Four experiments examined the extent to which prior knowledge influences the acquisition of category structure in unsupervised learning conditions. Prior knowledge is general knowledge about a broad domain that explains why an object has the features it does. Category structure refers to the statistical regularities of features within and across categories. Subjects viewed items and then divided them up into the categories that seemed most natural. Each item had one feature that was related to prior knowledge and five features that were not. The results showed that even this small amount of prior knowledge helped subjects to discover the category structure. In addition, prior knowledge enhanced the learning of many of the category's features, and not just the features that were directly relevant to the knowledge. The results suggest that prior knowledge may help to integrate the features of a category, thereby improving the acquisition of category structure. 相似文献

This essay addresses three problems facing a physicalist (as opposed to dualist) account of the person. First, how can such an account fail to be reductive if mental events are neurological events and such events are governed by natural laws? Answering this question requires a reexamination of the concept of supervenience. Second, what is the epistemological status of nonreductive physicalism? Recent philosophy of science can be used to argue that there is reasonable scientific evidence for physicalism. Third, the soul has traditionally been seen as that which enables human beings to relate to God. What accounts for this capacity in a physicalist theory of the person? This essay argues that the same faculties that enable higher cognitive and emotional experience also account for the capacity for religious experience. 相似文献

Deficit in olfaction and remote nonolfactory memory in Alzheimer's disease (AD) motivated the present study of remote memory for odors and faces, operationally defined as rated familiarity, in patients with AD and controls. Uncommon engineering symbols were rated for familiarity to ensure task comprehension. Results showed that patients with AD rate odors, but not faces, as significantly less familiar than do controls, which is indicative of deficit in remote odor memory. Follow-up testing 1 year later again showed this result. Poor odor-detection sensitivity in patients, with AD, but lack of significant correspondence between sensitivity and familiarity, suggests an existing but limited effect of sensitivity on familiarity. The findings provide further evidence that olfaction may be a useful modality for early identification of AD. 相似文献

Though multiculturalists focus on race and minority status, issues of central importance to the aged, multiculturalism has not infiltrated the gerontology literature. However, since the so-called natural stages of life are cultural formations, each one a valuable creation, the topic of aging would certainly benefit from a connection to multiculturalism and its critique of the demands of assimilation. 相似文献

Ian Barbour has distinguished eight theologies of God's role in nature, together with corresponding models of divine activity. This essay examines these ideas in the light of a theology of the cross. Three of Barbour's approaches—the neo-Thomist, the kenotic, and the existentialist—are able to provide different aspects of a theology of divine action that is consistent with belief that God's definitive revelation takes place in the Crucifixion and Resurrection of Jesus of Nazareth. These approaches encourage attention to a part of traditional doctrines of Providence, the idea that God acts by "cooperation" with natural processes. The kenotic character of divine involvement in the world means that the regularities of the basic interactions of physics are maintained. The idea of cooperation can be extrapolated into the past, to give some insight into ways of understanding God's activity in originating the universe. 相似文献

Using a broad-based measure of normal personality, we tested the hypothesis that the trait conscientiousness is the best single predictor of scores on two well-researched integrity tests. Data from 180 traditional and nontraditional college students provided clear support for this hypothesis, but also indicated that a number of traits other than conscientiousness were likely to be related to integrity test scores. Scores on all six of the primary scales, and 33 of the 45 homogeneous item clusters (HICs) of the Hogan Personality Inventory were related to scores on the PDI Employment Inventory and/or the Personnel Selection Inventory. Personality variables were better predictors of scores on the PDI Employment inventory, which is a veiled-purpose (also referred to as personality based) test, than of scores on the Personnel Selection Inventory, which measures honesty-related attitudes and includes items calling for direct admissions of misdeeds.We are grateful for the assistance and cooperation of London House Inc., Personnel Decisions Inc., and Hogan Assessment Systems, Inc., and especially to Scott Martin, George Paajanen, and Joyce Hogan. 相似文献

Previous research indicates that vasopressin-containing (LE) rats are capable of adapting to the stress of food restriction,
whereas vasopressin-deficient (DI) rats cannot adapt to this stressor. It has been postulated that abnormalities in glucose
metabolism may be one of the factors leading to the demise of food-restricted DI rats. The present study was conducted to
determine if taste preferences are altered in DI animals and if the presentation of exogenous glucose, in the form of sucrose
solutions, can ameliorate the effects of the stress of food restriction. Four different concentrations of sucrose solutions
were presented to LE and DI rats under the food-restricted condition. In both strains, an 8% sucrose solution was preferred
over 0%, 16%, and 32% concentrations, with DI rats consuming more of this concentration than LE rats. Thus, when DI rats had
the opportunity of maintaining glucose homeostasis by exogenous supplements, they maintained body weight, displayed no stomach
pathology, and survived. 相似文献

Psychological research on the pupillary response since 1960 has focused on an arousal interpretation and a cognitive interpretation. Experiment 1 was an attempt to manipulate some arousal factors while controlling the cognitive demands of the task. Pupil size was cinematographically recorded while subjects who had different degrees of reported fear of snakes listened to passages describing imagined interactions with a snake in different proximities. There was also a set of control passages that made no mention of snakes but were otherwise semantically and syntactically identical to the aversive passages. The pupillary response showed no influence of the arousal manipulations, but rating and behavioral data indicated that the arousal variables had been effective. The cognitive demands of the task were clearly indicated by the pupillary response. In Experiment 2 two types of tasks were used: one that employed both arousal (incentive) and cognitive factors and another that had an arousal manipulation (threat of shock) but no explicit cognitive demands. The pupil response was recorded as well as heart rate, skin conductance, and EMG. The pupillary response showed an effect of the arousal manipulations only when cognitive demands were minimal. The results of both experiments are consistent with the view that cognitive demands take priority over arousal factors in affecting the pupillary response. Heart rate did show arousal effects that were not preempted by cognitive demands. 相似文献
