Infants who have more power within the gamma frequency range at rest develop better language and cognitive abilities over their first 3 years of life (Benasich et al., 2008). This positive trend may reflect the gradual increase in resting gamma power that peaks at about 4 years (Takano & Ogawa, 1998): infants further along the maturational curve may exhibit both increased resting gamma power and more advanced language and cognitive function. Similar to other neural characteristics such as synaptic density, resting gamma power subsequently decreases with further development into adulthood (Tierney, Strait, O'Connell & Kraus, 2013). If previously reported relationships between resting gamma power and behavioral performance reflect variance in maturation, at least in part, negative correlations between resting gamma and behavior may predominate in later developmental stages, during which resting gamma activity is decreasing. We tested this prediction by examining resting gamma activity and language‐dependent behavioral performance, reflected by a variety of reading‐related tests, in adolescents between the ages of 14 and 15 years. Consistent with our predictions, resting gamma power inversely related to every aspect of reading assessed (i.e. reading fluency, rapid naming, and basic reading proficiency). Our results suggest that resting gamma power acts as an index of maturational progress in adolescents. 相似文献

Intimate Partner Violence and Subsequent Depression: Examining the Roles of Neighborhood Supportive Mechanisms 下载免费PDF全文

This study examines the direct effects of neighborhood supportive mechanisms (e.g., collective efficacy, social cohesion, social networks) on depressive symptoms among females as well as their moderating effects on the impact of IPV on subsequent depressive symptoms. A multilevel, multivariate Rasch model was used with data from the Project on Human Development in Chicago Neighborhoods to assess the existence of IPV and later susceptibility of depressive symptoms among 2959 adult females in 80 neighborhoods. Results indicate that neighborhood collective efficacy, social cohesion, social interactions, and the number of friends and family in the neighborhood reduce the likelihood that females experience depressive symptoms. However, living in areas with high proportions of friends and relatives exacerbates the impact of IPV on females’ subsequent depressive symptoms. The findings indicate that neighborhood supportive mechanisms impact interpersonal outcomes in both direct and moderating ways, although direct effects were more pronounced for depression than moderating effects. Future research should continue to examine the positive and potentially mitigating influences of neighborhoods in order to better understand for whom and under which circumstances violent relationships and mental health are influenced by contextual factors. 相似文献

Counselors’ decision‐making processes have received little attention in the literature. The purpose of this study was to ascertain the ethical decision‐making practices of counselors working in the field. The results of a phenomenological study indicate that linear models and an orientation to professional ethical guidelines learned in graduate training serve as a foundation, yet not a practical guide, in professional ethical decision making. The authors found that 4 themes guide counselors’ ethical decision making: personal values, clients’ best interest, transparency in decision making, and perceptions of formal training and practice. Implications for practice and counselor education are provided, with recommendations for future research. 相似文献

Long‐term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid‐level deficits such as contour integration and motion coherence, to high‐level face and object agnosia. Yet it is unclear whether training during adulthood, at a post‐developmental stage of the adult visual system, can overcome such developmental impairments. Here, we visually trained LG, a developmental object and face agnosic individual. Prior to training, at the age of 20, LG's basic and mid‐level visual functions such as visual acuity, crowding effects, and contour integration were underdeveloped relative to normal adult vision, corresponding to or poorer than those of 5–6 year olds (Gilaie‐Dotan, Perry, Bonneh, Malach & Bentin, 2009). Intensive visual training, based on lateral interactions, was applied for a period of 9 months. LG's directly trained but also untrained visual functions such as visual acuity, crowding, binocular stereopsis and also mid‐level contour integration improved significantly and reached near‐age‐level performance, with long‐term (over 4 years) persistence. Moreover, mid‐level functions that were tested post‐training were found to be normal in LG. Some possible subtle improvement was observed in LG's higher‐order visual functions such as object recognition and part integration, while LG's face perception skills have not improved thus far. These results suggest that corrective training at a post‐developmental stage, even in the adult visual system, can prove effective, and its enduring effects are the basis for a revival of a developmental cascade that can lead to reduced perceptual impairments. 相似文献

