Functional magnetic resonance imaging (fMRI) was used to examine differences between children (9–12 years) and adults (21–31 years) in the distribution of brain activation during word processing. Orthographic, phonologic, semantic and syntactic tasks were used in both the auditory and visual modalities. Our two principal results were consistent with the hypothesis that development is characterized by increasing specialization. Our first analysis compared activation in children versus adults separately for each modality. Adults showed more activation than children in the unimodal visual areas of middle temporal gyrus and fusiform gyrus for processing written word forms and in the unimodal auditory areas of superior temporal gyrus for processing spoken word forms. Children showed more activation than adults for written word forms in posterior heteromodal regions (Wernicke's area), presumably for the integration of orthographic and phonologic word forms. Our second analysis compared activation in the visual versus auditory modality separately for children and adults. Children showed primarily overlap of activation in brain regions for the visual and auditory tasks. Adults showed selective activation in the unimodal auditory areas of superior temporal gyrus when processing spoken word forms and selective activation in the unimodal visual areas of middle temporal gyrus and fusiform gyrus when processing written word forms. 相似文献

In the United States Reserve Officer Training Program, cadets attend a month-long camp, where they are evaluated on leadership ability. The purpose of this study was to assess the experiences of cadets upon their return. Through semistructured interviews, with 25 cadets, 3 distinct higher order themes emerged: (a) perceived difficulty of the Leadership Development and Assessment Course, (b) psychological skills required for success, and (c) social climate experienced. Furthermore, upon completion of general inductive analysis, cadets’ responses were compared to their leadership score, thereby highlighting how salient aspects of leadership manifest themselves through cadets’ behaviors and performances. 相似文献

This experiment was designed to examine the effect of resistance exercise of different workloads on subsequent psychological states. Participants, 54 undergraduate students (34 male, 20 female), were randomly assigned to one of three groups: (a) low workload resistance exercise (50% of 1 RM), (b) high workload resistance exercise (80% of 1RM), or (c) a no exercise control. Resistance exercise consisted of three sets of five repetitions for three free-weight exercises: the bench press, overhead press, and dumbbell row. Psychological state was indicated by the Exercise-Induced Feeling States Inventory (Gauvin & Rejeski, 1993) and was assessed prior to exercise and at 10, 25, and 40 min post exercise. Data were analyzed via a 3 (group) x 4 (time) ANOVA with repeated measures on the second factor. All exercise participants experienced an increased sense of revitalization, which persisted for a greater extent in low rather than high workload participants. None of the groups reported changes over time in positive engagement or tranquility. In addition, while exercise groups did report a reduction in physical exhaustion during recovery, this improvement did not differ from no exercise controls nor did it differ between exercise groups. Thus, weight lifting appears to result in a sense of revitalization, an effect whose duration may be impacted by exercise workload. 相似文献

A religious prosociality stereotype exists such that religiosity and prosociality are presumed to be positively associated, as evidenced by proxy measures such as personality traits. However, studies using self- and peer-ratings of Agreeableness and Conscientiousness have not simultaneously controlled for the religiosity of the participant and the target. One hundred and sixty students completed measures of religiosity in a prescreening survey. Later, participants rated an array of targets, including a Christian and an atheist, on adjectives corresponding to Agreeableness and Conscientiousness. Regardless of participant religiosity, atheist targets were rated as being lower in Agreeableness and Conscientiousness relative to those labeled as Christians. This bias was greater for highly religious participants. This effect was mediated by perceptions of the morality of the target independent of participants' broader attitudes concerning the target's religious group. Implications are discussed. 相似文献

Cognitive psychologists have begun to address how motivational factors influence adults' performance on cognitive tasks. However, little research has examined how different motivational factors interact with one another to affect behavior across the life span. In the current study, the authors examined how children perform on a classification task when placed in a regulatory fit or mismatch. Nine-year-old children performed a classification task in which they either gained or lost points for each response. Additionally, children were given either a global promotion focus (trying to earn a gift card) or a prevention focus (trying to avoid losing a gift card). Previous work indicates that adults in this task tend to perform better when there is a match (or fit) between the incentive to gain, or avoid losing, a global reward, and the more local task reward structure to either maximize points gained or minimize points lost on a trial-by-trial basis. Unlike adults, 9-year-olds perform better in the promotion condition than in the prevention condition regardless of task reward structure. Possible explanations for the differences between adults' and children's performance are discussed as are possible applications for academic settings. 相似文献

Are we humans drawn to the forbidden? From jumbo-sized soft drinks to illicit substances, the influence of prohibited ownership on subsequent demand has made this question a pressing one. We know that objects that we ourselves own have a heightened psychological saliency, relative to comparable objects that are owned by others, but do these kinds of effects extend from self-owned to “forbidden” objects? To address this question, we developed a modified version of the Turk shopping paradigm in which “purchased” items were assigned to various recipients. Participants sorted everyday objects labeled as “self-owned”, “other-owned,” and either “forbidden to oneself” (Experiment 1) or “forbidden to everyone” (Experiment 2). Subsequent surprise recognition memory tests revealed that forbidden objects with high (Experiment 1) but not with low (Experiment 2) self-relevance were recognized as well as were self-owned objects, and better than other-owned objects. In a third and final experiment, we used event-related potentials (ERPs) to determine whether self-owned and self-forbidden objects, which showed a common memory advantage, are in fact treated the same at a neurocognitive–affective level. We found that both object types were associated with enhanced cognitive analysis, relative to other-owned objects, as measured by the P300 ERP component. However, we also found that self-forbidden objects uniquely triggered an enhanced response preceding the P300, in an ERP component (the N2) that is sensitive to more rapid, affect-related processing. Our findings thus suggest that, whereas self-forbidden objects share a common cognitive signature with self-owned objects, they are unique in being identified more quickly at a neurocognitive level. 相似文献

We report initial validity analyses of the Brief Adolescent Life Event Scale (BALES). This instrument addresses negative and positive events pertinent to the well being of adolescent boys and girls, and is designed for use in studies utilizing an extended research protocol. Selection of items was guided by emerging perspectives on positive psychology , action theory , and personality vulnerability , as well as by new developments in statistical modeling theory. The 36 items of the scale tap negative and positive events, each of which addresses interpersonal and achievement life domains. Using a large sample of early-adolescents ( N = 895), we confirmed the hypothesized structure that includes four domain-level latent factors (i.e., negative interpersonal events, negative achievement events, positive interpersonal events, positive achievement events), and two overarching factors (negative events and positive events). Indices of positive and negative events predicted adolescent depressive symptoms in expected ways, and positive events buffered the effect of negative events on depressive symptoms. These findings encourage an informed use of the BALES and highlight considerations involved in the development of brief measures of stress and coping processes. 相似文献

In the Multi-Item Localization task (MILO; Thornton & Horowitz, 2004), observers are asked to find an ordered sequence of targets. We can measure the influence of both past actions and future plans on search for the current target. Our previous work with static search arrays found evidence for both retrospective and prospective memory. Responding to a target eliminated its influence on subsequent responses, while observers consistently planned ahead at least one item into the future. Here we asked whether these effects were based in location- or object-based reference frames. We used dynamic arrays in which observers had to search for multiple moving targets. Our results suggest that observers can still plan ahead effectively in this dynamic environment, indicating that future target objects can be tracked as they change position. However, memory for previous targets is essentially eliminated, suggesting that locations, not objects, were being tagged in our previous work. 相似文献
