Racial bias in the decision to shoot can be minimized if individuals have ample cognitive resources to regulate automatic reactions. However, when individuals are fatigued, cognitive control may be compromised, which can lead to greater racial bias in shoot/don't-shoot decisions. The current studies provide evidence for this hypothesis experimentally using undergraduate participants (Study 1) and in a correlational design testing police recruits (Study 2). These results shed light on the processes underlying the decision to shoot and, given the high prevalence of fatigue among police officers, may have important practical implications.  相似文献

In the current study, the authors investigated the relationship between faith maturity, religious coping, experiential avoidance (EA), and psychological maladjustment (depression, anxiety, and stress) among a sample of Christian college students (N?=?84). Findings revealed a strong positive correlation between faith maturity and positive religious coping, and weak negative correlations between faith maturity and negative religious coping and maladjustment. Moreover, a weak negative correlation emerged between positive religious coping and maladjustment, as well as a moderate positive correlation between negative religious coping and maladjustment. Finally, consistent with the proposed hypothesis, EA partially mediated the link between negative religious coping and psychological maladjustment, although EA played no mediating role with positive religious coping and maladjustment. Further studies are needed to replicate and generalise these preliminary findings.  相似文献

We formulate a new modal ontological argument; specifically, we show that there is a possible world in which an entity that has at least the property of omnipotence exists. Then we argue that if such an entity is possible, it is necessary as well.  相似文献

The present research addresses whether narcissists are more overconfident than others and whether this overconfidence leads to deficits in decision making. In Study 1, narcissism predicted overconfidence. This was attributable to narcissists' greater confidence despite no greater accuracy. In Study 2, participants were offered fair bets on their answers. Narcissists lost significantly more points in this betting task than non‐narcissists, due both to their greater overconfidence and greater willingness to bet. Finally, in Study 3, narcissists' predictions of future performance were based on performance expectations rather than actual performance. This research extends the literature on betting on knowledge to the important personality dimension of narcissism. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

Information about the structure of a causal system can come in the form of observational data—random samples of the system's autonomous behavior—or interventional data—samples conditioned on the particular values of one or more variables that have been experimentally manipulated. Here we study people's ability to infer causal structure from both observation and intervention, and to choose informative interventions on the basis of observational data. In three causal inference tasks, participants were to some degree capable of distinguishing between competing causal hypotheses on the basis of purely observational data. Performance improved substantially when participants were allowed to observe the effects of interventions that they performed on the systems. We develop computational models of how people infer causal structure from data and how they plan intervention experiments, based on the representational framework of causal graphical models and the inferential principles of optimal Bayesian decision‐making and maximizing expected information gain. These analyses suggest that people can make rational causal inferences, subject to psychologically reasonable representational assumptions and computationally reasonable processing constraints.  相似文献

In two studies, subjects judged the desirability of distributions of life expectancy or money. Their judgments showed declining marginal utility. That is, they were less sensitive to changes at the high end of each scale. Subjects also made utility ratings of the outcomes of individuals. And they made ratings of the distributions when these were described in terms of utility ratings rather than goods (years or dollars). The judgments of utility ratings showed equivalent declining marginal utility, even though they were based on utilities that themselves declined marginally. People extend their intuition about declining marginal utility to utility itself, as if utility had utility that declined marginally. In one experiment, a similar result was found with gambles: people are risk averse for utility as well as for money. We argue that this is an overextension of a reasonable heuristic and that this heuristic may account for one classic objection to utilitarian distributions.

ABSTRACT

Scholars have employed three interpretive strategies to explain how Locke understands the metaphysical relationship between a superadded property and the material body to which it is affixed. The first is the mechanist strategy advanced by Michael Ayers and Edwin McCann. It argues that the mechanical affections of a given body are causally responsible for the operation of superadded powers. The second is the extrinsic strategy found in Mathew Stuart. It argues that Locke, who rejects mechanism, does not intend to ground superadded properties in the mechanical affections of material bodies. The third is the essentialist strategy developed by Lisa Downing. It argues that Locke, who does not adhere to mechanism, nevertheless intends to ground superadded properties in the real constitutions of their bearers. However, according to Downing, what grounds superadded properties are the nonmechanical affections of material bodies. My aim in this paper is to expand and strengthen the case for the extrinsic reading. I argue that what is recommended by Locke's writings on this topic is a thoroughly extrinsic interpretation according to which superaddition pertains exclusively to those properties for which no possible arrangement of mechanical or nonmechanical affections is causally sufficient.  相似文献

We examined the moderating effects of age and cognitive reserve on the relationship between body mass index (BMI) and processing speed, executive function, and working memory based on the literature suggesting that obese individuals perform more poorly on measures of these abilities. Fifty-six healthy, dementia-free community-dwelling older (mean age 65.72 ± 7.40) and younger (mean age 21.10 ± 2.33) adults completed a neuropsychological battery and reported height and weight. Mixed effects models were used to evaluate the interactive effects of age, education (a proxy for cognitive reserve), and BMI on cognitive scores. Higher education was protective for executive deficits in younger, but not older adults. Age differences in executive functions were reduced at higher education levels but increased in individuals with higher BMI. Results suggest the inter-relationships between cognitive reserve – as measured by education – and BMI differ across age, and that obesity may accelerate the cognitive aging process.  相似文献

The effectiveness of functional communication training as treatment for problem behavior depends on the extent to which treatment can be extended to typical environments that include unavoidable and unpredictable reinforcement delays. Time‐based progressive delay (TBPD) often results in the loss of acquired communication responses and the resurgence of problem behavior, whereas contingency‐based progressive delay (CBPD) appears to be effective for increasing tolerance for delayed reinforcement. No direct comparison of TBPD and CBPD has, however, been conducted. We used single‐subject designs to compare the relative efficacy of TBPD and CBPD. Four individuals who engaged in problem behavior (e.g., aggression, vocal and motor disruptions, self‐injury) participated. Results were consistent across all participants, and showed lower rates of problem behavior and collateral responses during CBPD than during TBPD. The generality of CBPD treatment effects, including optimal rates of communication and compliance with demands, was demonstrated across a small but heterogeneous group of participants, reinforcement contingencies, and contexts.  相似文献
