In exemplar models of categorization, the similarity between an exemplar and category members constitutes evidence that the exemplar belongs to the category. We test the possibility that the dissimilarity to members of competing categories also contributes to this evidence. Data were collected from two 2-dimensional perceptual categorization experiments, one with lines varying in orientation and length and the other with coloured patches varying in saturation and brightness. Model fits of the similarity-dissimilarity generalized context model were used to compare a model where only similarity was used with a model where both similarity and dissimilarity were used. For the majority of participants the similarity-dissimilarity model provided both a significantly better fit and better generalization, suggesting that people do also use dissimilarity as evidence. 相似文献

This study was designed to investigate the effects of aging on consciousness in recognition memory, using the Remember/Know/Guess procedure (Gardiner, J. M., & Richarson-Klavehn, A. (2000). Remembering and Knowing. In E. Tulving & F. I. M. Craik (Eds.), The Oxford Handbook of Memory. Oxford University Press.). In recognition memory, older participants report fewer occasions on which recognition is accompanied by recollection of the original encoding context. Two main hypotheses were tested: the speed mediation hypothesis (Salthouse, T. A. (1996). The processing-speed theory of adult age differences in cognition. Psychological Review, 3, 403–428) and the executive-aging hypothesis (West, R. L. (1996). An application of prefrontal cortex function theory to cognitive aging. Psychological Bulletin, 120, 272–292). A group of young and a group of older adults took a recognition test in which they classified their responses according to Gardiner, J. M., & Richarson-Klavehn, A. (2000). Remembering and Knowing. In E. Tulving & F. I. M. Craik (Eds.), The Oxford Handbook of Memory. Oxford University Press. remember-know-guess paradigm. Subsequently, participants completed processing speed and executive function tests. The results showed that among the older participants, R responses decreased, but K responses did not. Moreover, a hierarchical regression analysis supported the view that the effect of age in recollection experience is determined by frontal lobe integrity and not by diminution of processing speed. 相似文献

With the high-amplitude sucking procedure, newborns were presented with two lists of phonetically varied Japanese words differing in pitch contour. Discrimination of the lists was found, thus indicating that newborns are able to extract pitch contour information at the word level. 相似文献

We investigated the order of acquisition of concepts and cognitive processes in children with emotional and behavioral difficulties and the extent to which these children show similarity to ordinary children in sequence and structure of development. Similarity in developmental sequence was strongly supported by scalogram analyses and has clear implications for organizing teaching, but similarity in structure was less clear. Cognitive processes, however, and the nature of the children's reasoning were clarified by the method of exploration used. This was particularly fruitful for providing insight into the difficulties children may have. The findings thus contribute to understanding with a view toward furthering concept development in children with emotional and behavioral difficulties. 相似文献

We explored how the sex role orientation of adult observers related to their perceptions of boys' and girls' aggression. Sex-typed and androgynous undergraduate subjects viewed videotaped scenes in which one member of a girl-boy pair behaved aggressively toward the other. Unlike androgynous subjects, sex-typed subjects judged boys' aggression to be more intentional than girls' and proposed more severe reprimands for aggressive boys than for aggressive girls. Androgynous subjects recommended more severe reprimands for aggressive girls than sex-typed subjects did. Overall, sex-typed subjects differed from androgynous subjects not in their assessment of the degree of aggressiveness boys and girls expressed, but in their perceptions of the purposefulness of boys' and girls' aggression and how harshly to respond to it. We speculated that sex-typed subjects did not consider girls' aggression to be serious enough to warrant severe reprimands. Thus, during socialization, sex-typed adults perhaps model less aggression in response to girls' aggressive acts than to boys'. In addition, sex-typed adults may convey to girls that their aggression is not an effective means of obtaining adult intervention. 相似文献

