It has become increasingly clear that some patients with apparently normal memory may subsequently show accelerated long-term forgetting (ALF), with dramatic loss when retested. We describe a constrained prose recall task that attempts to lay the foundations for a test suitable for detecting ALF sensitively and economically. Instead of the usual narrative structure of prose recall tests, it employs a matrix structure involving four episodes, each describing a minor crime, with each crime involving the binding into a coherent episode of a specified range of features, involving the victim, the crime, the criminal and the location, allowing a total of 80 different probed recall questions to be generated. These are used to create four equivalent 20-item tests, three of which are used in the study. After a single verbal presentation, young and elderly participants were tested on three occasions, immediately, and by telephone after a delay of 6 weeks, and at one of a varied range of intermediate points. The groups were approximately matched on immediate test; both showed systematic forgetting which was particularly marked in the elderly. We suggest that constrained prose recall has considerable potential for the study of long-term forgetting. 相似文献

The article reports an experiment testing whether the Hebb repetition effect—the gradual improvement of immediate serial recall when the same list is repeated several times—depends on overt recall of the repeated lists. Previous reports which suggest that recall is critical confound the recall manipulation with retention interval. The present experiment orthogonally varies retention interval (0 or 9 s) and whether the list is to be recalled after the retention interval. Hebb repetition learning is assessed in a final test phase. A repetition effect was obtained in all four experimental conditions; it was larger for recalled than non-recalled lists, whereas retention interval had no effect. The results show that encoding is sufficient to generate cumulative long-term learning, which is strengthened by recall. Rehearsal, if it takes place in the retention interval at all, does not have the same effect on long-term learning as overt recall. 相似文献

We compared the accuracy of the Brief Cognitive Assessment Tool—Short Form (BCAT-SF) and AD8 in identifying mild cognitive impairment (MCI) and dementia among long-term care residents. Psychometric analyses of 357 long-term care residents (n = 228, nursing home; n = 129, assisted living) in Maryland referred for neuropsychological evaluation evidenced robust internal consistency reliability and construct validity for the BCAT-SF. Furthermore, hierarchical logistic regression and receiver operating characteristic curve analyses demonstrated superior predictive validity for the BCAT-SF in identifying MCI and dementia relative to the AD8. In contrast, previously reported psychometric properties or cut scores for the AD8 could not be cross-validated in this long-term care sample. Based on these findings, the BCAT-SF appears to be a more reliable and valid screening instrument than the AD8 for rapidly identifying MCI and dementia in long-term care residents. 相似文献

SUMMARY Given the increase in rates of intermarriages, it is vital that we understand the issues and benefits of interracial relationships and the ways in which therapists might assist interracial couples. Our focus in this article is on interracial relationships in Hawaii. Because of its history of promoting interracial ties and its plural character, Hawaii is, in many ways, a unique setting for interracial relationships. At the same time, there are relational issues, benefits, and needs faced by both mainstream U.S. interracial couples and interracial couples in Hawaii. There are a variety of therapeutic interventions that could be used to help interracial couples. This chapter examines the factors in Hawaii's past and present that contribute to its particular history of interracial relationships, the common challenges that face interracial couples, personal and relational benefits of interracial relationships, and the therapeutic interventions from which interracial couples may benefit. 相似文献

Intelligence is considered as a stable trait over time; psychologists make predictions about the future performance of the child from the interpretation of the WISC-IV scores. However, stability at interindividual level does not necessarily imply stability at intra-individual level. By a test-retest procedure, the stability of categories that classify the performances, and the stability of the personal strengths and personal weaknesses are evaluated on a sample of 277 children aged from seven to 12 years. Categorical stability reveals that the classification into seven categories proposed by the designers of the WISC-IV does not allow reliable predictions. The stability of personal strengths and personal weaknesses is unsatisfactory for the different index scores. 相似文献

By a Test–Retest procedure, this study explores the long-term stability of the French WISC-IV index scores. The average Test–Retest interval was 2.33 years. The sample consisted of 96 non-clinical children aged between 8 and 12 years. Mean difference between the two testings was not statistically significant for VCI, PRI, WMI, GAI and FSIQ. Test–Retest reliability correlations between the two assessments are high for VCI, GAI and FSIQ (ranging from .81 to .82). An analysis of the performance differences between two assessments indicates intra-individual stability for WMI and GAI. In sum, only GAI demonstrates reliable long-term stability at an inter-and intra-individual level. 相似文献

This study investigated marital satisfaction among graduate students. Using the Marital Satisfaction Inventory-R (MSI-R), 65 graduate students were surveyed. The results revealed multiple common areas of marital concern based on degree program of the student. These findings offer implications for psycho-educational and responsive interventions for clinicians working with this population. 相似文献

Recalling one memory often leads to the recollection of other memories that share overlapping features. This phenomenon, spreading activation, was originally documented in studies conducted with verbal adults, and more recently, it has been demonstrated with preverbal infants. Here, we examine the effect of spreading activation on long-term retention by 2-year-olds. Participants were tested in the Visual Recognition Memory (VRM) paradigm and the deferred imitation paradigm. Typically, infants of this age exhibit retention in the VRM paradigm for 24 h, while they exhibit retention in the deferred imitation paradigm for at least 8 weeks. In the present experiment, we paired these tasks together during original encoding and tested infants after an 8-week delay. Two-year-olds exhibited retention in both tasks. That is, when these two tasks initially occurred together – one task that is extremely memorable and one that is not – retrieving the memory of the more memorable task cued retrieval of the less memorable task, extending its longevity. 相似文献
