The influence of functional social support on executive functioning in middle-aged African Americans
Sims RC Levy SA Mwendwa DT Callender CO Campbell AL 《Neuropsychology, development, and cognition. Section B, Aging, neuropsychology and cognition》2011,18(4):414-431
Social support has a positive influence on cognitive functioning and buffers cognitive decline in older adults. This study examined the relations between social support and executive functioning in middle-aged adults. A community-based sample of African Americans completed the Interpersonal Support Evaluation List, a measure of functions of social support, and two measures of executive functioning, the Stroop Color and Word Test and the Wisconsin Card Sorting Test (WCST). Hierarchical regression analyses were used to explore the hypothesis that different facets of perceived social support influence performance on measures of executive functioning. After controlling for age, gender, and education, social support facets including belonging support, self-esteem support, appraisal support, and tangible support were significant predictors of Stroop performance. In addition, tangible support significantly predicted WCST performance. These findings add to previous literature on social support and cognition; however, findings for middle-aged adults are unique and suggest that social support has a positive influence on some executive functions in African Americans prior to old age. 相似文献

Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves. In order to compare variations in P300 measurements, a control group paired by age and gender to the group of stutterers, was included in the study. Findings suggest that the group of stutterers presented a significant decrease in stuttering severity after the fluency treatment program. Regarding P300 measurements, stutterers and their controls presented results within normal limits in all testing situations and no significant statistical variations between pre and post treatment testing. When comparing individual results between the testing situations, stutterers presented a higher average decrease in wave latency for the right ear following treatment. The results are discussed in light of previous P300 event-related potentials and functional imaging studies with stuttering adults.Educational objectives: The reader will learn about and be able to describe the: (1) use of P300 event-related potentials in the study of stuttering; (2) differences between stuttering and non-stuttering adults; and (3) effects of behavioral fluency treatment on cerebral activity in stuttering speakers. 相似文献

The relationships between authoritarianism and attitudes about arranged marriage were studied in Bangladesh and Korea. According to regression analyses (N = 417), authoritarianism was positively related to support for arranged marriages in closed-ended and open-ended responses. Authoritarianism was also negatively related to open-ended discussions about the importance of love in selecting a partner and in the importance of emotional connection in establishing a relationship. Replicating prior results from the US on women, authoritarianism was related to desires to marry individuals who were gender-typed, traditional, and with narrow interests. Despite some differences in patterns of relationships due to gender and country of origin, the findings support the general hypothesis that authoritarians are invested in maintaining the traditions of their culture. 相似文献

Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early sitting was found to be lower for infants with developmental delay in the anterior-posterior axis, but not in the medial-lateral axis. Spectral analysis showed higher frequency features in the postural sway of early sitting of infants with typical development, suggesting a faster control mechanism is active in infants with typical development as compared to infants with delayed development, perhaps activated by near-fall events. 相似文献

Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this
communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those
who are perceived by study participants as health information gatherers, disseminators, and blockers within families with
Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23–56 years, enrolled in a Breast Imaging
Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational
Map (CEGRM). Purposive sampling ensured that participants varied according to numbers of participating family members e.g., ranging from 1 to 6. Eighty-nine women from 42 families (1–8 relatives/family) participated. They collectively designated
65 blockers, both male and female. Situational factors, beliefs, attitudes and cultural traditions, privacy and protectiveness
comprised perceived reasons for blocking intra-family health communications. Longitudinal data collected over 4 years showed
families where blocking behavior was universally recognized and stable over time, as well as other families where blocking
was less consistent. Self-blocking was observed among a significant minority of participating women. Blocking of health communications
among family members with HBOC was variable, complex, and multifaceted. The reasons for blocking were heterogeneous; duration
of the blocking appeared to depend on the reasons for blocking. Blocking often seemed to involve bi-directional feedback loops,
in keeping with Lepore’s Social Constraints and Modulation Theory. Privacy and protectiveness predominated as explanations
for long-term blocking. 相似文献

