It is often said that contemporary students frequently study while ‘multitasking’. However, this rather diffuse term encompasses situations that vary as to the whether the learner controls the pace at which educational materials are provided. On the basis of prior cognitive research, we hypothesize that this may well be a critical determinant of interference. Three studies required students to read or listen to several short historical narratives and also to engage in five to eight very short conversations (akin to an instant messaging conversation). In Experiment 1, subjects read the narratives; here, multitasking marginally increased total time spent reading the narratives, especially when it occurred at random times. However, final memory for the narratives was not significantly affected. Similar results were obtained when the narratives were presented in audio format and the learner could pause them while conversing (Experiment 2). By contrast, when audio narratives did not pause, interruptions reduced comprehension performance (Experiment 3). Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

In the following study, participants encoded blocked DRM word lists and we varied whether they received information before test about the utility of mnemonic features that potentially discriminate between veridical and false memories. The results of three experiments revealed that this manipulation successfully reduced false recognition of critical theme words. We also found that this manipulation was effective for younger but not older adults. Furthermore, calling attention to the features in test instructions alone was sufficient for reducing false recognition and its effectiveness was not enhanced by also asking participants to rate their phenomenal experience. We argue that providing diagnostic information before test allows participants to establish more accurate expectations about the task and thus improves the efficacy of retrieval and monitoring processes that are subsequently engaged. 相似文献

Both anecdotal and empirical investigations have indicated that childhood sexual abuse may negatively impact one's religiosity as an adult. However, few studies have examined the impact of other forms of abuse on the development of religiosity. In the present study, 167 participants recruited from a Pacific Northwest university completed questionnaires measuring parental religiosity, as well as both physical and emotional abuse history, to assess the impact of these factors on the participants’ maintenance of beliefs taught in the family. Results demonstrated that report of abuse was negatively associated with belief maintenance. Alternatively, parental religiosity was positively associated with belief maintenance, and negatively associated with report of abuse. These findings are discussed in terms of social learning theory and the lifestyle behaviours of religious individuals. 相似文献

A multiple-baseline design was used to examine the influence of an imagery intervention on the performance of swimmers’ times on a thousand-yard practice set. Performance times for four swimmers were collected over a 15-week period during preseason training. The intervention took place over a 3-week period and was introduced after the fourth week of the study. The results revealed that three out of four participants significantly improved their times on the one thousand-yard practice set after being introduced to the imagery intervention. The results are discussed in terms of the implications of using imagery to improve athlete's performance on continuous tasks. 相似文献

The purpose of this study was to examine the main and interactive effects of motivational climate and won-lost percentage upon young athletes’ evaluations of their coaches, enjoyment of their team experience, and perceived parental liking for the coach. A total of 268 male and female youth basketball players, aged 10 to 15 years, completed the Motivational Climate Scale for Youth Sports (Smith, Cumming, & Smoll, in press) and selected attitudinal scales relating to their sport enjoyment and their evaluations of their coach. Regular season won-lost percentages were calculated for each of the 50 teams. Hierarchical linear modeling was used to predict player evaluations of the coach. Attitudes toward the coach were positively associated with perceptions of a mastery-involved climate and negatively associated with perceptions of an ego-involved climate. Won-lost percentages positively predicted players’ evaluations of their coach's knowledge and teaching ability, but accounted for far less attitudinal variance than did the motivational climate measures. Consistent with earlier findings, young athletes’ sport enjoyment, and evaluations of their coach were more strongly related to coaching behaviors than to their team's won-lost record. No significant interactions involving winning and motivational climate were found. 相似文献

The aim of the present study was to describe the frequency of risky drinking among a general urban population survey (n=1379) in South Africa with the help of (Alcohol Use Disorders Identification Test) AUDIT-C scores, CAGE (Cut down, Annoyed, Guilty, Eye-opener) scores and compare the scores with calculated risky drinking in terms of weekly alcohol consumption or heavy episodic drinking. Results indicate 44.4% for men and 25.4% for women as hazardous or harmful drinkers and using the CAGE 44.7% (55% among men and 35.5% among women). AUDIT-C and CAGE cases were more likely to be women than men and were also more likely among Coloureds and Whites than Black Africans and Indians or Asians. This study showed a greater sensitivity of AUDIT to CAGE. 相似文献

In a recent paper, Eckart Förster challenges interpreters to explain why in the first Critique practical reason has a canon but no dialectic, whereas in the second Critique, there is not only a dialectic, but an antinomy of practical reason. In the Groundwork, Kant claims that there is a natural dialectic with respect to morality (4:405), a different claim from those advanced in the first and second Critiques. Förster's challenge may therefore be reformulated as the problem of explaining why practical reason has a canon in the first Critique, a dialectic in the Groundwork, and an antinomy in the second Critique. In this paper, I answer this challenge. I argue that these differences are due to the different aims and scope of the works, and in particular, the different place of the inclinations in their arguments. 相似文献

In two experiments, one hundred ninety-two 3-year-olds, 4-year-olds, and adults heard a novel word for a target object and then were asked to extend the label to one of two test objects, one matching in shape-based object category (the shape match) and the other matching in a property other than shape (the property match). We independently manipulated the lexical form class cues (count noun, adjective) and social-pragmatic cues (point actions, property-highlighting actions) accompanying the label. The impact of these two types of cue on extension differed markedly across age groups. Adults and 4-year-olds extended the word to the property match significantly more often when the term was modeled as an adjective and when it was presented with property-highlighting actions; but adults extended both adjectives and count nouns systematically to the property match when the speaker highlighted the non-shape property, whereas 4-year-olds systematically extended only adjectives to the property match under these conditions. Three-year-olds extended the word to the property match significantly more often when the label was modeled as an adjective but were not significantly affected by the social-pragmatic cues; and they failed to extend either adjectives or count nouns systematically to the property match when the speaker highlighted the non-shape property. We discuss the results in terms of the proposal that word learning draws on cues from multiple sources and the nature of the “shape bias” in lexical development. 相似文献

The two-note fee bee song of the black-capped chickadee (Poecile atricapillus) is sung at many different absolute frequencies, but the relative frequencies, or “pitch ratios”, between the start and end of the fee note (glissando) and the fee and the bee notes (inter-note interval) are preserved with each pitch-shift. Ability to perceive these ratios and their relative salience varies with sex of the bird and setting: while both sexes appear to perceive changes in the inter-note interval, males appear to attend to the glissando in the field, and females appear to attend to both ratios. In this study, we compared directly whether male and female chickadees could discriminate between normal fee bee songs and songs that had one or both of the pitch ratios altered, and whether birds attended to one type of alteration over another. Both sexes learned to discriminate normal from altered songs; songs lacking an inter-note interval were more easily discriminated than songs with only the glissando removed. Females performed slightly better than males, including in the most difficult task with the stimuli lacking the glissando. Our study illustrates the value of using perceptual tasks to directly compare performance between the sexes and to demonstrate the difference between perception of and attention to acoustic features of vocal communication. 相似文献
