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

Previous research has shown that, when hearers listen to artificially speeded speech, their performance improves over the course of 10–15 sentences, as if their perceptual system was “adapting” to these fast rates of speech. In this paper, we further investigate the mechanisms that are responsible for such effects. In Experiment 1, we report that, for bilingual speakers of Catalan and Spanish, exposure to compressed sentences in either language improves performance on sentences in the other language. Experiment 2 reports that Catalan/Spanish transfer of performance occurs even in monolingual speakers of Spanish who do not understand Catalan. In Experiment 3, we study another pair of languages— namely, English and French—and report no transfer of adaptation between these two languages for English—French bilinguals. Experiment 4, with monolingual English speakers, assesses transfer of adaptation from French, Dutch, and English toward English. Here we find that there is no adaptation from French and intermediate adaptation from Dutch. We discuss the locus of the adaptation to compressed speech and relate our findings to other cross-linguistic studies in speech perception. 相似文献

Social support systems can have either a beneficial or adverse effect when a family faces stress. Hence, support perceived by family members is an important construct. We studied the psychometric properties of the Family Support Scale (FSS) with a sample of 244 low-income families of children in a Head Start program, and we conducted an exploratory factor analysis with the scale. We obtained a 5-factor solution for the FSS when assessing the family support of low-income families. The internal consistency and test-retest reliability were moderately high for the 5 proposed subscales. The factor structure obtained may prove more valid for Head Start families than structures from previous studies, although there is still a need for further psychometric study of the FSS. 相似文献

The current study assumes that workers actively influence the characteristics of their work environment. Not only will one's work environment (job characteristics) affect personal characteristics, such as feelings of depression; depression in turn is expected to affect the characteristics of one's work environment as well. Using a sample of 593 young Dutch workers, a longitudinal model relating feelings of depression and job characteristics to each other was tested using structural equation modeling. The results largely supported our expectations. Depressive workers were less likely to experience a job transition than non-depressive workers. If depressive workers did experience a job transition, work outcomes were less positive than for nondepressive workers. Thus, it appears that the relation between job characteristics and depression can be construed as a reciprocal relation. Implications and limitations of the study are discussed. 相似文献

Avian brood parasites depend on other species, the hosts, to raise their offspring. During the breeding season, parasitic
cowbirds (Molothrus sp.) search for potential host nests to which they return for laying a few days after first locating them. Parasitic cowbirds
have a larger hippocampus/telencephalon volume than non-parasitic species; this volume is larger in the sex involved in nest
searching (females) and it is also larger in the breeding than in the non-breeding season. In nature, female shiny cowbirds Molothrus bonariensis search for nests without the male’s assistance. Here we test whether, in association with these neuroanatomical and behavioural
differences, shiny cowbirds display sexual differences in a memory task in the laboratory. We used a task consisting of finding
food whose location was indicated either by the appearance or the location of a covering disk. Females learnt to retrieve
food faster than males when food was associated with appearance cues, but we found no sexual differences when food was associated
with a specific location. Our results are consistent with the view that parasitism and its neuroanatomical correlates affect
performance in memory tasks, but the effects we found were not in the expected direction, emphasising that the nature of avian
hippocampal function and its sexual differences are not yet understood.

Job satisfaction data on managerial personnel were used to illustrate how organizations can be differentiated and described as reinforcer systems. Twenty-seven specific satisfaction scales were regressed on overall job satisfaction, separately for each of five groups of managers from five organizations. For all groups, overall satisfaction was found to be determined mainly by scales concerning challenge of the job and prospects of one's chosen career. Application of decremental stepwise multiple regression procedures to obtain minimum-variable-set equations resulted in different, though overlapping, sets of variables in the equations for the different organizations. These results suggest a way of describing organizations as reinforcer systems, in terms of the specific determinants of overall satisfaction for the organization. 相似文献

An examination of two judgement models, adaptation-level (AL) theory and the theory of signal detection (TSD), was made in terms of their ability to handle data from several voluntary generalization studies. Both models were found to be somewhat inadequate, though in different ways. AL theory was found to be unable to predict amount or slope of the generalization gradient, while TSD was seen to be unable to account for shifts in judgment due to context and frequency effects. A combined AL-TSD model was presented which combines the advantages of each model and offers a good account of both choice and latency data in voluntary generalization 相似文献
