We present a method for the development of consensus documents describing the components of genetic evaluation and genetic counseling for various diagnoses. These documents were developed to encourage consistency among genetic professionals in Washington State. Other possible uses of these documents are to provide information regarding genetic evaluations for health care practitioners and payers, and to assist in quality assurance and genetic training programs. A working group of six genetic professionals developed two templates for the critical elements of genetic evaluation and genetic counseling, for clinical (nonprenatal) and prenatal patients. The working group then completed prototype templates for several specific genetic disorders. The templates and prototypes were sent to interested genetic professionals and perinatologists who submitted a total of 76 draft critical elements (CE's) to the working group. At two statewide meetings, participating practitioners modified and unanimously approved the CE templates, then unanimously approved the 21 draft CEs that had been finalized in small group discussions. Approved CE's were distributed to genetic professionals and perinatologists within the state. 相似文献

Subjects indicated for a series of trials whether or not two pictures of common objects were from the same category. Reaction time (RT) was recorded. The pool of stimuli used in the series of trials consisted of two pictures representing each of several categories. Half were S categories, members of which were similar; the other half were D categories, which had dissimilar members (this variable is termed category structure). In Experiments 1 and 3, the similarity manipulation defining category structure was based on the concept of basic level categories (Rosch, Mervis, Gray, Johnson, & Boyes-Braem, 1976). In Experiment 2, category labels were homonyms, and the two members of S or D categories represented one or two senses of the labels, respectively. The principal finding was an effect of category structure (faster RT on trials using stimuli from S categories rather than D categories). These results are interpreted in terms of a model that postulates the use of semantic codes in the task, even on trials where the two stimuli are physically identical. 相似文献

These experiments addressed why, in episodic-memory tests, familiar faces are recognized better than unfamiliar faces. Memory for faces of well-known public figures and unfamiliar persons was tested, not only with old/new recognition tests, in which initially viewed faces were discriminated from dis tractors, but also with tests of memory for specific information. These included: detail recall, in which a masked feature had to be described; orientation recognition, in which discrimination between originally seen faces and mirror-image reversals was required; and recognition and recall of labels for the public figures. Experiments 1 and 2 showed that memory for orientation and featural details was not robustly related either to facial familiarity or to old/new recognition rates. Experiment 3 showed that memory for labels was not the exclusive determinant of the famous-face advantage in recognition, since famous faces were highly recognizable even they were not labelable or when labels were forgotten. These results suggest that the familiarity effect, and face recognition in general, may reflect a nonverbal memory representation that is relatively abstract. 相似文献

In the first study using point-light displays (lights corresponding to the joints of the human body) to examine children's understanding of verbs, 3-year-olds were tested to see if they could perceive familiar actions that corresponded to motion verbs (e.g., walking). Experiment 1 showed that children could extend familiar motion verbs (e.g., walking and dancing) to videotaped point-light actions shown in the intermodal preferential looking paradigm. Children watched the action that matched the requested verb significantly more than they watched the action that did not match the verb. In Experiment 2, the findings of Experiment 1 were validated by having children spontaneously produce verbs for these actions. The use of point-light displays may illuminate the factors that contribute to verb learning. 相似文献

Stimulus fading procedures have repeatedly been demonstrated as effective in shaping a wide variety of new behaviors. Borrowing from this body of research, the behavioral treatment of feeding disorders presents a new area of application for stimulus fading. The purpose of this study is to demonstrate the efficacy of stimulus fading in the treatment of adipsia. Two children who ate solids, but refused all liquids, were participants in the study. Results showed that a five step fading procedure starting with a spoon and thickened liquids, and ending with a cut‐out‐cup, was successful in establishing cup drinking skills for both children. Results of the study suggest that stimulus fading can facilitate feeding skill acquisition. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

We present an overview of a new multidisciplinary research program that focuses on haptic processing of human facial identity and facial expressions of emotion. A series of perceptual and neuroscience experiments with live faces and/or rigid three-dimensional facemasks is outlined. To date, several converging methodologies have been adopted: behavioural experimental studies with neurologically intact participants, neuropsychological behavioural research with prosopagnosic individuals, and neuroimaging studies using fMRI techniques. In each case, we have asked what would happen if the hands were substituted for the eyes. We confirm that humans can haptically determine both identity and facial expressions of emotion in facial displays at levels well above chance. Clearly, face processing is a bimodal phenomenon. The processes and representations that underlie such patterns of behaviour are also considered. 相似文献

How do children learn associations between novel words and complex perceptual displays? Using a visual preference procedure, the authors tested 12- and 19-month-olds to see whether the infants would associate a novel word with a complex 2-part object or with either of that object's parts, both of which were potentially objects in their own right and 1 of which was highly salient to infants. At both ages, children's visual fixation times during test were greater to the entire complex object than to the salient part (Experiment 1) or to the less salient part (Experiment 2)--when the original label was requested. Looking times to the objects were equal if a new label was requested or if neutral audio was used during training (Experiment 3). Thus, from 12 months of age, infants associate words with whole objects, even those that could potentially be construed as 2 separate objects and even if 1 of the parts is salient. 相似文献

This study investigated the relationship between emotion comprehension, grammar comprehension, and working memory capacity in children between 5 and 11 years (n= 130), testing the hypothesis that working memory has a role in the development of emotion comprehension. We replicated the correlation between emotion comprehension and grammar comprehension, and found that working memory capacity correlates with both of these variables (also with age statistically controlled). The significant effect of age on emotion comprehension was eliminated when working memory capacity was co‐varied. In a regression analysis of emotion comprehension scores, when working memory capacity was entered as a predictor, no additional variance was significantly accounted for by grammar comprehension, gender, or age. A structural relations model, in which the paths from working memory capacity to emotion comprehension and from working memory capacity to grammar comprehension account fully for the correlation between grammar and emotion comprehension, fit the data well. However, working memory capacity was not equally related to all components of the Test of Emotion Comprehension (TEC) ( Pons & Harris, 2000 ), the relationship being significant only for some of them. In particular, working memory capacity has a decisive role in the transition from understanding external to mental aspects of emotions. It is concluded that the development of working memory has a considerable impact on the development of emotion comprehension. 相似文献

CONTEXT: The psychosocial impact of arthritis can be profound. There is growing interest in psychosocial interventions for managing pain and disability in arthritis patients. OBJECTIVE: This meta-analysis reports on the efficacy of psychosocial interventions for arthritis pain and disability. DATA SOURCES: Articles evaluating psychosocial interventions for arthritis were identified through Cochrane Controlled Trials, EMBASE, Ovid MEDLINE, and Ovid PsycINFO data sources. STUDY SELECTION: Randomized controlled trials testing the efficacy of psychosocial interventions in arthritis pain management were reviewed. DATA EXTRACTION: Twenty-seven randomized controlled trials were analyzed. Pain intensity was the primary outcome. Secondary outcomes included psychological, physical, and biological functioning. DATA SYNTHESIS: An overall effect size of 0.177 (95% CI=0.256-0.094) indicated that patients receiving psychosocial interventions reported significantly lower pain than patients in control conditions (combined p=.01). Meta-analyses also supported the efficacy of psychosocial interventions for the secondary outcomes. CONCLUSIONS: These findings indicate that psychosocial interventions may have significant effects on pain and other outcomes in arthritis patients. Ample evidence for the additional benefit of such interventions over and above that of standard medical care was found. 相似文献
