ABSTRACT Research demonstrates a positive effect of aerobic exercise on cognitive functioning in older adults. Unfortunately, aerobic exercise is often contraindicated for older adults due to cardiovascular and functional limitations. Low-intensity strengthening exercise may offer a practical alternative, but the neuropsychological benefits and potential neurophysiological mechanisms are less well understood. The current study evaluated the effects of a 10-week strengthening exercise intervention on cognitive functioning and EEG in a sample of 13 older adults with early dementia, and 9 normative controls. Results revealed beneficial effects of strengthening exercise on verbal memory coupled with frontal beta and delta power asymmetries and N200 amplitude asymmetry. Results point to increased cognitive efficiency following 10 weeks of strengthening exercise. The findings suggest it is feasible to conduct a strengthening intervention with early dementia patients, and to gather neuropsychological and neurophysiological data to evaluate outcomes. Strengthening exercise may serve as a useful alternative to aerobic exercise. 相似文献

This paper describes the development and validation of a physical performance test battery to select high pressure cleaning workers at Tennessee Eastman Company. The research uses a concurrent, criterion-related validation strategy to demonstrate the relationship between test performance and job performance. The study proceeded through four stages, with data collected in one stage used in subsequent stages. The two types of predictor measures included ability tests and work sample simulations. For some analyses, the work sample simulations were also used as criteria. Four samples of incumbents (N=63) were tested on all experimental measures. Using criterion groups of successful incumbents and unsuccessful former incumbents (N=33), all of the work simulation tests and the ability-referenced tests were significant predictors of successful versus unsuccessful job status. In addition, the ability tests predicted performance on the work sample simulations, particularly for those requiring strength and endurance. A battery of three ability tests resulted in R=.68 for job status and in R=.43, .73, .80, and .84, respectively, for each of the work sample simulations. Two of the three ability tests in the final test battery are likely to result in adverse impact against females. However, data collected on female maintenance technicians indicated women, as a group, would not be screened out categorically as a result of implementing the physical ability test battery. 相似文献

This research addressed the question of whether stage-related patterns of early cognitive development, reported for normally developing children in the first two and a half years of life, may also characterize the development of at-risk and handicapped children when mental age rather than chronological age is used to organize the data. Performance on a psychometric infant test and two neo-Piagetian-based stage measures was assessed for 95 at-risk and handicapped children. Mental age predicted cognitive level of performance for levels 1 to 3, representing the first year and a half of development, but did not predict the highest level, symbolic functioning. In addition, transition points between levels were observed at mental ages similar to the chronological ages when these transitions have been reported for normally developing infants, for all but the last level. The significance of the correspondence between the psychometric measure and the stage measures is discussed and several alternatives for the breakdown at the highest level are considered. 相似文献

The conservatism construct has previously proved predictive of social and psychological dimensions having both practical and theoretical relavance. Its potential, however, has typically been limited by measurement imprecision due principally to the use of lengthy and potentially ambiguous verbal statements subject to either intentional or unintentional response bias. Wilson and Patterson's recently developed Conservatism Scale (C-scale) is intended to obviate the more critical sources of bias inherent in the traditional conservatism measures. In an extended test of the C-scale's validity, the present study finds 12 categories of "known groups" scoring as theoretically expected, and further shows C-scale scores consistently and significantly correlated with eight theoretically related dimensions. 相似文献

The paper proposes a cognitive structure consistent with principles of encoding and a rule for its utilization in verbal recall. The encoding and utilization rules lead to phenomena similar to known serial position effects. A detailed analysis of overt rehearsal data and other experimental results are presented in support of the claim that encoding and search mechanisms characterized by these rules could be important factors in serial position effects of verbal recall. Similar rules might be helpful in dealing with other tasks which seem to mirror the utilization of a cognitive structure. 相似文献
