This study was designed to provide a basis to understand better antifeminine stereotyped attitudes that occur in association with a stimulus no more informative about a person than her first name. College students, mostly freshmen and sophomores, ascribed connotative meanings to common and uncommon masculine and feminine first names while imagining either real or ideal persons. The results from 48 subjects disclosed that the semantic dimension of potency (e.g., strength and bravery) is likely to be a fundamentally important connotation associated more with masculine names than with feminine names. Two findings very much supported this conclusion. Thus, the potency dimension was the only one of five dimensions of semantic meaning that: (a) yielded any masculine-feminine difference in the ideal condition, and (b) showed a disfavorable connotation for feminine names in comparison to masculine names in either the real or ideal condition. 相似文献

The responses of school psychologists concerning the secondary school counselor's role differ from those of counselor educators and counselors in many respects and seem to reflect a tendency toward role differentiation. In the actual school situation, the roles of these two groups overlap in some areas. The tendency of school psychologists was to emphasize activities of counselors which did not overlap with theirs and to define the counselor's role in these terms. If school counselors were polled concerning their attitudes toward the role of the school psychologist, it is probably that the same tendency toward role differentiation would be found.
These results point to the possibility that friction between these two groups may stem from difficulties in role perception. To improve communication, the unique contributions of both groups should be stressed. On the other hand, where activities overlap, it should not be assumed that the performance of such activities by one group excludes the other group from making a contribution in similar activities. 相似文献

The prototype effect in face recognition: Extension and limits 总被引:2,自引:0,他引:2
The prototype effect in face recognition refers to a tendency to recognize the face corresponding to the central value of a series of seen faces, even when this central value or prototype has not been seen. Five experiments investigated the extension and limits of this phenomenon. In all the experiments, participants saw a series of faces, each one in two or more different versions or exemplars, and then performed a recognition test, including seen and unseen exemplars and the unseen prototype face. In Experiment 1, a strong prototype effect for variations in feature location was demonstrated in oldness ratings and in a standard old/new recognition test. Experiments 2A and 2B compared the prototype effect for variations in feature location and variations in head angle and showed that, for the latter, the prototype effect was weaker and more dependent on similarity than for the former. These results suggest that recognition across feature variations is based on an averaging mechanism, whereas recognition across viewpoint variations is based on an approximation mechanism. Experiments 3A and 3B examined the limits of the prototype effect using a face morphing technique that allows a systematic manipulation of face similarity. The results indicated that, as the similarity between face exemplars decreases to the level of similarity between the faces of different individuals, the prototype effect starts to disappear. At the same time, the prototype effect may originate false memories of faces that were never seen. 相似文献

Space constancy (the perception that the world remains stable despite eye movements) might be mediated by receptive fields
with constant locations in the world rather than constant locations on the retina. In a strong form the hypothesis, receptive
fields of single neurons would compensate for all eye movements, whereas in a weak form they would compensate only for the
small movements of fixation that occur without retargeting. Early receptive field mapping confounded world-centered and retina-centered
organizations by fixing the retina relative to the world. This paper links the strong and weak forms of constancy by relating
previously isolated data, and illustrates the issues with a previously unpublished figure showing that striate receptive field
have constant retinal locations. The first tests of space constancy in striate cortex contradicted the strong hypothesis;
recent tests contradict the weak hypothesis, also. The results are consistent with modern theories of space constancy, differentiating
between motor-oriented and perceptual functions of vision, and differentiating between constancy during pursuit and constancy
across saccades.