Reducing-augmenting, sensation-seeking and extraversion-introversion are discussed in the context of strength-of-the-nervous-system theory and two experiments are reported. Experiment 1 showed that high scorers on Vando's Reducer-Augmenter Scale (RAS) (stimulus-intensity reducers) may be identified with sensation-seeking, as measured by Zuckerman's Sensation-seeking Scale, and extraversion, as measured by the Eysenck Personality Inventory. Augmenters' electrodermal responses habituate more slowly than do those of reducers to a relatively strong stimulus. Reducers prefer loud music and apparently need fewer hours of sleep. Female reducers consume relatively more stimulant drinks than female augmenters. Reducers have significantly higher resting systolic blood pressure than augmenters, a finding that was confirmed in the second experiment. However, Experiment 2 failed to find the expected relationship between augmenting-reducing as determined by the RAS and performance on the Kinaesthetic Figural Aftereffects Test. 相似文献

Health defined as the psychophysiological capacity to act or respond appropriately in a wide variety of situations, is enhanced by many means other than preventing and treating disease and injury. Therefore no choice of a particular medical intervention is likely to maximize health for all people with (or at risk for) a given disease. As a result, if medical practitioners are to be fully competent in the sense of knowing not only how to perform procedures but when and when not to do so, they must be able to support patients (and those who know and care about them) in weighing all of the many factors which bear upon the decision as to which, if any, medical interventions are likely to improve the person's health. 相似文献

The development of a measure to assess vocational maturity in adults with delayed career development
Caroline A Manuele 《Journal of Vocational Behavior》1983,23(1):45-63
The development and validation of a measure of vocational maturity for educationally and economically “disadvantaged” adults who experience delayed career development is described. The Adult Vocational Maturity Assessment Interview (AVMAI) measures the attitudinal, cognitive, and behavior aspects involved in coping with exploratory and early entrance stage vocational development tasks. The measure employs a structured interview format accompanied by a detailed content scoring manual. It includes 120 items which yield scores for eight scales: Orientation to Education; Orientation to Work; Concern with Choice; Self-Appraisal: Interests and Abilities; Self-Appraisal: Personality Characteristics; Self-Appraisal: Values; Exploring Occupations; and Using Resources. Evidence for the measure's reliability, content, and construct validity is presented by examining the internal consistency of the scales, the reliability of its scoring procedures, its interscale correlations, and its performance in a pretest-post-test experimental situation. Research and counseling uses of the measure are discussed in the context of the need for vocational psychologists to develop and use measures that are appropriate for the specific career development problems of different groups in society. 相似文献

In order to determine the relation between hemispheric specialization for language and intellectual deficiency, two groups of lower-IQ subjects were compared to normal-IQ controls on word-dichotic listening tasks. Two conditions in which stimuli differed by their level of phonological complexity were used. Normal controls showed the expected right-ear advantage in both conditions. Moreover, they showed a greater magnitude of ear difference on the condition requiring higher-order phonological processing. In the mentally deficient group, almost half the subjects exhibited a left-ear advantage and they showed no difference between the two conditions in terms of the magnitude of ear difference. These results point to the presence of atypical hemispheric specialization in mentally deficient subjects. 相似文献

A series of experiments on children and adults were conducted to define the features and workings of argumentative discourse. Oral and written arguments were analyzed for the complexity of the argument support structure and the presence of typological argumentation markers (certainty modals, value judgments, etc.). Subjects were asked to assess the argumentativity of texts that did or did not contain typical argumentation markers. At about age ten, children can produce and recognize a ‘minimal argumentative structure,’ in which the speaker takes a stance and supports it with text that derives its argumentativity from the presence of this stance). However, full mastery of the negotiation process, that involves acknowledgment of the opponent's stance (generally through the use of counterarguments) is not present before the ages of 15 to 16. The minimal argumentative structure continues to develop with age and gain complexity. Certain situations are more conductive to the production of elaborate argumentative discourse, such as a genuinely controversial topic with an unfamiliar adult addressee whose stance is not known and whose reaction is thus unpredictable. Here speakers produce complex arguments while still leaving room for negotiation. Overall, certain argumentation markers can be identified in all argumentative text. these markers can be used to characterize stages of development of argumentative discourse. A number of issues remain unexplored, including: What other (implicit...) devices do speakers use to convince their audience? Why is the capacity to put argumentation in writing acquired at such a late stage of development? 相似文献
