统计学习与双语认知的关系

统计学习是提取环境输入潜在规则的一种认知机制,其与语言的关联已得到证实。双语认知是学界关注的热点之一。统计学习与双语认知的关系如何?文章先介绍统计学习认知机制及其与语言的关系,然后从“统计学习能力可否预测二语学习表现”、“统计学习训练能否促进二语学习”和“双语经验能否提高统计学习能力”三个维度述评相关文献,并指出未来可从输入特征、个体差异和神经科学角度进一步探讨统计学习与双语认知的关系。

青少年时间态度与学业拖延的关系：成就动机的中介作用

采用青少年时间态度量表、成就动机量表和学业拖延问卷,对 733名中学生进行调查,旨在探究时间态度与学业拖延的关系,揭示成就动机在时间态度与学业拖延之间的中介作用机制。结果发现（1）过去消极、现在消极和未来消极与学业拖延呈显著正相关,过去积极、现在积极和未来积极与学业拖延呈显著负相关。（2）过去消极、现在消极和未来消极与成就动机呈显著负相关,过去积极、现在积极和未来积极与成就动机呈显著正相关;成就动机与学业拖延呈显著负相关。（3）成就动机在现在消极与学业拖延之间起部分中介作用,在未来积极、未来消极与学业拖延之间起完全中介作用。

Effects of Father-Adolescent and Mother-Adolescent Relationships on Depressive Symptoms among Chinese Early Adolescents

Parent–adolescent relationships play an important role in protecting adolescents from depressive symptoms. However, there are no consistent conclusions about the extent to which fathers and mothers uniquely contribute to adolescents’ depressive symptoms. The present study aimed to acquire knowledge in this research area in two ways. First, this study separated the potential impacts of father–child and mother–child relationships on depressive symptoms in Chinese adolescents. Second, this study used a longitudinal design with nationally representative samples from the China Education Panel Survey. A total of 8794 middle school students in grade 7 completed measures of father–adolescent and mother–adolescent relationships, and depressive symptoms twice (T1 and T2; one-year interval). Results indicated that both positive father–adolescent and mother–adolescent relationships had negative effects on depressive symptoms in female adolescents. However, positive father-adolescent, not mother-adolescent, relationships had a negative effect on depressive symptoms in male adolescents. These findings suggest that positive parent–adolescent relationships could reduce early adolescents’ depressive symptoms, but positive father–adolescent and mother–adolescent relationships might have different protective effects on early adolescents’ depressive symptoms among male and female adolescents in China.

     

项目竞争强度对网络成瘾大学生提取诱发遗忘的影响

执行功能缺陷是网络成瘾发生、维持和复发的原因之一,以往研究侧重于探讨网络成瘾者注意控制、反应抑制等执行功能成分的损伤状况,而其记忆抑制状况尚不清楚。本研究通过考察网络成瘾大学生的提取诱发遗忘（RIF）来探讨其记忆抑制的特点及RIF的产生机制。结果发现：低网络成瘾个体在高项目竞争强度下表现出显著的RIF,在低项目竞争强度下未产生;高网络成瘾个体在低项目竞争强度下表现出显著的RIF,在高项目竞争强度下未产生。结果表明网络成瘾大学生的记忆抑制能力受损严重,其在低项目竞争强度下易受相关代价与效益问题（CCB）影响而产生干扰性RIF。     

Parents’ Attachment Styles and Adolescents’ Regulatory Emotional Self-efficacy: The Mediating Role of Adolescents’ Attachment to Parents in China

Guided by attachment theory, this longitudinal study examined the mediating role of parent-adolescent attachment on the relation between parents’ attachment styles and adolescents’ regulatory emotional self-efficacy (RESE, including managing negative affect and expressing positive affect). Five hundred seventy-three Chinese junior high school students (46% male; aged 11–14 years, M = 12.76 years, SD = 0.74) completed measures of RESE at T1, parent-adolescent attachment at T2 (six months later), and RESE at T3 (another six months later), while 573 students’ parents (one student only has a parent, 241 fathers and 332 mothers) completed measures of adult attachment styles (anxiety and avoidance) at T1. Results from structural equation modeling indicated that father-adolescent attachment mediated the association between fathers’ attachment anxiety and adolescents’ self-efficacy beliefs in managing negative affect, while mother-adolescent attachment marginally mediated the relation between mothers’ attachment anxiety and adolescents’ self-efficacy beliefs in managing negative affect and expressing positive affect. These findings suggest that parents’ attachment anxiety could predict their children’s attachment to parents, in turn, impacting their children’s regulatory emotional self-efficacy.

     

Intergenerational Coresidence and Life Satisfaction in Old Age: The Moderating Role of Homeownership

Household structure for older people’s subjective well-being is important to promote healthy ageing in the context of the rapid increase of the older population. Living with adult children is known to promote older people’s life satisfaction, a key indicator of subjective well-being, whereas others claim a negative impact of such intergenerational coresidence. This study aims to empirically test these theories (family support vs. family conflict), by examining the role of homeownership–another important factor contributing to subjective well-being–in this association between intergenerational coresidence and life satisfaction. Analysing the nationally representative data on the elderly population in South Korea, the findings showed that intergenerational coresidence decreases life satisfaction when the elderly achieve a certain level of housing security by living in owner-occupied housing. Living with adult children is negatively associated with life satisfaction particularly for older old homeowners compared to younger old owners. Our findings provide implications for public policies promoting intergenerational coresidence and asset-based welfare to enhance older people’s well-being in Korea and more broadly in East Asia.

     

Sample size determinations for Welch's test in one‐way heteroscedastic ANOVA

For one‐way fixed effects ANOVA, it is well known that the conventional F test of the equality of means is not robust to unequal variances, and numerous methods have been proposed for dealing with heteroscedasticity. On the basis of extensive empirical evidence of Type I error control and power performance, Welch's procedure is frequently recommended as the major alternative to the ANOVA F test under variance heterogeneity. To enhance its practical usefulness, this paper considers an important aspect of Welch's method in determining the sample size necessary to achieve a given power. Simulation studies are conducted to compare two approximate power functions of Welch's test for their accuracy in sample size calculations over a wide variety of model configurations with heteroscedastic structures. The numerical investigations show that Levy's (1978a) approach is clearly more accurate than the formula of Luh and Guo (2011) for the range of model specifications considered here. Accordingly, computer programs are provided to implement the technique recommended by Levy for power calculation and sample size determination within the context of the one‐way heteroscedastic ANOVA model.
