The present study assessed the effect of two types of physical exercise on the self reported mood of 64 9 and 10-yr.-old children who responded to a self-report mood meassure after two different types of aerobic exercise of 15 min., and after a 15-min. video. Significant increases in positive mood and significant decreases in negative mood were found after each exercise treatment; however, positive mood decreased and negative mood increased following the video treatment. Interestingly, no significant difference in mean mood scores was found between the two exercise treatments. These data suggest that short bouts of physical exercise have psychological benefits for children.  相似文献

There is limited understanding of the problems associated with repeated neuropsychological assessment in children, including the statistics used to guide decisions about cognitive change. This study investigated the utility of a computerized assessment battery that was specifically designed for the repeated assessment of cognitive function in children. Eighty-seven participants aged 8 to 12 years completed the battery four times within a 2-hour testing session. The results support the application of this assessment battery for measuring cognitive change in children. A novel method for calculating measurement error is employed, and its use in the detection of cognitive change in individual children is discussed. An estimate of the measurement error within each of the tests is provided, and recommendations are made regarding the application of this assessment battery for measuring cognitive change in children.  相似文献

In a human fear conditioning experiment, 32 participants were trained in a differential conditioning procedure with geometrical shapes as CS+ and CS- (four presentations each), and an electric shock as US. Measures of conditioned responding were skin conductance response (SCR) and retrospective US-expectancy ratings. For half of the participants (Generalization Group, GG), the subsequent extinction phase consisted of four nonreinforced presentations of generalization stimuli (GS+ and GS-). Participants from the Extinction control Group received an equal amount of nonreinforced presentations of the CSs. Finally, all participants were tested with the original CSs. The results from both measures clearly show an increase in the size of the discrimination upon the stimulus change after extinction in the GG. Because this pattern is not observed in the Extinction control Group, extinction performance appears to be somehow restricted to the perceptual characteristics of the extinction stimulus. Interestingly, the size of the conditioned SCR discrimination in the GG is not influenced by the stimulus change after acquisition. This observation points to a differential impact of stimulus change after acquisition vs. extinction treatment. The findings are discussed from the theoretical perspective of renewal and the clinical perspective of Return of Fear.  相似文献

Previous research suggests that rats will decrease their consumption of a low-valued substance if a high-valued one will soon be available (anticipatory contrast), but will increase their rate of operant responding for a low-valued substance if a high-valued one will soon be available (positive induction). The present experiments tested whether rats would increase their operant rate of licking or lever pressing for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement was upcoming in the same session. Results indicated that upcoming 32% sucrose increased rates of lever pressing for 1% sucrose, but did not produce similar increases in rates of licking. In fact, upcoming 32% sucrose significantly reduced lick rates in Experiment 2. The present results suggest that the different changes in behavior may be linked to the specific response that the subjects must engage in to obtain the reward (i.e., licking vs. lever pressing), and not to the function of the behavior (i.e., consummatory vs. operant) or to how frequently the substances are available (i.e., continuously vs. intermittently).  相似文献

Performance variability across repeated task administrations may be an important indicator of age-related cognitive functioning. In the present investigation, the authors examined whether age differences and change in inconsistency were related to 6-year (3 occasion) cognitive change. Inconsistency scores were computed from 4 reaction time tasks performed by 446 older adults (54-89 years). Replicating previous cross-sectional results, greater inconsistency was observed for older participants even after controlling for differences in response speed. New longitudinal results demonstrated (a) associations between inconsistency at baseline measurement and 6-year change in cognitive performance; (b) longitudinal change in inconsistency; and (c) intraindividual covariation between 6-year change in inconsistency and 6-year change in level of cognitive function. These findings support the view that performance variability serves as a marker of cognitive aging.  相似文献

Regular exercise is said to have positive effects on mood, especially if the exercise intensity is low to moderate. However, the acute effects resulting from participation in a strenuous competition, such as a marathon race, have been studied less. The present investigation used the Profile of Mood States (POMS) test to measure mood, before and after the 1989 Stockholm Marathon. A total of 106 male runners (mean age 40.0 years), with finishing times between 3h and 3h 45 min participated as subjects. Results showed great changes between pre- and post-marathon scores, most of them significant at the p less than 0.001 level. Furthermore, differences between a faster and a slower group of runners were demonstrated with regard to mood states, even though plasma glucose levels were comparable. It is concluded that participation in a marathon race greatly effects mood, mainly in a more negative way than low to moderately intense exercise does.  相似文献

