In a prior study of 54 relatives of patients with schizophrenia and 72 control participants, 3 neuropsychological functions met the criteria for risk indicators of the schizophrenia genotype: executive functioning, memory, and auditory attention. In an assessment of the stability of these findings, the sample was reexamined 4 years after the initial assessment. Three test scores were found to differ between groups (Immediate Verbal Memory, Delayed Verbal Memory, and Dichotic Listening Digits Detected) or to show a significant Group x Gender interaction (immediate and delayed verbal and visual memories). None of the test scores showed Group x Time interactions, suggesting that the discriminating power of the tests was stable over time. Evidence for deficits in working memory and rule learning on the object alternation test was also found. These results support the idea that neuropsychological dysfunction among relatives of patients with schizophrenia is a stable trait caused by the familial predisposition to schizophrenia.  相似文献

Test scores of 119 students, attending either a public four-year college or a technical school, were related to their proportionality and detail drawing scores on the Memory for Designs Test. In regression models, the ETS Maze Tracing, Eliot-Price Mental Rotations, and Bender-Gestalt tests were consistent predictors of proportionality scores, with the latter two tests uniquely related to these. The ETS Shapes Memory Test and the Form Board Test were the strongest predictors for detail accuracy scores. The Shapes test predicted proportionality when the CTY Visual Memory Test BB was excluded. The models then provided support for the hypothesis that drawing designs from memory, a critical skill in drawing, regardless of whether one focuses on accuracy for proportionality scores or for detail scores, is jointly related to the measures of recognition, production, and traditional spatial ability measures. This study identified multifaceted skills in drawing from memory.  相似文献

The present study examined parallel-form reliability of the Wechsler Memory Scale (WMS) in a population where such forms are particularly useful, that is, among patients who are suspected of having some type of dementing illness. Comparative analyses were made for total raw scores. Memory Quotient (MQ) scores, and individual subtest scores. Thirty geriatric patients originally referred for neuropsychological testing because of suspected dementia were given both Forms 1 and 2 of the WMS. The results yielded high overall reliability coefficients for MQ and total raw scores. Individual subtest scores also yielded rather high coefficients, and only one subtest (Associate Learning) had a significant mean difference. Apparently, the two forms have sufficient parallel-form reliability to be considered clinically interchangeable. Thus, the WMS may be a useful tool for repeat evaluations of memory functioning in a demented population.  相似文献

In this pilot study, implicit memory was examined in participants selected according to their scores on the Wechsler Memory Scale-Revised. Implicit memory was explored using a word-stem completion test after 24 participants had processed texts to be remembered. Variations in priming were observed among 12 Normal and 12 Good memorizers (Verbal Memory scores >110) following presentation of target words in the context of a coherent text. One intriguing result emerged: the magnitude of the priming effect varied by group, greater among Good memorizers than Normal memorizers.  相似文献

Different forms of memory defects were studied in 16 patients with organic dementia. The test performance was related to the regional cerebral blood flow (rCBF) in the left (dominant) hemisphere. Verbal memory (Paired Associates) correlated to the blood flow in temporal and parietal regions. Spatial recognition (Memory for Objects, Memory for Geometrical Design) correlated to the temporal and lower frontal regions. One spatial memory test (Visual Retention test) correlated to the temporal region only. Another spatial memory test (Memory for Design) did not show correlations to any regions of the dominant hemisphere. Finally it was found that the hemisphere mean flow values did not correlate to performance. This emphasizes the main finding—the regional correlations. It is concluded that memory performance involves various extratemporal regions depending upon the specific quality of the memory task to be performed.  相似文献

Words that are read aloud are more memorable than words that are read silently. The boundaries of this production effect (MacLeod, Gopie, Hourihan, Neary, & Ozubko, Journal of Experimental Psychology: Learning, Memory, and Cognition, 36, 671-685, 2010) have been found to extend beyond speech. MacLeod and colleagues demonstrated that mouthing also facilitates memory, leading them to speculate that any distinct, item-specific response should result in a production effect. In Experiment 1, we found support for this conjecture: Relative to silent reading, three unique productions-spelling, writing, and typing-all boosted explicit memory. In Experiment 2, we tested the sensitivity of the production effect. Although mouthing, writing, and whispering all improved explicit memory when compared to silent reading, these other production modalities were not as beneficial as speech. We argue that the enhanced distinctiveness of speech relative to other productions-and of other productions relative to silent reading-underlies this pattern of results.  相似文献

The goal of the present study was to investigate relationships between personal beliefs about memory, metacognitive beliefs, and actual memory performance. One hundred thirty-seven participants' (aged 20 to 60 years) metacognitive beliefs were measured using the Metacognition Questionnaire (MCQ-30), memory beliefs were measured using the Personal Beliefs about Memory Instrument (PBMI), and an episodic memory task was used to measure actual memory performance, memory predictions, and postdictions. Younger adults had lower scores on the positive beliefs subfactor of the MCQ-30, higher scores on retrospective change and control subfactors of the PBMI, and outperformed middle-aged adults on recall and recall postdiction. Path analysis showed that individuals' beliefs about memory mediate the relationship between metacognitive beliefs and actual memory performance. Specifically, low lack of confidence (or less worry) in one's own memory and attentional capabilities was related to higher memory performance and positive personal beliefs regarding specific memory ability mediated relationship.  相似文献

This study investigated the relationships between cognitive-perceptual personality dimensions (transliminality and delusional ideation) and self-report measures of memory error (Oblivion Scale and the Prospective and Retrospective Memory Questionnaire). 100 full- and part-time psychology undergraduate students completed the measures (18 men and 82 women; M = 19.3 yr., SD = 4.4). A positive correlation was found between transliminality and reported memory aberrations (Oblivion Scale scores) and also between transliminality and Prospective and Retrospective Memory Questionnaire scores. Correlations were positive between Peters, et al. Delusions Inventory and the self-report memory measures. Transliminality and Peters, et al. Delusions Inventory scores predicted the number of memory aberrations or slips reported on the Oblivion Scale and Prospective and Retrospective Memory Questionnaire. To explore whether transliminality explained additional variance to that accounted for by the Peters, et al. Delusions Inventory, forward regression was applied and showed aspects of transliminality not accounted for by Peters, et al. Delusions Inventory did not explain additional variance within the self-report memory measures.  相似文献

Patient memory for the contents of treatment is staggeringly poor, and poor memory for treatment is associated with worse treatment outcome. Accordingly, the Memory Support Intervention was developed to improve patient memory for treatment as an adjunct to treatment as usual. As plans to disseminate the Memory Support Intervention are developed, it is important to have efficient, accurate methods of measuring fidelity to the intervention. However, the existing method of assessing fidelity to the Memory Support Intervention, the Memory Support Rating Scale (MSRS), is burdensome and requires trained independent-raters to spend multiple hours reviewing session recordings, which is not feasible in many routine mental health care settings. Hence, a provider-rated measure of fidelity to the MSI has been developed. The goal of this study is to examine the reliability and validity of scores on this measure—the Memory Support Treatment Provider Checklist. A sample of Memory Support Treatment Provider Checklists (N = 319) were completed by providers (N = 8) treating adults with depression (N = 84). Three metrics of the Memory Support Treatment Provider Checklist were evaluated: (a) the internal consistency and structural validity using confirmatory factor analysis based on prior research on the MSRS and the Memory Support Intervention, (b) construct validity, and (c) predictive validity. Results indicate that the Memory Support Treatment Provider Checklist yields reliable and valid scores of fidelity to the Memory Support Intervention. Overall, this checklist offers a viable, brief method of evaluating fidelity to the Memory Support Intervention.  相似文献
