隔代抚养与老年人抑郁水平：一项基于东西方文化背景的元分析

通过对横截面研究和病例对照研究进行meta分析探讨隔代抚养与老年人抑郁水平的关系。在三个英文数据库Web of Science、EBSCO和PubMed以及两个中文数据库CNKI和万方检索2021年6月29日前发表的横截面研究以及病例对照研究, 共纳入原始文献22篇。采用随机效应模型估计总体标准均值差(d)和95%置信区间, 东西方文化背景下d值分别为-0.05 (95% CI为[-0.18, 0.08])和0.22 (95% CI为[0.04, 0.40])。此外, 在东方文化背景下, 抑郁测量工具的类型、研究设计类型、性别和配偶状况, 能够显著调节两者的关系; 而在西方文化背景下, 只有抑郁测量工具的类型和研究设计类型能够显著调节两者的关系。在东方文化背景下, 隔代抚养对老年人抑郁水平没有显著作用; 在西方文化背景下, 隔代抚养对老年人抑郁水平起显著的消极作用。     

低社会经济地位影响自我调节的神经机制

自我调节是个体为了实现目标并适应不断变化的环境而监控和调节自己的认知、情绪和行为的能力, 在成就、人际交往和健康等各个领域发挥着作用, 被视为是人类成功和幸福的关键。然而, 大量研究发现个体的社会经济地位越低, 自我调节能力越差。为了提高低社会经济地位者的自我调节能力, 必须深入考察低社会经济地位影响自我调节的机制。神经科学为此提供了独特而重要的信息：低社会经济地位改变了背外侧前额叶皮层、扣带回、腹内侧前额叶、杏仁核、海马体、腹侧纹状体的结构和功能, 进而影响了自我调节的各个成分(认知调节、情绪调节、行为调节)。未来研究除了对神经机制中每条因果链进行更严格地考察外, 还应将神经生物学与发展心理学联系起来深入揭示不同发展阶段低社会经济地位对自我调节的独特影响机制, 并关注低社会经济地位者在神经和行为层面特定反应的适应性, 在此基础上开发出系统、持续、有效的干预方案。     

性激素对人类择偶偏好的影响

择偶是一种重要的心理、社会和文化现象,婚恋择偶除了会受当下社会文化习俗等人文因素的影响,也受到个体生理机制的影响。本文聚焦热点,从进化心理学的角度阐述性激素对人类择偶偏好的影响。女性的择偶偏好受生理周期激素变化的影响,男性的择偶则会因为体内睾酮含量的不同而发生变化。性激素不仅影响人的心理和行为,还会影响人类择偶决策的神经机制。未来的相关研究应关注生理周期的测定方法、被试的文化背景和个体间的差异等。     

国内追踪数据分析方法研究与模型发展

追踪研究因其可以得到比横断研究更有说服力的变量关系论证, 在心理学等科学中具有重要地位。梳理国内以心理学为主的相关领域中追踪数据分析方法研究的发表现状、主要解决的研究问题和模型发展。追踪研究可以进行均值差异比较、分析多变量相互影响、描述总体发展趋势及差异和探究心理动态变化过程。近20年的研究热点和发展思路也集中在上述研究问题当中, 特别是总体发展趋势及差异、多变量相互影响、总体发展趋势与多变量相互影响的融合、追踪研究设计、缺失数据等议题上。最后, 比较国内外研究的差异, 并结合交叉学科对国内追踪研究未来发展做出展望。     

教师的语言形式对儿童语言理解的影响

为考察教师的不同语言形式对儿童语言理解的影响,采用独白、半对话和全对话三种语言形式材料,要求不同年级儿童在不同的语言形式条件下完成七巧板图形的识别任务。结果显示,一年级儿童在全对话和半对话语言条件下的正确识别率均显著高于独白语言条件;三年级儿童在全对话语言条件下的正确识别率显著高于独白语言条件;五年级儿童在全对话语言条件下的正确识别率显著高于独白和半对话语言条件。结果说明,在不同年级儿童中,教师的对话语言以不同的内在过程影响儿童的语言理解,这为了解“对话语言易于理解”的发展性机制提供了依据。     

The Interaction Between Peer Social Support and Stressors Predicts Somatic and Psychological Depressive Symptoms in Chinese Adolescents

Applied Research in Quality of Life - The major goal of this study was to investigate the diathesis-stress model in predicting depressive symptoms in Chinese high school students. A total of 613...     

