A behavioural programme to treat psychological distress following mastectomy for breast cancer is described. The first 10 patients to be treated were randomly allocated to two treatment groups: Behavioural Programme Only or Behavioural Programme + Drugs (antidepressant medication). Both groups showed improvement over treatment, but the Behavioural Programme + Drugs group appeared to maintain their improvement better.  相似文献

Three studies compared the efficacy of various treatments for public-speaking incompetence. These effects were evaluated for the target behavior as well as for generalization effects across situations (conversations), settings (different sizes and types of audiences) and time (6-month follow-up). The first study showed that Self-instructional Training, either alone or in combination with other procedures, produced little or no benefits. The second study demonstrated the superiority of a Skills Training program over flooding therapy, while the final study failed to detect any enhancement of treatment benefits for the addition of home-practice to the Skills Training. In the first two studies generalization occurred across the three dimensions (settings, situations and time), while in the final study it was shown that the program was effective for a clinical population as well as recruited volunteers.  相似文献

Voice onset time in aphasia: Thai II. Production   总被引:1,自引:1,他引:0  
The aim of this study was to investigate voice onset time (VOT) production in homorganic word-initial stops in Thai in order to explore the nature of speech production deficits across clinical varieties of aphasia. Thai exhibits a three-category distinction in bilabial (/b,p,ph/) and alveolar (/d,t,t,h/) stops, and a two-category distinction in velar (/k,kh/) stops. Subjects included three Broca asphasics, one transcortical motor asphasic, two global asphasics, one conduction aphasic, one Wernicke aphasic, one nonaphasic dysarthric patient, one right-brain-damaged patient, and five normal controls. Test stimuli consisted of eight monosyllabic real words. The results of VOT measurements indicated that Broca and global asphasics exhibited a more severe production disorder than Wernicke, conduction, or transcortical motor asphasics. The right-brain-damaged patient showed no impairment in VOT production. Comparisons are drawn to earlier studies of VOT production in aphasia in two-category languages. Issues concerning the underlying basis of the production deficit for nonfluent aphasics, fluent aphasics, and nonaphasic dysarthrics as well as the relation between perception and production of VOT are discussed.  相似文献

A unilateral cerebral dominance model predicts that speech comprehension will be disrupted after injection of sodium amytal into one hemisphere but not after the other. This model was supported when an auditory receptive task involving relatively nonredundant stimuli similar to that contained in the Token Test (E. DeRenzi & L. Vignolo, 1962, Brain, 85, 665–687) was administered to 17 epileptic patients undergoing bilateral amytal injections.  相似文献

Three versions of Piaget's water-level-horizontality task (multiple choice, drawing, and apparatus tests) were administered to 121 female and 74 male adult volunteers. Sex differences and container orientation effects were replicated. Men were more accurate than women and horizontal and vertical container orientations evoked more accurate responses than oblique orientation. Reliability estimates ranged from .78 to .97 and correlations among the measures ranged from .78 to .88. The relative merits of alternative water-level testing and scoring methods and the orientation and type of stimuli to be used are discussed.  相似文献

In the present essay, the fact that preferences for visual novelty during infancy are related to later performance on intelligence tests was interpreted to mean that intelligence is continuous from infancy. It was suggested that the bases of both continuity and the general factor in intelligence reside in the same small set of basic cognitive processes. It was also noted that intelligent behavior on the part of the infant raises a question about the relative importance of automatic and effortful processes in intelligence. The development of a valid test of infant intelligence was seen as an aid to clarifying the role of hereditary and environmental influences on intelligence and in furthering our understanding of mental retardation. In brief, the manner in which infants distribute their attention to novel and previously exposed stimuli reveals the origins of cognition. The origins of cognition are the origins of intelligence.  相似文献
