外在特征变化对人像辨认的影响

运用眼动分析法探讨了外在特征变化对人像辨认的影响,即外在特征多少、学习与辨认外在特征的一致性对人像辨认的影响。因变量为人像辨认的反应时、辨别力、注视次数、眼跳幅度。实验表明：学习与辨认的一致性对人像辨认影响显著,外在特征多少对人像辨认影响不显著。     

学校归属感与青少年手机依赖的关系:学习焦虑的中介效应与同伴关系的调节效应

为探讨学校归属感对青少年手机依赖的影响及其作用机制,基于阶段环境匹配理论,本研究采用问卷法对山东省青岛市65所中学3355名高二年级学生进行调查。结果表明:(1)在控制了性别和上网时间后,学校归属感对青少年手机依赖具有显著的负向预测作用;(2)学习焦虑在学校归属感与青少年手机依赖之间起部分中介作用;(3)学校归属感对青少年手机依赖的直接作用、学习焦虑的中介作用均受到同伴关系的调节,且相对于同伴关系水平低的个体,学校归属感对手机依赖、学校归属感对学习焦虑以及学习焦虑对手机依赖的作用都在同伴关系水平高的个体中更强。本研究有利于揭示学校归属感是如何影响青少年手机依赖的,以及在何种条件下对青少年手机依赖的影响更强/更弱,对移动互联网时代预防青少年手机依赖有一定启示意义。     

注意缺陷多动障碍儿童教育康复线上模式的构建

注意缺陷多动障碍(简称ADHD)是一种常见的儿童神经发育性障碍。当前用于儿童ADHD的传统(线下)教育康复模式存在缺少学业实效、教师低参与、学校管理经验不足以及遇到特殊情况(如疫情)无法服务等问题。本研究在脑电生物反馈认知训练的基础上, 以解决问题和循证研究为设计思路, 为中国ADHD患儿构建教育康复线上模式并进行初步应用。本研究分为3个子研究：研究1采用访谈法和问卷调查法对中国儿童ADHD教育康复的现状调查并分析患儿及关键相关人(家长和教师)需求; 研究2采用随机对照单盲试验(干预组和对照组各为50人), 评价基于脑电生物反馈认知训练(NCT)的教育康复线上模式的有效性; 研究3采用一个更大被试样本量(每组n = 100)的(家长为中介人干预组/教师为中介人干预组/对照组)×(诊断组/亚诊断组)随机对照研究评价由干预中介人(家长或教师)参与的线上模式的有效性, 以及一个纵向质性研究发现关键相关人对于线上模式的接受情况。研究旨在为中国ADHD患儿提供一个有效且好用的教育康复形式。     

粗暴养育与中学生学习投入：状态焦虑与性别的作用

基于儿童学习投入的社会文化情境发展模型和动机与投入之轮理论,构建了一个有调节的中介模型,探讨了粗暴养育与学习投入的关系以及状态焦虑与性别的作用。对852名初中生进行问卷调查,结果发现：（1）粗暴养育与状态焦虑呈显著正相关,与学习投入呈显著负相关,状态焦虑与学习投入呈显著负相关;（2）状态焦虑在粗暴养育与学习投入之间起完全中介作用;性别调节了“粗暴养育→状态焦虑→学习投入”的前半段路径,相对于男性,粗暴养育与状态焦虑的正向联系在女性中更强。     

高中生正念与学习倦怠：基于自我调节学习模型的视角

基于自我调节学习模型的视角,探究正念对高中生学习倦怠的影响,采用正念注意觉知量表、生命意义感量表、津巴多时间洞察力问卷和青少年学习倦怠量表调查863名高中生。结果表明：（1）正念对高中生学习倦怠具有负向预测作用;（2）正念通过未来时间洞察力与生命意义感的独立中介作用及未来时间洞察力与生命意义感的链式中介作用间接影响学习倦怠。因此,正念可以负向预测高中生学习倦怠,提升未来时间洞察力与生命意义感可以缓解高中生学习倦怠,促进高中生身心健康。     

