Risky Situations (risky + situation)
Selected AbstractsDecision-making in Parkinson's disease patients with and without pathological gamblingEUROPEAN JOURNAL OF NEUROLOGY, Issue 1 2010M. Rossi Background and purpose:, Pathological gambling (PG) in Parkinson's disease (PD) is a frequent impulse control disorder associated mainly with dopamine replacement therapy. As impairments in decision-making were described independently in PG and PD, the objective of this study was to assess decision-making processes in PD patients with and without PG. Methods:, Seven PD patients with PG and 13 age, sex, education and disease severity matched PD patients without gambling behavior were enrolled in the study. All patients were assessed with a comprehensive neuropsychiatric and cognitive evaluation, including tasks used to assess decision-making abilities under ambiguous or risky situations, like the Iowa Gambling Task (IGT), the Game of Dice Task and the Investment Task. Results:, Compared to PD patients without gambling behavior, those with PG obtained poorer scores in the IGT and in a rating scale of social behavior, but not in other decision-making and cognitive tasks. Conclusions:, Low performance in decision-making under ambiguity and abnormal social behavior distinguished PD patients with PG from those without this disorder. Dopamine replacement therapy may induce dysfunction of the ventromedial prefrontal cortex and amygdala-ventral striatum system, thus increasing the risk for developing PG. [source] Trait anger and anger expression style in children's risky decisionsAGGRESSIVE BEHAVIOR, Issue 1 2009Elisa Gambetti Abstract In this study, 104 children completed a task, measuring risk decision-making, and the State-Trait Anger Expression Inventory for Children and Adolescents . Subjects were also asked to evaluate the degree of danger, benefit, fun and fear perceived for each risky choice. Analyses indicated that (a) risk decision-making was predicted by both trait anger and outward expression of anger; (b) appraisal of danger fully mediated the relationship between trait anger and risk; (c) perceptions of benefit, scare and fun partially mediated the relationship between trait anger and risk; and (d) appraisal of danger partially mediated the relationship between outward expression of anger and risk decision-making. The results provide evidence for a relationship between dispositional anger and risk decision-making during childhood, suggesting a possible explanation of the mechanisms below. In particular, risk decision-making can be viewed as the output of cognitive and emotive processes, linked to dispositional anger that leads children to be amused, optimistic and fearless in potentially risky situations. These findings substantiate the importance of incorporating cognitive and emotive factors in theories that seek to explain the relationship between personality traits and risk decision-making across a broad age range.

[source] Naltrexone and Cue Exposure With Coping and Communication Skills Training for Alcoholics: Treatment Process and 1-Year OutcomesALCOHOLISM, Issue 11 2001Peter M. Monti Background: Promising treatments for alcoholics include naltrexone (NTX), cue exposure combined with urge-specific coping skills training (CET), and communication skills training (CST). This study investigated the effects of combining these elements as treatment adjuncts. Methods: A 2 × 2 design investigated the effects of CET combined with CST, as compared with an education and relaxation control treatment, during a 2-week partial hospital program (n= 165) followed by 12 weeks of NTX (50 mg/day) or placebo during aftercare (n= 128). Drinking outcomes were assessed at 3, 6, and 12 months after discharge from the partial hospital. Process measures included urge, self-efficacy (confidence about staying abstinent in risky situations), and self-reported coping skills. Medically eligible alcohol-dependent patients were recruited. Results: Among those compliant with medication on at least 70% of days, those who received NTX had significantly fewer heavy drinking days and fewer drinks on days that they drank than those receiving placebo during the medication phase but not during the subsequent 9 months. CET/CST-condition patients were significantly less likely to report a relapse day and reported fewer heavy drinking days at the 6- and 12-month follow-ups than patients in the control treatment. Interactions of medication with behavioral treatments were not significant. Process measures showed that NTX resulted in lower weekly urge ratings, and those in CET/CST used more of the prescribed coping skills after treatment, reported fewer cue-elicited urges, and reported more self-efficacy in a posttest role-play test. Drinking reductions at 3, 6, and 12 months correlated with more use of coping skills, lower urge, and higher self-efficacy. Conclusions: The results suggest the probable value of keeping alcoholics on NTX for longer periods of time and the importance of increasing compliance with NTX. They also support the earlier promising effects of CET and CST as adjuncts to treatment programs for alcoholics by maintaining treatment gains over at least a year. The value of the urge-specific and general coping skills and of self-efficacy and urge constructs was demonstrated in their association with drinking outcomes. [source] Entrepreneurship and Risk TakingAPPLIED PSYCHOLOGY, Issue 3 2009Anna Macko According to the definition of entrepreneurship and everyday observation, entrepreneurs are perceived as more risk prone than other people. However, laboratory studies do not provide conclusive support for this claim. In our study, three groups of students served as subjects. One group of students did not express any intention of starting up their own business in the near future. The second group consisted of students who had participated in a special course designed for future entrepreneurs. The third group consisted of students or alumni who became entrepreneurs before graduating. In accordance with Knight's claim, we found that actual entrepreneurs revealed the highest, and students who did not express an intention of starting their own business the lowest, level of self-confidence of all groups participating in the experiment. On the other hand, in well-defined risky situations we did not confirm a hypothesis that would-be entrepreneurs or actual entrepreneurs were more risk prone than students with no intention of starting a business. Yet, in naturalistic-business risky situations we found more risky choices among entrepreneurs than among non-entrepreneurs. Conformément à la définition même de l'esprit d'entreprise et à l'observation quotidienne, les entrepreneurs sont perçus comme étant plus enclins que les autres personnes à prendre des risques. Seulement, les recherches expérimentales ne confirment pas de façon définitive cette conception. Notre étude a porté sur trois groupes d'étudiants. L'un des groupes n'avait aucunement l'intention de créer une entreprise dans un avenir prévisible. Le deuxième groupe était composé d'étudiants qui suivaient un cours spécialement destiné aux futurs entrepreneurs. Le troisième groupe rassemblait des étudiants ou d'anciens étudiants qui devinrent entrepreneurs avant d'être diplômés. En accord avec les propositions de Knight, on a constaté que les entrepreneurs étaient ceux qui avaient la plus forte confiance en eux-mêmes et les jeunes qui n'éprouvaient aucune vocation d'entrepreneur la plus faible. D'autre part, face à des situations de risque bien précises, il fut impossible de corroborer l'hypothèse que les aspirants entrepreneurs ou les chefs d'entreprise étaient plus portés sur le risque que les étudiants n'ayant aucunement l'intention de fonder une entreprise. Toutefois, devant des décisions risquées dans des situations concrètes industrielles ou commerciales, on a observé plus de choix aventureux chez les entrepreneurs que chez ceux qui ne l'étaient pas.
