Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.  相似文献

Abstract

This study examined discrepancies between subjective and objective measures of state anxiety as a function of test anxiety in undergraduates. Under evaluative stress conditions, state anxiety was assessed in terms of (a) self-reported cognitive and somatic anxiety, (b) behavioral reactivity (motor and facial tension, avoidance comments and avoidance of eye contact), (c) physiological arousal (heart rate and skin resistance), and (d) cognitive and motor task performance. Participants high in test anxiety showed disproportionately greater self-reported than objective state anxiety. In contrast, those low in test anxiety showed lower self-reported than objective anxiety. The high- and the low-test-anxiety groups differed only in self-reported emotional reactivity. In line with current cognitive theories of anxiety, overestimation of reactivity in high-test anxiety, as well as underestimation in low-test anxiety, are conceptualized as a hypervigilance bias and an avoidance bias, respectively, in processing internal cues, i.e., prioritization and inhibition of attention to one's own behavioral and physiological signs of distress.  相似文献

Suppose our ordinary notion of truth is ‘inconsistent’ in the sense that its meaning is partly given by principles that classically entail a logical contradiction. Should we replace the notion with a consistent surrogate? This paper begins by defusing various arguments in favor of this revisionary proposal, including Kevin Scharp’s contention that we need to replace truth for the purposes of semantic theorizing (and thus, in particular, to formulate the inconsistency theory of truth itself). Borrowing a certain conservative metasemantic principle from Matti Eklund, the article goes on to build a positive case for the opposite policy: retaining truth as-is. The thought is basically that bivalence for the bulk of what we say in the course of ordinary, scientific, and philosophical inquiry should suffice to justify keeping ‘true’. Two versions of the story are told: one more philosophical, drawing on an analogy to Lewis’ response to Putnam’s paradox; the other more technical, invoking a deviant strand of mathematical work on the semantic paradoxes.  相似文献

Very young children have difficulty transferring what they view onscreen to their offscreen worlds. This study examined whether familiarizing toddlers with a character would improve toddlers' performance on a subsequent seriation task. Toddlers were randomly assigned to one of three conditions: (1) a familiarized character condition where toddlers viewed character-based videos and engaged in character-based play over a 3-month period before viewing the seriation video demonstration; (2) an unfamiliarized character condition where the toddler only saw the seriation video demonstration; and (3) a no-exposure control group where the toddler did not see the seriation video demonstration or have any involvement with the character. All toddlers were tested on the same seriation task at age 21 months, with the familiarized character group beginning the study at age 18 months and the other groups participating only at age 21 months. Toddlers in the familiarized character condition, but not the unfamiliarized character condition, completed the seriation task significantly better than the no-exposure control group. Within the familiarized character condition, toddlers who nurtured the character during play subsequently had higher seriation scores. The results suggest that meaningful relationships with media characters can help toddlers learn early mathematical skills.  相似文献

When a moving target is tracked visually, spatial and temporal predictions are used to circumvent the neural delay required for the visuomotor processing. In particular, the internally generated predictions must be synchronized with the external stimulus during continuous tracking. We examined the utility of a circular visual-tracking paradigm for assessment of predictive timing, using normal human subjects. Disruptions of gaze–target synchronization were associated with anticipatory saccades that caused the gaze to be temporarily ahead of the target along the circular trajectory. These anticipatory saccades indicated preserved spatial prediction but suggested impaired predictive timing. We quantified gaze–target synchronization with several indices, whose distributions across subjects were such that instances of extremely poor performance were identifiable outside the margin of error determined by test–retest measures. Because predictive timing is an important element of attention functioning, the visual-tracking paradigm and dynamic synchronization indices described here may be useful for attention assessment.  相似文献

The types of relationship between happiness, personality and psychopatholgy are assessed in an available sample (n = 321, adults, both sexes). Empirical results from two happiness scales and two questionnaires, one of personality (NEO-PI-R) and other of personality disorders (Loranger's scale), do not confirm the Diener's threshold hypothesis, that makes a distinction between optimum and maximum happiness; or the Seligman's supposition, that assumes that happiness has no limits; The main results are: a) negative affect (Neuroticism) is negatively related to happiness across its full range; b) Extraversion and Openness to experience are positively related to happiness across its full range; c) in the rest of the basic personality factors, relationships are not linear, though not in the sense anticipated by Diener, and d) in personality disorders, the tendencies observed diversify according to the type of disorder, and the type of happiness factor. On most occasions, the close relationship between personality disorders and the Neuroticism dimension is verified in a consistent manner. These results are discussed within the context of clinical psychology, and the general theory about happiness.  相似文献

