Low frequency Repetitive Transcranial Magnetic Stimulation (rTMS) has previously been applied to language homologues in non-fluent populations of persons with aphasia yielding significant improvements in behavioral language function up to 43 months post stimulation. The present study aimed to investigate the electrophysiological correlates associated with the application of rTMS through measurement of the semantic based N400 Event-related brain potentials (ERP) component. Low frequency (1 Hz) rTMS was applied to the anterior portion of the homologue to Broca’s area (pars triangularis), for 20 min per day for 10 days, using a stereotactic neuronavigational system. Twelve non-fluent persons with aphasia, 2-6 years post stroke were stimulated. Six participants were randomly assigned to receive real stimulation and six participants were randomly assigned to receive a blind sham control condition. ERP measures were recorded at baseline, 1 week and 2 months subsequent to stimulation. The findings demonstrate treatment related changes observed in the stimulation group when compared to the placebo control group at 2 months post stimulation indicating neuromodulation of N400 as a result of rTMS. No treatment related changes were identified in the stimulation group, when compared to the sham group from baseline to 1 week post stimulation. The electrophysiological results represent the capacity of rTMS to modulate neural language networks and measures of lexical-semantic function in participants with non-fluent aphasia and suggest that time may be an important factor in brain reorganization subsequent to rTMS.  相似文献

Appearance is one way in which lesbian and bisexual identities and affiliation to lesbian, gay, bisexual (LGB) subculture can be demonstrated. ‘Butch’ and ‘androgynous’ styles have been used by lesbian women to communicate a non‐heterosexual identity. However, some LGB appearance researchers have argued that there has been a mainstreaming and diversification of lesbian style in the last couple of decades, which has resulted in less distinction between lesbian and straight looks. This research draws on the Social Identity approach to explore contemporary style in lesbian and bisexual communities. Fifteen lesbian and bisexual women took part in semi‐structured interviews which were analysed using thematic analysis. Although some participants reported a diversification of lesbian style, most used the term ‘butch’ to describe lesbian style, and a ‘boyish’ look was viewed as the most common contemporary lesbian style. By contrast, most participants could not identify distinct bisexual appearance norms. The data provide evidence of conflicting desires (and expectations) to visibly project social identity by conforming to specific lesbian styles, and to be an authentic, unique individual by resisting these subcultural styles.

In this article, we generate a concept of Muslim religiosity based on narrations reflecting Muslim women’s everyday lived religion in Austria. Using Grounded Theory, we analysed 30 biographical interviews conducted in 2006 with first-generation female migrants from Turkey and Bosnia-Herzegovina. In agreement with prior studies, we emphasise that Muslim religiosity is multi-dimensional. According to our results, it consists of a belief and a behavioural dimension, with the latter dividing into ‘rituals and duties’ and ‘ethical behavioural principles’. Moreover, we pay close attention to the interrelation between religion and culture—which is particularly relevant in a migration context—and shed light on the functions of religiosity.  相似文献

This study examined the moderating role of emotion recognition on the association between preschoolers’ ADHD behaviors and social functioning outcomes. Sixty preschoolers (48.3% female; Mage?=?3.94, SDage?=?.56) were recruited from Head Start-affiliated classrooms. Teacher-rated ADHD behaviors and an objective measure of children’s emotion recognition were assessed at the beginning of the school year. Teacher ratings of social functioning outcomes were obtained approximately three months after the start of school. Hierarchical regressions examined the unique and interactive effects of ADHD behaviors and emotion recognition on preschoolers’ social functioning outcomes (i.e., oppositional behaviors, peer behavior problems, and social-emotional school readiness). The interaction between ADHD behaviors and emotion recognition predicted oppositional behaviors, peer behavior problems and social-emotional school readiness such that higher levels of emotion recognition appear to buffer the negative association between ADHD behaviors and adaptive social functioning. Preliminary considerations for interventions aimed at promoting preschoolers’ social functioning are discussed.

Experiences of anxiety and depression are common in adults with Cystic Fibrosis (AwCF) (e.g. Quittner in Thorax 69:1090-1097, 2014) and may impact on a wide range of important health-related behaviours, such as adherence to medication and timely attendance for medical review when experiencing pulmonary exacerbation. Common screening measures used in CF such as the PHQ-9 and GAD-7 may reflect an absence of anxiety or depression when clinically significant emotional difficulties are apparent on further assessment. This study preliminarily validated the previously developed Distress in Cystic Fibrosis Scale (DCFS) (Patel in Journal of Cystic Fibrosis 15:S26, 2016); a 23-item questionnaire to assess psychosocial distress in AwCF. Inpatient and outpatient participants with CF (N?=?119) completed a battery of questionnaires, including the DCFS. PCA results supported a single component model. The DCFS showed high internal consistency and correlated significantly with measures of mood and quality of life. The DCFS shows promise as a screening tool to assess clinically significant psychosocial distress in an adult CF population.

