情绪信息与注意偏向

情绪信息对注意的调节是情绪研究的热点问题之一。过去的研究多集中于注意偏向,研究范式的多样化、被试群体特质的差异性,导致对注意偏向机制的诸多争论,形成了注意成分说、图式说、注意资源说和PDP模型。注意成分说认为,威胁相关的刺激损害了注意解除能力而引起偏向。图式说认为,图式或知识结构的激活引发注意偏向。注意资源说认为,过多注意资源的消耗引起情绪Stroop实验中的注意偏向。PDP模型认为,特殊人群过高的输入单元激活水平引起注意偏向。     

启动任务中语言经验对藏-汉双语者主导语的影响

采用语义启动任务及藏语与汉语语义相关词和无关词对,探究语言经验能否改变熟练藏-汉双语者的母语主导优势和双语语义表征方式。结果表明,1)无论启动词为藏语还是汉语,藏-汉双语者对汉语L2目标词的加工速度和正确率均显著好于藏语L1,存在语义启动效应; 而在藏语目标词条件下则未发现显著的语义启动效应; 2)藏语到汉语的语义启动效应大于汉语到藏语的启动效应。结果表明,藏-汉双语者的汉语经验对藏语词的表征有影响,但汉语还不能完全替代母语藏语为主导语,结果在一定程度上支持Kroll的RHM模型和Green的ICM模型。

Maternal Life Stress and Subsequent Chinese Toddlers’ Social Adjustment: The Moderating Role of Inhibitory Control

The current study examined the links between maternal life stress and subsequent toddler behavior problems and social competence, as well as the potential moderating effects of cool and hot inhibitory control (IC) in mainland China. Participants included 89 mothers and their infants (42 boys, 47 girls). Mothers completed self-report measure of maternal life stress when their children were 1 year of age (M?=?1.18, SD?=?.07 at Time 1), and reported on their children’s social adjustment using the Chinese version of Infant-Toddler Social and Emotional Assessment (CITSEA) at Time 1 and again a year later (M?=?2.06, SD?=?.09 at Time 2). Toddler IC was assessed with laboratory tasks at Time 2. Structural equation modeling with a bootstrap resample of 1000 indicated that cool IC significantly moderated the longitudinal association between maternal life stress (T1) and latent construct of toddler behavior problems (T2), controlling for behavior problems at Time 1, child age and maternal age. Specifically, maternal life stress was associated with subsequent behavior problems only for toddlers who were low in cool IC. In comparison to the results of behavior problems, high levels of maternal life stress predicted subsequent low levels of social competence. Neither cool IC nor hot IC served as the moderator in the association between maternal life stress (T1) and toddler social competence (T2). These findings indicated that toddler cool IC may promote resilient adaptation and modify the links between maternal life stress and toddler behavior problems but not social competence.     

Coping,social support,stigma, and gender difference among people living with HIV in Guangxi,China

The current study examined whether gender, HIV-related stigma, social support, and the interaction between gender and social support are associated with coping responses among people living with HIV and AIDS (PLWHA) in Guangxi, China. A total of 2987 PLWHA in Guangxi participated from October 2012 to August 2013. Multivariate analysis of covariance was conducted with gender and social support as main factors in the model, and stigma and other variables as covariates. After controlling for demographic variables and stigma, there were significant main effects of emotional social support (F = 1.61, p < .001), functional social support (F = 1.67, p < .001), and informational social support (F = 3.67, p < .001) on various coping strategies. The interaction between gender and informational social support (F = 1.33, p < .05), internalized stigma (F = 37.03, p < .001) and perceived stigma (F = 9.16, p < .001) were associated with various coping strategies. Findings signify the importance of HIV-related stigma and social support differences in the coping strategies among PLWHA in Guangxi, China.     

Rheumatoid arthritis is associated with negatively variable impacts on domains of female sexual function: evidence from a systematic review and meta-analysis

To systematically review the literature to identify the impact of rheumatoid arthritis (RA) on specific female sexual function domains. A meta-analysis was performed and the related literature were searched in MEDLINE, EMBASE, Cochrane Library, CNKI, CBM and Web of Science databases, and in reference lists of articles and systematic reviews. Score of the Female Sexual Function Index (FSFI) was used as the outcome measurement, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Five studies were included, including 346 women with RA and 237 healthy female controls. Each domain of the FSFI score: lubrication (MD, ?2.48; 95% CI, ?3.69, ?1.28), orgasm-1.71 (?2.09, ?1.33), sexual desire-1.27 (?1.59, ?0.95), satisfaction-1.67 (?2.18, ?1.16), arousal-1.83 (?2.85, ?0.82), pain-1.57 (?2.43, ?0.70) and the total score ?8.84 (?11.88, ?5.79) were lower in RA women than healthy controls. Furthermore, lubrication dimension was most severely affected especially. This meta-analysis showed that female RA patients scored lower in each dimension of FSFI, mostly in the lubrication domain. It demonstrated that targeted interventions should be done to improve their sexual function. Future well-designed researches with larger sample sizes are necessary to evaluate the potential risk factors which determine female sexual dysfunction.     

Vocabulary growth rate from preschool to school‐age years is reflected in the connectivity of the arcuate fasciculus in 14‐year‐old children

The acquisition of language involves the functional specialization of several cortical regions. Connectivity between these brain regions may also change with the development of language. Various studies have demonstrated that the arcuate fasciculus was essential for language function. Vocabulary learning is one of the most important skills in language acquisition. In the present longitudinal study, we explored the influence of vocabulary development on the anatomical properties of the arcuate fasciculus. Seventy‐nine Chinese children participated in this study. Between age 4 and age 10, they were administered the same vocabulary task repeatedly. Following a previous study, children's vocabulary developmental trajectories were clustered into three subgroups (consistently good, catch‐up, consistently poor). At age 14, diffusion tensor imaging data were collected. Using ROI‐based tractography, the anterior, posterior and direct segments of the bilateral arcuate fasciculus were delineated in each child's native space. Group comparisons showed a significantly reduced fractional anisotropy in the left arcuate fasciculus of children in the consistently poor group, in particular in the posterior and direct segments of the arcuate fasciculus. No group differences were observed in the right hemisphere, nor in the left anterior segment. Further regression analyses showed that the rate of vocabulary development, rather than the initial vocabulary size, was a specific predictor of the left arcuate fasciculus connectivity.
