Decision-making competence in everyday life: The roles of general cognitive styles,decision-making styles and personality

Research indicates that decision-making competence in everyday life is associated with certain decision-making styles. The aims of this article are to extend this research by examining (a) the extent to which general cognitive styles explain variance in decision-making competence over and above decision-making styles, and (b) the extent to which personality explains variance in decision-making competence over and above both types of style variable. Participants (N = 355) completed measures of everyday decision-making competence (Decision Outcomes Inventory), decision styles (Decision Style Questionnaire; Maximization Inventory), cognitive styles (the Cognitive Styles Inventory; Rational-Experience Inventory), and the Big Five personality variables (IPIP Big-Five factor scales). The results indicate that cognitive styles offer no incremental validity over decision-making styles in predicting decision-making competence, but that personality does offer substantial incremental validity over general cognitive styles and decision-making styles. Jointly decision-making styles and personality account for a substantial amount of variance in everyday decision-making competence.     

Word and letter string processing networks in schizophrenia: evidence for anomalies and compensation

Imaging studies show that in normal language correlated activity between anterior and posterior brain regions increases as the linguistic and semantic content (i.e., from false fonts, letter strings, pseudo words, to words) of stimuli increase. In schizophrenia however, disrupted functional connectivity between frontal and posterior brain regions has been frequently reported and these disruptions may change the nature of language organization. We characterized basic linguistic operations in word and letter string processing in a region-of-interest network using structural equation modeling (SEM). Healthy volunteers and volunteers with schizophrenia performed an fMRI one-back matching task with real words and consonant letter strings. We hypothesized that left hemisphere network dysfunction in schizophrenia would be present during processes dealing with linguistic/semantic content. The modeling results suggest aberrant left hemisphere function in schizophrenia, even in tasks requiring minimal access to language. Alternative mechanisms included increases in right hemisphere involvement and increased top-down influence from frontal to posterior regions.     

Cognitive Reflection Predicts Real‐Life Decision Outcomes,but Not Over and Above Personality and Decision‐Making Styles

The Cognitive Reflection Test (CRT), designed to assess the ability to inhibit intuition to process a problem analytically, predicts people's performance in many normative judgement and decision‐making tasks (e.g., Bayesian reasoning, conjunction fallacy and ratio bias). However, how the CRT predicts normative decision‐making performance is unclear, and little is known about the extent to which the CRT predicts real‐life decision outcomes. We investigate the role of the CRT in predicting real‐life decision outcomes and examine whether the CRT predicts real‐life decision outcomes after controlling for two related individual differences: the Big Five personality traits and decision‐making styles. Our results show that greater CRT scores predict positive real‐life decision outcomes measured by the Decision Outcome Inventory. However, the effect size was small, and the relationship became non‐significant after statistically controlling for personality and decision‐making styles. We discuss the limited predictive role of cognitive reflection in real‐life decision‐making outcomes, along with the roles of personality and decision‐making styles.

The latent structure of decision styles

Responding to calls for theoretical development in research on decision styles, this article focuses on their structural relationships. A two-component model of decision styles is proposed. One component, pertaining to dual process theories of thinking, is concerned with the processes people use to make decisions, and the other is concerned with processes used to regulate decisions (e.g. whether they should be made immediately or delayed). The results of a first study (N = 629) using items from a comprehensive decision style measure (the Decision Styles Questionnaire), support the two-component model. The results of a second study (N = 305), based on an alternative set of style measures, provide support for an extended version of the model. Implications of the theory and research findings for future work on decision styles are discussed.
