Effects of a Communication Skills Training Programme on the Cognitions of Careers Guidance Students

Traditionally, communication skills training has focused principally on overt behaviours that are clearly identifiable. In recent years there has been an increasing awareness that cognitive processes can have considerable influence on behaviour. An attempt was made to establish whether changes in cognitions occurred as a result of a behaviourally-based communication skills training programme in which there had been no explicit attempt to bring about such cognitive changes. More specifically, the study examined whether such a programme resulted in changes in aspects of the personal construct space of students on a Diploma in Careers Guidance course. The results offered some support for the hypothesis that the programme produced changes in the students' personal construct space.     

The application of relative deprivation theory to justice perception of preferential selection

This study attempted to apply the relative deprivation theory to preferential selection research. Two questions were addressed in this context: First, does preferential selection cause feelings of injustice or deprivation? and, second, can the magnitude of such feelings of injustice be predicted? A questionnaire was designed to assess fairness perceptions of all types of selection outcomes: preferential selection; together with selection involving discrimination against minorities and selections without either forms of discrimination. Results showed that preferential selection caused feelings of injustice. The level of felt injustice associated with preferential selection was identical to that due to discrimination against minorities. Further, the magnitude of felt injustice due to preferential selection could be predicted by the size of the discrepancy in “performance-relevant merits” between the selected minority candidate and the unsuccessful majority candidate. The study also compared effects of the “self-other” comparison process, used in previous relative deprivation research, and a “other-other” comparison process on justice perception. Implications of the results for the application of relative deprivation theory to preferential selection research were discussed.     

The influence of affect on self-focused attention: Conceptual and methodological issues

A number of investigators have suggested that affective states influence the focus of attention. One recent proposal is that negative moods increase self-focus. This review considers the evidence that bears on this hypothesis. Conceptual issues pertaining to the construct of self-focus are discussed first. Next, the various parameters that influence attentional focus are presented in order to provide a way of organizing the mood/selffocus literature. Studies that have used state measures of mood and self-focus are considered in this context. Methodological limitations of existing studies are discussed and directions for future work provided.     

Motion coherence and conjunction search: Implications for guided search theory

Feature integration theory has recently been revised with two proposals that visual conjunction search can be parallel under some circumstances—either because items with nontarget features are inhibited, or because items with target features are excited. We examined whether excitatory or inhibitory guidance controlled conjunction search for an X oscillating in one direction among Os oscillating in that direction and Xs oscillating in another. Search was affected by whether items oscillated in phase with each other, and it was exceptionally difficult when items with target motion moved out of phase with each otherand items with nontarget motion moved out of phase. The results suggest that conjunction search can be guided both by excitation of target features and by inhibition of nontarget features.     

The architecture of complexity: A new blueprint

The logic of scientific discovery is now a concern of computer scientists, as well as philosophers. In the computational approach to inductive inference, theories are treated as algorithms (computer programs), and the goal is to find the simplest algorithm that can generate the given data. Both computer scientists and philosophers want a measure of simplicity, such that simple theories are more likely to be true than complex theories. I attempt to provide such a measure here. I define a measure of simplicity for directed graphs, inspired by Herbert Simon's work. Many structures, including algorithms, can be naturally modelled by directed graphs. Furthermore, I adapt an argument of Simon's to show that simple directed graphs are more stable and more resistant to damage than complex directed graphs. Thus we have a reason for pursuing simplicity, other than purely economical reasons.This paper is based on part of my doctoral dissertation.

工作负载的测量和评定

长期处于应激状态而又适应不良者可导致疾病。人类经常遇到的心理、社会性应激源除了生活事件以外,长期工作负载过重也是其中之一。本文通过对24名在监护病房工作的护士的工作负载的测量介绍了在西方国家常用的工作负载的测量和评定方法。     

Cognitive guidelines for simplifying medical information: Data framing and perception

In this paper, 1 describe psychological guidelines for simplifying medical information — methods to aid the perception and recognition of abnormalities in medical test reports. These techniques resemble natural human editing strategies outlined in prospect theory. The methods pre-edit data as humans do but to reduce human effort. I review empirical studies assessing these techniques and discuss needs for further research.
