Response of the pituitary-adrenal axis in terms of type a behaviour,hostility and vital exhaustion in healthy middle-aged men

Abstract

Pituitary-adrenal axis was studied in terms of Type A behaviour, hostility and vital exhaustion among 69 healthy middle-aged men. The results showed that psychological factors could explain a significant proportion of the biologically manipulated responses of HPA axis, but they worked in different ways. Type A behaviour was related to a high level of mean basal ACTH and a low level of cortisol response to ACTH stimulation after dexamethasone suppression; hostility was related to a high level of mean basal cortisol and a high cortisol in cortisol/ACTH ratio, while vital exhaustion was characterized by a low level of mean basal ACTH and a decreased ACTH in relation to cortisol. The adrenocortical patterns, i.e. a high ACTH-low cortisol; a high cortisol; and a low ACTH-low mean basal cortisol, as related to Type A behaviour, hostility and exhaustion, respectively, are in line with the traditional physiological stress model and suggest that different adrenocortical responses might be able to identify different mental stress processes. Sense of control has been suggested to be a key concept for psychological understanding of this finding.     

A Developing Model Of Exploratory Psychotherapeutic Research: The Process Within The Process

A method to facilitate exploratory or discovery-oriented psychotherapy process research is presented. The personal and professional contexts out of which the need for this new approach to psychotherapy process research arose are described. Several changes in scientific values and beliefs that have occurred as a consequence of the development and use of this methodology are noted.     

Cognitive styles and person–environment fit: Investigating the consequences of cognitive (mis)fit

There is currently considerable interest in the key elements of person–environment fit to understand vocational behaviour and to develop strategic human resource management practices. In the light of this interest, we wanted to investigate (1) whether people within similar functions have similar cognitive styles, and (2) what the consequences of cognitive (mis)fit are on three work attitudes, using two large-scale databases (N = 24,267 and N = 2,182). We identified a knowing-oriented cognitive climate in finance, information technology (IT), and research and development (R&D) functions; a planning-oriented cognitive climate in administrative and technical and production functions; and a creating-oriented cognitive climate in sales and marketing functions and general management. Furthermore, we found that the relationship between people's cognitive styles and work attitudes (i.e., job satisfaction, job search behaviour, and intention to leave) does not depend on the cognitive climate in which they work. However, we did find that people with a higher creating style on average score higher on intention to leave and job search behaviour in comparison with people who score lower on the creating style, irrespective of the cognitive climate they are working in. The cognitive climate also partially affects job satisfaction and intention to leave after controlling for cognitive styles. In summary, cognitive styles and cognitive climate seem to have separate influences on people's work attitudes. Our findings are relevant for selection and recruitment policies of organizations and in the context of training, job design, and workforce planning.     

Modeling Intraindividual Cognitive Change in Aging Adults: Results from the Einstein Aging Studies

This paper reviews research from the longitudinal Einstein Aging Studies (EAS) that has focused on modeling intraindividual cognitive change in aging adults. We describe how to separate models of intraindividual change at the within-person level from models of individual differences in change at the between-person level. We illustrate this distinction by analyzing new data from the EAS to test the speed hypothesis at the intraindividual level of analyses. The present findings replicate those of Sliwinski and Buschke (1999) by showing that within-person changes in speed predict within-person changes in cognition, but that speed does not substantially attenuate estimates of within-person cognitive decline. We conclude that correct measurement and explanatory modeling of intraindividual change should be the primary focus of longitudinal aging research, and that the more common practice of modeling individual differences in change should be a secondary focus.     

Different Effects of Dual Task Demands on the Speech of Young and Older Adults

Abstract

Young and older adults provided language samples in response to elicitation questions while concurrently performing 3 different tasks. The language samples were scored on three dimensions: fluency, grammatical complexity, and content. Previous research has shown that older adults use a restricted speech register that is grammatically less complex than young adults’ and has suggested that this restricted speech register is buffered from the costs of dual task demands. This hypothesis was tested by comparing language samples collected during a baseline condition with those produced while the participants were performing the concurrent tasks. The results indicate that young and older adults adopt different strategies when confronted with dual task demands. Young adults shift to a restricted speech register when confronted with dual task demands. Older adults, who were already using a restricted speech register, became less fluent although the grammatical complexity and informational content of their speech was preserved. Hence, some but not all aspects of older adults’ speech are buffered from dual task demands.     

Are we aware of the external factors that influence our food intake?

OBJECTIVES: This research examines the extent to which people accurately report some of the external influences on their food intake. DESIGN: In two studies, specific factors (the presence and behavior of others) were manipulated in order to influence the amount of food that individuals consumed. MAIN OUTCOME MEASURES: The main outcomes of interest were participants' spontaneously generated explanations for their food intake (Study 1; n = 122), and their ratings of the importance of several potential determinants of food intake (Study 2; n = 75). RESULTS: In Study 1, there was high concordance between the amounts eaten by members of a dyad, but very few participants indicated that they were influenced by their partner's behavior; they instead identified hunger and taste as the primary determinants of intake. Study 2 showed that participants' intake was strongly influenced by the behavior of others, but people rated taste and hunger as much more important influences on their intake. CONCLUSIONS: If external environmental factors influence people's food intake without their awareness or acknowledgment, then maintaining a healthy diet can be a challenge, with long-term consequences for health and well-being.     

Luther and the German State

This article is a discussion of the instrumentalization of Martin Luther by German historiography in the nineteenth and twentieth centuries for politically-legitimating, purpose providing ('sinnstiftend') and especially national purposes. In the nineteenth century the Luther jubilee of 1883 was one of the highlights of German nationalism, which had developed rapidly since the unification of 1871. During the First and Second World War Luther again was turned into an active supporter of German nationalism. This study focuses on the last large-scale attempt to instrumentalize Luther for national purposes; ie the Luther interpretation in the German Democratic Republic. With the help of a new Luther reception the GDR tried to improve the basis for her own national identity. She intensified her policy of delimitation from the Federal Republic of Germany with the help of a new and very positive Luther image. These East German attempts, however, backfired and were counter productive in their results. The political appeal to an all-German historical personality like Martin Luther could not legitimate a divided Germany. On the contrary, it brought about the opposite, that is it rather stimulated underlying all-German affinities and cohesive forces. Of course East German historians did not aim at "Wiedervereinigung"– which, naturally was a political issue of the highest degree. But, with the aid of Luther, they unconsciously played an important part in setting the stage for German unification.
