A theory is proposed to explain the linkages between individual task goals and performance. Two cognitive constructs are postulated to mediate between task goals and performance:performance expectancy and performance valence. It is asserted that an individual's task goal has a positive influence on performance expectancy and a negative influence on performance valence. Performance expectancy is proposed to have a positive influence on performance while performance valence is proposed to have a negative influence on performance. Task ability is hypothesized to influence performance both directly and indirectly through its influence on performance expectancy. A laboratory experiment was designed to test the causal model proposed by the theory. A path analysis on the data from this experiment provides strong support for the model, with performance expectancy, performance valence, and task ability predicting 63% of the variance in performance on the laboratory task. 相似文献

An experiment was conducted to investigate the effect of spatial separation on interference effects in pitch memory. Subjects compared the pitches of two tones that were separated by a sequence of eight interpolated tones. It was found that error rates were lower in sequences where the test and interpolated tones were presented to different ears, compared with sequences where they were presented to the same ear; however, this effect of spatial separation was not large. It is concluded that differences in spatial location can enable the focussing of attention away from the irrelevant tones and so reduce their disruptive effect, but that this occurs only to a limited extent. 相似文献

A detailed analysis of a unique speech disturbance, marked by the frequent appearance in the speech stream of a meaningless intrusive syllable, is presented. Following a lengthy thoracic surgery, an American English speaking patient began to speak with non-English prosodic patterns, which evolved to a conspicuous intrusion in his speech of the syllable /sis/. This syllable and its variants were attached to words in a manner which conformed to the regular phonological rules in English (for formation of plural, possessive, and third person singular morphemes). The distribution and frequency of the intrusive syllable are described, and possible explanations for the abnormal occurrence of this particular syllable are discussed. 相似文献

To extend and clarify the nature of the perceptual processes used by sport experts to perceive schematic sport information, two experiments used schematic football diagrams that varied in structure (structured vs. unstructured) and complexity (complex vs. easy). The primary objective was to examine and characterize the nature of the perceptual structures (chunks) that are initially encoded, stored, and subsequently retrieved. In Experiment 1, compared with nonexperts, experts recalled larger perceptual structures following the initial stimulus presentation of structured stimuli only, replicating the recall findings of previous research in other skill domains. Experiment 2 used a long-term memory recognition task and a sorting task. Experts had superior recall and recognition of structured stimuli only, along with more discriminating sorting criteria of perceptual structures within long-term memory. This suggests that experts possess a highly refined semantic network or organized, structured schematic information. This research extends and clarifies the similarities between the perceptual processes of experts in sport (i.e., football) and experts in skill domains that require obvious cognitive involvement (i.e., chess). The results are discussed with reference to the perceptual and conceptual chunking hypotheses. It is proposed that sport experts' knowledge of a conceptual category enables them to retrieve elements using a "generate-and-test process." 相似文献

When their newborns were 2 weeks of age, 53 mothers completed the activity items of the Rothbart questionnaire. Two weeks later, the same mothers were interviewed at home with regard to their newborns' activity level, using the Thomas, Chess and Birch guidelines and the Carey and McDevitt global rating. Prior to analysis, responses to the instruments were clustered into the contexts of feeding, sleeping, bathing, dressing, and daily activities. Though none of the questionnaire clusters correlated with the global rating, daily activities were convergent between the questionnaire and interview responses. In contrast, all five of the situational contexts for the interview were related positively to the global rating of activity. Results are discussed in light of the apparent contextual influence on maternal ratings of temperament at 1 month. 相似文献

E. T. Gershoff (2002) reviewed processes that might mediate and contexts that might moderate the associations between corporal punishment (CP) and child behaviors and provided an account of the methodological weaknesses of the research reviewed in her meta-analyses. In this examination of Gershoff, the authors argue that the biases and confounds in the meta-analyses further limit any causal inferences that can be drawn concerning the detrimental "effects" of CP on associated child behaviors. The authors suggest that undesirable child outcomes are associated with CP because the construct marks inept harsh parenting and conclude that although the harmful effects of physical abuse and other extreme punishments are clear, a blanket injunction against spanking is not justified by the evidence presented by Gershoff. 相似文献

Personally familiar proper names are relatively successfully processed in the human right hemisphere; or, the missing link 总被引:1,自引:0,他引:1
Responding to our abstract in Brain and Language (Ohnesorge & Van Lancker, 1999), which proposed that famous proper nouns are successfully processed in both cerebral hemispheres, Schweinberger, Landgrebe, Mohr, and Kaufmann (2001) claimed that the "link" between personal names and the right hemisphere is "illusory." Ohnesorge and Van Lancker (2001) further described six experimental studies in which LVF/RH recognition of famous proper nouns was influenced by task conditions and stimulus familiarity. Here presenting two more experiments performed to explore the refutation presented by Schweinberger et al., this article confirms an ability of the right hemisphere to recognize famous proper nouns and explains why appropriate stimulus development and task conditions are essential in furthering our understanding of the role of the right hemisphere in processing personal relevance. 相似文献
