Comments on the original article, "Nonrational processes in ethical decision making" by M. D. Rogerson et al (see record 2011-19198-001). Among the many insightful points made by Rogerson, Gottlieb, Handelsman, Knapp, and Younggren (October 2011) regarding nonrational processes in ethical decision making, one deserves further explication: Many of psychologists' ethical decisions lead to actions done to someone. Unfortunately, frameworks and models of ethical decision making frequently neglect this fact by implying that the decisions happen in the abstract, but in truth, these decisions often affect a specific recipient. Importantly, the characteristics of that specific recipient, especially as perceived by the psychologist, can have a powerful impact on the process of ethical decision making (Caughron et al., 2011). It would be wise to add such a hypothetical to the list of specific questions that Rogerson et al recommended psychologists ask themselves: Would I make the same ethical decision if the person(s) toward whom the decision is directed had different characteristics? 相似文献

People must often engage in sequential sampling in order to make predictions about the relative quantities of two options. We investigated how directional motives influence sampling selections and resulting predictions in such cases. We used a paradigm in which participants had limited time to sample items and make predictions about which side of the screen contained more of a critical item. Sampling selections were biased by monetary desirability manipulations, and participants exhibited a desirability bias for both dichotomous and continuous predictions. 相似文献

When students learn scientific theories that conflict with their earlier, naïve theories, what happens to the earlier theories? Are they overwritten or merely suppressed? We investigated this question by devising and implementing a novel speeded-reasoning task. Adults with many years of science education verified two types of statements as quickly as possible: statements whose truth value was the same across both naïve and scientific theories of a particular phenomenon (e.g., “The moon revolves around the Earth”) and statements involving the same conceptual relations but whose truth value differed across those theories (e.g., “The Earth revolves around the sun”). Participants verified the latter significantly more slowly and less accurately than the former across 10 domains of knowledge (astronomy, evolution, fractions, genetics, germs, matter, mechanics, physiology, thermodynamics, and waves), suggesting that naïve theories survive the acquisition of a mutually incompatible scientific theory, coexisting with that theory for many years to follow. 相似文献

Accessory stimuli (AS) are task-irrelevant events (typically an auditory tone) that speed reaction time (RT). With two conditions (AS-present, AS-absent) it is unclear whether AS-presence causes benefits or AS-absence causes costs, possibly due to the expectancy violations. The current study added a third condition where AS were absent in blocks and not expected (pure blocks); in other blocks, AS occurred with a probability of 0.5 (mixed blocks), allowing cost-benefit analysis comparing AS-absent RTs in pure and mixed blocks. Results demonstrated RTs were slower when AS were absent, regardless of whether the absence occurred in a mixed block or a pure block, suggesting AS do provide a benefit to RT. Additionally, AS-facilitation across the RT distribution was analysed using cumulative distribution frequencies and ex-Gaussian parameter estimation. Both provided converging evidence that AS-facilitation increases towards the slower end of the RT distribution. The implications for the utility of AS paradigms are discussed. 相似文献

Published psychological research attempting to support the existence of small and medium effect sizes may not have enough participants to do so accurately, and thus, repeated trials or the use of multiple items may be used in an attempt to obtain significance. Through a series of Monte-Carlo simulations, this article describes the results of multiple trials or items on effect size estimates when the averages and aggregates of a dependent measure are analyzed. The simulations revealed a large increase in observed effect size estimates when the numbers of trials or items in an experiment were increased. Overestimation effects are mitigated by correlations between trials or items, but remain substantial in some cases. Some concepts, such as a P300 wave or a test score, are best defined as a composite of measures. Troubles may arise in more exploratory research where the interrelations among trials or items may not be well described. 相似文献

Evidence attests to the efforts made by minority groups to defend and promote ‘distinctive’ attributes that potentially define the ingroup. However, these attributes are often only available to a prototypical minority within the minority category. In two studies we tested the hypothesis that, under certain conditions, large projected increases in the numerical strength of a ‘distinctive’ attribute (emotional intelligence in Study 1; ingroup language in Study 2) within a minority category can paradoxically evoke less-than-positive reactions from those who already have the attribute. Findings confirmed that while a large projected increase in the numerical strength of a ‘distinctive’ attribute was viewed positively when the comparative context focused on the inter-category relation with a majority outgroup, this increase was viewed less positively, and as undermining their own identity, in a narrower intra-category context. Implications for identity management strategies in minority groups are discussed. 相似文献

Occurrence of the home disadvantage in professional ice hockey was examined by analyzing shootout data from 2005 through 2008. Results indicated that teams involved in shootouts playing at their home arenas did not lose significantly more games at home than on the road. Results did not support the hypotheses that emphasize the roles of physical contact and diffusion of responsibility in accounting for past failures to find the home disadvantage in professional ice hockey. 相似文献

Personality disorders are associated with fundamental disturbances of self and interpersonal relations, problems that vary in severity within and across disorders. This review surveyed clinician-rated measures of personality psychopathology that focus on self-other dimensions to explore the feasibility and utility of constructing a scale of severity of impairment in personality functioning for DSM-5. Robust elements of the instruments were considered in creating a continuum of personality functioning based on aspects of identity, self-direction, empathy, and intimacy. Building on preliminary findings (Morey et al., 2011 /this issue), the proposed Levels of Personality Functioning will be subjected to extensive empirical testing in the DSM-5 field trials and elsewhere. The resulting version of this severity measure is expected to have clinical utility in identifying personality psychopathology, planning treatment, building the therapeutic alliance, and studying treatment course and outcome. 相似文献
