The present work aims to establish a greater understanding of the cognitive mechanisms involved in avoiding distraction from speech and nonspeech sounds. Although mixed results have been presented by research investigating the hypothesis that individuals with superior working memory abilities are better able to avoid acoustic distraction, we found that working memory correlated with some aspects of performance during distraction when carefully examined. This is consistent with the view that working memory involves resisting interference. In a large sample, we examined two different tasks accompanied by acoustic distraction—serial recall and rapid colour naming—as well as two different measures of working memory (operation span and running span). We show that the previous inability to find relations between working memory and avoidance of distraction may stem from the use of inadequate correlational techniques. Additionally, the level of difficulty of the serial recall task may be an important factor. The results illustrate that commonly used statistical techniques can be misleading and furthermore that the ability to avoid distraction from irrelevant items may not be a unitary construct. 相似文献

This article presents a counseling strategy selection model grounded in technical eclecticism (A. A. Lazarus & L. E. Beutler, 1993) and based on thorough assessment of the client's problems. Assessment should consider client mental health, counseling goals, problem complexity, and capacity and desire for insight. Distinguishing between simple and complex problems can aid assessment and provide direction for counseling modality selection (L. E. Beutler & J. F. Clarkin, 1990). Behavioral interventions are more appropriate for less complex problems or when capacity or desire for insight is low. Insight‐based interventions are more appropriate for more complex problems or when capacity or desire for insight is high. 相似文献

Students with emotional disturbance (ED) experience the worst outcomes of any group of pupils in the public schools. We suggest that at least part of the reason is that the services they receive while in school are inadequate to meet their needs. Although applied research has resulted in a number of effective practices, they are not used in the majority of America's schools. Barriers to the implementation of such practices are described, and recommendations for improving programs and outcomes for these students are offered. 相似文献

Service (1998) carried out a study of the word length effect with Finnish pseudowords in which short and long pseudowords were identical except for the inclusion of certain phonemes differing only in pronunciation length, a manipulation that is impossible in English. She obtained an effect of phonemic complexity but little or no word duration effect per se - a discrepancy from the expectations generated by the well-known working memory model of Baddeley (1986). In the present study using English words, we controlled for phonemic complexity differences by using the same words for the short- and long-word sets, but with instructions inducing shorter or longer pronunciation of the words. We obtained substantial word duration effects. Concerns raised by Service are addressed, and we conclude that both duration and complexity are likely to contribute to the word length effect in serial recall. 相似文献

Many results concerning the equivalence between a syntactic form of formulas and a model theoretic conditions are proven directly without using any form of a continuum hypothesis. In particular, it is demonstrated that any reduced product sentence is equivalent to a Horn sentence. Moreover, in any first order language without equality one now has that a reduced product sentence is equivalent to a Horn sentence and any sentence is equivalent to a Boolean combination of Horn sentences. 相似文献
