运用元分析法整合探究拒绝敏感性与边缘型人格特征关联的已有实证研究, 旨在分析两者间的关联, 并同时考察可能影响该关联的其他变量。经过文献检索和筛选, 共纳入符合要求的原始文献50篇, 含84个效应量, 总样本量为7400人。同质性检验结果表明, 纳入研究的异质性较高, 故进一步对各影响因素变量进行了亚样本及元回归分析。结果发现, 在不同研究设计类型、被试所处地、样本类型、边缘型人格特征指标、拒绝敏感性测量类型的亚样本下, 二者之间的关联存在一定差异, 其中在横向设计、其他地区样本、混合被试、整体边缘型人格特征、量表法测量时所得的拒绝敏感性与边缘型人格特征间的关联最强; 年龄与女性被试比例对该关联不存在显著影响。未来研究可通过纵向研究进一步揭示二者间的预测方向, 考察拒绝敏感性不同成分与边缘型人格特征间的关联, 并在国内开展探索二者关联的研究。  相似文献

采用问卷法对462名初中生进行调查,考察了初中生学业自我效能感在感知校园氛围与网络游戏成瘾(Internet gaming disorder, IGD)关系间的中介效应,以及父母学业卷入对这一中介过程的调节效应。结果发现:(1)在控制了性别、年龄、家庭月收入和父母受教育水平后,感知校园氛围显著负向预测初中生IGD;(2)学业自我效能感在感知校园氛围与IGD关系间起着显著的部分中介效应;(3)父母学业卷入对中介路径\"感知校园氛围→学业自我效能感→IGD\"具有显著的调节效应,即相对于父母学业卷入水平低的初中生而言,这一间接效应对于父母学业卷入水平高的初中生更强。实践干预时,可以通过提高青少年的学业自我效能感和/或调整父母学业卷入程度来预防和控制青少年IGD。  相似文献

The effect of normal aging on lexical production and semantic processing was evaluated in 72 healthy participants. Four tasks were used, picture naming (PN), picture categorization (PC), numerical judgment (NJ), and color judgment (CJ). The dependence of reaction time (RT) and correct responses with age was accounted by mixed-effects models. Participants underwent neuropsychological testing for verbal, executive, and memory functions. The RTs increase significantly with age for all tasks. After parceling out the non-specific cognitive decline, as reflected by the NJ task, the RT for the PN task decreases with age. Behavioral data were interpreted in relation with neuropsychological scores. Our results suggest that (a) naming becomes more automatic and semantic processing slightly more difficult with age, and (b) a non-specific general slowdown of cognitive processing occurs with age. Lexical production remained unaltered, based on compensatory automatic processes. This study also suggests a possible slowdown of semantic processing, even in normal aging.  相似文献

本研究以491名男大学生为被试,考察了沉浸对网络游戏成瘾的影响、沉浸的前因变量和相关作用机制。结果发现:(1)网络游戏中的沉浸与网络游戏成瘾呈显著正相关,与控制、挑战呈显著正相关;挑战和控制与网络游戏成瘾呈显著正相关。(2)挑战通过沉浸的完全中介作用对网络游戏成瘾产生影响,挑战对网络游戏成瘾没有直接效应;控制除了通过沉浸的部分中介作用对网络游戏成瘾产生影响,还对网络游戏成瘾有直接效应。  相似文献

采用眼动记录技术探讨音乐对阅读即时加工过程的影响.考查先导音乐、背景音乐与无音乐条件之间的差异.结果发现:(1)先导音乐比无音乐条件促进了阅读效率的提高,先导音乐改变了被试阅读过程中的眼动模式,瞳孔直径缩小,注视次数减少;(2)与无音乐条件相比,背景音乐对被试的阅读过程起了干扰作用,背景音乐对被试眼动模式的改变体现在瞳孔直径增大,眼跳距离缩小.由此可知,音乐影响阅读过程和阅读结果.先导音乐有助于阅读效果的提高,背景音乐对阅读起干扰作用,音乐对阅读的作用在阅读过程和阅读结果上都有体现.  相似文献

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L1 regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.  相似文献

Prior research has demonstrated the reliability and validity of the Neurological Predictor Scale (NPS) in relation to childhood brain tumor survivor outcomes; however, its use has not been examined in adult long-term survivors. The current study examines the concurrent validity of the NPS with long-term intellectual and adaptive outcomes in adult survivors of childhood brain tumors relative to individual variables alone. A total of 68 adult survivors of childhood brain tumors (M = 24 years old, SD = 4) almost 16 years post diagnosis (SD = 6) completed intellectual evaluations using the Wechsler Abbreviated Scale of Intelligence (WASI). Survivors’ adaptive functioning skills were assessed via informant structured clinical interviews (SIB-R). NPS scores were computed from data acquired from medical records. The NPS was significantly associated with intellectual (R2 = 0.208, p < .05) and adaptive outcomes (R2 = 0.30, p < .05) over and above individual risk factors. Approximately 18% of long-term survivors were identified as impaired in intellectual outcomes, and 29% were identified as impaired in adaptive functioning in everyday life skills. The NPS quantifies the cumulative effects of treatment and neurological sequelae experienced by both short- and long-term survivors of childhood brain tumors. It is a useful and easy measure to employ in clinical research that focuses on quantifying the neurological risk factors associated with long-term intellectual and adaptive functioning outcomes in adult survivors of childhood brain tumors.  相似文献
