A SOCIAL ECOLOGY OF HYPERACTIVE BOYS: MEDICATION EFFECTS IN STRUCTURED CLASSROOM ENVIRONMENTS

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies.     

DEC users’ group report

DEC users discussed ways to improve communications among users, including the initiation of a newsletter. Also, new products of special interest to psychologists were described by the DEC representative present at the meeting.     

Process Dissociation Procedure: Double Dissociations Following Divided Attention and Speeded Responding

The validity of the process dissociation procedure was examined by manipulating attention and speed of responding in a recognition task. Both manipulations were expected to decrease the probability of controlled memory processes, c, while leaving the probability of automatic memory processes, a, unaffected. In order to estimate c and a, a multinomial processing tree modelwas fittedto the data.Contrary to expectation, a double dissociation (i.e.a decrease inc coupled with an increase in a) was obtained, suggesting that a does not accurately measure the probability of automatic processes. The results are discussed with reference to the independence assumption in the process dissociation procedure.     

Computer use by the visually impaired

Several recent developments have made computers accessible to the blind and partially sighted: hard-copy (paper) and softcopy (raised-pin) braille output, magnified high-resolution characters, and synthetic speech. We report survey data on these users’ computer education, tasks, and goals; their hardware uses and preferences, particularly for special-purpose I/O devices; and seven classes of human-factors problems that affect the use of these I/O devices by the visually impaired.     

A State-Trait Analysis of Job Satisfaction: On the Effect of Core Self-Evaluations

Une recherche récente qui portait sur les fondements caractériels de la satisfaction au travail s’est focalisée sur le rapport entre la satisfaction professionnelle observée et le noyau central des autoévaluations (CSE). Cette étude s’est occupée d’une part de la relation entre la variance‐trait de la satisfaction au travail et le CSE et d’autre part de la structure des variables CSE. En faisant le choix d’un modèle de mesure longitudinal, nous avons d’abord recherché si le CSE était suffisamment stable, cela à partir d’une analyse secondaire de quatre périodes successives. Les résultats montrent une forte stabilité du CSE (.87 sur deux ans). Nous avons ensuite opéré une scission état‐trait de la satisfaction professionnelle de façon à dissocier la variance‐trait de la satisfaction au travail de la variance instable. Le facteur stable de satisfaction professionnelle fut mis en rapport, par régression, avec les variables CSE, en utilisant plusieurs modèles de CSE (une sommation, un facteur latent ou un concept global). D’après les résultats, il vaut mieux traiter les variables CSE comme une sommation, et cette série rend compte de presque toute la variance stable de la satisfaction professionnelle (84%). En outre, seuls l’affectivité négative et le locus of control interne avaient un impact significatif, alors que l’estime de soi et l’efficience personnelle n’en avaient pas. On conclut que la conception actuelle du CSE comme concept supraordonné englobant quatre dimensions est défendable, mais trop générale pour les recherches sur la satisfaction professionnelle; il est plus satisfaisant et suffisant d’analyser à la fois l’affectivité négative et le locus of control. Recent research that looked into the dispositional base of job satisfaction focused on relating observed job satisfaction to core self‐evaluations (CSE). This study was concerned with (a) the relation between the trait variance of job satisfaction and CSE and (b) the structure of the CSE‐variables. Using a longitudinal measurement model in a secondary analysis of four waves of a longitudinal study we first tested whether CSE are sufficiently stable over time. Results indicate a high stability of CSE (.87 across 2 years). We then performed a state‐trait decomposition of job satisfaction in order to separate trait variance of job satisfaction from changing variance. The stable job satisfaction factor was regressed on CSE‐variables, using different models of CSE (a collective set, a latent factor, or an aggregate concept). Results were in favor of treating the CSE‐variables as a collective set, and this set explained almost all stable variance of job satisfaction (84%). Moreover, only negative affectivity and internal locus of control had a significant impact, whereas self‐esteem and self‐efficacy had not. It is concluded that current conceptualisations of CSE as a superordinate concept underlying its four dimensions is possible but overly broad in job satisfaction research; collective consideration of LOC and NA is better and sufficient.     

EDUCATING ABOUT WOMEN AND GENDER

This study assesses the multiple effects of planned exposure to gender and women's issues on graduate student development. Students in a gender-aware Counseling Psychology program (n = 63) were compared to those in two other graduate psychology programs (total n = 38) on five scales that measured exposure to gender issues, social constructivist views, feminist identity development, performance self-esteem, and endorsement of feminist therapy goals and strategies. Results supported the hypotheses that all outcome measures were significantly correlated with the extent of academic experiences related to women and gender. Program of concentration and level of graduate training were differentially related to social construction views and stages of feminist identity development. We discuss these findings in terms of their implications for gender-aware education in the development of student identity, attitudes, and professional practice.     

Job satisfaction related to tested congruence and differentiation

Tested personality-environment congruence and differentiation, singly and in combination, as measured by the Vocational Preference Inventory (J. L. Holland, Palo Alto, California, Consulting Psychologists Press, 1977b), were predictive of reported job satisfaction for teachers employed in five subject matter areas. Time-related variables and sex were not significantly related to the job satisfaction measure used in the study.