The ability to predict future events in the environment and learn from them is a fundamental component of adaptive behavior across species. Here we propose that inferring predictions facilitates speech processing and word learning in the early stages of language development. Twelve‐ and 24‐month olds’ electrophysiological brain responses to heard syllables are faster and more robust when the preceding word context predicts the ending of a familiar word. For unfamiliar, novel word forms, however, word‐expectancy violation generates a prediction error response, the strength of which significantly correlates with children's vocabulary scores at 12 months. These results suggest that predictive coding may accelerate word recognition and support early learning of novel words, including not only the learning of heard word forms but also their mapping to meanings. Prediction error may mediate learning via attention, since infants’ attention allocation to the entire learning situation in natural environments could account for the link between prediction error and the understanding of word meanings. On the whole, the present results on predictive coding support the view that principles of brain function reported across domains in humans and non‐human animals apply to language and its development in the infant brain.

This study explored the lived experiences of fertility treatment and care by South African women with infertility. A total of 21 women from different age and ethnic groups (age range = 26 to 41; whites = 53%, coloured = 47%) were interviewed for the study. The women responded to semi-structured interviews on their lived experiences of fertility treatment and care whilst undergoing treatment. The data were analysed using thematic analysis. Four main themes were identified in the study; including: lack of compassionate care from treatment care providers, the need for infertility clinics to integrate psychosocial support care, a need for continuing education for fertility staff, as well as financial support resourcing. Participants expressed a need for health care staff at fertility clinics to be more attentive to their emotional and psychological needs. In addition, participants perceived a need for psychosocial care as a result of the distressing nature of the treatment process. The women also felt that some health care staff lacked technical knowledge about the fertility treatments and this left them deprived of crucial information. The costly nature of fertility treatment presented as an added burden for participants. Overall, participants seemed to require a more individualised and patient centred form of fertility care.  相似文献

Establishment in urbanized environments is associated with changes in physiology, behaviour, and problem-solving. We compared the speed of learning in urban and rural female common mynas, Acridotheres tristis, using a standard visual discrimination task followed by a reversal learning phase. We also examined how quickly each bird progressed through different stages of learning, including sampling and acquisition within both initial and reversal learning, and persistence following reversal. Based on their reliance on very different food resources, we expected urban mynas to learn and reversal learn more quickly but to sample new contingencies for proportionately longer before learning them. When quantified from first presentation to criterion achievement, urban mynas took more 20-trial blocks to learn the initial discrimination, as well as the reversed contingency, than rural mynas. More detailed analyses at the level of stage revealed that this was because urban mynas explored the novel cue-outcome contingencies for longer, and despite transitioning faster through subsequent acquisition, remained overall slower than rural females. Our findings draw attention to fine adjustments in learning strategies in response to urbanization and caution against interpreting the speed to learn a task as a reflection of cognitive ability.  相似文献

We evaluated five competing hypotheses about what predicts romantic interest. Through a half‐block quasi‐experimental design, a large sample of young adults (i.e. responders; n = 335) viewed videos of opposite‐sex persons (i.e. targets) talking about themselves, and responders rated the targets' traits and their romantic interest in the target. We tested whether similarity, dissimilarity or overall trait levels on mate value, physical attractiveness, life history strategy and the Big Five personality factors predicted romantic interest at zero acquaintance and whether sex acted as a moderator. We tested the responders' individual perception of the targets' traits, in addition to the targets' own self‐reported trait levels and a consensus rating of the targets made by the responders. We used polynomial regression with response surface analysis within multilevel modelling to test support for each of the hypotheses. Results suggest a large sex difference in trait perception; when women rated men, they agreed in their perception more often than when men rated women. However, as a predictor of romantic interest, there were no sex differences. Only the responders' perception of the targets' physical attractiveness predicted romantic interest; specifically, responders' who rated the targets' physical attractiveness as higher than themselves reported more romantic interest.
