Effects of schedule and magnitude of reinforcement under conditions of thirst motivation

In contrast to a recent finding (Macdonald, G. E., & De Toledo, L. Learning and Motivation, 1974, 5, 288–298.) the results of three experiments investigating various partial reinforcement (PRF) manipulations under conditions of thirst motivation demonstrated strong similarity to analogous manipulations involving food reward. Specifically, for animals receiving water reinforcement, PRF was shown to generate greater resistance to extinction than continuous reinforcement (Expt 1 & 3), the schedule of reinforcement was shown to interact with level of acquisition (Expt 1 and 2), and the magnitude of the partial reinforcement extinction effect was shown to be a function of reward magnitude (Expt 3). These results provide strong evidence that mechanisms which operate in partial reinforcement situations are highly similar, regardless of the type of appetitive reinforcement.     

2001 DIVISION 27 PRESIDENTIAL ADDRESS: Emotional Intelligence and the Good Community

Suggests various ways in which the concept of emotional intelligence (EI) can inform community research and action. Begins by defining EI and reviewing the growing body of research on its contribution to educational, health, and occupational outcomes. Next distinguishes between EI and the related concept of emotional and social competence. Then considers the connection between EI and several topics of interest to community action researchers including prevention and wellness promotion, implementation and dissemination of innovative programs, community development, and the value of diversity. Concludes by suggesting that the ecological perspective can help inform research and practice relating to EI.     

Managerial Stress, Locus of Control, and Job Strain in Taiwan and UK: A Comparative Study

This study investigated managerial stress in Taiwan and UK using the Occupational Stress Indicator-2 (OSI-2) and the Work Locus of Control (WLCS) scale. Results showed that the reliability and validity of the measures used were acceptable and comparable in the two samples. There were similarities as well as differences in managerial stress in the two countries. Recognition and Managerial role were important predictors of strain for the Chinese managers, whereas Relationships, Organizational climate, and Personal responsibility were important predictors of strain for UK managers. There were consistent moderating (vulnerability) effects of internal control for the Taiwanese managers. Results corroborated some previous studies conducted in the West. However, caution was also suggested for generalizing Western-originated concepts and theories across cultural boundaries.     

Judging distance across texture discontinuities

Sinai et al (1998 Nature 395 497-500) showed that less distance is perceived along a ground surface that spans two differently textured regions than along a surface that is uniformly textured. We examined the effect of texture continuity on judged distance using computer-generated displays of simulated surfaces in five experiments. Discontinuities were produced by using different textures, the same texture reversed in contrast, or the same texture shifted horizontally. The simulated surface was either a ground plane or a frontoparallel plane. For all textures and both orientations, less distance was judged in the discontinuous conditions than in continuous conditions. We propose that when a surface contains a texture discontinuity, a small area adjacent to the perceived boundary is excluded from judged distances.     

Distributing working memory resources during problem solving

This study examines how problem solvers distribute working memory demands over internal and external resources. Participants recorded notes while performing an arithmetic task. They recorded a majority of intermediate results and labeled many of those results (e.g., "C = 10"). When more effort was required to take notes, participants recorded fewer results. Participants with a consistent goal structure recorded fewer results and with practice labeled fewer recorded results than those with varied goal structures. When notes were displayed in a consistent spatial arrangement participants labeled fewer recorded results than when notes appeared in varied locations. These findings indicate that individuals use explicit and implicit strategies for indexing intermediate results. The data support the view that individuals flexibly distribute working memory over internal and external resources in response to situational cost-benefit considerations.     

The effects of distractors in multiple object tracking are modulated by the similarity of distractor and target features

Is the effect of distractors in multiple object tracking dependent on the distractors sharing the features of the targets? In experiment 1, observers tracked five targets among five distractors that were identical to the targets and a number of additional distractors that were either identical to or featurally distinct from the targets. Results showed that distractors that are distinct from the targets in shape or color, or are stationary, impair tracking less than distractors that are identical to the targets. However, tracking performance declined as the number of distractors increased, even for featurally distinct distractors. Experiment 2 showed that distractors that differ from the targets on two features impair tracking less than distractors that differ from the targets on only one feature, but only when target tracking load is low. These results indicate that shape, color, and motion information about distractors can be used to distinguish them from targets during tracking, although even distractors with a different feature from the targets produce some interference with tracking. These findings suggest that the effect of distractors on tracking is dependent on top-down settings for target features.     