Previous studies indicate that at least some aspects of audiovisual speech perception are impaired in children with specific language impairment (SLI). However, whether audiovisual processing difficulties are also present in older children with a history of this disorder is unknown. By combining electrophysiological and behavioral measures, we examined perception of both audiovisually congruent and audiovisually incongruent speech in school‐age children with a history of SLI (H‐SLI), their typically developing (TD) peers, and adults. In the first experiment, all participants watched videos of a talker articulating syllables ‘ba’, ‘da’, and ‘ga’ under three conditions – audiovisual (AV), auditory only (A), and visual only (V). The amplitude of the N1 (but not of the P2) event‐related component elicited in the AV condition was significantly reduced compared to the N1 amplitude measured from the sum of the A and V conditions in all groups of participants. Because N1 attenuation to AV speech is thought to index the degree to which facial movements predict the onset of the auditory signal, our findings suggest that this aspect of audiovisual speech perception is mature by mid‐childhood and is normal in the H‐SLI children. In the second experiment, participants watched videos of audivisually incongruent syllables created to elicit the so‐called McGurk illusion (with an auditory ‘pa’ dubbed onto a visual articulation of ‘ka’, and the expectant perception being that of ‘ta’ if audiovisual integration took place). As a group, H‐SLI children were significantly more likely than either TD children or adults to hear the McGurk syllable as ‘pa’ (in agreement with its auditory component) than as ‘ka’ (in agreement with its visual component), suggesting that susceptibility to the McGurk illusion is reduced in at least some children with a history of SLI. Taken together, the results of the two experiments argue against global audiovisual integration impairment in children with a history of SLI and suggest that, when present, audiovisual integration difficulties in this population likely stem from a later (non‐sensory) stage of processing. 相似文献

Research on the effectiveness of multidisciplinary teams has been equivocal. In an attempt to understand when a team’s professional heterogeneity (PH) is positively related to innovation (INN), we proposed an integrative model in which shared mental models (SMMs) are theorized as a mechanism to leverage INN in highly multidisciplinary teams. In addition, we claim that transformational leadership (TL), which is usually regarded as a factor contributing to team effectiveness, will attenuate the effect of teams’ PH on team SMM. In a field study of 55 R&D teams in Israel, we found that SMMs mediated the relationship between PH and INN, and that TL moderated the relationship between PH and Team SMM. We discuss the theoretical and practical implication of these findings. 相似文献

Suicide remains the third leading cause of death among young people in the United States. Considering that youth who contemplate suicide generally exhibit warning signs before engaging in lethal self-harm, school-based mental health professionals can play a vital role in identifying students who are at risk for suicidal behavior. Nevertheless, the assessment of vulnerable children and adolescents is a challenging undertaking, with many variables considered relevant to the determination of a student's suicide risk level. This article introduces school-based mental health professionals to the Student Suicide Risk Assessment Protocol, an evaluation tool developed by the author to aid in the determination of student suicide potential, assist with the selection of appropriate interventions, and allow for documentation of school personnel's actions taken to mitigate a student's suicide risk. 相似文献

Almost two-thirds of African American births are to unmarried mothers, and these single parents are among the most economically vulnerable in the United States. The effects of chronic stressors such as poverty can compromise the ability of these mothers to parent effectively, particularly during the developmental period of adolescence, typically a stressful phase of parenting. This article describes a multidimensional family therapy (MDFT) approach to working with African American adolescents who have drug and/or behavior problems. It is maintained that addressing the intrapersonal functioning of African American single mothers is vital if they are to re-establish the attachment bonds necessary for the maintenance of essential parental influence in the lives of their adolescents. Through systematic attention to the parent as an individual, leading to a balance between self-care and care for others, parental supervision is more easily achieved and relational impasses between parent and adolescent more equitably resolved. 相似文献
