering did not differ on satisfaction and certainty ratings of major or career; however, feminine-typed women were significantly less satisfied with and tended to be less certain of their choice of major than other women in engineering.     

Self-instructions as discriminative cues for rule-breaking or rule-following

This experiment examined the relationship between self-instructions and subsequent instruction-following performance, as a function of the history of the consequences for correspondence or noncorrespondence. Subjects were two groups of elementary school children (ages 7 and 8 years). In training, the two groups were exposed to different histories of congruence or noncongruence between self-instructions and consequences for performance. In the Congruent group, subjects were exposed to a series of stimuli to which they were trained to give self-instructions to make, or not to make, a key-pressing response. Reinforcement was given for self-instructing, and responding in accord with the self-instruction. Subjects in the Noncongruent group were trained to give the same self-instructions for the same stimuli, but reinforcement was given for counter-compliance. Subsequently, in a temptation situation, the experimenter gave an instruction not to press for a test stimulus; and subjects were trained to give the inhibitory self-instruction for this stimulus. Subjects in the Noncongruent group showed a high rate of rule-breaking. The effects on behavior of self-delivered instructions depend on the past relations between these events and the consequences for instruction-following. Implications are discussed for moral behavior and cognitively oriented therapy.