Social status is associated with the vertical spatial dimension, with people conceptualizing higher social status with higher vertical positions. Two experiments tested whether this association influences relatively real‐world decisions about others by asking participants to act as real estate agents, aiding in the relocation of clients who explicitly or implicitly varied in social status. Across experiments, higher status clients were placed into higher elevation housing options. This influence of social status persisted when strategy‐aware participants were removed from analysis, and was not influenced by individual differences in social dominance or locus of control. Abstract concepts of social status are understood through associations with vertical space, and these mapping of abstract concepts to concrete percepts prove influential in guiding daily decisions.  相似文献

Objective

To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns.

Method

We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR.

Results

IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2 h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p = .037), and a close to significant one between infants’ lividness at Time 0 and IR (p = .053). The first breath of the 31 newborns occurred before and was not associated with the first cry (p < .001).

Discussion

The main features of IR at birth are similar to those of the universal most severe response to severe stress or danger. The relationship with PS suggests that children who had IR at birth might be at risk for similar disorders as those associated with PS. Sudden neonatal collapse of one of the IR newborns needs further research to determine if they are at risk for sudden infant death syndrome.

Conclusion

This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.  相似文献

Two experiments were conducted to study effects of modality, temporal position, and their interaction on comparisons of successive stimuli. In Experiment 1, intramodal (tone–tone and line–line) and crossmodal (tone–line and line–tone) stimulus pairs, with two interstimulus intervals (ISIs), 400 and 2,000 ms, were presented. Participants indicated which stimulus was the “stronger.” Time-order errors (TOEs) were assessed using the D% measure and were found in all types of pairs. Variation in TOEs across conditions was well accounted for by changes in parameters (stimulus weights, reference levels) in an extended version of Hellström’s sensation weighting (SW) model. With an ISI of 2,000 ms, the first stimulus had a lower weight (less impact on the response) than did the second stimulus. More negative TOEs were found with the longer ISI in all pair types except tone–line. In Experiment 2, participants indicated which of two lines was the longer or which of two tones was the louder. An intra- or crossmodal anchor, or no anchor, was interpolated between the stimuli. Anchoring tended to reduce the weight of the first stimulus, suggesting interference with memory, and to yield negative TOEs. Intramodal anchors yielded reduced weights of both stimuli, most dramatically for tones, suggesting an additional effect of stimulus interference. Response times decreased with crossmodal anchors. For line–line pairs, strong negative TOEs were found. In both experiments, the variation in TOE across conditions was well accounted for by the SW model.  相似文献

The adverse social and physical conditions of homelessness pose significant developmental risks for children, which may be compounded or buffered by the quality of parenting behaviour they are exposed to. There is currently a limited understanding of how parents approach their care-giving role and responsibilities while adjusting to the experience of homelessness. Advancing knowledge in this area is essential for developing acceptable, appropriate and effective interventions to support highly marginalised and vulnerable homeless families. This review explored homeless parents’ perceptions of how homelessness affects their parenting behaviour and identified adaptive strategies that parents may use to mitigate the potentially negative impacts of homelessness on the quality of care-giving. A systematic search of four electronic databases (ASSIA, PsycINFO, Web of Science and MEDLINE) identified 13 published qualitative studies, all originating from the USA, which explored parenting behaviour in homeless contexts. The studies were critically appraised using the CASP qualitative assessment tool. Thematic synthesis identified the following determinants of parenting behaviour; negative self-concept in the parental role, parental mental health, material resources, challenges to autonomy and self-efficacy, daily hassles, physical environment and service context, stigma, child characteristics and lack of support. These were synthesised thematically using existing models of parenting determinants and positive parenting. Findings indicate substantive impacts of homelessness on parental mental health, parenting authority, material resources, parenting environments and social support. Parents developed a number of adaptive methods to negotiate the challenges of homeless parenting such as maintaining a positive mindset, cherishing the parental role and developing practical strategies. We conclude with recommendations that service providers should tailor parenting support to resource-constrained circumstances and that further research is required in order to better understand experiences of homeless parents in other international contexts.  相似文献