Prior research on mood management through media consumption has encountered mixed results. This study seeks to address these discrepancies by incorporating time of measurement into the examination of regulatory outcomes and by identifying trait-like cognitive moderators that presumably are involved in the regulation of negative moods. Results showed that sad mood initially fostered longer listening to mood-compatible music but such preference decreased over time, suggesting the merits of considering temporal changes in the mood-repair process. In addition, ruminative trait was found to be a significant factor in how people cope with their sad moods, whereas mood salience was not.  相似文献

Analysis of studies investigating mood-state-dependent retrieval identifies methodological problems that may have contributed to the controversy surrounding the reliability of the effect-in particular, the possible confounding of encoding and retrieval in previous studies. Five experiments are reported investigating the effects of mood on learning and recall. Mood-state-dependent retrieval was observed in Experiment 1a (using Velten's Mood Induction Procedure); Experiment 1b (using a music MIP); and Experiment 1c (using Velten's MIP at encoding and a music MIP at retrieval). Subjects who learned and recalled in different moods had significantly greater decrements in recall than did subjects in the same moods. Experiments 2 and 3 investigated the effect of observable retrieval cues on moodstate-dependent retrieval. In Experiment 2, the presence of observable retrieval cues at recall overrode state-dependent retrieval. In Experiment 3, by manipulating the presence or absence of observable cues at recall, both the occurrence and the erasure of the mood-state dependency was demonstrated.Moodstate during learning andcued recallwas also shownto affect performance in a third session under conditons of free recall.  相似文献

The purpose of this article is to integrate two outstanding problems within the philosophy of science. The first concerns what role aesthetics plays in scientific thinking. The second is the problem of how logically testable ideas are generated (the so-called "psychology of research" versus "logic of (dis)proof" problem). I argue that aesthetic sensibility is the basis for what scientists often call intuition, and that intuition in turn embodies (in a literal physiological sense) ways of thinking that have their own meta-logic. Thus, aesthetics is a form of cognition. Scientists think not in equations or words or other logical abstractions, but emotionally and sensually, using visual and aural images, kinesthetic and other proprioceptive feelings, sensations, patterns, and analogies. These aesthetic forms of thinking have their own logics that I call "synosia", from the root words synaesthesia (a combining of senses) and gnosis, "to know". Synosia denotes understanding that integrates feeling that one knows with feeling what one knows. Eminent scientists universally describe an explicitly secondary process in which such personal knowledge must be "translated" into a formal language, such as words or equations, in order to be communicated to other people. Many of the unsolved problems that philosophers of science (as well as psychologists and artificial intelligence researchers) have had in making sense of scientific thinking have arisen from confusing the form and content of the final translations with the hidden means by which scientific insights are actually achieved.  相似文献

We introduce the term “enclothed cognition” to describe the systematic influence that clothes have on the wearer's psychological processes. We offer a potentially unifying framework to integrate past findings and capture the diverse impact that clothes can have on the wearer by proposing that enclothed cognition involves the co-occurrence of two independent factors—the symbolic meaning of the clothes and the physical experience of wearing them. As a first test of our enclothed cognition perspective, the current research explored the effects of wearing a lab coat. A pretest found that a lab coat is generally associated with attentiveness and carefulness. We therefore predicted that wearing a lab coat would increase performance on attention-related tasks. In Experiment 1, physically wearing a lab coat increased selective attention compared to not wearing a lab coat. In Experiments 2 and 3, wearing a lab coat described as a doctor's coat increased sustained attention compared to wearing a lab coat described as a painter's coat, and compared to simply seeing or even identifying with a lab coat described as a doctor's coat. Thus, the current research suggests a basic principle of enclothed cognition—it depends on both the symbolic meaning and the physical experience of wearing the clothes.  相似文献

Embodied cognition is sweeping the planet. On a non-embodied approach, the sensory system informs the cognitive system and the motor system does the cognitive system’s bidding. There are causal relations between the systems but the sensory and motor systems are not constitutive of cognition. For embodied views, the relation to the sensori-motor system to cognition is constitutive, not just causal. This paper examines some recent empirical evidence used to support the view that cognition is embodied and raises questions about some of the claims being made by supporters.  相似文献

