行为遗传学是试图定位与行为特性有关的特殊基因或基因组及了解基因与环境之间复杂关系的一种研究.行为遗传学是研究正常范围内的非病理变化,与人类疾病遗传学存在差异.行为遗传学研究面临许多伦理学问题,诸如,智力的遗传性,基因能否决定一切,生物社会学与人类文化评估,生命伦理学与行为遗传学的关系等,因此,对行为遗传学研究结果的阐述必须十分谨慎. 相似文献

Schizophrenia has been associated with deficits in functional brain lateralization. According to some authors, the reduction of asymmetry could even promote this psychosis. At the same time, schizophrenia is accompanied by a high prevalence of nicotine dependency compared to any other population. This association is very interesting, because sex-dependent effects of smoking in auditory language asymmetries have been reported recently, and the verbal domain is also one major focus in cognitive deficit studies of schizophrenia. Thus, the altered laterality pattern in schizophrenia could, at least in part, result from secondary artefacts due to smoking rather than being a pure cause of the disease itself. To test this hypothesis, the present study examined auditory language lateralization in 67 schizophrenia patients and in 72 healthy controls in a phonemic and an emotional dichotic listening task. Our findings replicate previous research, in that smoking reduces language lateralization in men in phonemic dichotic listening. In addition, we show that smoking also reduces laterality in women in the emotional dichotic listening task. Thus, smoking alters phonemic and emotional language asymmetries differentially for men and women, with a stronger effect for men in the left hemisphere phonemic task, and a stronger effect for women in the right hemisphere emotional task. Together, these findings point towards an effect of smoking which is possibly independent of sex and hemisphere. Importantly, by testing equal numbers of smoking and non-smoking patients and controls, we found no schizophrenia-associated asymmetry effect. Possible neurobiological mechanisms with which smoking may alter auditory microcircuits and thereby diminish left-right differences are discussed. 相似文献

We here report two studies exploring associations between inhibitory control (measured with the Sustained Attention to Response Task, SART) on the one hand, and self-reports of trait cooperativeness and empathy on the other. A coherent picture was obtained in women whose inhibitory control proficiency predicted higher scores on the Temperament and Character Inventory Cooperativeness and a higher Empathy Quotient. Individual differences in working memory did not predict self-reported empathy. In men, the association between SART performance and empathy was less clear: Good performance on the inhibitory task predicted lower scores on Cooperativeness and was unrelated to the Empathy Quotient. In both studies, women outperformed men on the SART. The results in women may reflect how individual differences in elemental neuro-cognitive operations such as inhibitory control influence more complex functions such as social cognition. 相似文献

通货膨胀首先是货币现象,预示着投入流通的货币量太多。但是在中西方经济学界,却将通货膨胀等同于物价上涨、通货膨胀率等同于物价上涨率。笔者以为这是一种似是而非的认识。通货膨胀与物价上涨既有联系又有区别,治理通货膨胀与控制物价上涨需要采取基本不同的手段。 相似文献

This study examined the influence of gender, socioeconomic status, and race/ethnicity on the career aspirations of over 22,000 8th and 10th grade youth. The top five occupations identified by youth as aspirations included artist, lawyer, musician, FBI agent, and actor/actress. Top occupations were also reported for each gender × socioeconomic status × race/ethnicity group. Aspirations were coded by social prestige level, minimum education requirements, and median salary. Results revealed significant main effects for socioeconomic status and race/ethnicity as well as significant interaction effects. Further, significant gender main effects and a significant gender × ethnicity interaction were found for occupational prestige and educational requirements. 相似文献

有调节的中介模型是中介过程受到调节变量影响的模型。评介了基于Bootstrap不对称置信区间和贝叶斯不对称可靠区间进行有调节的中介模型检验的3种方法, 包括亚组分析法、差异分析法和系数乘积法。模拟研究发现, 偏差校正的百分位Bootstrap置信区间和无先验信息的贝叶斯可靠区间在有调节的中介模型检验中表现相当, 都优于百分位Bootstrap置信区间的表现。建议使用系数乘积法进行第一阶段或第二阶段被调节的中介模型检验, 使用差异分析法进行两阶段被调节的中介模型检验, 并用一个实际例子演示如何用不对称区间估计检验有调节的中介模型。随后评述了3种有调节的中介模型检验方法在国内心理学的应用现状, 并展望了检验的拓展方向。 相似文献

Beck抑郁认知理论认为功能失调性态度和自动思维对抑郁的形成和发展有着重要的影响, 但是不同水平的认知因素在青少年抑郁中起什么样的作用还有待于进一步的研究。根据Oei和Kwon (2007)综合认知模型(ICM), 我们假设在青少年负性生活事件和抑郁症状间功能失调性态度是调节变量, 而自动思维是中介变量。研究采用开学初和临近期末间隔近四个月两个时间点的纵向数据搜集方式, 对613名初中生施以青少年生活事件量表(ASLEC)、功能失调性态度问卷(DAS)、自动思维问卷(ATQ)以及流调中心用抑郁量表(CES-D), 然后通过路径分析对模型进行了拟合度和性别差异检验, 结果表明:(1)各变量显著相关(p<0.01), 且各变量间隔四个月两个时间点的分数差异显著(p<0.01); (2)修正后的青少年抑郁综合认知模型较好地拟了数据, 且功能失调性态度与负性生活事件的交互作用对自动思维的影响上女生的路径系数显著大于男生。结论:功能失调性态度在负性生活事件和青少年抑郁症状间起调节作用, 而自动思维从中起到了认知中介的作用, 且该模型性别差异显著。 相似文献

二次响应面回归分析是指二次多项式回归与响应面分析相结合的一种研究方法, 该方法在工业与组织心理学领域起源于个体8722;环境(P-E)匹配研究。它使用对个体8722;环境进行间接匹配测量的策略, 考察二者间的最佳匹配以及与结果变量的复杂关系, 并在三维空间对其进行检验和解释。该文在分析以往P-E匹配研究方法(例如差异分数)缺陷性的基础上, 阐述了二次响应面回归方法的产生与发展, 逻辑思想, 统计分析方法, 并以实例演示其操作步骤与结果解释, 以及相对于其他方法的优势与不足。 相似文献
