An examination of learning processes during critical incident training: implications for the development of adaptable trainees

Three experiments are reported that examined the process by which trainees learn decision-making skills during a critical incident training program. Formal theories of category learning were used to identify two processes that may be responsible for the acquisition of decision-making skills: rule learning and exemplar learning. Experiments 1 and 2 used the process dissociation procedure (L. L. Jacoby, 1998) to evaluate the contribution of these processes to performance. The results suggest that trainees used a mixture of rule and exemplar learning. Furthermore, these learning processes were influenced by different aspects of training structure and design. The goal of Experiment 3 was to develop training techniques that enable trainees to use a rule adaptively. Trainees were tested on cases that represented exceptions to the rule. Unexpectedly, the results suggest that providing general instruction regarding the kinds of conditions in which a decision rule does not apply caused them to fixate on the specific conditions mentioned and impaired their ability to identify other conditions in which the rule might not apply. The theoretical, methodological, and practical implications of the results are discussed.     

Reinforcement value and substitutability of sucrose and wheel running: implications for activity anorexia

Choice between sucrose and wheel-running reinforcement was assessed in two experiments. In the first experiment, ten male Wistar rats were exposed to concurrent VI 30 s VI 30 s schedules of wheel-running and sucrose reinforcement. Sucrose concentration varied across concentrations of 2.5, 7.5, and 12.5%. As concentration increased, more behavior was allocated to sucrose and more reinforcements were obtained from that alternative. Allocation of behavior to wheel running decreased, but obtained wheel-running reinforcement did not change. Overall, the results suggested that food-deprived rats were sensitive to qualitative changes in food supply (sucrose concentration) while continuing to defend a level of physical activity (wheel running). In the second study, 15 female Long Evans rats were exposed to concurrent variable ratio schedules of sucrose and wheel-running, wheel-running and wheel-running, and sucrose and sucrose reinforcement. For each pair of reinforcers, substitutability was assessed by the effect of income-compensated price changes on consumption of the two reinforcers. Results showed that, as expected, sucrose substituted for sucrose and wheel running substituted for wheel running. Wheel running, however, did not substitute for sucrose; but sucrose partially substituted for wheel running. We address the implications of the interrelationships of sucrose and wheel running for an understanding of activity anorexia.     

The creativity quotient: An objective scoring of ideational fluency

A classical test for accessing the potential creativity of an individual is based on ideational fluency, where a person is asked to generate all possible uses for a familiar item like a piece of paper. In scoring the results, it is intuitive that the suggested uses should not be weighted equally. Those suggested in radically different categories are “worth more”; than those suggested within the same category only. We used information theory to derive a simple mathematical expression for a more objective measure of ideational fluency. We call this the creativity quotient (CQ). This innovative measure was examined using a small sample of participants, and is illustrated by the responses of two typical individuals from an ideational fluency task. The CQ accounts for the number of ideas (fluency), plus the number of categories (flexibility). Ongoing research will examine the independence of CQ from established measures of intelligence and personality.     

Translating Recategorization Strategies Into an Antibias Educational Intervention

This experiment explored whether the benefits of a complete recategorization and a dual identity might effectively be translated into an intervention program designed to reduce prejudice among European Portuguese and African Portuguese 9‐ to 11‐year‐old children. Participants interacted for 45 minutes in weekly sessions for a month. One month after the last interaction, measures were administered to the children. Results revealed that only recategorization reduced prejudice over time relative to the control condition. Consistent with a functional perspective regarding which representation would most effectively promote their group's goals, a one‐group representation was more effective for the African Portuguese minority group.     

Training in Timing Improves Accuracy in Golf

In this experiment, the authors investigated the influence of training in timing on performance accuracy in golf. During pre- and posttesting, 40 participants hit golf balls with 4 different clubs in a golf course simulator. The dependent measure was the distance in feet that the ball ended from the target. Between the pre- and posttest, participants in the experimental condition received 10 hr of timing training with an instrument that was designed to train participants to tap their hands and feet in synchrony with target sounds. The participants in the control condition read literature about how to improve their golf swing. The results indicated that the participants in the experimental condition significantly improved their accuracy relative to the participants in the control condition, who did not show any improvement. We concluded that training in timing leads to improvement in accuracy, and that our results have implications for training in golf as well as other complex motor activities.     

Preattentive Processing,Poststimulus Elaboration,and Memory for Emotionally Arousing Stimuli

A Monte-Carlo simulation was conducted to assess the extent that a correlation estimate can be inflated when an average-based measure is used in a commonly employed correlational design. The results from the simulation reveal that the inflation of the correlation estimate can be substantial, up to 76%. Additionally, data was re-analyzed from two previously published studies to determine the extent that the correlation estimate was inflated due to the use of an averaged based measure. The re-analyses reveal that correlation estimates had been inflated by just over 50% in both studies. Although these findings are disconcerting, we are somewhat comforted by the fact that there is a simple and easy analysis that can be employed to prevent the inflation of the correlation estimate that we have simulated and observed.     

Helping Spouses Cope with Partners Coming Out: A Solution-Focused Approach

This article reviews previous research on coping strategies of spouses with partners who have come out. The current research on coping strategies has come from the work of Amity Pierce Buxton. Next the article examines previous treatment methods used with spouses of gay, lesbian, and bisexual partners. Solution-focused brief therapy (SFBT) is discussed and suggested as an approach with this population. A case example is presented to show how SFBT was used with a client struggling with the news of her partner coming out. Finally, the implications of using SFBT and how the approach helps partners progress through Buxton's stages is discussed.     

A comparison of obese and normal-weight families' sychological characteristics

Abstract

The present study assessed obese and normal-weight family members' perceptions of their nuclear family's social and environmental characteristics. Preliminary results support previous correlational and case studies that suggest obese families are dysfunctional. Results from the Family Environment Scale indicate that obese families perceive their family characteristics differently compared to normal-weight families or to a representative sample of families. Specifically, obese families perceive their homes as less cohesive, more conflictual, less interested in social and cultural activities, and less organized compared to normal-weight families. Obese parents also perceive themselves as more controlling and their families as less independent compared to nonobese parents.     

The effects of action,normality, and decision carefulness on anticipated regret: Evidence for a broad mediating role of decision justifiability

Two distinct theoretical views explain the effects of action/inaction and social normality on anticipated regret. Norm theory (Kahneman & Miller, 1986) emphasises the role of decision mutability, the ease with which one can imagine having made a different choice. Decision justification theory (Connolly & Zeelenberg, 2002) highlights the role of decision justifiability, the perception that the choice was made on a defensible basis, supported by convincing arguments or using a thoughtful, comprehensive decision process. The present paper tests several contrasting predictions from the two theoretical approaches in a series of four studies. Study 1 replicated earlier findings showing greater anticipated regret when the chosen option was abnormal than when it was normal, and perceived justifiability mediated the effect. Study 2 showed that anticipated regret was higher for careless than for careful decisions. Study 3 replicated this finding for a sample holding a different social norm towards the focal decision. Finally, Study 4 found that, when decision carefulness, normality and action/inaction were all specified, only the former showed a significant effect on anticipated regret, and the effect was again mediated by perceived justifiability. Decision justification theory thus appears to provide a better account of anticipated regret intensity in this context than does norm theory.
