When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons. 相似文献

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing. 相似文献

The primary objective was to compare the MMPI-2 profiles for professional job applicants with corresponding profiles on the original MMPI. Male and female MMPI-2 profiles were also compared, and correlational and factor analyses were used to examine: A) Interscale correlations vis-à-vis item overlap, and B) The impact of K-corrections. The subjects were 82 auditor applicants, plus 212 sales and management applicants from an earlier study. The original MMPI was found to overpathologize applicant profiles. Male and female MMPI-2 profiles differed only on Mf. Scales L, K, and Hy formed a favorable cluster for job applicants, while F, Hs, Pt, Sc formed one unfavorable cluster—and D, Si a second. K-corrections consistently moved clinical scales in the direction of the favorable cluster. 相似文献

The primary purpose of this study was to examine whether empirically derived cluster profiles based on scores from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) predicted outcomes of surgery at 1 year for patients with low-back pain. On the basis of hierarchical cluster analysis of presurgery MMPI-2 scores for 60 patients, three interpretable and significant subgroups were formed. These consisted of a pathological/neurotic type, a double V-code type, and a normal type. The patents in the normal type were significantly more likely to report beneficial outcomes of surgery in terms of disability and pain than those in the other 2 types. These findings extend previous research and suggest (1) low-back surgery candidates are heterogeneous in their psychological profiles, and (2) MMPI-2 profiles are predictive of low-back surgery outcome. Future research should focus on identifying physiological substrates for these distinct profiles and investigating the effectiveness of presurgical psychological interventions based on profile type. 相似文献

Social interactions are fostered by humans’ propensity to compute their partner’s perspective online. However, due to the mindreading system’s limited capacity perspective taking (PT) was argued to occur spontaneously only for level-1, but not level-2 perspectives. We propose that level-2 perspectives (containing aspectual information) can also be computed spontaneously if participants have reason to assume that the partner is indeed aware of the objects’ aspectual properties. Pairs of adult participants took part in the modified version of Surtees, Butterfill, and Apperly’s (2012) number verification paradigm. Participants had prior information on their partner’s task, which either called for processing aspectual properties or did not. The partner’s inconsistent perspective was found to interfere with RT-s providing evidence for spontaneous level-2 PT. However, such interference only occurred when the partner’s task involved processing the perspective dependent object feature, suggesting that PT was sensitive to the other’s awareness of the to be represented information. 相似文献

A patient with sarcoidosis involving predominantly the hypothalamus and fornices was evaluated for dementia. He showed a relative sparing of fund of knowledge and orientation. Memory skills, particularly short-term memory, were severely impaired. Behavioral changes included apathy and a lack of spontaneity. Insight was relatively preserved. The pattern of his deficits showed some similarities to the pattern reported in patients with Huntington's disease and was different from that described in Alzheimer's disease. The dementia caused by subcortical pathology may differ in important respects from that caused by diffuse cortical dysfunction. 相似文献

Whether “psychometric” and “Piagetian” kinds of intelligence, as measured by instruments designed to measure these constructs, are the same or different is regarded as a question of whether they have the same or different courses of development with age. While factor analysis may not be fully adequate for investigation of this question, use of this technique with variables reflecting chronological age variation must involve elimination of the age effect in order to assess relations among the constructs measured. Humphreys and Parsons (1979) were justified in partialing out age in their reanalysis of a study by Stephens, McLaughlin, Miller, and Glass (1972), to show that the two constructs are highly correlated and possibly identical in the sample studied. Reanalyses of studies by DeVries and Kohlberg (1977) and by DeVries (1974) yield somewhat conflicting results on the identity between psychometric and Piagetian intelligences. The former study does not yield a convincing separation between them, whereas the latter suggests that they can be distinguished, though substantially correlated and both loaded with a general factor. Problems in further investigating the issue are discussed. 相似文献

Twenty normal, twenty left-, and fifteen right-brain injured subjects, all right-handed, were assigned a sequence of voluntary inhibition of 23 movements. The inhibition lapse was recorded. Statistical analyses indicated a high performance in the normal and a deficient performance in left-brain injured subjects, no influence of the neurological symptoms on groups' achievement, a handicap in the subjects affected by a frontal lesion in the right brain, a hierarchical clustering of items varying according to the groups, and an organ-group interaction. 相似文献
