Monocular depth perception was compared with binocular depth perception in 5- and 7-month-old infants. Reaching was used as the dependent measure. Two objects, identical except in size, were presented simultaneously to each infant. The smaller object was within reach for the infants while the larger object was just beyond reach. The two objects subtended equal visual angles from the infants' observation point. With binocular presentation, 96% of the 7-month-olds' reaches and 89% of the 5-month-olds' reaches were for the nearer object. With monocular presentation, 58% of the 7-month-olds' reaches and 65% of the 5-month-olds' reaches were for the nearer object. The reaching preferences observed in the monocular condition indicated sensitivity to monocular depth information (motion parallax, accommodation, and relative size information were available). Binocular viewing, however, resulted in a far more consistent tendency to reach for the nearer object. This result suggests that the infants' perception of the objects' distances was more veridical in the binocular condition than in the monocular condition.  相似文献

Two measures of job performance of 301 employees of a manufacturing enterprise in Québec (the criteria) were used to assess the stability of predictive validity over time of two specific intelligence tests, OTIS and BETA, whilst the moderating effects of two other variables, tenure and job complexity, were also examined. The predictive validity of the tests was not time-based but when job complexity was considered, the validity increased in relation to the complexity of the job.  相似文献

Conceptual and methodological shortcomings of research on family and interactional psychopathology are owing mainly to the use of vague and ill-defined concepts of communication. Based on a theory of language use and communication within general social and cognitive psychology (e.g., Heider, Mead, Piaget, Rometvet) Blakar has outlined a methodology by which interaction is analyzed in terms of how and to what extent the participants (families) manage or fail to cope with the various prerequisites for successful communication under varying situational conditions. A study illustrating this program is presented: The interaction of twelve families, six with (Group S) and six without (Group N) a schizophrenic member, is analyzed in Blakar's communication conflict situation with respect to the members' ability to decenter and take the perspective of each other. Group S proved significantly more egocentric, their egocentric attitudes resulting, as would be expected, in very inefficient communication. Moreover, Group S were not able to adapt their pattern of communication to the changing situational requirements. Finally, the subtle interplay between the capacities and behavior of the individual members and the family system is illustrated: the egocentrism of the members resulted in "closed systems," and the closed systems hindered adequate feedback, forcing the members to decenter.  相似文献

These recommendations describe the minimum standard criteria for genetic counseling and testing of individuals and families with fragile X syndrome, as well as carriers and potential carriers of a fragile X mutation. The original guidelines (published in 2000) have been revised, replacing a stratified pre- and full mutation model of fragile X syndrome with one based on a continuum of gene effects across the full spectrum of FMR1 CGG trinucleotide repeat expansion. This document reviews the molecular genetics of fragile X syndrome, clinical phenotype (including the spectrum of premature ovarian failure and fragile X-associated tremor-ataxia syndrome), indications for genetic testing and interpretation of results, risks of transmission, family planning options, psychosocial issues, and references for professional and patient resources. These recommendations are the opinions of a multicenter working group of genetic counselors with expertise in fragile X syndrome genetic counseling, and they are based on clinical experience, review of pertinent English language articles, and reports of expert committees. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. The professional judgment of a health care provider, familiar with the facts and circumstances of a specific case, will always supersede these recommendations.  相似文献

These cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of identifying at-risk individuals through cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Cancer Genetic Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Key components include the intake (medical and family histories), psychosocial assessment (assessment of risk perception), cancer risk assessment (determination and communication of risk), molecular testing for hereditary cancer syndromes (regulations, informed consent, and counseling process), and follow-up considerations. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client.  相似文献

This article is the result of an Early Childhood Care and Education undergraduate pilot project through a university on the West Coast of Canada. It weaves together poststructural interpretations and a hermeneutic phenomenological recounting of an experience of inquiring about angels with young children. The angel inquiry became a point of entry into a holistic spiritual pedagogy that attends to the whole of a matter, while also paying attention to the significance of each part. Contributing to the interpretations made in this study is Ted Aoki’s philosophy of the space between where the planned curriculum and the lived curriculum (or lived experiences) meet in a third and overlapping tensional space; Max van Manen’s emphasis on lived experiences as ‘breathing meaning’ also contribute to the choices and interpretations made. Blended through the study are the understandings of Tobin Hart and Kate Adams from their investigations of children’s lived experiences with mystical unseen worlds. The area of invisible mystery proves to be more delicate to negotiate than the world of physical embodiments and the world of complete fantasy of the mind; this is the area of the spiritual – the meeting of body and mind with a third and overlapping space. This space goes by many names and many definitions, but ultimately remains indefinable and intangible. But during the pilot project, meaning did come through the inquiring and through the themes that emerged of ‘who we are’ in relation to angels; race, gender and the role of nurturer; and familial angel ownership. Children yearn for allowing spaces to safely express these ideas about, and experiences with, mystery worlds. It is the connection with the inner life through small moments and engagements with the big life questions that the entangling of the physical, the mental and the spiritual creates the intuitive, integrated heart space of a holistic spiritual pedagogy.  相似文献

Fetal and infant rats can learn to avoid odors paired with illness before development of brain areas supporting this learning in adults, suggesting an alternate learning circuit. Here we begin to document the transition from the infant to adult neural circuit underlying odor-malaise avoidance learning using LiCl (0.3 M; 1% of body weight, ip) and a 30-min peppermint-odor exposure. Conditioning groups included: Paired odor-LiCl, Paired odor-LiCl-Nursing, LiCl, and odor-saline. Results showed that Paired LiCl-odor conditioning induced a learned odor aversion in postnatal day (PN) 7, 12, and 23 pups. Odor-LiCl Paired Nursing induced a learned odor preference in PN7 and PN12 pups but blocked learning in PN23 pups. 14C 2-deoxyglucose (2-DG) autoradiography indicated enhanced olfactory bulb activity in PN7 and PN12 pups with odor preference and avoidance learning. The odor aversion in weanling aged (PN23) pups resulted in enhanced amygdala activity in Paired odor-LiCl pups, but not if they were nursing. Thus, the neural circuit supporting malaise-induced aversions changes over development, indicating that similar infant and adult-learned behaviors may have distinct neural circuits.  相似文献

This study examines the association between Sense of Coherence and anxiety and depression amongst patients at risk of hereditary cancer receiving genetic counseling. When writing this article, 144 patients referred for genetic counseling due to a suspicion of hereditary cancer in the family were recruited for this multicentered longitudinal study on the psychosocial aspects of genetic counseling in Norway. A total of 96 (66%) patients responded to the follow-up survey distributed 6 months after genetic counseling. This survey included the Sense of Coherence-29 Scale, Impact of Event Scale, and Hospital Anxiety and Depression Scale. Multiple regression analyses were applied. Our results show association between cancer-related distress and symptoms of anxiety and depression. Sense of Coherence is significantly associated with both anxiety and depression. The hypothesis of Sense of Coherence buffering cancer-related distress and the possible impact of these findings for genetic counseling are discussed.  相似文献
