What information underwrites visual anticipation skill in dynamic sport situations? We examined this question on the premise that the optical information used for anticipation resides in the dynamic motion structures, or modes, that are inherent in the observed kinematic patterns. In Experiment 1, we analyzed whole-body movements involved in tennis shots to different directions and distances by means of principal component analysis. The shots differed in the few modes that captured most of the variance, especially as a function of shot direction. In Experiments 2 and 3, skilled and less skilled tennis players were asked to anticipate the direction of simulated shots on the basis of kinematic patterns in which only the constituent dynamic structures were manipulated. The results indicated that players predicted shot direction by picking up the information contained in multiple low-dimensional dynamic modes, suggesting that anticipation skill in tennis entails the extraction of this dynamic information from high-dimensional displays. 相似文献

The author explores the relationship between spirituality and religion and human growth and development, specifically examining emotional well-being during adulthood. Dimensions of spirituality to be explored are meaning in life, a transcendent purpose, intrinsic values, and spiritual community. The argument is made that spirituality is related to emotional well-being during adulthood. Implications for further research and relevant information for counselors, psychologists, and educators are included. 相似文献

Although empathic accuracy is considered a stable skill, few individual difference measures consistently predict performance on Ickes’ (e.g., 2001) empathic accuracy measure. Because past work has shown that women are more empathically accurate than men when female gender roles are made salient before an empathic accuracy task, we hypothesized that self-reported communion and related variables might predict empathic accuracy. Participants (194 undergraduates) from a northwestern U.S. university completed an empathic accuracy task and self-report measures of communion and empathy. Communion and empathic concern predicted greater empathic accuracy, but only after controlling for socially desirable responding. The role of communion in empathic inference is discussed, along with the need to include measures of social desirability when examining correlates of empathic accuracy. 相似文献

Semantic memory encompasses knowledge of objects, facts and words. A number of brain regions are probably involved, but the left infero-lateral temporal lobe appears to play a key role. The separability of semantic memory from episodic (or autobiographical) memory is a focus of current debate. Impaired semantic memory is a common feature of Alzheimer's disease but is invariably overshadowed by a profound deficit in episodic memory. In semantic dementia, a rarer disorder associated with focal temporal-lobe atrophy, there is selective loss of semantic memory, characterized by preservation of superordinate knowledge of words, and objects, but loss of finer-grained information. This pattern can be interpreted as a degradation of features from a distributed network of semantic representations. Following Herpes simplex encephalitis, patients sometimes show disproportionate loss of knowledge for natural kinds (e.g. animals) with relative preservation of knowledge about artefacts, this may reflect differential damage to neural systems critical for perceptual as opposed to functional features, perceptual properties being more salient in knowledge about natural kinds. 相似文献

This study examines the long-term efficacy of cognitive-behavioral therapy (CBT) for fear of flying (FOF) after a catastrophic fear-relevant event, the September 11, 2001, terrorist attacks. Participants (N = 115) were randomly assigned to and completed treatment for FOF using 8 sessions of either virtual reality exposure therapy (VRE) or standard exposure therapy (SE) prior to September 11, 2001. Individuals were reassessed in June, 2002, an average of 2.3 years after treatment, with a response rate of 48% (n = 55). Analyses were run on the original data and, using multiple imputation procedures, on imputed data for the full sample. Individuals maintained or improved upon gains made in treatment as measured by standardized FOF questionnaires and by number of flights taken. There were no differences between VRE and SE. Thus, results suggest that individuals previously treated for FOF with cognitive-behavioral therapy can maintain treatment gains in the face of a catastrophic fear-relevant event, even years after treatment is completed. 相似文献

Virtual reality exposure therapy and standard (in vivo) exposure therapy in the treatment of fear of flying 总被引:1,自引:1,他引:0
This controlled clinical trial tested virtual reality exposure (VRE) therapy for the fear of flying (FOF), a relatively new and innovative way to do exposure therapy, and compared it to standard (in vivo) exposure therapy (SE) and a wait list (WL) control with a 6- and 12-month follow-up. Eighty-three participants with FOF were randomly assigned to VRE, SE, or WL. Seventy-five participants, 25 per group, completed the study. Twenty-three WL participants completed randomly assigned treatment following the waiting period. Treatment consisted of 4 sessions of anxiety management training followed either by exposure to a virtual airplane (VRE) or an actual airplane at the airport (SE) conducted over 6 weeks. Results indicate that VRE was superior to WL on all measures, including willingness to fly on the posttreatment flight (76% for VRE and SE; 20% for WL). VRE and SE were essentially equivalent on standardized questionnaires, willingness to fly, anxiety ratings during the flight, self-ratings of improvement, and patient satisfaction with treatment. Follow-up assessments at 6 and 12 months indicated that treatment gains were maintained, with more than 70% of respondents from both groups reporting continued flying at follow-up. Based on these findings, the use of VRE in the treatment of FOF was supported in this controlled study, suggesting that experiences in the virtual world can change experiences in the real world. 相似文献

Anterograde amnesia, a common consequence of transient cerebral ischaemia, has been attributed to cell loss in the hippocampal CA1 subfield. However, variable, widespread damage outside hippocampal CA1 can also occur following ischaemia. We compared the functional consequences of ischaemia and ibotenate acid CA1 lesions on 2 spatial memory tasks (water maze 'place' and 'matching-to-position') to address the possibility that extra-CA1 loss contributes to ischaemia-induced memory deficits in the rat. During place task acquisition, ischaemic rats showed deficits on more measures than ibotenic rats, and during a 1 min probe trial, only ischaemic rats were impaired. On the matching-to-position task, ibotenic rats showed greater impairment than ischaemic rats in terms of one-trial learning, whereas ischaemic rats were more impaired after Trial 2. Ischaemia and ibotenic acid lesions resulted in equivalent CA1 loss, but silver impregnation revealed additional extra-CA1 cell loss in ischaemic rats. Together with the greater behavioural deficits of ischaemic rats, these data indicate a role for extra-CA1 cell loss in ischaemia-induced memory impairments in both animals and humans. 相似文献