ABSTRACT:

This article evaluates recent evidence for an association between creativity and bipolar mood disorders. Eminent creativity and everyday creativity are distinguished, with high rates of major mood disorders‐particularly bipolar disorders— appearing among eminent creators in the arts. However, among everyday persons, including the 4–5% of the population that may develop a bipolar “spectrum”; disorder and their relatives, it is those with relatively milder mood disorders and normalcy who may show the greatest creative advantage. These seemingly conflicting results are reconciled through comparison of research designs and the creativity and diagnostic variables studied. Evidence regarding mood states that enhance creativity is also considered, both for eminent and everyday creators, and some preliminary results from a study of patients are presented. Here, milder mood elevations were tied most closely to the experience of creativity, although other patterns can exist. Three patterns are examined in terms of 23 mood, cognitive, and behavioral features that Jamison (1989) studied in eminent creators.  相似文献

This study considered the relationship between mood states, prospective memory, and retrospective memory among a non-clinical sample of undergraduate students. Multiple regression analyses with simultaneous entry of variables were undertaken to examine the unique contributions of the alternate memory test and the emotional states to memory test performance. As expected, retrospective free recall performance and anxiety made unique and significant contributions to performance on the prospective memory task. However, only prospective memory performance emerged as a significant predictor of retrospective free recall. It is suggested that none of the mood measures emerged as a significant predictor of retrospective memory performance because they do not account for unique variance. In contrast, the relationship between anxiety and prospective memory appears to be due to factors uniquely associated with anxiety, and unrelated to depression.  相似文献

This is an investigation of belief-value distortion as measured by the correlation between sets of beliefs and values for a given attitude object. Correlations were computed for each subject separately. Initial mood levels and mood changes subsequent to ratings of attitudes to nuclear power were investigated in the first two studies. In Study 1 mood changes were positively correlated with attitude. In Study 2, mood levels were positively correlated both with attitude, optimism, and tendency towards extreme belief-value correlations (belief-value distortion). In a third study, attitudes were studied both towards nuclear power and alcohol. There were no clear relations between the two fields of contents. Mood changes were small and inconsistent. However, tendency to act correlated with both optimism and belief-value distortion, also with the level of attitude kept constant. A model relating mood, optimism, belief-value distortion, and action is suggested.  相似文献

This study analyzes the effects of group membership change on group cognition and performance to determine how groups can simultaneously leverage oldtimers’ collective knowledge and a newcomer’s expertise. Our analysis focuses specifically on the interrelated effects of the two components of a transactive memory system (TMS)—TMS structure and TMS processes—to explain the cognitive mechanisms through which membership change affects group performance. Results from a laboratory study show that groups that experience partial membership change tend to rely on the TMS structure that oldtimers developed in their original group, and that doing so is ultimately detrimental to performance because it creates inefficient TMS processes. Results from a supplemental study indicate that these TMS process inefficiencies can be avoided when oldtimers are instructed to reflect upon their collective knowledge prior to task execution. We discuss the implications for managing group cognition in organizations where membership change is prevalent.  相似文献

How preschool children retrieve hidden objects was examined in two cross-sectional studies. The first was a simple task in which 1- and 3-year-olds saw two treats hidden in their living room. The newly walking infants generally sought the closer treat first, providing evidence for a least-distance spatial strategy. However, this strategy was affected by a tendency to approach the hiding place most recently baited. Three-year-old children used a least-distance strategy regardless of the order of hidings. In Experiment 2, 3- and 5-year-olds saw 12 puzzle pieces hidden in various containers equally spaced within a naturally furnished children's laboratory. Factors in addition to age were the distinctiveness of the containers and a requirement to return to the center of the array after each retrieval. Overall, children of both age groups were quite successful at this task, retrieving 11 of the pieces. However, 3-year-olds were less efficient, retrieving fewer pieces and requiring more searches. Detailed analyses of errors and patterns of choices indicated differential processes in achieving their performance. Three-year-old children showed the use of memories for events, discrimination of classes of hiding places, and efficient spatial biases. Five-year-old children were more likely to exhibit these processes concurrently.  相似文献
