Three studies examined cross-cultural differences in empathic accuracy (the ability to correctly infer another's emotional experience) within the context of different relationships. East-West cultural differences in self-construal were hypothesized to differentiate levels of empathic accuracy across relationship types. In contrast to the independent self prevalent among members of Western cultures, members of Eastern cultures generally view the self as interdependent with those with whom they have a relationship. Easterners, relative to Westerners, are more concerned with the thoughts or feelings of close others and less concerned with the thoughts or feelings of those with whom they have no relational link (i.e., strangers). Across three studies, the authors found that East Asians, compared with European Americans, made more accurate inferences regarding the emotions of close others (i.e., friends), but less accurate inferences regarding the emotions of strangers. Furthermore, individual differences in interdependent self-construal among East Asians predicted the degree of empathic accuracy. 相似文献
The purpose of this paper was to investigate total joint rotational stiffness (JRS) and relative muscle contributions to JRS with varying extensor moment demands. It was hypothesized that greater co-activation of the flexors at lower levels of moment would result in greater JRS, relative to moment demands. It was also hypothesized that the flexors would have greater relative JRS contributions at lower moment levels. Twelve male participants generated isometric extensor moments about the knee at varying intensities, during plateau and ramping (up and down) conditions. Electromyography was used to estimate individual muscle forces, which were used to calculate JRS about three orthogonal axes. Orthogonal trend analysis revealed a linear relationship (p<.001) between moment and JRS, about all axes. The vastus lateralis provided the greatest JRS about all axes. Of the flexors, the semimembranosis provided the most JRS about the flexion/extension (FE) and axial (AX) axes. However, while most muscle activity increased linearly, the gastrocnemious lateral (GL) had an interaction between condition and moment. Despite an extensor moment, the GL had minor contributions about the FE axis (1.2%), and it was postulated that this increase in activation was to stabilize about the VV axis, where its contribution was as high as 18.9%. 相似文献
The detailed dynamics of action simulation was investigated using the occluder paradigm: a point light actor (PLA) was shown, then briefly occluded from view, during which period action simulation was generated. Following occlusion, the PLA reappeared, either a progression of the motion as it should be post-occlusion or temporally shifted earlier/later. Participants made judgements on whether the reappearing PLA was too early or too late to be a correct continuation (Experiments 1 and 3) or whether it was a veridical continuation or not (Experiment 2). Over three experiments we asked how action simulation is affected by motion information before, during and after occlusion. Reducing motion presented before occlusion retained the accuracy of action simulation judgements. Presenting 4 frames (67 ms) of PLA motion during the occluder duration dynamically updates or altogether regenerates the action simulation. Reducing the duration of the test motion after the occluder decreases judgement precision, which we interpret as a limitation in the process of postdictive motion judgments. Overall, this is further evidence that the action simulation process is remarkably adapted to making human motion predictions. 相似文献
Objective: Preoperative anxiety is often assessed using general anxiety measures; existing specific measures might lack content coverage and/or are not psychometrically validated. This study aimed to develop a new self-report measure of surgery-specific anxiety and test its psychometric properties.
Design: The surgical anxiety questionnaire (SAQ) was developed from themes identified in qualitative research and reviewed by an interdisciplinary expert team. It was administered preoperatively to 135 patients (56% female, mean age 51) on the day of surgery alongside additional measures of preoperative anxiety, state anxiety, perceived stress, depression and social desirability. Follow-up assessment was conducted immediately post-surgery and two weeks post-surgery (n?=?114) to examine recovery and predictive validity of the scale.
Results: Factor analysis revealed a three component structure, including: concerns about health (six items), concerns about recovery (four items) and concerns about procedures (four items). Three additional items of relatively high concern were retained in the total score (17 items). The SAQ displayed good reliability, validity (content, construct and predictive) and adequate overall psychometric properties.
Conclusions: Preliminary results suggest that the SAQ is a promising tool for measuring preoperative anxiety and predicting recovery. Recommendations for future research include employing a confirmatory factor analysis and examining test-retest reliability. 相似文献
Attention deficit hyperactivity disorder (ADHD), its existence and treatment, is a contentious matter. The dominant view in medicine considers that ADHD is a psychiatric disorder. My position is to challenge this from a social relational orientation. I explore here a critique of the psychiatric disease model of causation and treatment, particularly the use of medication. A series of prejudices based on a political and social constructionist orientation are offered to address the ethics, politics and practice implications of the practitioner critical of the biomedical model of diagnosis and treatment especially the use of medication. This device is employed in order to invite critical reflection and further debate in a field dominated by the medical and genetic arguments in support of ADHD as a psychiatric disease. The implications of more open debate are explored, together with directions for more politically and ethically informed practice with children and their families. 相似文献