The relationship between motivation and achievement in interdependent situations

This meta‐analysis investigates the degree to which achievement is positively associated with motivation within situations characterized by positive, negative, and no interdependence. First, the relative effects of positive, negative, and no interdependence on motivation and achievement were determined. Then the amount of variance in achievement explained by motivation (and vice versa) was calculated. In all, 629 independent studies were included, representing 26 different countries. Results also showed that motivation accounted for 14% of the variance in achievement (and vice versa). When the lowest‐quality studies were eliminated, the percentage of achievement explained by motivation increased to 24%. Positive interdependence resulted in greater motivation and achievement than did negative or no interdependence. Implications for theory and application are discussed.     

Testing an integrated model of the work–family interface in Chinese employees: A longitudinal study

The purpose of this study was to examine an integrated model of the work–family interface (WFI) linking work–family demands (workload and family conflict), resources (supervisory support and family support) and role satisfaction in a Chinese context. The four‐factor structure of WFI comprises direction of influence (work to family vs family to work) and types of effect (work–family conflict vs work–family enrichment). A longitudinal design was used to collect data from 409 Chinese employees at three time points, separating measures of antecedents (T1), WFI (T2) and outcomes (T3) in time. The results based on structural equation modelling (SEM) reveal that: (1) the direction and types of effect were two underlying dimensions of the WFI, supporting the four‐factor structure; (2) demands were more strongly related to conflict, while resources were more strongly related to enrichment; (3) work–family conflict and enrichment were related to role satisfaction, regardless of the direction of influence.     

Gender Differences in Adolescent Self-Esteem: An Exploration of Domains

The relationship between gender and global self-esteem in adolescence, while modest, has been well established, with boys consistently scoring higher than girls. In the present study, we sought to understand gender differences in adolescent self-esteem in terms of its component parts. With a relatively large (n = 545) sample of adolescents, drawn from Grades 8, 10. and 12, we specified 8 domains of adolescent self-esteem (personal security, home/parents, peer popularity, academic competence, attractiveness, personal mastery, psychological permeability, and athletic competence) across a number of different instruments and brought them together into a common assessment superstructure. Gender differences as well as the relative contributions of the different domains to overall self-esteem scores were measured. As predicted, boys attained slightly higher global self-esteem scores than girls did, by a difference of .22 standard deviation units. Contrary to our expectation of more balanced domain effects, boys significantly outperformed girls in 6 of 8 domains, whereas the 2 remaining domains exhibited no significant gender differences. There were no main or interaction effects for grade level. In terms of relative contribution of these domains to global self-esteem for the 2 genders, global self-esteem in boys and girls is predicted in very similar strengths and in the same order of magnitude by identical domains of self-esteem: home/parents, personal security, academic competence, attractiveness, and personal mastery—yielding multiple R ²s from .88 to .91.     

Managerial Stress in Greater China: The Direct and Moderator Effects of Coping Strategies and Work Locus of Control

La présente étude examine les effets directs et modérateurs des stratégies de défense (contrôle et support) et de la perception de contrôle au travail (extérieure) sur des relations stresseur-tension entre des gestionnaires de la grande Chine (la République populaire de Chine, Hong Kong, et Taiwan). Les données ont été recueillies, via un questionnaire autoadministré, auprès de 876 gestionnaires soit 249 (164 hommes, 85 femmes) en République populaire de Chine, 280 à Hong Kong (159 hommes, 120 femmes, 1 non classifié), et 347 (191 hommes, 151 femmes, 5 non classifiés) au Taiwan. Des effets directs et modérateurs pour les stratégies de défense et pour la perception de contrôle ont été démontrés pour quelques relations stresseur-tension dans les divers échantillons étudiés.
The present study aims at examining the direct and moderator effects of coping strategies (control and support coping) and work locus of control (externality) on the stressor-strain relationships among managers in Greater China (the People's Republic of China [PRC], Hong Kong, and Taiwan). A self-administered survey method was employed to collect data from 249 (164 male, 85 female) managers in the PRC, 280 (159 male, 120 female, 1 unclassified) managers in Hong Kong, and 347 (191 male, 151 female, 5 unclassified) managers in Taiwan. The direct and moderator effects of control coping, support coping, and work locus of control on some stressor-strain relationships were demonstrated in the studied samples.
