元记忆监测与人格特征相互关系的实验研究

运用ＲＪＲ标准程序,考察了元记忆监测与两种人格维度（内外向以及情绪性）的关系,结果表明：元记忆监测水平受到了人格自身优势倾向性及其行为定向性的影响,人格的内外向特点和情绪稳定性特点直接制约着元记忆监测的准确性和稳定性。据此认为元记忆能力的度量和开发,应充分考虑人格因素的影响。     

连绵词语音类似的启动效应

研究采用快速启动范型考察了视觉连绵词加工中语音的自动激活.两个实验发现,无论是首字同音还是尾字同音启动都可以促进对连绵词的命名反应,且基本不受目标词熟悉性(词频高低)及真假词的影响.可以推断,至少在连绵词--这种单词素词的词汇通达中存在语音的自动激活,这种语音的激活可以说是前词的装配与词水平上的改变.     

序列位置内隐学习产生机制的实验研究

内隐学习是当今认知和学习领域继内隐记忆之后又一重要的研究课题。该研究利用序列反应时研究程式,通过两个实验,对序列位置内隐学习产生的机制进行了探讨。结果表明：（１）在序列反应时任务程式中,随着反应一刺激间隔的延长,序列位置内隐学习的学习量逐渐减少;（２）异形同模式迁移组和异形异模式迁移组被试间内隐学习量无显著差异,被试未能内隐地习得抽象的序列模式。说明序列位置内隐学习产生的基础是水平联结,在该实验条件下没有发现垂直联结存在的证据。     

The role of TPH2 variant rs4570625 in shaping infant attention to social signals

TPH2, the rate-limiting enzyme in the synthesis of serotonin, has been connected to several psychiatric outcomes. Its allelic variant, rs4570625, has been found to relate to individual differences in cognitive and emotion regulation during infancy with T-carriers of rs4570625 showing a relatively heightened attention bias for fearful faces. A significant gene-environment interaction was also reported with the T-carriers of mothers with depressive symptoms showing the highest fear bias.We investigated these associations in a sample of 8-month old infants (N = 330), whose mothers were prescreened for low/high levels of prenatal depressive and/or anxiety symptoms. Attention disengagement from emotional faces (neutral, happy, fearful, and phase-scrambled control faces) to distractors was assessed with eye tracking and an overlap paradigm. Maternal depressive symptoms were assessed at several time points during pregnancy and postpartum. The mean levels of symptoms at six months postpartum and the trajectories of symptoms from early pregnancy until six months postpartum were used in the analyses (N = 274).No main effect of the rs4570625 genotype on attention disengagement was found. The difference in fear bias between the genotypes was significant but in an opposite direction compared to a previous study. The results regarding the interaction of the genotype and maternal depression were not in accordance with the previous studies.These results show inconsistencies in the effects of the rs4570625 genotype on attention biases in separate samples of infants from the same population with only slight differences in age.     

注意线索对自闭特质个体疼痛共情的影响：来自事件相关电位的证据

自闭特质个体在日常生活中表现出共情缺损, 但其程度较自闭症谱系障碍个体低, 并且注意线索和特异性的面孔加工可能会影响他们的共情加工进程。因此, 本研究采用事件相关电位(ERP)技术, 以疼痛面孔图片作为刺激材料, 让自闭特质组和控制组分别完成疼痛判断任务(该任务中被试的注意指向疼痛线索)和吸引力判断任务(该任务中被试的注意不指向疼痛线索)。结果发现, 相比控制组, 自闭特质组在吸引力判断任务中疼痛面孔图片诱发的P3波幅更大, 而在疼痛判断任务中两组没有显著差异。这表明注意线索会影响自闭特质个体对他人疼痛面孔的共情反应, 当自闭特质个体不注意他人面孔的疼痛线索时, 其疼痛共情能力会减弱。     

老年人声音诱发闪光错觉的大脑静息态低频振幅

声音诱发闪光错觉(sound-induced flash illusion, SiFI)是一种听觉占主导性的多感觉整合现象, 即当视觉闪光伴随不相等数量的听觉声音在100 ms内相继或同时呈现时, 个体会错觉性地知觉到视觉闪光的个数与听觉声音的数量相等。本研究分别将老年人群体和年轻人群体的声音诱发闪光错觉量(裂变错觉和融合错觉)与全脑的静息态低频振幅(amplitude of low-frequency fluctuation, ALFF)进行相关分析, 考察老年人群体声音诱发闪光错觉效应与大脑静息状态自发活动区域的关系。结果发现, 无论是裂变错觉还是融合错觉, 老年人声音诱发闪光错觉均增大。对于裂变错觉, 老年人的错觉量与内侧前额叶皮层的自发活动呈显著正相关; 对于融合错觉, 老年人的错觉量与额下回、额中回和颞下回的自发活动呈显著正相关, 与枕上回和舌回的自发活动呈现显著的负相关。结果表明, 老年人声音诱发闪光错觉量增大的原因与大脑中多个脑区的静息态自发活动存在关系。     

Whose reading matters? Rereading Exodus 1 in the context of African (South African) women

The narrative of the interaction of African (South African) women and the Bible is first situated within the framework of the folktale of the Lion and the Rabbit. The theme of the multiplication of (male) babies as featured in Exodus 1 is then re-read through the hermeneutical lenses of African (South African) women's experiences. If Exodus 1 is read in family-oriented cultures like that of ancient Israel and Africa, what insights may be gleaned? Which reading(s) may emerge? Will the resultant readings matter especially to African (South) African women? The preceding questions, will be engaged with in this essay.     

Adolescent Gender and Age Differences in Responsiveness to Functional Family Therapy

The current study contributes to a sparse literature on moderators of Functional Family Therapy (FFT) by examining whether responsiveness to FFT, measured by a broad range of outcomes, varies by adolescent gender, age, and their interaction. This study was informed by 687 families (n, adolescents = 581; n, caregivers = 933) and utilized a pre–post comparison design. Fixed-effects regressions with gender, age, and their interaction included as explanatory variables were conducted to calculate the average change in youth mental health, callous–unemotional traits, academic outcomes, substance use, and family functioning. Moderation analyses revealed that according to parent report, girls had significantly greater improvements in peer problems and family functioning, and boys benefited more in increased liking of school. There were differential effects by age, such that older youth had less beneficial mental health outcomes and a smaller decrease in frequency of hash use. The gender by age interaction was significant for adolescents’ report of mental health and family functioning outcomes, which suggests that girls benefit from FFT less than boys during early adolescence, but benefit more than boys in late adolescence. This finding adds to literature which has evidenced that family functioning is particularly important for girls by suggesting that FFT is important for improving older girls’ mental health and family functioning in particular. The study’s results expand the examination of outcomes of FFT to include academic outcomes, and provide insight into key factors that should be considered in addressing adolescent behavioral problems and family functioning.
