ABSTRACT Young and older adults performed verbal and spatial storage-only and storage-plus-processing working memory tasks while performing a secondary finger tapping task, and the effects on both the maximum capacity (measured as the longest series correct) and the reliability (measured as the proportion of items correct) of working memory were assessed. Tapping tended to produce greater disruption of working memory tasks that place greater demands on executive processes (i.e., storage-plus-processing tasks compared to storage-only span tasks). Moreover, tapping produced domain-general interference, disrupting both verbal and spatial working memory, providing further support for the idea that tapping interferes with the executive component of the working memory system, rather than domain-specific maintenance processes. Nevertheless, tapping generally produced equivalent interference effects in young and older adults. Taken together, these findings are inconsistent with the hypothesis that age-related declines in working memory are primarily attributable to a deficit in the executive component. 相似文献

While an historical glance through the sport psychology literature reveals an interest in performance excellence since its beginning, a focus of personal excellence has been a more recent trend. This review will address the relationships between performance and personal excellence. More specifically, we question whether performance excellence in high-level sport, by virtue of the exceptional demands on the elite athlete, occurs at the expense of development in personal excellence or whether performance excellence is possible only through personal excellence. Furthermore, we propose that the field may reconcile these ideals in the future through an athlete-centered sport model. This model is defined by the philosophy that developmentally appropriate sport can be used as a vehicle for enhancing overall well-being and the acquisition of lifelong skills. Performance excellence, therefore, co-exists in the same environment as personal excellence. The implications of implementing an athlete-centered sport system for athletes and coaches and for the research and practice of those in sport psychology will be addressed. 相似文献

It is often parents who introduce their children to competitive sports and parents who then provide remarkable emotional and material support across their children's athletic careers (Bloom, 1985; Côté, 1999). Considerable research documents athletes’ retirement experiences (Baillie, 1993; Baillie & Danish, 1992; Svoboda & Vanek, 1982; Werthner & Orlick, 1982), yet none explores the effects of retirement on parents. The purpose of this study was to examine the effects of athletes’ disengagement from sport on parents. In-depth interviews were conducted with six parents of former female elite gymnasts who had been retired for three to five years and the data analyzed inductively (Côté, Salmela, Baria, & Russell, 1993; Lally & Kerr, 2005; Miller & Kerr, 2002, 2003). Their daughters’ withdrawal from gymnastics and their own immediate disengagement from the world of elite sport had a tremendous impact on the participants’ personal and social relationships, leaving them struggling with weighty self-doubts over their failure to intervene with abusive coaches. 相似文献

The experience of self is partially a narrative of one's history; without memory, there is no self. Central to personal histories are accounts of significant relationships and their successes and failures. Accounts of failed relationships tend to gravitate toward two narrative themes: selfpity and guilt. This essay explores some aspects of the nature of guilt and self-pity, the different forms in which they surface, and their relationship to each other. 相似文献

Potocki-Lupski syndrome (PTLS) or duplication 17p11.2 syndrome is a newly characterized condition causing a variety of health problems with variable severity, including failure to thrive in infancy and childhood, hypotonia, structural heart anomalies, cognitive impairments, speech and learning difficulties, and autism. Due to its recent clinical characterization little is known about the psychosocial impact of this condition on patients and their families. This study evaluated whether parental psychosocial outcomes were associated with children’s PTLS disease severity. Parents of 58 children with PTLS completed a cross-sectional survey that assessed parental stress, quality of life, and coping skills. Parental functioning was associated with greater severity of feeding difficulty and with lower severity of a cardiovascular defect. Findings from this study highlight potential support needs of parents of children affected by PTLS and suggest ways in which these needs may be addressed. 相似文献

The 1997 discovery of free fetal DNA in maternal plasma launched clinical researchers’ efforts to establish a reliable method for non-invasive prenatal testing for fetal genetic conditions. Various methods, including, but not limited to, massively parallel sequencing (MPS) and selective analysis of cell-free fetal DNA in maternal plasma, have recently been developed as highly sensitive and specific noninvasive screening tools for common fetal chromosome aneuploidies. Incorporating these new noninvasive technologies into clinical practice will impact the current prenatal screening paradigm for fetal aneuploidy, in which genetic counseling plays an integral role. The National Society of Genetic Counselors (NSGC) currently supports Noninvasive Prenatal Testing/Noninvasive Prenatal Diagnosis (NIPT/NIPD) as an option for patients whose pregnancies are considered to be at an increased risk for certain chromosome abnormalities. NSGC urges that NIPT/NIPD only be offered in the context of informed consent, education, and counseling by a qualified provider, such as a certified genetic counselor. Patients whose NIPT/NIPD results are abnormal, or who have other factors suggestive of a chromosome abnormality, should receive genetic counseling and be given the option of standard confirmatory diagnostic testing. 相似文献

International exchange training in genetic counseling is increasing, but research examining these experiences is lacking. In this study 309 genetic counseling students and genetic counselors completed an anonymous survey investigating six major research questions: (1) How prevalent are international genetic counseling experiences? (2) What types are pursued and why? (3) What supports and barriers exist? 3) What are the demographic characteristics of individuals accruing international experience? (5) Does international experience promote professional development? and (6) Do genetic counseling students and professionals perceive international experiences as beneficial? Most respondents were Caucasian females born in one of 25 countries. The most prevalent experiences involved either clinical observation or clinical training. Common motivations for pursuing international experience were personal growth, exposure to a different healthcare system, and travel opportunities. Outcomes included professionally-relevant experience and personal growth. Barriers included finances, limited availability of opportunities, and for those without international experience, family responsibilities. Additional findings, practice and training implications, and research recommendations are provided. 相似文献

Are Older Adults More Dependent on Visual Information in Regulating Self-Motion Than Younger Adults?
Patricia G. Anderson Bart Nienhuis Theo Mulder Wouter Hulstijn 《Journal of motor behavior》2013,45(2):104-113
Older adults look at the ground more while they are walking than younger adults do. In the present study, the effect of blocking that exproprioceptive visual information on the walking pattern of older adults was investigated. The first 0.75 m of the floor in front of healthy young adults (n = 10, mean age = 26.0 years) and 2 groups of older adults (n = 10, mean age 65.7 years; and n = 9, mean age = 75.9 years) was occluded. The dependent variables were step velocity, step length, and step frequency. The effect of the manipulation on those kinematic variables increased with age. The older adults had a significant increase in velocity and step length. The possible use of optic flow information from the ground to regulate the velocity of self-motion is discussed. 相似文献
