We discuss evidence indicating that human visual attention is strongly modulated by the potential of objects for action. The possibility of action between multiple objects enables the objects to be attended as a single group, and the fit between individual objects in a group and the action that can be performed influences responses to group members. In addition, having a goal state to perform a particular action affects the stimuli that are selected along with the features and area of space that is attended. These effects of action may reflect statistical learning between environmental cues that are linked by action and/or the coupling between perception and action systems in the brain. The data support the argument that visual selection is a flexible process that emerges as a need to prioritize objects for action. 相似文献

This article examines the complex relationship between culture, values, and ethics in mental health care. Cultural competence is a practical, concrete demonstration of the ethical principles of respect for persons, beneficence (doing good), nonmaleficence (not doing harm), and justice (treating people fairly)—the cornerstones of modern ethical codes for the health professions. Five clinical cases are presented to illustrate the range of ethical issues faced by mental health clinicians working in a multicultural environment, including issues of therapeutic boundaries, diagnosis, treatment choice, confidentiality and informed consent, and the just distribution of limited health care resources. 相似文献

In examining films of lifting movements in a study of the size-weight illusion (Davis & Roberts, 1976), a consistency was noted in the values obtained for the maximum accelerations of the objects lifted. While at first surprising, this finding can be embedded significantly in theories relating to kinesthetic illusions and the perception of weight and to theories on the control of general physical movement. This study was designed to confirm its existence. Twenty-four subjects were filmed lifting four objects differing in size, shape, substance, color, and weight. The film was analyzed frame-by-frame and the data were subjected to a two-way analysis of variance. Subjects, while differing from one another, were consistent in the maximum accelerations they applied to the three heaviest of the four objects. The accelerations of the lightest object differed significantly from the accelerations of the other three, but it seems likely that this was due to the experimental task itself. 相似文献

Abstract A national survey of 289 people from a variety of professions (nurses, social workers, clinical psychologists, psychiatrists, etc) involved in counselling cancer patients and their families within the United Kingdom obtained a response rate of 82%. The primary findings discussed in this paper cover a range of issues, including the working conditions and responsibilities of the counsellors, what professional qualifications they possess, the extent and availability of supervision and support, as well as the types of counselling intervention employed. Particularly disturbing was the fact that only 25% of our sample had any recognised formal counselling qualification and that 75% did not belong to any professional counselling organisation. In view of the wide diversity of qualifications, salary scales, responsibilities and working conditions and practices amongst the respondents, we propose that the National Health Service (NHS) should establish clearer guidelines as to the minimum acceptable qualifications for people employed as oncology counsellors, and that more adequate provision and resources are made available for training and supervision. 相似文献

Through twin studies, research in behavioral genetics has demonstrated significant genetic components in many personality traits. Less research has been done on inheritance of vocational interest preferences, partially because of the lack of a wholistic conceptual model for understanding the relationships among diverse occupational interests. With the development of scales for the Strong Vocational Interest Blank (SVIB) to measure the six cognitive interest styles propounded by Holland, a parsimonious and comprehensive mapping of the occupational world was available and lent itself to the study of measuring inheritance of vocational preferences among twins. Median intraclass correlations for 409 pairs of monozygotic males, tested with the SVIB, was r = .50; for 570 pairs of monozygotic females, r = .55; for 237 pairs of dizygotic males, r = .27; and for 370 pairs of dizygotic females, r= .27. 相似文献

The occurrence of the size-weight illusion is related to the manner in which-objects are lifted. When the SWI occurs, the larger of two objects of equal objective weight is usually lifted with greater acceleration, deceleration, and maximum velocity than the smaller one, but to approximately the same height. These differences are not present when the cans feel equally heavy. The relationship of lifting movements to judgments is consistent with the known behavior of proprioceptors which provide sensory input about muscular and movement events. 相似文献

Two experiments were carried out in an attempt to replicate Lett's (1974) demonstration of visual discrimination learning with a 1-min delay of reward. In Experiment 1, controls for olfactory cues were introduced by testing animals in different orders from day to day and by reversing the positions of the discrimination chambers within days; also, secondary reinforcement effects were precluded by the use of opaque rather than transparent doors to the discrimination chambers. No evidence of learning was found either in a group of rats returned to the home cage during the delay or in a group left in the apparatus during the delay. It was hypothesized that the failure to find improvement in Experiment 1 might have resulted from either the controls for odor cues or from a lack of memory retrieval cues provided by the apparatus. In Experiment 2, both of these hypotheses were tested and neither was supported. The Lett group in Experiment 2 was run according to the exact procedures used by Lett and still no learning was demonstrated. It was concluded that further demonstrations of visual discrimination learning with a 1-min delay of reward will be necessary for the acceptance of the validity of this phenomenon. 相似文献
