Free-recall and multiple-choice measures of memory for landmarks, sequential order, turns, and route configurations were obtained from younger and older adults after they viewed slides of 2 overlapping routes. Instructions focused attention on either the contents of the slides or on the course of the path; a control condition provided no orientational instructions. Half the subjects viewed maplike diagrams of the joint spatial configuration. Age interacted with instruction only for multiple-choice tests of landmark memory. Age interacted with diagram for each of the other 3 route memory components, although the generality of this interaction across instruction condition depended on whether free-recall or multiple-choice tests were used. The results suggest that route memory may involve both scene and layout representation, which may be differentially sensitive to age and presentational variables. 相似文献

Short-term memory for actions was investigated for young adult and elderly adult subjects with the Brown-Peterson procedure at retention intervals of 0 and 15 s. The short-term memory trials were followed by the long-term recall of the prior to-be-remembered actions. The 15-s retention interval was filled either with no activity or with 1 of 3 different interfering activities. Verbal interference had little effect on short-term memory at either age level. Actions performed in the interval either by the subjects or by the experimenter produced significantly lower recall scores at each age level, with the decrement being more pronounced for the elderly than for the young subjects. The long-term memory results indicated that successful short-term recall enhanced later long-term recall, regardless of age level. 相似文献

The dimensions by which adults of differing ages experience emotion were studied by self-administering questionnaires administered to older adults (n = 828) recruited from Elderhostel programs, middle-aged (ages 30-59) children of Elderhostel attenders (n = 231), and young adult (ages 18-29) subjects recruited from college classes or through Elderhostel participants (n = 207). Elders were higher in emotional control, mood stability, and emotional maturity through moderation and leveling of positive affect and lower in surgency, psychophysiological responsiveness, and sensation seeking. These findings are consistent with the hypothesized increase in self-regulatory capacity with age. These cross-sectional differences cannot, however, be distinguished from cohort-related explanations; they require considerable replication across different types of subjects and further characterization of the dimensions in terms of their functions for self-regulation. 相似文献

The present research examined whether line-ups based on target (‘suspect’) face similarity are biased or suggestive. Four experiments are described in which subjects constructed photographic line-ups by selecting foils similar in appearance to a target. Later, another group of subjects who had not seen the faces before (mock witnesses) were asked to pick out the targets from the line-ups. All four experiments showed that mock witnesses selected the target significantly more often than expected by chance, thereby demonstrating suggestiveness. Three alternative line-up construction methods were also evaluated. In these methods, foil selection was based not only on target similarity but also on similarity with one or more of the other line-up faces. Results showed that alternative line-up targets were not selected significantly more often than chance, suggesting that bias was reduced. An overall analysis showed that the alternative line-ups were significantly less suggestive than target-based line-ups. The results indicate that foil selection procedures that incorporate foil-to-foil similarity produce fairer line-ups than those exclusively based on target similarity. 相似文献

Mental health practitioners are faced with a profound challenge surrounding the prevalence of adult mental disorders, the need for inpatient treatment programs, and the costs of such programs. This paper describes the development of an adult inpatient psychiatric program based on Rational-Emotive Therapy. Specific elements of this program are described briefly, and preliminary outcome data presented on 372 patients. Concerns and future directions are also discussed. Development of adult inpatient psychiatric programs based on Rational-Emotive Therapy would appear to be one method of providing effective and cost-efficient treatment within the current cost-containment atmosphere of psychiatric treatment.Dr. Nottingham is an Associate Fellow and Approved Supervisor of the Institute for Rational-Emotive Therapy. He is in independent practice with Germantown Psychological Associates, P.C. and is Director of Psychology at Parkwood Hospital, Olive Branch, MS. Dr. Neimeyer is an Associate Professor and Director of Clinical Training in the Department of Psychology of Memphis State University. He has written extensively in the areas of cognitive and constructivist psychotherapy, and is co-editor of the International Journal of Personal Construct Psychology.The authors would like to thank Kat Bagley, Joe Grillo, Ivey Bright, Brooke Bensen, Cathy Michas, Brad Barris, Lori Passmore, David Wilkins, and Dee Conrad for their help with data collection. Additionally, without the assistance and support of the Parkwood Hospital administration and staff, neither this treatment program nor this paper could have been developed.Portions of this paper based on earlier data analyses were presented at the Mississippi Psychological Association Convention, September, 1990. This research was conducted at Parkwood Hospital. 相似文献

Mental health professionals who lack medical training may also lack knowledge and understanding of the potential utility of medications in the treatment of emotional disturbance. They may also lack information regarding the effects and side-effects of medications which their clients may already be taking, or be uncertain when the nature of their client's situation suggests a psychiatric assessment regarding drug therapy. This paper offers an educational review in one such area: the pharmacological treatment of depression. It includes a brief review of theories regarding the aetiology of affective disorder, examines the methodes, mechanisms and efficacy of anti-depressants, and draws conclusions regarding the appropriate use of pharmacological treatment. 相似文献

Premissary relevance is a property of arguments understood as speech act complexes. It is explicable in terms of the idea of a premise's lending support to a conclusion. Premissary relevance is a function of premises belonging to a set which authoritatively warrants an inference to a conclusion. An authoritative inference warrant will have associated with it a conditional proposition which is true— that is to say, which can be justified. The study of the Aristotelian doctrine of topoi or argument schemes may contribute to the task of identifying authoritative warrants. 相似文献
