Causation

As cause we often specify an event the occurrence of which first guaranteed that of the effect. This notion is explicated in a framework of branching worlds in Sections I to V. VI and VII point out its close relations to the concept of an agent's bringing about an event. The topic of the last two sections is the distinction between causes and necessary circumstances. For this purpose conditionals are used, interpreted with respect to branching worlds without a similarity relation between them.     

Judging risk behaviour and risk preference: The role of the evaluative connotation of risk terms

Two experiments investigate the impact of the evaluative connotation of risk terms on the judgment of risk behaviour and on risk preference. In the first experiment we focus on (1) the evaluation congruence of the risk terms with a general risk norm and (2) with subjects' individual risk preference, and its effects on the extremity of judgments of risk behaviour. In the second experiment we address (3) the effects of evaluative connotation of risk terms on risk preference. In the first experiment subjects were presented with four decision problems, each with a risky and a cautious decision option, and were required to judge options. Results showed that the judged discrepancy between the risky and cautious option was larger on scales which were evaluatively congruent with the general risk norm for that specific decision problem or with subjects' individual preference. More specificly, in decision problems for which there was considerable consensus about the risk-norm judgments were more extreme on scales which were congruent with the risk norm, in those problems lacking a clear-cut risk-norm judgments were more extreme on scales congruent with subjects' individual risk preference. In the second experiment we studied the reverse relation between the evaluative connotation of risk terms and risk preference. This experiment demonstrates that using evaluatively biased risk terms can affect risk preference. Using terms which imply a positive evaluation of risk-taking and a negative evaluation of risk avoidance led to increased risk preference, and vice versa. Results are discussed in the context of accentuation theory.     

Commercial cognitive/memory systems: A case study

Commercial cognitive/memory systems are products that enhance human cognition and memory. Using one of our own product developments as a case study, we describe three phases of commercial systems development and evaluation. We review published examples of Phase One research, report two quasi-experimental investigations that are representative of successful Phase Two research, and provide some measures used to assess the product's success in the early stages of Phase Three. Finally, we discuss the use of theories and findings from basic research in cognitive psychology to develop products of value to individuals and society.     

Illusory correlation and attitude-based vested interest

The present studies test whether having a ‘vested interest’ in a particular outcome affects perceived covariation. Vested interest was defined as a function of whether Dutch university students were in favour or against the implementation of a threatening policy (receiving lectures in English as opposed to the native Dutch). In both studies subjects were told that this policy would be tried out at either their own or another comparable university, and that the university chosen would be the one with the greatest proportion of support for the plan. In Study 1 subjects (n = 151) were presented with statements expressing pro or contra attitudes and arguments to the policy. These were ostensibly derived from students at both universities but university affiliation was not indicated. In Study 2 (n = 114) similar information was provided but the statements were attributed to students from the two universities, such that there was an equal proportion of opposition/support for the plan at both universities. We hypothesized that illusory correlations would reflect the vested interest of attitude such that students opposing the policy would overestimate the proportion of opponents to supporters at their own university compared to those in favour of the policy. The results of both studies supported our hypothesis and they also revealed attitude to be a more important predictor of illusory correlation than perceived personal consequences for themselves. The prediction that illusory correlations would be weaker in Study 2 than in Study 1, because it provides less scope for bias, was not supported. The implications of these findings are discussed.     

Leader personality and 360‐degree assessments of leader behavior

To investigate the relationship between personality and multi‐source feedback, we assessed 190 health care managers by applying the Understanding Personal Potential personality test, which provides comprehensive measurement of the Big Five dimensions and eight narrower personality traits. Managers' leadership behaviors were assessed by colleagues, supervisors, a random sample of each manager's subordinates as well as the managers themselves using a 360‐degree change, production, employee (CPE) instrument. Hierarchical multivariate regression analysis showed that the Big Five variables were significantly related to the Managers' leadership behavior in all CPE dimensions. Also, addition of narrow personality variables to the Big Five increased explained variance in leadership behavior. This study is the first of its kind to include the full range of viewpoints in a 360‐degree instrument, along with a large number of subordinate assessments. We found that both the strength of the relationship between personality and behavior and the configuration of different predictors varied depending on who did the rating and what leadership orientation was investigated, and this observation merits further investigation.     

Development and validation of a Christian-based Grief Recovery Scale

The purpose of this study was to develop and validate a Christian-based Grief Recovery Scale (CGRS) which was used to measure Christians recovering from grief after a significant loss. Taiwanese Christian participants were recruited from churches and a comprehensive university in northern Taiwan. They were affected by both the Christian faith and Chinese cultural beliefs. The CGRS is developed through replicated factor analyses in three stages. The final version of the CGRS retains 35 Likert-type items and consists of six factors: spiritual well-being; recovering meaning and sense of control; ongoing physical and emotional responses; reassuring faith; strongly missing a deceased loved one; and life disturbance. The evidence for CGRS reliability and validity is highlighted. Implications for research and counselling practice are suggested.
