Cotherapy treatment of phobias: A case study

A case study is presented of the treatment of a woman who had suffered from claustrophobia for over 13 years, by cotherapists using a combination of desensitization and flooding techniques. By assuming specific roles, the therapists expedited the therapeutic process to a successful conclusion in a brief period of time.     

Partial visual feedback and spatial end-point accuracy of discrete aiming movements

Five experiments are reported in which the effect of partial visual feedback on the accuracy of discrete target aiming was investigated. Visual feedback was manipulated through a spectacle-mounted liquid-crystal tachistoscope. The length of the visual feedback interval was varied as a percentage of the instructed movement time. In Experiment 1, the length of the vision interval was manipulated symmetrically at the beginning- and end-phase of the movement, whereas in the remaining experiments, the vision time was varied with respect to the end-phase only. The variations at the end were examined for different distances (Experiment 2), different movement speeds at the same distance (Experiment 3), and in small interstep intervals (Experiment 4). A vision time of more than 150 ms at the end-phase of the movement enhanced aiming performance in all experiments. Longer vision times monotonously improved aiming accuracy; the fifth experiment showed that a vision time of about 275 ms was sufficient for near-perfect aiming. Furthermore, the significance of vision during the first phase of a movement was demonstrated again. The results of the five experiments pointed to shorter visuomotor processing times. To explain the beneficial effects of short vision times for aiming accuracy, we propose a model of visuomotor processing that is based on the stochastic optimized submovement model of Meyer, Abrams, Kornblum, Wright, and Smith (1988).     

Motor skill acquisition and retention as a function of average feedback, summary feedback, and performance variability

Summary feedback involves withholding feedback from subjects until the last trial in a block is completed, and then presenting feedback about each trial. A variation of this method, called average feedback (Young & Schmidt, 1992), presents subjects with only the mean of the trial block. We investigated whether these methods have similar effects on acquisition and retention of a simple motor skill. Five groups of subjects (n = 16 per group) performed 60 acquisition trials of an aiming task involving both spatial and temporal accuracy. We presented average and summary feedback based on either 5-trial blocks or 15-trial blocks and compared these schedules with every-trial feedback. During acquisition, all groups improved with practice, with a slight tendency for the every-trial condition to have less absolute error than the longer summary and average conditions. Analysis of delayed no-feedback retention tests, however, revealed a strong advantage for the 5-trial summary and average conditions compared with the every-trial condition. In addition, we found that for long blocks of acquisition trials without augmented feedback, the performance variability of those trials was associated with retention performance. Results are discussed in terms of how these different manipulations may make feedback less useful during acquisition, but foster the use of certain information processing activities that enhance overall learning.     

One Personality, Multiple Selves: Integrating Personality and Social Roles

ABSTRACT How do people maintain multiple, role-specific self-conceptions as well as a consistent sense of self? In a sample of middle-aged women, we examined three issues: (a) the ways in which people view themselves as both different and similar across social roles (e.g., parent, friend, worker), (b) how role-specific self-conceptions and general self-conceptions are related, and (c) the merits of predicting role-specific criteria from role-specific and general self-conceptions. Results showed that subjects' self-conceptions were specific to role contexts, yet highly correlated across those same role contexts. In addition, role-specific self-conceptions were more similar to the general self-concept for roles with which the individual was more satisfied. Finally, as predicted from the bandwidth-fidelity trade-off, ratings of the general self correlated moderately with outcomes across all role domains, whereas ratings of role-specific self-conceptions correlated strongly with outcomes for the same role, but not in other roles.     

Activation of response codes by relevant and irrelevant stimulus information

Single-route models attribute stimulus-response compatibility effects to the difficulty of translation from stimulus to response. Dual-route models propose that compatibility effects reflect in part an additional direct, or automatic, activation route. Selected findings from three lines of research are reported that converge to provide evidence consistent with the view that the automatic activation route plays a role in compatibility effects. The data suggest that the activation produced via this route by relevant stimulus attributes influences response selection only when all mappings of stimuli to responses are known to be compatible.     

CAN MULTI-SOURCE FEEDBACK CHANGE PERCEPTIONS OF GOAL ACCOMPLISHMENT,SELF-EVALUATIONS,AND PERFORMANCE-RELATED OUTCOMES? THEORY-BASED APPLICATIONS AND DIRECTIONS FOR RESEARCH

Multi-source feedback extends traditional performance appraisal by collecting information from subordinates, peers, supervisors, and customers. Ratees often receive the results along with normative data and self-ratings. This paper explores how multi-source feedback goes beyond traditional performance appraisal by providing ratees with comparative information. Focusing on person perception and information processing dynamics, this paper develops a model and associated propositions to explain the effects of multi-source feedback on perceptions of goal accomplishment, re-evaluation of self-image, and changes in outcomes such as goals, development, behavior, and performance. Moderators of relationships between the major components in the model include individual difference variables (self-image, feedback seeking, self-monitoring, task-specific self-efficacy, and impression management) and situational conditions (the content and process of multi-source feedback and organizational performance standards). Issues of research and practice intended to improve understanding and effectiveness of multi-source feedback are discussed.     

AN EMPIRICAL INVESTIGATION OF THE PREDICTORS OF EXECUTIVE CAREER SUCCESS

This study examined the degree to which demographic, human capital, motivational, organizational, and industrylregion variables predicted executive career success. Career success was assumed to comprise objective (pay, ascendancy) and subjective (job satisfaction, career satisfaction) elements. Results obtained from a sample of 1,388 U.S. executives suggested that demographic, human capital, motivational, and organizational variables explained significant variance in objective career success and in career satisfaction. Particularly interesting were findings that educational level, quality, prestige, and degree type all predicted financial success. In contrast, only the motivational and organizational variables explained significant amounts of variance in job satisfaction. These findings suggest that the variables that lead to objective career success often are quite different from those that lead to subjectively defined success.     

Towards a Hierarchical Model of Self-concept for Hong Kong Chinese Adults with Physical Disabilities

This paper explores the basic facets and structure of the self-concepts of groups of 135 and 146 Hong Kong Chinese adults with and without physical disabilities, respectively. Comparison of responses to a 20-item scale indicated a very similar pattern of the importance the individuals in these groups attached to these areas of their lives. However, the non-disabled group did report higher satisfaction ratings on six of these areas and factor analysis of both the importance and satisfaction ratings showed a similar underlying factor structure for both groups. Content analysis of open-ended questions confirmed that both groups shared similar self-concept facets except that the subjects with physical disabilities most frequently reported the importance of “functional independence in daily living tasks”. It is proposed that this facet needs to be included in a self-concept instrument appropriate for subjects with physical disabilities. Models of self-concept were then suggested for each group.
