Attentional requirements of walking at various speeds in older adults were examined. Twenty healthy older adults (69.9?±?2.77?years; 8 males) were asked to walk a distance of 10?m at a self-selected speed as well as 30% quicker and 30% slower. Concurrently, reaction time (RT) was evaluated by having participants respond as fast as possible to randomly presented auditory stimuli. Results reveal that an accelerated walking speed generated faster RT than slow and self-selected speeds, while no difference was found between the latter. Faster RTs during an accelerated walking speed may have been precipitated by the reduced equilibrium demands of the task. 相似文献

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested. 相似文献

Age-related differences in timing with breaks 总被引:1,自引:0,他引:1
Two groups of participants differing in age were compared on a time production task during which timing was temporarily interrupted. Produced intervals lengthened with increasing delay before the break occurrence, and the effect was more pronounced in older than in younger adults. A reaction time response to the signal beginning the break period was required also. Older participants responded more slowly to this signal, but they benefited to a greater extent from a lengthening of the time preceding its presentation. These results suggest that performance of older participants is affected by attention sharing and preparation involved in timing with breaks. 相似文献

This study presented the results of a content validity conducted on the French version of the Impact of Event Scale-Revised (IES-R). A panel of three judges proceeded to the evaluation of the items of the IES-R taking into account that it would be completed by an elderly population. The panel evaluated each item's clarity and theoretical pertinence and classified them according to the diagnostic symptoms of the post-traumatic stress disorder (PTSD) of the DSM-5. Results showed that items of the IES-R are quite clear and pertinent theoretically speaking. Regarding the classification of the items describing the criteria for the diagnostic of PTSD, the experts concluded that many items were confusing. Improvement recommendations are presented. 相似文献

The psychic tonus model (Braun and colleagues, 1999, 2002, 2003, 2006) states that the left hemisphere is a "booster" of internal experience and behavior in general, and that the right hemisphere is a "dampener". Twenty-five patients with a "positive" extreme disturbance of body schema (somatoparaphrenia) and 37 patients with a "negative" disturbance of body schema (autotopagnosia or Gerstmann's syndrome), all following a unilateral parietal lesion, were found in the literature and were analyzed to test predictions from Braun's "psychic tonus" model. As expected, patients with a positive syndrome had a right hemisphere lesion significantly more frequently, and those with a negative syndrome had a left hemisphere lesion significantly more frequently. Thus the psychic tonus model of hemispheric specialization, previously supported with regard to psychomotor baseline, libido, talkativeness, memory, auditory and visual perceptual tonus, now incorporates the tonus of representation of the body (body schema) in the parietal lobes. 相似文献

For approximately 150 years, Baha’is in Iran have been persecuted on the basis of their religion. Limitations to aspects of their lives have compelled them to face “civic death” or migrate to other countries. This qualitative pilot study explored the experience of forced migration and how religion attenuates the disruption to the lives of Iranian Baha’is. Adaptive strategies that four participants utilised to re-establish continuity were examined. Participants who were satisfied with their lives developed a way to allow parallel cultural traditions (Iranian and Canadian) to co-exist; those who could not integrate found it difficult to maintain a balance between these traditions. 相似文献