主动性人格对学习投入的影响：领悟社会支持和积极情绪的链式中介作用

基于资源保存理论,采用主动性人格量表、领悟社会支持量表、正性-负性情绪量表和学习投入量表对544名在校大学生进行问卷调查,通过结构方程建模来考察主动性人格、领悟社会支持和积极情绪对学习投入的影响。结果发现,主动性人格、领悟社会支持和积极情绪均能够正向预测学生学习投入;领悟社会支持和积极情绪在主动性人格对学习投入的影响中起到链式中介作用。     

Factor Retention Using Machine Learning With Ordinal Data

Determining the number of factors in exploratory factor analysis is probably the most crucial decision when conducting the analysis as it clearly influences the meaningfulness of the results (i.e., factorial validity). A new method called the Factor Forest that combines data simulation and machine learning has been developed recently. This method based on simulated data reached very high accuracy for multivariate normal data, but it has not yet been tested with ordinal data. Hence, in this simulation study, we evaluated the Factor Forest with ordinal data based on different numbers of categories (2–6 categories) and compared it to common factor retention criteria. It showed higher overall accuracy for all types of ordinal data than all common factor retention criteria that were used for comparison (Parallel Analysis, Comparison Data, the Empirical Kaiser Criterion and the Kaiser Guttman Rule). The results indicate that the Factor Forest is applicable to ordinal data with at least five categories (typical scale in questionnaire research) in the majority of conditions and to binary or ordinal data based on items with less categories when the sample size is large.     

语音训练对幼儿英语语音意识和字母知识的促进

语音意识是影响英语阅读能力的关键因素。本研究结合语音教学法的思想,采用自编的教学材料和语音游戏,通过字母故事和语音训练游戏,训练儿童的语音意识。研究者在北京市一所普通幼儿园选取了无英语学习经验的3岁左右中国幼儿63名,随机分为实验组和控制组,经过8周的语音教学实验,发现接受语音教学的实验组儿童在音节意识、音韵意识、音素意识和字母识别等方面较接受普通英语教学的控制组都有显著提高。结果表明早期有针对性的语音训练可能能够更快地提高幼儿的语音意识。     

Stimulus control of the pigeon's ability to peck a moving target.

Two pigeons were trained to peck whichever of eight keys displayed a white field (SD). The other seven keys displayed a white "X" on a black background (S delta). Each peck to SD produced three-second access to grain, a three-second intertrial interval (ITI), and the next trial. Pecks to S delta produced a three-second timeout (TO) and the same trial. During later sessions the key displaying SD changed every t seconds (t = 3, 2, 1, .5, and .25 sec), requiring the birds to track the position of the SD. Pecks on a ninth key increased t. Several sessions employed novel stimuli to ascertain the controlling stimulus dimensions. Both birds made few errors acquiring the original discrimination. During the tracking sessions, both birds made few errors when t = .5 sec. Only one reliably lengthened t. Data from sessions with novel stimuli indicate that color and form were important aspects of SD and S delta respectively; movement contributed to the final performance.     

Categories and causality: the neglected direction

The standard approach guiding research on the relationship between categories and causality views categories as reflecting causal relations in the world. We provide evidence that the opposite direction also holds: categories that have been acquired in previous learning contexts may influence subsequent causal learning. In three experiments we show that identical causal learning input yields different attributions of causal capacity depending on the pre-existing categories to which the learning exemplars are assigned. There is a strong tendency to continue to use old conceptual schemes rather than switch to new ones even when the old categories are not optimal for predicting the new effect, and when they were motivated by goals that differed from the present context of causal discovery. However, we also found that the use of prior categories is dependent on the match between categories and causal effect. Whenever the category labels suggest natural kinds which can be plausibly related to the causal effects, transfer was observed. When the categories were arbitrary, or could not be plausibly related to the causal effect learners abandoned the categories, and used different categories to predict the causal effect.
