Subjects wore goggles with prisms that laterally displaced the visual field (rightward by 11.4°) and with full view of the limb engaged in paced (2-s rate) sagittal pointing at either an implicit (“straight ahead of the nose”) target (Experiment 1) or an explicit (positioned leftward by 11.4°) target (in Experiment 2). In experimental conditions, subjects performed a secondary cognitive task (mental arithmetic) simultaneously during target pointing. In control conditions, no cognitive load was imposed. Aftereffect measures of adaptation to the prismatic displacement were not substantially different when problem solving was required, but terminal error of the exposure pointing task was reliably affected by cognitive load. These results are consistent with the hypothesis of separable mechanisms for adaptive coordination and adaptive alignment. Adaptive coordination may be mediated by strategically flexible coordinative linkage between sensory–motor systems (eye–head and hand—head), but spatial alignment seems to be mediated by adaptive encoders within coordinatively linked subsystems. If the coordination task involves predominately automatic processing, coordinative linkage can be frequent enough under cognitive load for substantial realignment to occur even though exposure performance (adaptive coordination) may be less than optimal. 相似文献

Differences among workers and workplace stressors both contribute to perceiving work as stressful. However, the relative importance of these sources to work stress is not well delineated. Moreover, the extent to which work stress additionally reflects unique matches between specific workers and particular job stressors is also unclear. In this study, we use generalizability theory to specify and compare sources of variance in stress associated with police work. US police officers (N?=?115) provided ratings of 60 stressors commonly associated with policing duties. Primary and secondary stress appraisal ratings reflected differences among officers in tendencies to generally perceive work stressors as stressful (14–15% officer effect), and also agreement among officers in viewing some stressors as more stressful than others (18–19% stressor effect). However, ratings especially reflected distinct pairings of officers and stressors (38–41% interaction effect). Additional analyses revealed individual differences and stressor characteristics associated with each variance component, including an officer?×?stressor interaction – compared to officers low in neuroticism, highly neurotic officers provided lower primary appraisal ratings of stressors generally seen as not serious, and also higher primary appraisal ratings of stressors that were seen as serious. We discuss implications of the current approach for the continued study of stress at work. 相似文献

Little is known about levels of physical activity and attendance at phase IV community-based Cardiac Rehabilitation (CR) programs following completion of exercise-focussed, hospital-based phase III CR. This study aims to test, compare and combine the predictive utility of the Common-Sense Self-Regulation Model (CS-SRM) and the extended Theory of Planned Behaviour (TPB) with action planning for two rehabilitation behaviours: physical activity and phase IV CR attendance. Individuals diagnosed with coronary heart disease (n = 103) completed baseline measures of illness perceptions, intentions, perceived behavioural control (PBC), action planning and past physical activity in the last week of a phase III CR program, and 95 participants completed follow-up measures of physical activity and attended phase IV CR (objectively confirmed) 2 months later. Only one predictor (PBC/cyclical timeline) significantly predicted levels and change of physical activity. While illness perceptions were not predictive of phase IV CR attendance, the extended TPB model showed good predictive power with action planning and intention as the most powerful predictors. Amongst participants who planned when and where to attend phase IV CR at the end of phase III rehabilitation, 65.9% subsequently attended a phase IV CR program compared to only 18.5% of those who had not made a plan. This study adds to our understanding of cardiac rehabilitation behaviour after completion of health service delivered programs. Comparing theoretical models and rehabilitation behaviours contributes to the development of behaviour theory. 相似文献

This study analyzes the type of responses that children between 4 and 5 years of age give to different tasks: conservation, classification and tasks of the theory of mind (ToM). Types of responses were observed with the Observation of Cognitive and Meta-cognitive Skills Inventory, which identifies: attention, receptive and expressive language, planning processes, and meta-cognitive processes. Significant differences were found according to the variable age in: (a) the use of attentional strategies in performance of ToM tasks, (b) the use of receptive and expressive language in the performance of all tasks, (c) the use of planning processes in the performance of conservation tasks; and (d) the use of meta-cognitive processes to solve ToM tasks. 相似文献

Data are limited regarding barriers to care among women, with or at risk for hereditary breast and ovarian cancer (HBOC),
following genetic counseling in the community setting. Using a telephone survey, we retrospectively addressed perceptions
of post-genetic counseling medical care and barriers to care among 69 at-risk women from the non-academic setting. Of these,
all agreed that following cancer screening recommendations was better than not following them; none felt recommendations were
too difficult to follow; all believed screening would help keep them healthy; 57% believed screening would prevent cancer.
Twenty-five percent noted discomfort with breast imaging; 29% found ovarian cancer screening uncomfortable. Close to a quarter
of participants reported difficulty deciding whether or not to undergo risk-reducing mastectomy while 10% noted difficulty
deciding for or against bilateral salpingo-oophorectomy. There were no perceived major barriers to care, although 38% felt
that screening reminders would be helpful, and 10% needed more help in following through with care. Overall, participants
believed that they were benefiting from their post-genetic counseling medical care. This work identified HBOC-related support
needs to include: informational resources that promote improved understanding of cancer risk and high-risk management; screening
reminder systems; and decision support tools. 相似文献