Gain or non‐loss: The message matching effect of regulatory focus on moral judgements of other‐orientation lies

Previous studies found that individuals with promotion focus are more likely to be persuaded by messages framed in terms of gain‐related words; individuals with prevention focus are more likely to be persuaded by messages framed in terms of loss‐related words. This is known as the message matching effect of regulatory focus. The present study extended this effect into the field of moral judgement of other‐orientation lies. Two experiments were conducted, revealing that (a) individuals with promotion focus judged gain‐framed other‐orientation lies to be more moral, while individuals with prevention focus judged non‐loss‐framed other‐orientation lies to be more moral; and (b) the subjective processing fluency had a partial mediating role in the message matching effect. Theoretical implications and future research directions were discussed.     

Word segmentation by alternating colors facilitates eye guidance in Chinese reading

During sentence reading, low spatial frequency information afforded by spaces between words is the primary factor for eye guidance in spaced writing systems, whereas saccade generation for unspaced writing systems is less clear and under debate. In the present study, we investigated whether word-boundary information, provided by alternating colors (consistent or inconsistent with word-boundary information) influences saccade-target selection in Chinese. In Experiment 1, as compared to a baseline (i.e., uniform color) condition, word segmentation with alternating color shifted fixation location towards the center of words. In contrast, incorrect word segmentation shifted fixation location towards the beginning of words. In Experiment 2, we used a gaze-contingent paradigm to restrict the color manipulation only to the upcoming parafoveal words and replicated the results, including fixation location effects, as observed in Experiment 1. These results indicate that Chinese readers are capable of making use of parafoveal word-boundary knowledge for saccade generation, even if such information is unfamiliar to them. The present study provides novel support for the hypothesis that word segmentation is involved in the decision about where to fixate next during Chinese reading.     

Online Module for Carrier Screening in Ashkenazi Jewish Individuals Compared with In-Person Genetics Education: A Randomized Controlled Trial

To increase accessibility to genetics services for low-urgency patients seeking Ashkenazi Jewish (AJ) carrier screening, we designed an interactive computer (IC) module that provides pre-test genetics education and allows genetics professionals to order the test without meeting the patients beforehand. We compared this module with in-person genetic counseling (GC) using a randomized trial. AJ individuals were randomized to undergo genetics education via the IC module (n = 26) or GC (n = 28). We compared post-interventional genetics knowledge, perceived genetic risk, and anxiety between the two groups, after accounting for pre-interventional scores, using ANCOVA. Wilcoxon Rank-Sum test was used to compare post-interventional satisfaction. Post-interventional genetics knowledge, risk perception, or anxiety were not significantly different between the two groups after accounting for baseline scores (p = 0.50–0.54), although the data are inconclusive regarding the module’s non-inferiority at a 5% margin. Post-intervention satisfaction scores were generally higher in the GC group than the IC module group. Our IC module has the potential to improve access to clinical genetics services for patients and staff, but it is not suitable for all AJ patients and cannot completely replace the benefits of in-person consultations.     

Quantity discrimination in fish species: fish use non-numerical continuous quantity traits to select shoals

Fish typically prefer to live in big shoals due to the associated ecological benefits. Shoaling is a behavior that depends on the ability to quantitatively discriminate. The fundamental mechanism involved in quantity discrimination determines whether fish can discriminate a shoal using numerical discrete cues (e.g., number of shoal members), non-numerical continuous traits (e.g., total body surface area) or both; however, the mechanism is currently a controversial topic. In the present study, we used a spontaneous choice experiment to test whether guppy (Poecilia reticulata), zebrafish (Danio rerio), Chinese crucian carp (Carassius auratus) and qingbo (Spinibarbus sinensis) rely on continuous (i.e., body surface area) or discrete (i.e., number of shoal members) information for shoal selection by altering the body surface area (cumulative body surface area ratio of 3:2 or 1:1) between two stimulus shoals with a different number of members (2 individuals vs 3 individuals). All four fish species preferred to shoal with the stimulus shoal with the larger cumulative surface area even if the shoal had fewer members; however, fish showed no shoal preference when the cumulative surface body areas of both stimulus shoals were equal. Furthermore, qingbo did not numerically discriminate between a shoal with 1 individual and a shoal with 3 individuals when the cumulative surface areas of both stimulus shoals were equal; however, qingbo showed a preference for the shoal with the larger cumulative surface area when the two stimulus shoals each had 3 individuals. In conclusion, the present study demonstrated that all four fish species relied only on non-numerical continuous quantity information for shoal selection, at least under a difficult task (i.e., 2 vs 3).
