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

Based on a motivational perspective of passion, we investigated the associations between passion for the Internet and level of self‐determined motivation toward the couple's relationship. Our results show that an obsessive passion toward the Internet was associated with lower self‐determination in the couple, greater conflict in the relationship, and low levels of dyadic adjustment. In contrast, harmonious passion toward the Internet was associated with greater self‐determination in the couple, less conflict, and greater dyadic adjustment. Results suggest that use of the Internet is not necessarily associated with negative interpersonal outcomes. Rather, it appears that the way the activity has been internalized is associated with how individuals internalize their reasons for behaving in other domains. 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

This study examines the psychometric properties of the French-Canadian Modified PTSD Symptom Scale (MPSS-FC) in a sample of French-Canadian undergraduates. Findings uncovered a 3-dimensional model for the Frequency and Severity scales, which shared factorial invariance. In addition, the MPSS-FC scales had adequate internal consistency and a satisfactory 5-week test-retest reliability. In view of its satisfactory psychometric properties, the MPSS-FC seems promising as a brief screening measure of PTSD. Indeed, the MPSS-FC as a stand-alone measure could be used with a population known to have been exposed to a traumatic event. 相似文献

proposed an intriguing and detailed evolutionary theory of dreams which stipulates that the biological function of dreaming is to simulate threatening events and to rehearse threat avoidance behaviors. The goal of the present study was to test this theory using a sample of 212 recurrent dreams that was scored using a slightly expanded version of the DreamThreat rating scale. Six of the eight hypotheses tested were supported. Among the positive findings, 66% of the recurrent dream reports contained one or more threats, the threats tended to be dangerous and aimed at the dreamer, and when facing a threat, the dreamer tended to take defensive or evasive actions that were possible and reasonable. However, less than 15% of the recurrent dreams depicted realistic and probable situations critical for one's physical survival or reproductive success and the dreamer rarely succeeded in fleeing the threat despite important and appropriate efforts. The findings thus provide mixed support for the threat simulation theory. 相似文献

Based on a sample of incarcerated women in Quebec prisons in 1989, this study focuses on drug use and abuse and its relation to crime with a special concern for age of onset, nature of conviction, previous involvement in criminal activities, motivation, and other related variables. The emerging profile of these subjects is one of drug‐related problems rather than a deep involvement in criminality. Within this population of women prisoners a strong link between drugs and crime is still difficult to establish. In conclusion, it is suggested that future research rely more on qualitative analyses to gather a better understanding of the operating processes. 相似文献
