Previous research has found that people are often averse to inequity, even when it works to their own advantage. The present research extends previous demonstrations of inequity aversion by examining how it plays out in a real-world context in which self-interest motivations and competitive pressures are substantial. National Basketball Association games were examined and instances of obviously incorrect foul calls were identified. Players were found to make a substantially lower percentage of the foul shots they were awarded as a result of incorrect calls, indicating that they were troubled by the inequity. This drop-off in performance was only observed when the shooter's team was ahead, highlighting the trade-off between the two conflicting motives of self-interest (the desire to win) and inequity aversion. 相似文献

The present research investigated Lerner's (1970, 1980) just‐world theory by manipulating victim‐related factors in a scenario and measuring several possible strategies for dealing with the threat to participants' just‐world beliefs created by the victim's intense suffering. Participants read a story about a victim who varied in terms of his character (likeable vs. unlikeable) and behavioral responsibility for causing his accident (high vs. low). The general pattern of results showed that for the unlikeable low‐responsibility victim, the primary response to protect justice beliefs appeared to be character derogation; for the likeable high‐responsibility victim, the primary protective strategy appeared to be blame; and for the likeable low‐responsibility victim, the primary protective strategy appeared to be compensation. Implications for just‐world theory are discussed. 相似文献

NMDA receptor antagonists interfere with learning and memory in some tasks, but not others. Some recent accounts have suggested that tasks placing demands on working memory are those most likely to be affected, and the present study tested this hypothesis. The purpose of the study was to adapt a recently developed procedure designed to test working memory capacity, the olfactory memory span task, for use in behavioral pharmacology and to then determine the effects of the NMDA receptor antagonist, dizocilpine (MK801) on performance in this task. Rats were trained in a non-match-to-sample procedure under conditions in which they had to remember an increasing number of olfactory stimuli as the session progressed. Simple olfactory discrimination trials were interspersed to provide a performance control. Effects of dizocilpine (.03, .10, .17, .3mg/kg) were determined after stable performances were obtained. Rats were able to sustain stable performances on both the span and simple discrimination tasks with average spans of about 10 items. Accuracy declined as the number of stimuli to remember increased, and dizocilpine impaired accuracy in a dose-dependent and memory-load dependent fashion. The finding that the effects of dizocilpine interacted with the number of stimuli to remember is generally consistent with hypotheses linking NMDA receptors and working memory processes. 相似文献

Poor fear conditioning is a correlate of violent offending in adults, but there is no evidence concerning juvenile offenders. Our aim was to compare emotional learning in juvenile offenders and controls and establish whether crime rate is related to seriousness of emotional learning problems. To this end, emotional learning was assessed in 42 juvenile offenders by measuring skin conductance responding (SCR) during fear conditioning. Compared to controls, juvenile offenders showed lower conditioned SCRs to visual stimuli associated with a subsequent aversive stimulus and the magnitude of the SCR during fear acquisition was inversely associated with the number of their recorded offences. These findings suggest that juvenile offenders have impairments in the neural systems that subserve emotional learning. The implication is that using punitive measures to control persistent offenders is unlikely to be effective in an identifiable group of juvenile offenders. 相似文献

A cognitive complexity metric applied to cognitive development 总被引:7,自引:0,他引:7
Two experiments tested predictions from a theory in which processing load depends on relational complexity (RC), the number of variables related in a single decision. Tasks from six domains (transitivity, hierarchical classification, class inclusion, cardinality, relative-clause sentence comprehension, and hypothesis testing) were administered to children aged 3-8 years. Complexity analyses indicated that the domains entailed ternary relations (three variables). Simpler binary-relation (two variables) items were included for each domain. Thus RC was manipulated with other factors tightly controlled. Results indicated that (i) ternary-relation items were more difficult than comparable binary-relation items, (ii) the RC manipulation was sensitive to age-related changes, (iii) ternary relations were processed at a median age of 5 years, (iv) cross-task correlations were positive, with all tasks loading on a single factor (RC), (v) RC factor scores accounted for 80% (88%) of age-related variance in fluid intelligence (compositionality of sets), (vi) binary- and ternary-relation items formed separate complexity classes, and (vii) the RC approach to defining cognitive complexity is applicable to different content domains. 相似文献

The conceptual complexity of problems was manipulated to probe the limits of human information processing capacity. Participants were asked to interpret graphically displayed statistical interactions. In such problems, all independent variables need to be considered together, so that decomposition into smaller subtasks is constrained, and thus the order of the interaction directly determines conceptual complexity. As the order of the interaction increases, the number of variables increases. Results showed a significant decline in accuracy and speed of solution from three-way to four-way interactions. Furthermore, performance on a five-way interaction was at chance level. These findings suggest that a structure defined on four variables is at the limit of human processing capacity. 相似文献

During adaptation, two different letter strings (each five or six letters) were presented to subjects alternately, one in green and the other in magenta. The extent to which these letter strings subsequently elicited a color aftereffect was assessed. In different experiments, the chromatic letter strings consisted of words and nonwords. The results indicated that letter strings that form English words can contingently elicit a color aftereffect. This was the case even when the words were anagrams. There was no evidence that nonword letter strings could contingently elicit such an aftereffect, even when the nonwords conformed to English orthography. The results are relevant to understanding other contingent color aftereffects (McCollough effects), illusory color noted by computer operators who work at monochrome (green or amber) displays, and the processing of text. 相似文献
