Aversive conditioning,schizotypy, and affective temperament in the framework of the salience hypothesis

During classic conditioning, the processing of conditioned stimuli (CSs+) is enhanced relative to neutral stimuli (CSs−). In patients with psychotic disorders, CSs− become abnormally relevant relative to CSs+, which may lead to the formation of aberrant associations. In this study, we explored how schizotypal and affective personality traits are associated with salience processing in nonclinical individuals. We used aversive conditioning and personality questionnaires in 100 healthy volunteers. The CSs+ were colored circles predicting the unconditioned stimulus (US), which was a loud noise. Circles of another color were the CSs− predicting no US. Conditioning was measured with skin conductance responses (SCRs) and reaction time. Results revealed that higher reality distortion, introvertive anhedonia, and cyclothymic personality negatively correlated with SCRs and positively correlated with reaction time for CSs+, which indicates less efficient conditioning. After taking into account the covariance between these personality traits, only reality distortion and introvertive anhedonia remained significant for CS+ SCRs, and introvertive anhedonia remained significant for CS+ reaction time. Enhanced responses to CSs− were positively predicted only by reality distortion. These results suggest that salience-processing biases are related to schizotypal personality traits in healthy individuals, exhibiting a similar pattern to that observed in psychotic disorders.     

Warmth and Contingency and Their Relationship to Maternal Attitudes Toward Parenting

In this study, the authors addressed the question of whether maternal parenting behaviors in terms of sensitivity, warmth, and contingency with respect to small infants were equally represented in attitudes toward parenting. Sixty mothers from central Germany with middle-class socioeconomic backgrounds were videotaped with their 1st born 3-month-old infant in a free-play and a caregiving episode in their home. The different maternal parenting components were behaviorally analyzed. Maternal attitudes toward parenting were assessed with self-report measures. The results showed that behavioral sensitivity was significantly associated with attitudes related to contingency, whereas behavioral warmth and contingency were not associated with maternal attitudes. The authors interpreted differential associations as a reflection of intuitive and explicit parenting strategies, with only sensitivity being explicitly represented.     

妊娠晚期亚临床甲状腺功能减退症对母婴合并症的影响

本研究旨在观察妊娠晚期亚临床甲状腺功能减退症对母婴合并症的影响。最终选择2010年1月～2010年11月期间共325例妊娠晚期孕妇分为病例组（A组,n＝65）和正常对照组（B组,n＝260）,观察两组之间母婴合并症的变化。结果显示,两组之间在年龄、住院日、血压、体质量指数（BM I）、心率、分娩时孕周、血糖以及血脂方面差异均无统计学意义（P＞0．05）。但与B组相比较,A组发生母亲合并症及胎儿合并症的发生率明显增加,差异有统计学意义（P＜0．05）。此研究提示妊娠晚期亚临床甲状腺功能减退症增加母婴合并症的风险。

The Relationship between Temperament and Life Satisfaction in Early Adolescence: Cognitive and Behavioral Mediation Models

This study investigated the interrelationships among temperament, social self-efficacy, social competence, and life satisfaction in a sample of 160 early adolescents. A model was proposed based on previous research by Argyle and Lu (1990, Personality and Individual Differences 11, pp. 1255–1261) in which social competence mediates the relationship between temperament (i.e. extraversion and neuroticism) and life satisfaction. However, this study extended the work of Argyle and Lu by including an objective measure of social competence, in addition to a measure of social self-efficacy, to test as a potential mediator between temperament and life satisfaction. Results indicated that social self-efficacy mediated the relationship between extraversion and life satisfaction, but not between neuroticism and life satisfaction. Teacher-rated social competence did not mediate the effects of temperament on life satisfaction. The importance of integrating theories of trait psychology and cognitive psychology in adolescent life satisfaction research is discussed.     

Associations between childhood biomedical factors,maternal smoking,personality traits,Body and Mass Index and the prevalence of asthma in adulthood

Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.     

Like mother,like child? Maternal determinants of children's early social-emotional development

Social-Emotional competencies evolve early in life. For example, early emotion regulation is learned primarily in the context of mother–child interaction, which may allow for maternal influences to shape children's social-emotional development. The aim of the current study was to longitudinally examine maternal determinants of children's early social-emotional development in a community-based sample of first-time mothers (N = 61, aged 22–39 years). Specifically, we used structural equation modeling to examine how maternal emotion regulation difficulties and subclinical depression directly and indirectly, through sensitivity and postnatal bonding, assessed at 6 to 8 months predicted child outcomes at 12 to 16 months. We found that mothers’ sensitivity predicted fewer social-emotional and behavioral problems and that stronger bonding predicted fewer problems and more social-emotional competencies. Emotion regulation difficulties were significantly associated with depressive symptoms; yet, when accounting for shared variances, both factors differentially predicted less positive child outcomes such that more difficulties indirectly, through poorer bonding, predicted greater delay in competencies, and more symptoms indirectly, through less sensitivity, predicted more problems. Current findings underline the significance of maternal factors impacting the quality of mother–child interaction for children's positive development. Potential implications for early prevention programs to support children who are otherwise at risk for negative emotional outcomes due to mothers’ emotional state postpartum are discussed.
