Summary Young and elderly adults acquired route information from a sequence of slides depicting a walk through an actual environment. The accuracy of their distance knowledge after viewing the slides was compared for a normal presentation and a presentation with temporospatial discontinuity. No differences between age groups were noted under normal presentation conditions, but young adults were more accurate under conditions of temporospatial discontinuity. Results were interpreted in terms of an age-related decrement in the operational capacity of working memory. They were also viewed as supportive of a constructivist-representational theory of spatial learning.This research was conducted while the senior author served as Principal Investigator for National Institute on Aging Grant No. 1 ROI AG05169, Aging and Spatial Cognition, sponsored by the National Institutes of Health, Bethesda, MD, USA 相似文献

Summary The role of intention in guiding the behavior of goal-directed systems is a problem that continues to challenge behavioral science. While it is generally agreed that intentional systems must be consistent with the laws of physics, there are many obvious differences between inanimate, physical systems and sentient, intentional systems. This suggests that there must be constraints over and above those of physics that govern goal-directed behavior. In this paper it is suggested that generic properties of self-organizing mechanisms may play a central role in the origin and evolution of intentional constraints. The properties of self-organizing systems are first introduced in the context of simple physical systems and then extended to a complex (biological) system. Whereas behavior of an inanimate physical system is lawfully determined by force fields, behavior of an animate biological system is lawfully specified by information fields. Biological systems are distinguished from simple physical systems in terms of their ubiquitous use of information fields as special (biological and psychological, social, etc.) boundary conditions on classical laws. Unlike classical constraints (boundary conditions), informational constraints can vary with time and state of the system. Because of the nonstationarity of the boundary conditions, the dynamic of the system can follow a complex trajectory that is organized by a set of spatially and temporally distributed equilibrium points or regions. It is suggested that this equilibrium set and the laws that govern its transformation define a minimal requirement for an intentional system. One of the benefits of such an approach is that it suggests a realist account for the origin of semantic predicates, thereby providing a basis for the development of a theory of symbolic dynamics. Therefore, the principles of self-organization provide a comprehensive basis for investigating intentional systems by suggesting how it is that intentions arise, and by providing a lawful basis for intentional behavior that reveals how organisms become and remain lawfully informed in the pursuit of their goals. 相似文献

Hispanics in Ivy: Assessing identity and perceived threat 总被引:1,自引:0,他引:1
Membership in social groups is an important aspect of the self-concept, as a number of theorists such as Tajfel (1981) have recognized, and ethnic identity is a major exemplar of such groupings. In the present research, we focus on the particular case of Hispanic identity and the degree to which that identity may be threatened for first-year Hispanic students who enter a predominantly Anglo university. Forty-five Hispanic students (17 female, 28 male) at two Ivy League universities were interviewed early in their first year to assess Hispanic identity, collective self-esteem (Luhtanen & Crocker, 1988), and perceived threats to Hispanic identity. In addition, we considered the degree to which strength of cultural background relates to self-esteem and to perceptions of threat. The majority of students claimed Hispanic as an important identity. Strength of cultural background generally acted as a buffer to perceived threat, particularly for men. Cultural background was also related to collective self-esteem for men but not for women, even though Hispanic identity was more important for women than men. The results attest to the importance of both gender and ethnicity to self-definition and self-esteem, as well as to the complexity of the relationships among these variables.We thank Tracey Revenson as well as the members of the Identity Research Seminar at the CUNY Graduate Center for their comments on an earlier version of this paper. 相似文献

Are women in a female-dominated profession more successfully able to combine work and family obligations than women in a male-dominated profession? To explore this question, a comparison was made between the family status and careers of 747 women librarians (a female-dominated profession) and those of 449 women MBAs (a male-dominated profession). It was expected that the librarians would marry earlier and have more children. This general prediction was not supported. Over half of both groups of women were married, and after controlling for age, there were no differences in number of children. However, many women without children in both groups reported that they would like to be mothers. This disparity between wanting children and not having them was more common for women MBAs than women MLSs. MBAs and librarians were about equally likely to have had job interruptions, but librarians were more likely to have worked part-time. Reasons for an interruption to full-time work were as likely to be for problems finding (full-time) work as for family responsibilities. Librarians' salaries were much lower, but job interruptions and part-time work had a more negative effect on the salaries of women in business. In sum, the data suggest that many of the women surveyed have not combined motherhood with a professional career and that it is probably somewhat more difficult to combine a family with a career in business than with a career in library science. 相似文献

This study tested the applicability of Tajfel and Turner's (1986) Social Identity Theory (SIT) to cooperative behavior in a mixed-gender setting. SIT suggests that as a “socially subordinate” group in a male-dominated society, women, when their gender is in the numerical minority, will engage in social competition in an attempt to enhance social identity. However, gender-based socialization may encourage men toward competition and women toward cooperation, regardless of group gender composition. In this study, male and female subjects were assigned to a six-person mixed-gender group in which their gender was either in the numerical minority or majority, and performed an interactive task under either cooperative or competitive feedback. An interaction of sex and feedback showed males in the cooperative feedback condition responded more competitively than did males in the competitive feedback condition, while females were equally cooperative in both feedback conditions. Feedback also interacted with the numerical ingroup/outgroup gender balance. While competitive feedback elicited little variation in subjects' responses across the ingroup/outgroup balance variable, the cooperative condition elicited greater competition from subjects in the numerical minority and greater cooperation from those in the numerical majority. Results were interpreted as partial support for SIT, while stressing the need for further investigation into gender as a unique influence on intergroup behavior. 相似文献

The relationship between program performance and outcome for patients in maximum security token economy programs has not been previously studied. We examined variables related to success in a token economy program and to postrelease failure for 92 men in a maximum security psychiatric hospital. Point earnings later in the program were best predicted by earlier point earnings. Variables that best predicted postrelease failure, defined in various ways, were similar to those found in other studies; youthfulness, having spent more time in institutions, a diagnosis of personality disorder or retardation rather than psychosis, not having been found not guilty by reason of insanity or unfit to stand trial, and having been referred from another psychiatric hospital. That program variables were generally unrelated to later outcome suggests that treatment programs for patients in maximum security settings must emphasize skills that are relevant to postrelease success. 相似文献

Health care reform has put increasing pressure on faculty of medical schools to become self-supporting. Opportunities for clinical revenue will decrease, but psychologists who are able to generate research funding will become increasingly competitive, albeit as mercenaries, i.e., capable of paying their own way plus generating a profit to support departmental operations and educational programs. Changes in the health care system signal an end to psychiatry's paternalistic relationship to psychology and present opportunities for psychology proactively to influence its future role in health care. Research, political action, and revised scientific mission, models, and roles represent important strategies in the redefining of psychology as a basic science and major profession in health care. 相似文献
