The Qolla Indians have high rates of involvement in agonistic forms of interaction. In previous reports the author suggested that ecological and physiological factors are causally associated with intracommunity differential participation in aggressive behavior. The present article described tests of hypotheses using other variables to explain this behavioral differentiation. The hypothesis that aggressiveness and participation in litigation are a function of the amount of social support the individual can potentially mobilize is tested. The relationships between indicators of social status (wealth, education, age, political activities, and ritual participation), on the one hand, and aggressiveness and litigiousness, on the other, also are examined.  相似文献

This presentation, written ten years after the American Psychoanalytic Association adopted a nondiscrimination policy with regard to sexual orientation, discusses the evolving relationship between psychoanalysis and homosexuality. The paper is in three sections: (1) the process of policy change and the overturning of injustice; (2) the excursion after Freud's death into analytic bias and extreme pathologizing of homosexuality, the struggle to overcome those distortions, and the lessons to be learned from this history; and (3) the search, in the coming decade, for new understanding of homosexuality and all aspects of sexuality.  相似文献

Six experiments based on visual preference procedures were conducted to examine gender categorization of female versus male faces by infants aged 3 to 4 months. In experiment 1, infants familiarized with male faces preferred a female face over a novel male face, but infants familiarized with female faces divided their attention between a male face and a novel female face. Experiment 2 demonstrated that these asymmetrical categorization results were likely due to a spontaneous preference for females. Experiments 3 and 4 showed that the preference for females was based on processing of the internal facial features in their upright orientation, and not the result of external hair cues or higher-contrast internal facial features. While experiments 1 through 4 were conducted with infants reared with female primary caregivers, experiment 5 provided evidence that infants reared with male primary caregivers tend to show a spontaneous preference for males. Experiment 6 showed that infants reared with female primary caregivers displayed recognition memory for individual females, but not males. These results suggest that representation of information about human faces by young infants may be influenced by the gender of the primary caregiver.  相似文献

This paper is an attempt to analyse some of the features of obsessional neurosis in terms of learning theory. First, the syndrome is described and found to have three main features: brooding, strong impulses to do unacceptable things, and ritualistic, defence-substitute activities. Second, the classical psychoanalytic explanation of the etiology of obsession is reviewed. This theory locates the source of conflict in the anal stage, but fails to give a satisfactory account of the precipitating conditions and of the cause for the persistence or fixation of the neurotic responses. In the third section both the precipitating conditions and the fixation conditions are analysed in terms of factors shown to be operative in animal learning experiments.  相似文献

Three conditioned taste aversion experiments with rats investigated superconditioning. In each experiment, alternate exposures of 2 flavor compounds with a common element (i.e., AB/AS) were administered to establish an inhibitory relationship between the 2 unique elements, B and S, and prior to testing, S was paired with lithium chloride (LiCl). In Experiment 1, pairings of a neutral cue (X) with S in compound with B after the AB/AS exposures resulted in superconditioning between X and S. Extinction of the common element (A) just before the S-LiCl pairing attenuated both the inhibitory relationship between B and S (Experiment 2) and superconditioning between X and S (Experiment 3). These observations suggest that superconditioning consists of enhanced performance rather than enhanced associative acquisition.  相似文献

In the analysis of stimulus competition in causal judgment, 4 variables have been frequently confounded with respect to the conditions necessary for stimuli to compete: causal status of the competing stimuli (causes vs. effects), temporal order of the competing stimuli (antecedent vs. subsequent) relative to the noncompeting stimulus, directionality of training (predictive vs. diagnostic), and directionality of testing (predictive vs. diagnostic). In a factorial study using an overshadowing preparation, the authors isolated the role of each of these variables and their interactions. The results indicate that competition may be obtained in all conditions. Although some of the results are compatible with various theories of learning, the observation of stimulus competition in all conditions calls for a less restrictive reformulation of current learning theories that allows similar processing of antecedent and subsequent events, as well as of causes and effects.  相似文献

Cognitive dysfunction, a common feature of multiple sclerosis (MS), frequently leads to impaired activities of daily living, social skills deficits, diminished social support, and unemployment. There is growing evidence indicating that cognitive impairment is amenable to the effects of medication and behavioral counseling. Unfortunately, routine neuropsychological testing is rare in MS clinics because screening is ineffective and testing strategies are often too cumbersome or expensive. Recent research supports the reliability of a brief screening test called the Multiple Sclerosis Neuropsychological Screening Questionnaire as well as a minimal neuropsychological battery called the Minimal Assessment of Cognitive Function in Multiple Sclerosis. Data indicate that the Multiple Sclerosis Neuropsychological Screening Questionnaire has excellent split-half and test-retest reliability, and that it predicts neuropsychological deficiency with good sensitivity and specificity. Recently acquired data also show that the Minimal Assessment of Cognitive Function in Multiple Sclerosis tests have good test-retest reliability, discriminate MS patients from normal controls, and predict unemployment in MS patients. Thus, these or similar methods should be employed for the routine monitoring of cognitive functioning of MS patients.  相似文献
