Pigeons were exposed to a two-key concurrent chains schedule in which identical frequencies and distributions of food presentations generated different response rates in the terminal links. An inverse relation between local rate of response in the terminal links and relative frequency of response in the initial links was observed. The high response rate was produced in one terminal link by a second-order schedule in which responding produced brief blackouts of the response key. Responding under the same schedule in the other terminal link did not produce blackouts. Under initial training and after spatial reversal of the terminal-link schedules, two of three pigeons had lower relative frequencies of response in the initial member of the chain with the higher terminal link response rate. The third pigeon showed no change in preference at reversal. 相似文献

Culture wars: American moral divisions across the adult lifespan 总被引:1,自引:0,他引:1

Sociologists have argued that the public moral debate in contemporary America is characterized by a “culture war,” pitting
“orthodox” and “progressivist” groups against one another (Hunter, 1991). This study addressed whether the culture war is
evident in the moral thinking of ordinary Americans, and whether age-related patterns exist. Sixty fundamentalist Baptists
(orthodox) and 60 mainline Baptists (progressivist) evaluated and reasoned about moral issues such as divorce and abortion.
Each group was divided evenly into three age groups copsisting of young, midlife, and older adults. Moral reasoning was analyzed
in terms of Shweder's (1990) ethics of autonomy, community, and divinity. Within all three age groups, progressivists used
the ethic of, autonomy more than orthodox participants. Orthodox participants used the ethic of divinity more than progressivists.
Orthodox and progressivist groups did not differ much in their use of the ethic, of community. Very few age group differences
were found within the orthodox and progressivist groups. It is concluded that morality is conceived of in markedly different
wasy by orthodox and progressivist groups, and that these conceptions are consistent across age groups. 相似文献

Age-related changes in rate of visual information processing 总被引:1,自引:0,他引:1

Each of four groups of 12 subjects performed four psychophysical tasks. The age ranges of the four groups were 19-31, 45-57, 58-70, and 71-83 years, respectively. All four tasks required some form of visual information processing: Two were backward-masking tasks; two were temporal-integration tasks. In all four tasks increasing temporal functions over age were obtained, suggesting slower processing rates as age increased. The results support an active processing model of visual perception that interprets duration of visible persistence and duration of interval in which backward masking is effective as indices of the time course of early stages in the processing of stimulus features. The evidences also suggests that backward masking and visible persistence may be mediated by distinct mechanisms that are affected differently by aging processes. A model that conceptualizes the visual system as a multichannel processor is proposed as an explanation for some of the findings. 相似文献

Temporal aspects of early visual information processing were studied developmentally in good and in poor reading male subjects ranging in age from 7 to 13 years. Forced-choice temporal integration and backward masking tasks, respectively, were utilized to assess duration of visual persistence and of relative rate of visual information processing. The results did not reveal differences in either visual persistence or processing rate in relation to reading ability at any age level studied. However, processing rate was found to increase markedly with chronological age in both the good and the poor readers while visual persistence did not vary significantly. The findings were discussed in relation to earlier work and in relation to current theoretical formulations of visual information processing. 相似文献

G. Stanley Hall's two-volume work on adolescence is assessed from the perspective of modern psychology, 100 years after he published it. A surprising number of similarities exist between Hall's views of adolescence and our own, and several of those similarities are discussed here. Some of the most striking differences between Hall's views and the views of today's psychologists are also discussed, specifically, Hall's grounding of his beliefs about adolescent development in a Lamarckian evolutionary psychology that assumed the inheritance of acquired characteristics and memories; his views of sexuality, especially masturbation; and his claim that religious conversion is normative in adolescence. The cultural and historical context of Hall's views is then discussed, with an emphasis on how an awareness of the context of Hall's views can enhance our awareness of the context of our own views today. 相似文献

This article is an overview of the special issue "G. Stanley Hall's Adolescence: A Centennial Reappraisal." First, a brief biography of Hall is presented. Then each of the six articles in the special issue is summarized. Three of the articles are by historians and three are by psychologists, but all six articles integrate history and psychology. 相似文献

Usual scoring systems for figure drawing techniques are based on structural and content aspects of the drawing, and ignore the affectively toned associations that occur when an observer first sees a drawing. A system for measuring two components of judgment, (a) emission of affective associations (b) evaluation of affective associations, has been developed. This method was applied with some success in studying individuals who had represented in their drawings an image that corresponded to their actual physical appearance. The research so far suggests that the evaluation component of judgment may contribute more to discrimination than the emission component. 相似文献

Three pigeons were exposed to a two-component multiple schedule in which a variable-interval 3-min schedule was always in effect in one component. The schedule in the other component was either variable-interval 3-min or extinction in alternate blocks of sessions. When the schedule was changed from multiple variable-interval 3-min variable-interval 3-min to multiple variable-interval 3-min extinction in the second and fourth phases of the experiment, overall response rates in the unchanged variable-interval 3-min component increased in two pigeons. Response rate declined when the schedule was changed to multiple variable-interval 3-min variable-interval 3-min again. Correlated with increases in overall response rate in the unchanged component were increases in local response rates at the beginning of the unchanged component and immediately after food presentation. Local rates 40 sec after food presentation did not increase greatly in the presence of the multiple variable-interval 3-min extinction schedule. An interresponse time analysis of three local rate samples showed small increases in the relative frequency of short-duration interresponse times at the beginning of the unchanged component and immediately after food presentation. Neither the postreinforcement pause nor the latency to the first response in the unchanged component changed systematically. 相似文献

This article proposes that psychological research published in APA journals focuses too narrowly on Americans, who comprise less than 5% of the world's population. The result is an understanding of psychology that is incomplete and does not adequately represent humanity. First, an analysis of articles published in six premier APA journals is presented, showing that the contributors, samples, and editorial leadership of the journals are predominantly American. Then, a demographic profile of the human population is presented to show that the majority of the world's population lives in conditions vastly different from the conditions of Americans, underlining doubts of how well American psychological research can be said to represent humanity. The reasons for the narrowness of American psychological research are examined, with a focus on a philosophy of science that emphasizes fundamental processes and ignores or strips away cultural context. Finally, several suggestions for broadening the scope of American psychology are offered. 相似文献