Abstract The study explores the reliability, validity, and measurement invariance of the Video game Addiction Test (VAT). Game-addiction problems are often linked to Internet enabled online games; the VAT has the unique benefit that it is theoretically and empirically linked to Internet addiction. The study used data (n=2,894) from a large-sample paper-and-pencil questionnaire study, conducted in 2009 on secondary schools in Netherlands. Thus, the main source of data was a large sample of schoolchildren (aged 13-16 years). Measurements included the proposed VAT, the Compulsive Internet Use Scale, weekly hours spent on various game types, and several psychosocial variables. The VAT demonstrated excellent reliability, excellent construct validity, a one-factor model fit, and a high degree of measurement invariance across gender, ethnicity, and learning year, indicating that the scale outcomes can be compared across different subgroups with little bias. In summary, the VAT can be helpful in the further study of video game addiction, and it contributes to the debate on possible inclusion of behavioral addictions in the upcoming DSM-V. 相似文献

This paper explores the idea of possible proto-experiences of the prenatal child in the context of Bion's model of container/contained. The physical configuration of the embryo/foetus contained in the maternal uterus represents the starting point for an enquiry into the unborn child's possible experiences of its state of being contained in a container. The paper takes into consideration the sensory dimensions of auditory, tactile and kinaesthetic levels of awareness of the prenatal child in relation, respectively, to the maternal voice and the uterine environment. The author's hypothesis is that concrete prenatal experiences of containment may have their mental counterpart in the development of a proto-mental container and memory, the existence of which can be observed in the newborn infant. It is also suggested that prenatal proto-experiences of containment may prepare the child for further postnatal realisations of the pre-conception of containment and represent the experiential basis for the encounter with the breast. Observations of newborn babies in an obstetric ward, as well as the observation of a prematurely born child, seem to confirm the idea that the intrauterine experience of container/contained plays a role in the child's prenatal development. The meaning of prenatal thumb-sucking is explored in terms of the model of container/contained at a part-object level. An observation of the play of a three-year-old child offers material for further thought about the meaning and function of the introjected configuration of container/contained for the development of a sense of identity and symbolic thinking. The clinical case of an autistic child who survived a threatened miscarriage shows how the emotional containment in psychotherapy allowed the formerly inaccessible nameless dread to re-emerge and be represented and shared. 相似文献

Continuous performance tests (CPTs) are widely used in the assessment and study of attention deficit hyperactivity disorder (ADHD). Although CPTs have reliably found differences between children with ADHD and normal controls, discriminating between children with ADHD and children with subclinical levels of behavioral or cognitive problems is a more clinically relevant and difficult endeavor. Additionally, most studies use convenience samples from clinical care settings that may not represent the ADHD population as a whole. The current study assessed the utility of a clinically used CPT, the Test of Variables of Attention (TOVA), in distinguishing between children with ADHD and children with subclinical levels of attention/behavior problems. Participants constituted a representative sample of elementary school students at high risk for ADHD, including 116 children with ADHD and 51 subclinical controls. Results found no significant differences between the ADHD and subclinical group on CPT variables, and CPT performance did not reliably predict group membership. Implications of the findings are discussed. 相似文献

Contemporary education is awakening from a crisis that has held the development of its potential and its relevance at bay for well over a century. Revolutions in science and spirituality are emerging a new relational intelligence that demands commensurate educational paradigms for its blossoming into daily engagements with life and the world around us. At the same time as people are leading increasingly interconnected lives, aware of and often participating in the narratives of people and ecosystems in other parts of the planet, information and communications technologies are increasingly integrating with and serving to mediate the human experience. This article explores the power of this confluence at the current nexus of civilizational demands in the context of increased planetary stresses and destabilizations. The case is made for a thrivable education praxis that draws on these emergent aspects of our developmental potential and emphasizes the importance of functional conviviality as an operational principle of learning for life. 相似文献
