Competition and sensemaking in ethical situations

Competition was examined in relation to ethicality. The effect of a competitor being an in‐group vs. out‐group member, the competitor offering uncorroborated or corroborated information, and the impact of the competitor goals were examined. The findings suggest that the way competition is presented has an important influence on how individuals make sense of an ethically ambiguous situation and make ethical decisions. A main effect was found, such that when a competitor offered uncorroborated information, participants made less ethical decisions and used pro‐ethical reasoning strategies less often. An additional main effect was found suggesting that participants made more ethical decisions when working with an in‐group competitor rather than an out‐group competitor. Complex interactive effects were also found and discussed.     

Transfer effects in isomorphic problem situations

The results of a recent experiment to assess the relationship between human problem solving behaviour and the structural properties of certain problems are presented. The results suggest that human performance in a problem-solving task is significantly influenced by immediately prior experience on a different but structurally identical problem. Specifically, transfer effects are demonstrated across two problems of isomorphic structure.     

Confidentiality in end-of-life and after-death situations

Confidentiality is one of the foundations on which psychotherapy is built. Limitations on confidentiality in the therapeutic process have been explained and explored by many authors and organizations. However, controversy and confusion continue to exist with regard to the limitations on confidentiality in situations where clients are considering their options at the end of life and after a client has died. This article review these 2 areas and provides some suggestions for future research.     

Centering Predictor Variables in Three-Level Contextual Models

Hierarchical data are becoming increasingly complex, often involving more than two levels. Centering decisions in multilevel models are closely tied to substantive hypotheses and require researchers to be clear and cautious about their choices. This study investigated the implications of group mean centering (i.e., centering within context; CWC) and grand mean centering (CGM) of predictor variables in three-level contextual models. The goals were to (a) determine equivalencies in the means and variances across the centering options and (b) use the algebraic relationships between the centering choices to clarify the interpretation of the estimated parameters. We provide recommendations to assist the researcher in making centering decisions for analysis of three-level contextual models     

Parallel response selection in dual-task situations

Semantic priming and response priming were studied in a dual-task procedure. In two experiments, reaction times to the first and second stimuli were faster when the finger required for the Task 1 response was the same as the finger required for the Task 2 response. Such priming suggests that Task 2 response information was generated prior to the completion of Task 1 response selection. These data pose a potential challenge to the response-selection bottleneck (RSB) theory of dual-task performance, since they may indicate a violation of the discrete-stage processing assumption on which the underlying locus-of-slack logic depends. Accommodating these data while preserving the essential bottleneck character of RSB theory may be possible but may also alter the very nature of the bottleneck itself.

Self-focusing situations and depression

The author examined the situations in which people turn their attention to the self and investigated differences between depressed and nondepressed persons in self-focusing situations. He developed a Self-Focusing Situation List containing 58 items and administered the list to 436 Japanese undergraduates. He also administered a depression scale to part of the sample (n = 365). A factor analysis extracted 6 factors, and cluster analyses of these 6 factors scores yielded 5 clusters. The participants who preferred self-focusing when alone and avoided self-focusing after positive events (Cluster 5) scored higher on the depression scale than did the participants in Clusters 1, 2, 3, and 4.     

Catecholamine excretion in pleasant and unpleasant situations

Catecholamine excretion was studied in 36 students under four different conditions, which involved either playing a game of chance, performing psychological tests, watching surgical films or spending the session in inactivity. Adrenaline excretion was shown to be highest during the game session, which was described by the subjects in the most positive terms. It was concluded that a rise in behavioural arousal level is accompanied by increased adrenaline secretion, also when the arousal increase is induced by a situation regarded as pleasant.     

Guilt and focusing in decision-making

In this paper we examined the impact of a specific emotion, guilt, on focusing in decision-making. Through the focusing mechanism, when making decisions, individuals tend to restrict their thoughts to what is explicitly represented in the decisional task, disregarding alternatives. In this paper, three experiments are performed to investigate whether an emotional state of guilt can critically guide individuals' focusing, and even prevailing over the focusing mechanism. Guilty emotional state was induced by asking participants to write about a guilty related life event. The emotional state was thus neither generated by nor related to the tasks used in the experiments. Results of the first two studies show that guilt affects focusing in decision-making in the case of only one explicitly specified option (a positive or a negative one). Guilty participants, when presented with a stated option that has predominantly positive characteristics, prefer other, unspecified options over the positive one. Guilty participants faced with a stated option that has predominantly negative features tend to prefer it to other, unspecified, options, instead. Finally, experiment 3 shows that guilty participants presented with two different options (a negative vs. a positive one) having different degrees of explicitness (i.e. they are not equally represented in the decision frame), focus on the negative option, even though the latter was not explicitly represented but only hinted at the end of the text. Overall, these results suggest that guilt emotion state can play a crucial role in either strengthening or reducing the focusing mechanism. Copyright © 2006 John Wiley & Sons, Ltd.     

Complex decision-making in early childhood

Decision-making over time is an important aspect of adaptive social functioning. The main goal of this study was to investigate the development of this ability in young children. A simplified version of the Iowa Gambling Task was given to 69 children at 3 ages (3, 4, and 6 years). Children were also given an awareness test to assess their knowledge of the task. Significant age differences were found for awareness of the task while significant sex effects were found for performance on the task. Females chose significantly more from the advantageous decks than would be expected by chance in the second block. Males demonstrated no significant difference in choice of decks. Further analysis indicated female superiority in the task was not due to greater knowledge of the game. One interpretation of these results is that there are two systems affecting decision-making over time.
