Postural stability and hand preference as constraints on one-handed catching performance in children
Angelakopoulos GT Davids K Bennett SJ Tsorbatzoudis H Grouios G 《Journal of motor behavior》2005,37(5):377-385
Effects of postural state and hand preference as constraints on 1-handed catching performance were investigated in different ability groups of children aged 9-10 years. On the basis of pretest data, the authors classified 48 participants into groups of good, intermediate, and poor catchers (n = 16 in each) and asked them to perform 1-handed catches with their preferred and nonpreferred hands while standing and sitting. The good catchers' performance was not affected by the imposed postural constraints but did improve when they used the preferred hand. A similar effect of hand preference was evident in the intermediate and poor catchers, but there was also an effect of postural constraint. Independent of hand preference, intermediate catchers' performance while seated improved significantly compared with that during standing. For poor catchers, there was an interaction between hand preference and posture; significant improvement was evident only when they used the preferred hand in the sitting condition. The finding that manipulation of posture and hand preference affected performance outcomes indicates that perceptual skill is not the only influence on catching performance in children. Manipulation of those key constraints may facilitate the acquisition of catching skill, but more research is needed to determine the permanence of those effects. 相似文献

Results of previous studies of courtship and mating in Japanese quail (Coturnix japonica) suggest that females avoid conspecific males because, while courting and mating, males engage in behaviors that are potentially injurious to females. However, prior experiments provided no direct evidence that females avoided harassing males. Here the authors show that a female quail choosing between a previous sex partner and an unfamiliar male avoids the former if he engaged in relatively many potentially injurious acts while courting and mating, (Experiments 1 and 2) and that males behaving aggressively toward mates are less likely than are gentler males to fertilize the females' eggs (Experiment 3). Male sexual harassment appears to be a tactic both aversive to female quail and relatively ineffective in fertilizing them. 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

Genetic Cancer Risk Assessment and Counseling: Recommendations of the National Society of Genetic Counselors 总被引:4,自引:0,他引:4
Trepanier A Ahrens M McKinnon W Peters J Stopfer J Grumet SC Manley S Culver JO Acton R Larsen-Haidle J Correia LA Bennett R Pettersen B Ferlita TD Costalas JW Hunt K Donlon S Skrzynia C Farrell C Callif-Daley F Vockley CW;National Society of Genetic Counselors 《Journal of genetic counseling》2004,13(2):83-114
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

Witte‐Townsend and DiGiulio explore some of the dimensions of knowing that children, teachers and parents may engage together during story‐time. They reflect on some of their own long‐term relationships with children and children's books, especially Phoebe Gilman's Something from nothing (published in 1992) and Simms Taback's Joseph had a little overcoat, published in 1999. The authors probe issues such as why children ask to hear a favourite story over and over and why they suddenly abandon all interest and move on to a new book. They explore the meaning of the silences that sometimes arise during story‐time, pooling around the young listeners as the last words of the book are read. Witte‐Townsend and DiGiulio remind us of the value of literature in the lives of children and they affirm that the reading and re‐reading of favourite stories enables the understanding of complex human issues and contributes significantly to social, emotional and spiritual growth. 相似文献

Psychologists have an opportunity to offer their expertise at a time when health care settings are beginning to recognize the importance of behaviorally based interventions for improving health and health care. The authors review the changing patterns of health and illness that have led to an increased interest in the role of patient and provider behavior and discuss the many advantages of using health care settings as prevention sites. Examples of successful behaviorally based prevention programs are presented, along with the evidence supporting the cost-effectiveness of such programs. Challenges presented by working in health care settings are described. Throughout, the authors emphasize the multiple opportunities for psychologists' involvement across a wide variety of health care delivery sites. 相似文献

Multiple measures of three of the factors (capacity, strategies, and metamemory) hypothesized to cause improvements in memory with age were obtained from 179 children in kindergarten to second grade (younger: ages 5-8) or third and fourth grade (older: ages 8-11) during nine sessions of testing. Confirmatory factor analysis was computed separately for each age group. Results suggested that the fit of the three-factor model was statistically significantly better than a one-factor, general memory model for both age groups. However, the fit indices were borderline, and there was not sufficient evidence for a metamemory factor for younger children. The factors that influence memory performance may differ with age. 相似文献

In this paper I discuss the clash of values between the Old Order Amish community of Ontario and the dominant social paradigm in agriculture. Land-use and agricultural regulations, designed for an industrial style of agriculture, are experienced as a threat to the survival of the Old Order Amish agricultural social economy and community. The paper describes how I have worked with the Old Order Amish to respond to these challenges and to create public policies that will allow them to maintain their human and agricultural diversity and small-scale sustainable farm practices. Four case studies illuminating the oppressive land-use regulations along with the emancipatory responses to the oppression are examined. The social transformation themes include principles and processes for community psychologists, land-use planners, and community economic development practitioners to consider. The article has heuristic value for a practice-based approach to social change. 相似文献
