What is it that we lack in everyday life that causes us to value art so highly? This article argues that (almost) all values are to be understood in terms of a needs‐satisfaction system, and hence that the value of art can be understood only with reference to the state of the appreciator prior to engagement with the artwork. Aesthetic appreciation can be analysed as a process, which can be described in empirically based psychological terms, leading to a functional view of aesthetic experience as potentially enhancing the individual's orientation at sensory, cognitive, and interpersonal levels; our motivation is a special form of pleasure. Various objections are then considered, with particular attention to the role of pleasure in connection with tragedy; the relation of art to related cultural pursuits is also briefly indicated. 相似文献

All literature embodies an implicit theory of personality and human nature (Hogan, 1976). The research described here investigates the implicit personality theory embedded in the behavior of 435 characters in 143 canonical Victorian novels. Characters were rated on the Web by 519 scholars and students of 19th-century British literature. Ratings included the characters’ goals, success in achieving goals, mate preferences and strategies, and personality according to the Five Factor Model. Results suggest that novels by Victorian authors largely reflect personality and human nature as understood by modern personality psychology, but Victorian authors amplify the significance of agreeableness and thus, whether intentionally or not, encourage cooperative impulses in readers. 相似文献

Recent research has shown that mind wandering recruits executive resources away from the external task towards inner thoughts. No studies however have determined whether executive functions are drawn away in a unitary manner during mind wandering episodes, or whether there is variation in specific functions impacted. Accordingly, we examined whether mind wandering differentially modulates three core executive functions—response inhibition, updating of working memory, and mental set shifting. In three experiments, participants performed one of these three executive function tasks and reported their attentional state as either on-task or mind wandering at random intervals. We found that mind wandering led to poorer performance in the response inhibition and working memory tasks, but not the set-shifting task. These findings suggest that mind wandering does not recruit executive functions in a monolithic manner. Rather, it appears to selectively engage certain executive functions, which may reflect the adaptive maintenance of ongoing task performance. 相似文献

ObjectivesThe present study was to examine the relationship between exercise type and inhibitory function in older adults using neuroelectric indices.DesignA cross-sectional design was employed in the present study.MethodSixty adults (M = 69.42 years) were categorized into open-skill, closed-skill, and irregular exercise groups according to their history of exercise participation. The participants conducted a flanker task while their behavioral performance and event-related brain potentials were assessed.ResultsThe results indicated that regular exercisers, regardless of exercise type, exhibited a faster reaction time across conditions of the flanker task compared to irregular exercisers. For the P300 amplitude of the open-skill exerciser group, the peak amplitude was larger at the vertex site compared to the frontal site, whereas no site differences were observed in the closed-skill and irregular exerciser groups.ConclusionsThese findings extend current knowledge by suggesting that, for older adults, participation in physical exercise involving increased cognitive demand is associated with better neural efficiency in resource allocation for tasks that require interference control. 相似文献

Physical activity (PA) plays an essential part in the secondary prevention of persons with coronary heart disease (CHD). A substantial amount of PA can be gained through increasing the use of active transport modes (walking or cycling for at least 10 min/day) in CHD patients’ daily routine, benefiting the mortality and morbidity rate as well as the environment. The current study aims to investigate the utility of the Theory of Planned Behaviour (TPB) framework extended with habit strength, in understanding the behavioural intention and the behaviour of using active transport modes during the daily travel routine of CHD patients. A cross-sectional survey was conducted from 131 CHD patients. The behaviour was measured using three self-report methods; 1) scale measure, the walking or cycling frequency, 2) direct ATS (Active Travel Score, PA calculated by the directly reported aggregated time spent per day for walking or cycling for travel purposes), and 3) indirect ATS (PA calculated by combining the duration spent on trips by walking and cycling from the self-reported one-day travel diary). Additionally, the participants completed surveys on the direct measures of TPB constructs and habit strength. The results indicated that the TPB constructs explained a 38% variance in the intention to use active transport modes of CHD patients, by which the variance increased to 59% with the addition of habit strength. On the contrary, different behavioural measures were explained differently by TPB and habit strength. The scale measure of behaviour was best predicted (up to 21%) by TPB and habit strength. However, the direct and indirect measures of behaviour were poorly explained (up to 3% and 10% only, respectively). Habit strength moderated the relationship between behaviour (scale measure) and behavioural intention. Surprisingly, higher behavioural intention resulted in a lower behavioural frequency when the habit strength to be active is low. This suggests a limited control over the behaviour thus indicating the intention-behaviour gap. The current study findings highlight the inconsistent predictive utility of TPB across different types of behavioural self-report measures, targeted at the use of active transport modes in CHD patients. However, considering this study as hypothesis-generating, further research is necessary to replicate and extend these findings. 相似文献

The degree to which each sport modality relies on cognitive visual skills is hitherto under-researched. This study sought to further understanding of the relationship between sport modality and visual search ability, visual working memory, and reasoning. Ninety-five participants took part in the present study. In order to assess visual search ability, we employed the Visual Search Task. Visual working memory was assessed through the Corsi Block Tapping – Backwards Task. Reasoning abilities were assessed through the Cognitive Reflection Task. Results indicate that visual search skills appear to benefit to a higher extent from open-skill sports when compared to closed-skill sports. It is important to emphasize, however, that this result was associated with a small effect size. Moreover, the present findings indicate that closed-skill athletes do not differ in terms of visual search abilities, working memory, and reasoning abilities when compared to control individuals. 相似文献

为探讨挫折情境下自我肯定对执行功能的影响,创设挫折和非挫折情境,采用价值观自我肯定干预,通过Stroop范式和2-back范式分别测量抑制控制和工作记忆的刷新能力。结果发现,挫折情境下的Stroop任务和2-back任务反应时均高于非挫折情境;挫折情境下自我肯定组在Stroop任务和2-back任务上的反应时均显著低于非自我肯定组,而非挫折情境下两组的反应时没有显著性差异;Stroop效应量在情境与肯定条件上的交互作用不显著。结果表明挫折降低了执行功能的任务表现,自我肯定干预能够改善挫折情境下执行功能相关的任务成绩,促进了个体对工作记忆任务的刷新能力和Stroop任务的认知表现,但对抑制控制能力的改善没有明显作用。 相似文献

In a subgroup of patients with mild traumatic brain injury (TBI) residual symptoms, interfering with outcome and return to work, are found. With neuropsychological assessment cognitive deficits can be demonstrated although the pathological underpinnings of these cognitive deficits are not fully understood. As the admission computed tomography (CT) often is normal, perfusion CT imaging may be a useful indicator of brain dysfunction in the acute phase after injury in these patients.In the present study, directly after admission perfusion CT imaging was performed in mild TBI patients with follow-up neuropsychological assessment in those with complaints and a normal non-contrast CT. Neuropsychological tests comprised the 15 Words test Immediate Recall, Trailmaking test part B, Zoo Map test and the FEEST, which were dichotomized into normal and abnormal. Perfusion CT results of patients with normal neuropsychological test scores were compared to those with abnormal test scores.In total eighteen patients were included. Those with an abnormal score on the Zoo Map test had a significant lower CBV in the right frontal and the bilateral parieto-temporal white matter. Patients with an abnormal score on the FEEST had a significant higher MTT in the bilateral frontal white matter and a significant decreased CBF in the left parieto-temporal grey matter. No significant relation between the perfusion CT parameters and the 15 Words test and the Trailmaking test part B was present.In conclusion, impairments in executive functioning and emotion perception assessed with neuropsychological tests during follow up were related to differences in cerebral perfusion at admission in mild TBI. The pathophysiological concept of these findings is discussed. 相似文献
