Change and continuity in neurobehavioral development: lessons from the study of neurobiology and neural plasticity

The goal of this paper is to discuss our current understanding of change and continuity in neurobehavioral development. After describing the basic elements of neurobiological development, attention is focused on the myriad of ways experience influences the developing and developed brain. This literature is used to illustrate the complexity of both brain and behavioral development in the context of change and continuity. The implications of considering brain/behavior relations in the context of development comprise the final section of the paper.     

The Stress of Organisational Change: A Dynamic Process Model

Plongées dans un marché mondial, les organisations ne cessent de subir de profonds changements. Encore que la plupart de ces changements soient nécessaires et souvent retardés, ils présentent comme inconvénient le risque de coûts élevés en terme d'accroissement des dépenses de santé, de pertes de productivité, de baisse de la satisfaction professionnelle et de chute du moral. Ces coûts peuvent être directement imputés à la détresse qui frappe les salariés d'une organisation confrontée à des changement permanents. Cet article propose un modèle dynamique permettant d'aborder les articulations complexes entre le changement organisationnel et le stress subi par les individus. A partir de ce modèle, des interventions prenant en compte tous les aspects du problème pourront être conçues pour aider les salariés à gérer le stress provoqué par les mutations des organisations.
Organisations in the global marketplace continue to experience tremendous change. Although most of these changes are necessary and long overdue, the downside includes the risk of huge costs in terms of increased health care expenses, lost productivity, lower levels of job satisfaction, and low morale. These costs may be directly attributed to the distress that is created when an organisation's employees encounter constant changes. This paper establishes a dynamic framework from which we can begin to understand the complex interplay between change at the organisational level and stress at the individual level. Using this framework, comprehensive interventions can ultimately be developed to help employees manage the stress of organisational transitions.     

Time Series Analysis in Historiometry: A Comment on Simonton

Time series analysis (TSA) is one of a number of new methods of data analysis appropriate for longitudinal data. Simonton (1998) applied TSA to an analysis of the causal relationship between two types of stress and both the physical and mental health of George III. This innovative application demonstrates both the strengths and weaknesses of time series analysis. Time series is applicable to a unique class of problems, can use information about temporal ordering to make statements about causation, and focuses on patterns of change over time, all strengths of the Simonton study. Time series analysis also suffers from a number of weaknesses, including problems with generalization from a single study, difficulty in obtaining appropriate measures, and problems with accurately identifying the correct model to represent the data. While careful attempts are made to minimize these problems, each is present in the Simonton study, although sometimes in a subtle manner. Changes in how the data could be gathered are suggested that might help to solve some of these problems in future studies. Finally, the advantages and disadvantages of employing alternative methods for analyzing multivariate time series data, including dynamic factor analysis, are discussed.     

Depressive Attributional Style: The Role of Self-Esteem

Two studies evaluate the role of self-esteem in the depressive attributional style. In the first study, college students completed four measures of depression, four measures of self-esteem, and the Attributional Style Questionnaire (ASQ). Regression analyses revealed that across measures, self-esteem was a better predictor of attributional style for negative events than was depression. In study two, psychiatric inpatients completed a measure of self-esteem, a measure of depression, and the ASQ. In this clinical sample, self-esteem and depression were highly correlated and both predicted ASQ scores. But when variation in depth of depression and social desirability were removed statistically from the association between self-esteem and attributions for negative outcomes, there remained a significant association between self-esteem and internal, stable, and global attributions for negative outcomes. Controlling for the variation in self-esteem eliminated the relation between depression and depressive attributional style. These findings demonstrate the importance of self-esteem in depressive attributional style in both normal and clinical populations, as well as potential differences in the relations among self-esteem, depression, and attributional style in clinical versus normal samples.     

The role of contextual variables in maternal reactions to children's compliance and noncompliance

The present study was designed to assess whether certain contexts influenced material reactions to children's compliant and noncompliant behavior. Study 1 examined the following contextual variables: chronic negative conditions of the child (physical illness and psychological disturbance) and recent life events experienced by the child (both positive and negative). Study 2 examined maternal mood states as another contextual variable. Results indicated that these contexts relate to differential choices of discipline techniques, based on maternal self-report. These data are examined in light of the literature on treatment acceptability and are discussed in terms of a signal-detection model. Clinical applications are addressed, and suggestions for future research are offered.Portions of this paper were presented at the meeting of the Association for Advancement of Behavior Therapy, Philadelphia, November 1984.We express gratitude to the Research Council of the University of North Carolina at Greensboro for Research Council Grant 2110 218 00000 7719 and to the following for their assistance: James Herbert, Nancy Quinn, Carol Roberson, Ira Turkat, and Marilyn Williams.     

Evaluation of a social problem-solving skills program for third- and fourth-grade students

The effects of a social problem-solving (SPS) training program for entire classrooms of third- and fourth-grade children were examined in two studies. In the first study, experimental children showed significantly greater improvement in knowledge and performance of SPS skills than control children. However, both positive and negative effects of the intervention (varying by classroom) were found on measures of behavioral adjustment, self-efficacy, and peer acceptance at a 6-month follow-up. The second study compared two different intervention strategies: (a) SPS training with teacher-student dialoguing, peer pairing, and self-monitoring, and (b) SPS training with dialoguing only. It was found that children in both the experimental and control groups improved significantly in performance of SPS skills but no differences between the groups were found for changes in behavioral adjustment, self-efficacy, and peer acceptance. The limitations of cognitively mediated interventions for young children were discussed.     

Testing Models of Turnover Intentions with University Faculty1

Four models of turnover intentions were competitively tested for their effectiveness in predicting the intentions to search for alternative positions and intentions to resign from current positions among a sample of university faculty. Faculty at an upper Midwest university completed a survey developed to measure the components of the four models. All four models (intermediate linkages, expanded Mobley, reasoned action, and planned behavior) significantly predicted intentions to search and intentions to resign. The reasoned action model was found to be more effective and parsimonious than the other models. Attitude toward the turnover action and subjective norm concerning the turnover action appear to be the critical factors influencing the faculty members' turnover intentions. Implications of these findings for turnover research and related concepts such as organizational commitment are discussed.     

The influence of near-threshold priming on metamemory and recall

A metamemory paradigm involving the use of near-threshold visual priming is developed in which a brief flash of a previously nonrecalled answer occurs, and then the person attempts to recall the answer and/or make feeling-of-knowing judgments. The major new finding is that the feeling of knowing did not detect perceptual input from a near-threshold prime that increased the recall of otherwise nonrecallable items. This finding has two important implications: (1) The feeling of knowing is not always more sensitive than recall as an indicant of information in memory (particularly, as an indicant of small amounts of information newly deposited into memory), and (2) 'monitored' information (that the feeling of knowing would be capable of detecting, as examined in previous research) can be combined with 'nonmonitored' information (that is newly deposited into memory and that the feeling of knowing does not detect) so as to produce the successful recall of an otherwise nonrecallable item.
