Natural concepts in a juvenile gorilla (gorilla gorilla gorilla) at three levels of abstraction 下载免费PDF全文
The extent to which nonhumans are able to form conceptual versus perceptual discriminations remains a matter of debate. Among the great apes, only chimpanzees have been tested for conceptual understanding, defined as the ability to form discriminations not based solely on simple perceptual features of stimuli, and to transfer this learning to novel stimuli. In the present investigation, a young captive female gorilla was trained at three levels of abstraction (concrete, intermediate, and abstract) involving sets of photographs representing natural categories (e.g., orangutans vs. humans, primates vs. nonprimate animals, animals vs. foods). Within each level of abstraction, when the gorilla had learned to discriminate positive from negative exemplars in one set of photographs, a novel set was introduced. Transfer was defined in terms of high accuracy during the first two sessions with the new stimuli. The gorilla acquired discriminations at all three levels of abstraction but showed unambiguous transfer only with the concrete and abstract stimulus sets. Detailed analyses of response patterns revealed little evidence of control by simple stimulus features. Acquisition and transfer involving abstract stimulus sets suggest a conceptual basis for gorilla categorization. The gorilla's relatively poor performance with intermediate-level discriminations parallels findings with pigeons, and suggests a need to reconsider the role of perceptual information in discriminations thought to indicate conceptual behavior in nonhumans. 相似文献

Crossed aphasia: an analysis of the symptoms,their frequency,and a comparison with left-hemisphere aphasia symptomatology 总被引:4,自引:0,他引:4
This study presents a thorough analysis of published crossed aphasia (CA) cases, including for the first time the cases published in Japanese. The frequency of specific symptoms was determined, and symptomatology differences based on gender, familial sinistrality, and CA subtype were investigated. Results suggested that the CA population is comparable to the left-hemisphere patient population. However, male were significantly more likely than female CA subjects to show a positive history of familial sinistrality. Typical right-hemisphere (i.e., nonlanguage-dominant) symptoms were frequent but rarely carefully reported or assessed. Results are compared with previous CA reviews and left-hemisphere aphasia. Suggestions for a more systematic assessment of the CA symptomatology are presented. 相似文献

A three-factor model of personality pathology was investigated in a clinical sample of 183 female patients in an outpatient eating disorders treatment program. Cluster analysis of MCMI-II personality scales (Millon, 1987) yielded three distinct personality profiles, which were consistent with previous studies. First, 16.9% of the sample comprised a High Functioning cluster, which manifested no clinical elevations on the MCMI-II and had significantly lower scores on the Eating Disorder Inventory (EDI; Garner; 1991) scales than the other two clusters. Second, 49.1% of the sample comprised an Undercontrolled/Dysregulated cluster. Finally, the remaining 34% of the sample comprised an Overcontrolled/Avoidant cluster. This final cluster had significantly higher EDI Ineffectiveness scale scores than the Undercontrolled/Dysregulated cluster group. Cluster membership was not associated with eating disorder subtype, suggesting that there is considerable variance in personality pathology within eating disorder diagnostic categories. 相似文献

In this study, we examined the nature of infants’ representations of newly encountered word forms. Using a word–object association task, we taught 14-month-olds novel three-syllable words differing in segments and stress patterns. At test, we manipulated the stress pattern of the word or the position of the stressed syllable in the word. Our findings reveal that young infants store the stress information about the word, including the position in which the stressed syllable occurs, suggesting that infants form prosodically rich lexical representations of newly encountered words. 相似文献

The recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions (Experiment 1) as well as differently-valenced emotions (Experiment 2) conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we found evidence for a context effect on accuracy only in Experiment 1. This demonstrates that affective theory of mind inferences made at the pragmatic level of a text can automatically, contextually influence the perceptual processing of emotional facial expressions in a separate task even when those emotions are of a distinctive valence. Thus, our novel findings suggest that language acts as a contextual influence to the recognition of emotional facial expressions for both same and different valences. 相似文献

The Goal of Biological Parenthood and Emotional Distress From Infertility: Linking Parenthood to Happiness 总被引:1,自引:0,他引:1
This study examined the relationship between construals of the parenthood goal and emotional reactions to fertility difficulties. Mcintosh and Martin's (1992) goal linkage model predicts that individuals experiencing fertility difficulties who strongly link biological parenthood to happiness (i.e., those who strongly believe that having a biological child is necessary for happiness and life satisfaction) will ruminate more about this unfulfilled goal than will individuals who engage in less linking. The model also predicts that greater rumination leads to greater emotional distress and that rumination will mediate the relationship between linking and emotional distress. To examine these hypotheses, 69 women experiencing difficulty conceiving completed questionnaires that assessed linking, rumination, and emotional distress. Results support the hypotheses from the goal linkage model: Linking predicted rumination, rumination predicted emotional distress, and rumination mediated the relationship between linking and distress. 相似文献

Dietary behaviours, dietary attitudes, dietary knowledge and personality were surveyed in a group of 451 Scottish schoolchildren aged 11–15 years. A factor analysis of the behaviour items gave a three-factor structure with factors designated Healthy Eating, Unhealthy Eating and Health Habits. A general healthy vs. unhealthy eating factor was also extracted. A factor analysis of the attitude statements gave factors designated Pickiness, Neophobia and Food Interest. Dietary knowledge was found to be positively correlated with Healthy Eating score and negatively correlated with Unhealthy Eating score. The personality trait of Psychoticism was positively correlated with Unhealthy Eating score and negatively correlated with dietary knowledge, whilst Neuroticism was significantly negatively correlated with Healthy Eating and Health Habits and significantly positively correlated with Pickiness and Neophobia. Gender and socio-economic status differences in behaviour and attitude factor scores are also reported. 相似文献

Shared decision making between patients and providers is becoming increasingly common, particularly when there is no clear preferred course of action. As a result, decision aids are being adopted with growing frequency and have been applied to many medical decision-making issues. One such issue where there is uncertainty is breast cancer risk management among BRCA1/BRCA2 carriers. We present the development of a CD-ROM decision aid to facilitate risk management decision making in this population. Our decision aid was developed with the intention of providing it through a randomized clinical trial. The CD-ROM is a multimedia, interactive intervention which provides information about breast cancer, risks associated with BRCA1 and BRCA2 mutations, risk management options for hereditary breast cancer, and a breast cancer risk management decision aid. The goal of this CD-ROM, offered as an adjunctive intervention, is to reduce decisional conflict and psychological distress and improve comprehension of risk information, decisional satisfaction, medical adherence, and quality of life for this population of women at increased risk for breast cancer. 相似文献

This research provides evidence for a new moderator of the endowment effect: having a memento of the endowed object. Three studies adapting classic endowment effect paradigms and using a variety of endowment objects and mementos demonstrate that having a memento of an endowment increases willingness to trade the endowment and decreases selling prices for the endowment. We provide evidence that mementos attenuate the endowment effect regardless of whether the memento is a separate small gain when facing the loss of the endowment or a small part of the original endowment that is kept. Examining mementos in context of the endowment effect not only provides insight into the psychology underlying the reluctance to part with one's endowment but also other consumer disposition behaviors. 相似文献
