Rates of pathological gambling have increased with the availability of legalized gambling. Substance-abuse units increasingly recognize the need to assess for gambling problems. The South Oaks Gambling Screen (SOGS; H. R. Lesieur & S. B. Blume, 1987) has filled this need. Previous research (M. Oehlert & K. Nelson, 2004) has considered the feasibility of reducing the length of the SOGS while maintaining its ability to identify people at risk for problematic gambling. In this study, the authors examined the utility of a shortened SOGS (SSOGS) in a 2nd sample of veterans with addictions. The authors used data analysis to explore SSOGS psychometric properties and to provide additional support for use of the shorter instrument.  相似文献

The winner's curse phenomenon refers to the fact that the winner in a common value auction, in order to actually win the auction, is likely to have overestimated the item's value and consequently is likely to gain less than expected and may even lose (i.e., it is said to be “cursed”). Past research, using the “Acquiring a company” task has shown that people do not overcome this bias even after they receive extensive feedback. We suggest that the persistence of the winner's curse is due to a combination of two factors: variability in the environment that leads to ambiguous feedback (i.e., choices and outcomes are only partially correlated) and the tendency of decision makers to learn adaptively. We show in an experiment that by reducing the variance in the feedback, performance can be significantly improved. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Experiments on three two‐person threshold public good provision games, namely, the simultaneous, sequential, and dictator games, are conducted to explore the motives behind giving. Players who move simultaneously are endowed with equal bargaining power, and players who move first are endowed with more bargaining power than players who move subsequently. Dictators are indubitably endowed with complete bargaining power. Since the differences between the bargaining powers of two players increase from the simultaneous to the sequential to the dictator game, comparisons among games allow us to trace whether the contribution behavior is motivated by fairness or is simply due to the strategic concern. The experimental evidence shows that the strategic concern explains the overall contribution behavior better than the motive of fairness. However, in the final round 26% of the dictators share the threshold evenly with their opponents, suggesting that some subjects do play fairly. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

This article is an exposition of deep or critical multiculturalism that is grounded in a mutually respectful dialogue. Such multiculturalism names historical oppressions, recognizes the structural causes of injustice and inequality, and is profoundly open to cultural critique, challenge and change. In order to promote such a multicultural practice, the article makes the case for a dialogical politics of deep and mutual respect in which ethno‐religious sensibilities are validated and welcomed in their rich diversity. In doing so, the article draws upon the author's empirical research on the Muslim minority in contemporary Canada. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

Research suggests that, in some cases, mechanical restraints may function as positive reinforcers. In this study, we conducted a functional analysis of severe aggression exhibited by an individual with a history of wearing arm splints. The results of this functional analysis demonstrated that his aggression was maintained by access to the arm splints. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

This study examined students' use of and attitudes toward social networking sites. Significant gender differences were found regarding the type of information posted and whether students were comfortable with employers seeing this information. There were several items that students were likely to post on their sites but were not comfortable with employers seeing. Implications and suggestions for future research are discussed.  相似文献

Differential emotions theory (DET) (The face of emotion. Appleton‐Century‐Crofts: East Norwalk, CT, 1971) posits that the smile functions in part to communicate and/or reflect social affiliation and plays an important role in children's social development. While children's positive emotion expressions have received attention from peer relations researchers in observational studies and within correlational designs, there is almost no experimental evidence for the impact of the smile. Building on existing studies, the present study examined DET predictions within an experimental design. More specifically, we examined the impact smiles have on lower‐income preschool children's nominations for preferred playmates. Both boys and girls tended to nominate unfamiliar playmates who smiled. Additionally, some evidence suggested that preference for smiling playmates seemed more critical to girls' than boys' social functioning. Unlike among boys, teachers rated girls who exhibited a greater preference for smiling playmates as higher in social competence. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

This study investigated associations between mother–infant interactions and children's subsequent understanding of mind and emotion. Mothers' tendency to comment on their infants' internal world and their general sensitivity to their infants' internal states were measured through coded play interactions at 10 months. The latter measurement included ratings on four aspects of maternal behaviour: mindful facilitation, joint attention commenting, pacing, and affect catching. In contrast to mothers' internal state language, these behaviours did not tap mothers' explicit linguistic representation of their infants' mental states. At 54 months, children's understanding of mind and emotion was measured through a range of false‐belief tasks and an emotion‐understanding task. Multivariate analysis revealed direct positive links between mothers' sensitivity to their infants' internal states and children's later understanding of mind.

The negative reciprocity norm (NRN) is the personal moral code specifying retaliation as a proper response to wrongdoing ( Eisenberger, Lynch, Aselage, & Rohdieck, 2004 ). We examined the role of negative reciprocity in interpreting and reacting to the prison abuses at Abu Ghraib. Results showed that people who believed that American soldiers behaved wrongly at Abu Ghraib were more likely to view punishing the soldiers responsible as a highly moral response and were less likely to contribute money to a charitable organization that helps American soldiers. These relationships were only present among those highly endorsing the negative reciprocity norm.  相似文献
