Although factors shaping sibling relationships and the developmental dynamics of such consanguinity have been addressed by various scholars, investigations questioning how the risky behaviors of one sibling, specifically substance abuse, may impact brothers versus sisters are few. The current study explored non–substance-abusing siblings’ reports of their mood, attitudes, feelings of social support, and emotions if one of their brothers or sisters was perceived to be a substance abuser. Surprisingly, 22% of a college-aged convenience sample (N = 312) described one or more of their siblings as a substance abuser and reported being exposed to drugs at an earlier age than their non–substance-abusing counterparts, in addition to other differences. Sisters, more than brothers, were also affected. These exploratory findings, although limited by potential sampling bias, highlight potential areas for future research that could clarify and perhaps improve the experience of the “forgotten” siblings in a risky family constellation. 相似文献

差别易感性模型认为,携带某种基因型的个体既容易受到消极环境的不利影响,同时也容易受到积极的、支持性环境的有利影响。随着定量遗传学和分子遗传学技术的不断发展,涌现出关于基因-环境对儿童发展交互作用的大量研究,主要包括5-HTTLPR、DRD4、MAOA、COMT和BDNF五种基因与环境因素(如,母亲敏感性、压力性生活事件和家庭养育环境等)对儿童发展的交互作用,支持了差别易感性模型。但是,关于基因与环境交互作用的机制、携带易感性基因个体的种族和性别差异问题以及优势敏感性假说的验证,都是该领域未来研究的重要方向。 相似文献

为探讨大学生心理需求、认知评估、自我调控和网络社交的关系,采用大学生心理需求量表、网络利弊权衡问卷、自我调控问卷和网络交往问卷对503名大学生进行调查,结果发现:(1)大学生心理需求可显著正向预测网络社交;对上网的好处和代价认知评估在两者间起部分中介作用。(2)自我调控在心理需求和网络社交间起调节作用。由此得出结论,大学生的心理需求可显著影响网络社交,对上网的好处和代价认知评估在二者间起中介作用,自我调控起调节作用。研究结果进一步揭示了心理需求影响网络社交的内在机制,可为网络时代大学生进行健康网络社交提供有益指导。 相似文献

Two experiments were conducted to examine framing effects in sport. In Experiment 1, a conceptual replication [Loftus, E. F., & Palmer, J. C. (1974). Reconstruction of automobile destruction: An example of the interaction between language and memory. Journal of Verbal Learning and Verbal Behavior, 13(5), 585–589], participants watched a hockey collision, with the hit described later in a written format as a “contact”, “bump”, or “smash”. This manipulation resulted in no differences in participants’ report of how fast the players were skating, their intentions, and the outcome of the hit. In Experiment 2, participants watched the same video clip with ongoing commentary. Those who heard the announcer describing the event as “contact” estimated a higher skating speed than participants who were exposed to the “smash” commentary. Participants who were exposed to the “bump” commentary rated the repercussions of the collision as less severe than did those exposed to the other commentaries. These findings show that the perception of magnitude hierarchy may be domain specific and suggest future avenues for exploring framing effects when one is exposed to visual stimuli. 相似文献

Subgroup analyses allow us to examine the influence of a categorical moderator on the effect size in meta‐analysis. We conducted a simulation study using a dichotomous moderator, and compared the impact of pooled versus separate estimates of the residual between‐studies variance on the statistical performance of the Q B (P) and Q B (S) tests for subgroup analyses assuming a mixed‐effects model. Our results suggested that similar performance can be expected as long as there are at least 20 studies and these are approximately balanced across categories. Conversely, when subgroups were unbalanced, the practical consequences of having heterogeneous residual between‐studies variances were more evident, with both tests leading to the wrong statistical conclusion more often than in the conditions with balanced subgroups. A pooled estimate should be preferred for most scenarios, unless the residual between‐studies variances are clearly different and there are enough studies in each category to obtain precise separate estimates. 相似文献
