Differences in the ability of young adults and elderly to recognize faces were examined under two conditions. In a standard single-view condition, in which each input face was shown as one photograph, we confirmed prior findings that young adults perform better than the elderly at distinguishing photographs seen before from photographs of new faces. We also found that the elderly had more trouble distinguishing photographs seen before from photographs of(l) old faces changed in facial expression and (2) old faces changed in expression and pose. Yet there were no reliable age differences in distinguishing old-but-changed faces from entirely new faces. In a more naturalistic multi-view condition, in which each input face was shown in four poses and with two expressions, no age differences were found. A second experiment ruled out the possibility that varied repetition, by itself, removes age differences in recognizing faces. These data supported age differences in remembering facial expressions and possibly other details of photographs of faces, but not in remembering faces perse. 相似文献

Sexual harassment has increasingly come to be recognized as a major problem confronting working women. Utilizing the results of a survey of women in traditional male occupations (N=160), this paper summarizes some new data on the amount, type, and sources of harassment experienced by this group. Interpreting these findings within the content of the larger theory of patriarchy, it also identifies and provides further clarification of some individual and organizational correlates of harassment. The data offer provisional support for recent theoretical claims that women in male-defined occupations occupy a particularly problematic position vis-`a-vis men. Over 75% of the respondents reported experiencing at least one form of harassment as compared to the 50% + generally cited for the population as a whole. Consistent with the general cultural patterns of sexual violation, incidence of harassment was found to be inversely related to the level of severity. Probably predicated at least partially on opportunity structure, peers were cited as the most frequent source of harassment, followed by supervisors, subordinates and clients. A number of individual correlates of harassment were also identified. As expected, married workers and older respondents reported lower levels of harassment. A curvilinear relationship was found to exist between length of employment and harassment. Finally, respondents who were employed as managers and engineers reported approximately equal levels of harassment, while those in the professions such as the sciences, computers, public administration, etc., reported significantly lower levels of harassment. Consistent with the thesis of organizational culpability in the prevalence and persistence of sexual harassment, individuals employed in firms perceived to have high equal employment opportunity for women reported significantly lower levels of harassment than those in firms with low opportunity. 相似文献

Training to become a marriage guidance counsellor in Scotland involves a relatively demanding 18 months' programme of both didactic and experiential learning. Changes in the counsellors' marital relationships following training were evaluated using the Marital Adjustment Test and two ad hoc questionnaires. Of the 49 counsellors who (a) began training between 1976 and 1980, (b) completed the training and (c) were still counselling in February 1983, 33 participated, as did 30 of their partners. In general, the counsellors and their partners reported increased marital satisfaction following the training period, though five counsellors and two partners reported a decrease. The findings from the ad hoc questionnaires were also encouraging. 相似文献

The literature reviewed here demonstrates that spousal response to pain display can reinforce and thereby perpetuate the patient's pain behavior. Relationships characterized as sick-role homeostatis reflect a nexus of behavioral contingencies which are highly resistant to treatment. Though such relationships could developde novo subsequent to accident or injury, modeling and familial effects in chronic pain suggest a rich personal and family history of chronic pain learning experiences. Spousal reinforcement of pain behavior is greater in satisfied relationships and tends to involve contingent attention and caring rather than assistance or taking over tasks and chores. As the vast majority of pain patients and spouses report being satisfied with their marriages, spousal involvement in chronic pain treatment is critical. 相似文献

A procedure is described which disrupts response-reinforcer contiguity and response dependency and which demonstrates how the location of the response dependency in interval schedules can be regarded as a controlling variable in its own right. Rats' lever pressing produced sucrose on a recycling conjunctive fixed-time 30-second fixed-ratio 1 schedule of reinforcement. Reinforcement occurred only at the end of the fixed-time component on this schedule and only if a response had occurred during that component. This produced a pause-respond-pause pattern during the interreinforcer interval for all animals. When the location of the response dependency was then restricted to a 10-second period in the middle of the fixed-time component, the pattern was accentuated and response rates increased for all animals, while postreinforcement pauses decreased sharply for two animals. When responding was required in the first 10 seconds of the fixed-time component, responding peaked earlier in the interval for all animals. Response rates were slightly below those in the previous conditions, while postreinforcement pauses were between 2 and 6 seconds across animals. 相似文献

Infant perception of a Michottean launching event in which one object causes another to move through collision is examined in a series of habituation-test experiments. A number of hypotheses concerning how infants aged around 30 weeks might perceive and encode launching and its noncausal variants are identified and tested. The results of the first experiment indicate that infants can perceive direct launching as an event with internal structure, that is, as composed of two temporally ordered movements. The nature of the encoding by the infants is perceptual and not specifically motor-based. The second experiment makes it seem unlikely that the infants encode independent spatial and temporal features (for example, contact and successivity), while the third experiment suggests a spatiotemporal continuity gradient. Some implications for the origins of causality are discussed. 相似文献

An examination was made of the following research questions: (a) Do Irish homosexuals and heterosexuals differ in the frequency of their classification in sex-role categories? (b) Is sexual orientation related to psychological adjustment? (c) Is androgyny related to psychological adjustment? Subjects were 112 Irish men and women who were administered Bem's Sex-Role Inventory, Rosenberg's Self-Esteem Scale, Zung's Self-Rating Depression Scale, and a questionnaire. Results indicated that Irish homosexuals were classified more frequently than Irish heterosexuals as androgynous. Homosexuals did not differ from heterosexuals in self-esteem or depression scores. Among these Irish subjects, psychological sex-role category is a more powerful influence on psychological health than actual sexual orientation. It is not whether you are homosexual or heterosexual that affects your psychological health, but how you perceive your own psychological masculinity and femininity. 相似文献

Many jurisdictions across North America have revised their statutes pertaining to the criteria for civil commitment with the legislative intent to either increase or decrease the use of involuntary hospitalization. The impact of these revised statutes has been examined in many jurisdictions, but there has been no consensus regarding their effectiveness in changing the rates of involuntary admissions. The present article reviews the literature from a methodological perspective, comparing the differing analyses, results and interpretations. When the legislative revision has sought to expand medical prerogative, results indicate a sustained increase in civil commitments. When legislation has aimed at limiting medical discretion, there was an immediate decline in civil commitment rates, but a subsequent increase in the period following the initial post-reform declines. These results are discussed in terms of readmission trends, deinstitutionalization, and the possible reaction of mental health professionals who perceive legislation as an unnecessary constraint in the treatment of the mentally ill. 相似文献

The purpose of these studies was to explore the role of effort in remembering anagrams and their solutions. In Experiment 1, we compared the effects on memory of copying words, typing them as solutions for easy anagrams, or typing them as solutions for difficult anagrams. Solving anagrams involved more effort than did simply typing words, as indexed by response time. However, this effort facilitated recall for solutions to easy anagrams but not for solutions to difficult anagrams. In Experiment 2, we compared memory for anagrams and their solutions using a frequency-judgment task. Memory for solutions was better than memory for anagrams, and this difference was not affected by anagram difficulty. The results of these studies have implications for our understanding of the role of effort in remembering. 相似文献
