Individual differences in fast-and-frugal decision making: Neuroticism and the recognition heuristic

The fast-and-frugal recognition heuristic (RH) claims that people base inferences on recognition only, thus ignoring further knowledge they possess. This claim has been repeatedly challenged, while recent evidence suggests that there are substantial individual differences in adhering to the RH. However, no personality or ability factors driving (non-)use of the RH have, as yet, been identified. In the present study, neuroticism was hypothesized to be a determinant of using the RH: participants high in neuroticism were expected to avoid making use of their knowledge beyond recognition, thus avoiding a diagnostic test of their abilities. The results corroborate this hypothesis: neuroticism predicted participants’ adherence to the RH while the other Big 5 factors and intelligence yielded no additional explanatory power. Moreover, the effect of neuroticism was not mediated by the accessibility of knowledge thus lending preliminary support for the notion that this effect may, in fact, be genuinely motivational in nature.     

Dimension integration: Testing models without trade-offs

This paper tests a behavioral property called dimension integration. The test evaluates models, such as lexicographic semi-orders and the priority heuristic, which assume that a person uses only one dimension at a time. It provides a way to compare such models against those that assume a person combines information from different dimensions. The test allows one to test the hypothesis that different people use different lexicographic semi-orders with different threshold parameters. In addition, by use of a “true and error” model, it is possible to “correct” for unreliability of choice in order to estimate the proportions of participants who show different response patterns that can be classified as integrative or not integrative. An experiment with 260 participants was conducted in which people made choices between two-branch gambles. The aggregate results violate the priority heuristic and six lexicographic semi-orders. The data also refute the theory that people use a mixture of these lexicographic semi-orders. In addition, few individuals appear to show response patterns consistent with non-integrative models. Instead, they show that most individuals show patterns consistent with the hypothesis that they combine information between dimensions.     

Learning from experience: Examining the impact of client work upon two trainee therapists

This qualitative research study, focusing on the learning and change of two trainee therapists over a nine‐month period, was conducted by the trainees themselves. In collecting and analysing their data, the researchers made use of the heuristic methodology, to which some of the principles of the co‐operative inquiry methodology were added. The findings shed light on some of the ways in which trainee counsellors and psychotherapists might learn through their work with clients, the forms and contexts in which this learning may arise, and how the learning might affect the trainees. The findings additionally highlight some of the possible benefits of engaging in research for trainee counsellors and psychotherapists, in terms of their roles as practitioners. These include positive changes in the ways in which they work with clients, and changes in the ways they think about their practice.     

Who will win Wimbledon? The recognition heuristic in predicting sports events

Goldstein and Gigerenzer ( 2002 ) described the recognition heuristic as a fast, frugal, and effective decision strategy. However, most studies concerning the recognition heuristic have been conducted in static domains, that is, in domains where it could plausibly be argued that relevant variables stay relatively constant. Yet the question is whether the heuristic would also work in dynamic environments where the quality of the actors rises and falls, such as in sports. We tested performance of the recognition heuristic in a dynamic environment and used it to predict the outcomes of tennis matches in Wimbledon 2003. Recognition data of amateur tennis players and laypeople was used to build recognition rankings. These rankings correlated with official rankings and led to at least as good predictions. Simulations of individual choices showed high recognition validities of both amateurs (0.73) and laypeople (0.67). In a second study the recognition heuristic correctly predicted 90% of actual individual choices. Overall, the recognition heuristic may be effectively generalized to dynamic environments.

Researching psychotherapy integration: A heuristic approach

Moustakas argues that questions and methodology in heuristic research flow out of inner awareness, meaning and inspiration. The approach might arguably embrace a combination of qualitative research methods, and constitute a kind of bricolage. This paper describes a heuristic enquiry into psychotherapy integration that used such a combination of methods – an interpretative phenomenological approach, case studies, reflexive action, and writing. It demonstrates how each of these methods contributed to the six phases of heuristic enquiry, from the initial engagement with psychotherapy as a trainee to the creative synthesis of published works and a PhD thesis, together with some reflection on the enquiry's limitations and rigour. Published texts, training, clinical practice and reflexivity constituted the material from which a new organizing framework for understanding psychotherapy integration was formulated. The author reflects on how the research design allowed deep engagement with this material, and changed his perspective of psychotherapy integration. In conclusion, this paper suggests that both psychotherapy integration and heuristic enquiry can only be conducted on an individual and personal basis, and that it is the quality of the relationship, with the client, or the research material, that produces results.     

Familiarity can increase stereotyping

Two experiments show that repeated exposure to information about a target person reduces individuation and thereby increases stereotyping of the target person based on social group memberships. The effect is not due to familiarity-induced liking (the mere exposure effect), nor is it mediated by increased accessibility of the target’s social category, nor by increases in perceived social judgeability. The results are most consistent with the use of feelings of familiarity as a regulator of processing mode, such that familiar objects receive less systematic or analytic processing. In everyday life, frequent exposure to another person ordinarily produces not only familiarity but also liking, individuated knowledge, and friendship, factors that may effectively limit stereotyping. But when previous exposure is unconfounded from these other factors, its effect can be to increase stereotyping.     

How strong is the comparison‐to‐the‐strongest heuristic?: An empirical test of the comparison‐ to‐the‐strongest heuristic in probability judgment1,2

Abstract: Windschitl and Wells (1998 ) proposed that the pairwise comparison between the focal and strongest alternative outcomes plays an important role in probability judgment. However, their studies did not control the effects of alternative outcomes other than the strongest one. This article tested whether only the strongest alternative outcome would affect probability judgment, using a variable selection method in a multiple regression analysis. Study 1 reanalyzed the results of Windschitl and Young (2001 ) and showed that only the strongest alternative outcome affects probability judgment. In Study 2, a new experiment was conducted to modify the methodological problems in Study 1. The results of Study 2 were identical to those of Study 1. All these results consistently supported the comparison hypothesis.     

Individual differences in trait urgency moderate the role of the affect heuristic in adolescent binge drinking

This study investigated the roles of the affect heuristic and outcome beliefs in explaining the relationship between negative urgency and adolescent binge drinking behaviour. The sample consisted of 391 Australian high school students, who were selected to be low or high on urgency. We hypothesised that highly urgent adolescents would be more likely than adolescents low in urgency to utilise the affect heuristic (i.e., to rely upon affective input) when making alcohol-related decisions. Multiple-group path analysis supported this prediction. Adolescents high in urgency exhibited greater use of the affect heuristic by displaying a direct path from affective associations to binge drinking; whereas adolescents low in urgency exhibited greater reliance upon rational processing by displaying an indirect path via outcome beliefs.     

The automated cockpit: A comparison of attitudes towards human and automated pilots

Automation is being used extensively in aviation, particularly in the aircrafts themselves. The airline industry benefits from automation because it often increases efficiency and performance. To date, automation research has focused largely on operator trust and reliance, while largely ignoring the role of affect and trust in shaping the attitudes of the novice consumer. In two studies, we found that participants rated a human pilot more favorably than an auto-pilot. However, attitudes toward the automated pilot were more favorable in a high priced compared to a low priced ticket condition, indicating that participants used price to infer quality. In Study 2, inducing positive affect increased ratings of an automated pilot. Path analyses provided additional evidence that perceptions of automation are largely influenced by feelings.