This study's purpose was to extend the distantresearch on gender roles. The specific objective was tobetter understand the gender role of male psychologists.It was hypothesized that male psychologists would exhibit an androgynous gender role.Gender role styles in professional work and in thepersonal realm were assessed. Questionnaire packets weremailed to 300 male clinical psychologists affiliated with the American Psychological Associationacross six regions within the United States. Sixty ofthe 61 participants reported being Caucasian and 1reported being Native American. Being that the sample was that of practicing psychologists, all withdoctorate degrees, the social class is presumed to be atleast upper middle class. The packets contained ademographics questionnaire and two Personal Attributes Questionnaires. Results suggest that malepsychologists do exhibit an androgynous gender role inboth professional and personal realms. A great deal ofthe prior literature indicates that androgynoustherapists have more adaptive communication skills and arebetter at assessing and treating their clients. Thisresult is therefore advantageous to therapeuticoutcomes. 相似文献

A System for Relational Reasoning in Human Prefrontal Cortex 总被引:7,自引:0,他引:7

The integration of multiple relations between mental representations is critical for higher level cognition. For both deductive- and inductive-reasoning tasks, patients with prefrontal damage exhibited a selective and catastrophic deficit in the integration of relations, whereas patients with anterior temporal lobe damage, matched for overall IQ but with intact prefrontal cortex, exhibited normal relational integration. In contrast, prefrontal patients performed more accurately than temporal patients on tests of both episodic memory and semantic knowledge. These double dissociations suggest that integration of relations is a specific source of cognitive complexity for which intact prefrontal cortex is essential. The integration of relations may be the fundamental common factor linking the diverse abilities that depend on prefrontal function, such as planning, problem solving, and fluid intelligence. 相似文献

Freezing (immobility) in the presence of aversive stimuli is a species-specific behavior that is used as an operational measure of fear. Conditioning of this response to discrete sensory stimuli and environmental context cues has been used as a tool to study the neuropsychology of memory dynamics and their development over the lifespan. Three age groups of F344 rats (3, 9, and 27 month) received tone–foot shock pairing (or tone only) in a distinctive chamber on two consecutive days. Separate subgroups of rats from each age group were then tested, at retention intervals of 1, 20, 40, or 60 days, for context-mediated fear in the environment in which they were trained, for generalization of the fear response to a novel chamber, and for fear of the tone. Beginning at day 20, the 27-month-old rats exhibited less freezing behavior than did younger rats when tested in the conditioning context. This age difference was a result of freezing behavior becoming progressively stronger with time in the two younger age groups, a phenomenon that has been referred to as memory incubation. Incubation of the contextual fear response was not detected in the old rats. In a novel context, all age groups exhibited significantly more freezing than did control animals. There was also pronounced incubation of this generalized freezing response, and the extent of incubation declined significantly with age. In the novel context, the freezing response to the tone was robust in all age groups and increased over time, in constant proportion to the degree of freezing elicited by the novel context itself, prior to tone onset. The fact that old animals are known to be relatively selectively impaired in forms of memory that depend on a functional hippocampus suggests a possible explanation for the reduced incubation effects seen in old rats; however, whether the increased expression of fear over time is mediated by a hippocampal-dependent memory consolidation process or whether it reflects a generalized increase in the gain of the circuitry mediating the fear response itself, remains to be determined. 相似文献

Research has shown that servers can increase their tip percentages by writing "Thank you" or by drawing a happy face on the backs of customers' checks. In the current study, a third approach of this type was tested. An experiment was conducted in which a female server either did or did not write a helpful message about an upcoming dinner special on the backs of checks before delivering them to customers. It was predicted that adding the helpful message would increase tip percentages because of reciprocity, in which customers would tend to respond to the server's "tip" with an increased tip of their own. Results were consistent with this prediction: Mean tip percentages increased from about 17% to 20%. 相似文献

Understanding covert recognition 总被引:1,自引:0,他引:1
An implementation of Bruce and Young's (1986) functional model of face recognition is used to examine patterns of covert face recognition previously reported in a prosopagnosic patient, PH. Although PH is unable to recognize overly the faces of people known to him, he shows normal patterns of face processing when tested indirectly. A simple manipulation of one set of connections in the implemented model induces behaviour consistent with patterns of results from PH obtained in semantic priming and interference tasks. We compare this account with previous explanations of covert recognition and demonstrate that the implemented model provides the most natural and parsimonious account available. Two further patients are discussed who show deficits in person perception. The first (MS) is prosopagnosic but shows no covert recognition. The second (ME) is not prosopagnosic, but cannot access semantic information relating to familiar people. The model provides an account of recognition impairments which is sufficiently general also to be useful in describing these patients. 相似文献
