The current longitudinal study is the first comparative investigation across low‐ and middle‐income countries (LMICs) to test the hypothesis that harsher and less affectionate maternal parenting (child age 14 years, on average) statistically mediates the prediction from prior household chaos and neighborhood danger (at 13 years) to subsequent adolescent maladjustment (externalizing, internalizing, and school performance problems at 15 years). The sample included 511 urban families in six LMICs: China, Colombia, Jordan, Kenya, the Philippines, and Thailand. Multigroup structural equation modeling showed consistent associations between chaos, danger, affectionate and harsh parenting, and adolescent adjustment problems. There was some support for the hypothesis, with nearly all countries showing a modest indirect effect of maternal hostility (but not affection) for adolescent externalizing, internalizing, and scholastic problems. Results provide further evidence that chaotic home and dangerous neighborhood environments increase risk for adolescent maladjustment in LMIC contexts, via harsher maternal parenting. 相似文献

摘 要 为探讨网络使用对学业成就的影响及其作用机制,从自我效能感理论的角度使用问卷对425名小学生进行调查。结果表明:(1)网络使用完全通过学习效能感的中介作用正向预测学业成就;(2)学习效能感中介作用受到开放性的调节,即在开放性高的个体中,学习效能感在网络使用与学业成就之间的中介效应不显著;在开放性低的个体中,学习效能在网络使用与学业成就之间有显著的中介效应。研究结果揭示了网络使用对学业成就的影响与作用机制,对家长、教育工作者根据儿童的个人特质对网络使用进行适度引导有启示意义。 相似文献

师徒的相互选择过程是师徒关系研究中的一个重要问题。本文采用三个实验探讨了影响师徒相互选择倾向的个体特征因素。实验一和实验二探讨了徒弟选师傅时,师傅的外向性、成就动机水平、管理职务和性别一致性对徒弟选择师傅倾向的影响。实验三探讨了师傅选择徒弟时,徒弟的外向性、成就动机水平和性别一致性对师傅选择徒弟倾向的影响。实验结果表明在徒弟选择师傅时,师傅的外向性、成就动机、管理职务,是影响因素;在师傅选择徒弟时,徒弟的外向性、成就动机水平是影响因素。 相似文献

Family Resource Allocation after Firstborns Leave Home: Implications for Secondborns' Academic Functioning 下载免费PDF全文
Alexander C. Jensen Shawn D. Whiteman Julia M. Bernard Susan M. McHale 《Family process》2017,56(3):766-780
This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning. 相似文献

Jean Piaget’s (1896–1980) interdisciplinarity was related to his psychology in several ways. First, he was a simple tourist of other fields: an interested outsider. But as he became increasingly involved in the professionalization of the discipline, he moved through different contexts that constrained the possibilities for successful action in new and different ways. To make these clear, we adopt a little-known aspect of his later epistemological framework: the open hierarchy of levels. This then affords new perspectives of his life, his work, his theory and his location in the history of both Swiss psychology and French psychology. It also outlines his reasoning regarding the necessity of a disciplined approach to interdisciplinary collaboration, institutionalized in the founding of his International Centre for Genetic Epistemology. We therefore come not only to a fuller understanding of how Piaget thought scientific knowledge develops, but also of how the boundaries of scientific disciplines are pushed back. 相似文献

How do people stretch their understanding of magnitude from the experiential range to the very large quantities and ranges important in science, geopolitics, and mathematics? This paper empirically evaluates how and whether people make use of numerical categories when estimating relative magnitudes of numbers across many orders of magnitude. We hypothesize that people use scale words—thousand, million, billion—to carve the large number line into categories, stretching linear responses across items within each category. If so, discontinuities in position and response time are expected near the boundaries between categories. In contrast to previous work (Landy, Silbert, & Goldin, 2013) that suggested only that a minority of college undergraduates employed categorical boundaries, we find that discontinuities near category boundaries occur in most or all participants, but that accurate and inaccurate participants respond in opposite ways to category boundaries. Accurate participants highlight contrasts within a category, whereas inaccurate participants adjust their responses toward category centers. 相似文献

Explaining after by before: Basic aspects of a dynamic systems approach to the study of development 总被引:2,自引:0,他引:2
The basic properties of a dynamic systems approach of development are illustrated by contrasting two simple equations. One, yt+1 = f (yt), is characteristic of dynamic systems models. The other, yi = f (xi), refers to what, for the sake of simplicity, is referred to as the standard developmental approach. We give illustrations from cognitive, language and social development to show the characteristic differences of these two types of models and show their complementarity. The article further compares the “Bloomington” with the “Groningen” approach to dynamic systems theorizing in developmental psychology. It continues with a discussion of two important questions. One involves the issue of measurement and the nature of developmental variables from the viewpoint of dynamic systems. The second concerns the question of short- and long-term time scales in developmental models, which is discussed on the basis of an example, namely dyadic interaction of young children in the context of different social statuses. 相似文献

亲子教育缺失与"留守儿童"人格、学绩及行为问题 总被引:100,自引:2,他引:98
以“留守儿童”为被试,考察其家庭环境因素、人格、学绩、行为问题之间的关系,发现“留守儿童”处在相对不良的家庭环境中;不良的家庭环境因素与不良人格特质、行为问题、学业不良高相关,且后三者密切关联,相互加剧。讨论指出:对“留守儿童”问题的干预不仅要进行行为矫治和心理辅导,而且要整合社区、学校、家庭的力量,改善其家庭环境和心理氛围,为“留守儿童”建构有效的支持系统。 相似文献
