ABSTRACTThe testing effect refers to improved memory after retrieval practice and has been researched primarily with visual stimuli. In two experiments, we investigated whether the testing effect can be replicated when the to-be-learned information is presented auditorily, or visually?+?auditorily. Participants learned Swahili-English word pairs in one of three presentation modalities – visual, auditory, or visual?+?auditory. This was manipulated between-participants in Experiment 1 and within-participants in Experiment2. All participants studied the word pairs during three study trials. Half of participants practiced recalling the English translations in response to the Swahili cue word twice before the final test whereas the other half simply studied the word pairs twice more. Results indicated an improvement in final test performance in the repeated test condition, but only in the visual presentation modality (Experiments 1 and 2) and in the visual?+?auditory presentation modality (Experiment 2). This suggests that the benefits of practiced retrieval may be limited to information presented in a visual modality. 相似文献

Abstract The first section of the paper reviews the kind of action which unfolds in Plato's Republic, and argues that, from Book II onwards, its character shifts from a genuine dialogue (communicative action) to a more manipulative kind of intercourse (strategic action). While the former kind of action was characteristic of the educational activities of the historical Socrates, the case is made that this kind of action became largely eclipsed in Western education and superseded by the strategic concerns to which Platonist conceptions of learning gave prominence. The Platonist legacy, it is pointed out, had a decisive impact on Western conceptions of learning, even beyond the Enlightenment. These conceptions were largely custodial rather than emancipatory in character. An argument is presented in thirteen steps in the second section of the paper, to establish the case that the kind of action which properly describes the experience of teaching and learning is that of a cultural courtship. A distinction is drawn between honourable and dishonourable forms of courtship, the honourable being a candidate for defence in universalist terms. The practical import of the distinction is considered. Under the title ‘The Dialogue that we Aren't’, the third section reviews postmodern objections ‐ particularly those of Lyotard ‐ to the kind of argument made in the thirteen steps, and the concluding section considers Habermas’ later theories in relation to my own ‘universalist’ argument. 相似文献

The brain is highly sensitive to environmental hypoxia. Little is known, however, about the neuropsychological effects of high altitude residence in the developing brain. We recently described only minor changes in processing speed in native Bolivian children and adolescents living at approximately 3700 m. However, evidence for loss of cerebral autoregulation above this altitude (4000 m) suggests a potential threshold of hypoxia severity over which neuropsychological functioning may be compromised. We conducted physiological and neuropsychological assessments in 62 Bolivian children and adolescents living at La Paz (~3700 m) and El Alto (~4100 m) in order to address this issue. Groups were equivalent in terms of age, gender, social class, schooling, parental education and genetic admixture. Apart from percentage of hemoglobin saturated with oxygen in arterial blood (%SpO(2)), participants did not differ in their basal cardiac and cerebrovascular performance as explored by heart rate, mean arterial pressure, end-tidal carbon dioxide, and cerebral blood flow velocity at the basilar, anterior, middle and posterior cerebral arteries. A comprehensive neuropsychological assessment was administered, including tests of executive functions, attention, memory and psychomotor performance. Participants living at extreme altitude showed lower levels of performance in all executive tests (Cohen effect size = -0.91), whereas all other domains remained unaffected by altitude of residence. These results are compatible with earlier physiological evidence of a transitional zone for cerebral autoregulation at an altitude of 4000 m. We now show that above this threshold, the developing brain is apparently increasingly vulnerable to neuropsychological deficit. 相似文献

Millions of people currently live at altitudes in excess of 2500 metres, where oxygen supply is limited, but very little is known about the development of brain and behavioural function under such hypoxic conditions. We describe the physiological, cognitive and behavioural profile of a large cohort of infants (6–12 months), children (6–10 years) and adolescents (13–16 years) who were born and are living at three altitude locations in Bolivia (~500 m, ~2500 m and ~3700 m). Level of haemoglobin oxygen saturation and end‐tidal carbon dioxide were significantly lower in all age groups living above 2500 metres, confirming the presence of hypoxia and hypocapnia, but without any detectable detriment to health. Infant measures of neurodevelopment and behaviour yielded comparable results across altitude groups. Neuropsychological assessment in children and adolescent groups indicated a minor reduction in psychomotor speed with increasing altitude, with no effect of age. This may result from slowing of underlying brain activity in parallel with reduced cerebral metabolism and blood flow, evidenced here by reduced cerebral blood flow velocity, particularly in the basilar artery, in children and adolescents. The proportion of European, Native American and African genetic admixture was comparable across altitude groups, suggesting that adaptation to high altitude in these children occurred in response to chronic hypoxic exposure irrespective of ethnic origin. Thus, psychomotor slowing is proposed to be an adaptive rather than a deficient trait, perhaps enabling accuracy of mental activity in hypoxic conditions. 相似文献

A large, ethnically diverse, and representative sample of university workers in administrative, instructional, and blue-collar/clerical support categories were administered a battery of questionnaires designed to assess job and nonwork stress, biopsychosocial reactions to stress, emotionality, medical symptoms and utilization, and perceived social support, among other variables. A total of 831 participants returned questionnaires. The principal results showed that job and nonwork stress correlated positively with behavioral, cognitive, and physiological reactions to stress as well as with negative emotionality. Job and nonwork stress correlated meaningfully with medical symptoms; nonwork stress also correlated at a useful level with reported medical utilization. Social support did not generally modulate reports of stress or reactions to stress. It was also found that support staff reported higher levels of nonwork stress and lower levels of work stress, but that 2 measures of job stress did not differentiate administrative and instructional personnel. Younger staff reported higher levels of job and nonwork stress, and females reported higher levels of nonwork stress, irrespective of job category. The results were discussed in terms of their importance for understanding the nature of stress among personnel on the university campus and in relation to prior research. 相似文献

Results from studies using a behavioral high-risk design and approximations to it generally have corroborated the cognitive vulnerability hypothesis of depression, whereas results from remitted depression studies typically have not. Suspecting that design features of previously conducted remitted designs likely precluded them from detecting maladaptive cognitive patterns, the authors conducted a study featuring the remitted design that has been successful in studies of a biological vulnerability for depression. Participants' current depressive symptoms, negative cognitive styles (hopelessness theory), dysfunctional attitudes (Beck's theory), and lifetime prevalence of clinically significant depression were assessed. Participants who had remitted from an episode of clinically significant depression had more negative cognitive styles, but not greater levels of dysfunctional attitudes, than did never depressed individuals. 相似文献

The authors used socioanalytic theory to understand individual differences in people's performance at work. Specifically, if predictors and criteria are aligned by using theory, then the meta-analytic validity of personality measures exceeds that of atheoretical approaches. As performance assessment moved from general to specific job criteria, all Big Five personality dimensions more precisely predicted relevant criterion variables, with estimated true validities of .43 (Emotional Stability), .35 (Extraversion-Ambition), .34 (Agreeableness), .36 (Conscientiousness), and .34 (Intellect-Openness to Experience). 相似文献
