Neuroeconomics: cross-currents in research on decision-making 总被引:1,自引:0,他引:1
Despite substantial advances, the question of how we make decisions and judgments continues to pose important challenges for scientific research. Historically, different disciplines have approached this problem using different techniques and assumptions, with few unifying efforts made. However, the field of neuroeconomics has recently emerged as an inter-disciplinary effort to bridge this gap. Research in neuroscience and psychology has begun to investigate neural bases of decision predictability and value, central parameters in the economic theory of expected utility. Economics, in turn, is being increasingly influenced by a multiple-systems approach to decision-making, a perspective strongly rooted in psychology and neuroscience. The integration of these disparate theoretical approaches and methodologies offers exciting potential for the construction of more accurate models of decision-making. 相似文献

Little is known about long-term prognostic implications of personality disorder (PD) for quality of life (QOL) in the young adult population not selected for psychiatric treatment. The purpose of this study was to determine the association of PDs with QOL assessed after an 11-year interval. PDs were assessed in 1991-1994 at mean age 22, and indicators of QOL were assessed in 2001-2004 at mean age 33 based on a community sample of 588 young adults. Findings indicated that any PD, or a cluster A, B, or C PD each were independently associated with elevated impairment in overall QOL after adjusting for demographic variables, co-occurring Axis I disorder, and physical illness, and PDs in other clusters. Cluster B PD had a greatest adverse impact on QOL. Symptoms of antisocial, borderline, and schizotypal PD symptoms were independently associated with significant reductions in QOL; avoidant, paranoid, and dependent PD symptoms were associated with smaller reductions, not reaching statistical significance. Symptoms of other individual PDs were not associated with reduced QOL. PDs in young adults in the community have an enduring and adverse impact on subsequent QOL that cannot be attributed to physical illness or Axis I psychiatric disorder. 相似文献

Monitoring of ongoing processing plays a critical role in regulating cognitive function. Two event-related potential components, the error-related negativity (ERN) and N2, have been proposed to reflect this monitoring function. Specifically, it has been suggested that both components reflect the role of anterior cingulate cortex (ACC) in monitoring for the occurrence of response conflict. This view appears to be challenged by findings that alcohol consumption and lesions in ACC have dissociable effects on the ERN and N2. Using a computational model, the present research demonstrates that the conflict-monitoring theory can account for these dissociations in terms of the dissociable effects of alcohol and ACC lesions on processing of relevant stimulus information (which determines ERN amplitude) and processing of irrelevant, distracting information (which determines N2 amplitude). The simulation results suggest new interpretations of the cognitive deficits caused by alcohol consumption (impaired stimulus processing) and ACC lesions (impaired attentional control). 相似文献

In a community sample (N = 543) followed over 20 years, the authors studied associations among childhood family violence exposure, personality disorder (PD) symptoms, and adult partner violence. PD symptoms (DSM-III-R Clusters A, B, and C) in early adulthood partially mediated the effect of earlier childhood risks on the odds of perpetrating partner violence. The authors tested whether stability of PD symptoms from adolescence to the early 20s differs for individuals who later perpetrated partner violence. Cluster A ("Odd/Eccentric") symptoms declined less with age among partner violent versus nonviolent men and women. Cluster B ("Dramatic/Erratic") symptoms were more stable through late adolescence in partner violent men, compared with nonviolent men and violent women. Cluster C ("Anxious") symptoms were most stable among partner violent men. 相似文献

Religion and unforgivable offenses 总被引:1,自引:0,他引:1
ABSTRACT The value of forgiveness is emphasized in many religions, but little is known about how members of distinct religious cultures differ in their views of forgiveness. We hypothesized and found that Jews would agree more than Protestants that certain offenses are unforgivable and that religious commitment would be more negatively correlated with belief in unforgivable offenses among Protestants than among Jews (Studies 1 and 2). Dispositional forgiveness tendencies did not explain these effects (Studies 1 and 2). In Study 3, Jews were more inclined than Protestants to endorse theologically derived reasons for unforgivable offenses (i.e., some offenses are too severe to forgive, only victims have the right to forgive, and forgiveness requires repentance by the perpetrator). Differential endorsement of these reasons for nonforgiveness fully mediated Jew-Protestant differences in forgiveness of a plagiarism offense and a Holocaust offense. 相似文献

An immersive virtual reality (IVR) system was used to investigate allocentric spatial memory in a patient (PR) who had selective hippocampal damage, and also in patients who had undergone unilateral temporal lobectomies (17 right TL and 19 left TL), their performance compared against normal control groups. A human analogue of the Olton [Olton (1979). Hippocampus, space, and memory. Behavioural Brain Science, 2, 315] spatial maze was developed, consisting of a virtual room, a central virtual circular table and an array of radially arranged up-turned 'shells.' The participant had to search these shells in turn in order to find a blue 'cube' that would then 'move' to another location and so on, until all the shells had been target locations. Within-search errors could be made when the participants returned to a previously visited location during a search, and between-search errors when they revisited previously successful, but now incorrect locations. PR made significantly more between-search errors than his control group, but showed no increase in within-search errors. The right TL group showed a similar pattern of impairment, but the left TL group showed no impairment. This finding implicates the right hippocampal formation in spatial memory functioning in a scenario in which the visual environment was controlled so as to eliminate extraneous visual cues. 相似文献

The authors examined the incremental validity of the reaction time (RT) measure beyond that of skin conductance response (SCR) in the detection of concealed information. Participants performed a Stroop-like task in which they named the color of critical and neutral words. Results show that the SCR highly differentiated between the relevant and neutral words. However, the RT demonstrated a significant differentiation only when the critical words denoted personally significant items (e.g., one's own name) and not when they denoted crime-relevant items related to a simulated crime. In both cases, combining the 2 measures yielded no advantage over the use of SCR alone. Thus, although behavioral measures may differentiate between relevant and neutral information in some cases, their practical use is questionable. 相似文献

In this microhistory from 1553, set in Montecosaro, in east-central Italy, local officials, armed with their lords permission, set out to catch a Jewish banker in sexual traffic with a Christian. To bait their trap, they hire a local woman, who agrees to be found at night in the bankers house. Two years later, the entrappers, arrested, jailed, and tried for high-handed tactics, recount their version of the enterprise, and the lord, also jailed, gives his. The unfortunate banker, meanwhile, has died of prisons rigors, while the lord has pocketed his fat ransom. Though harsh, the state courts aim to punish all those guilty of justices miscarriage, including the rough handling of a Jewish victim. The article explores the attitudes of small-town Christians to the Jewish banker and strives to re-assemble the dialogue across the religious gap as the trap snaps shut. It also offers a well furbished narrative from a period for which few extended Jewish tales survive. 相似文献
