Tap,swipe, and build: Parental spatial input during iPad® and toy play

Despite the increase in the use of interactive technological devices, little is known about the impact that play context has on the production of spatial language by parents. To investigate whether there is differential parental spatial input afforded by play contexts with their preschoolers, 34 children (20 girls, 14 boys) and their primary caregivers engaged in 30‐min 3‐dimensional (3D) spatial play using blocks and puzzles and virtual 2‐dimensional (2D) spatial play using an iPad^® in 2 separate home visits. There were no significant differences in the average amount of spatial talk and the number of spatial categories used by parents in both 3D and 2D play contexts. However, the amount of parental spatial talk decreased significantly with older preschoolers using the iPad^®. In the 3D play contexts, parents produced more words related to spatial dimensions, location and directions, and continuous amount than in the 2D play contexts. However, in the 2D play contexts, they produced more words associated with orientations and transformations as well as deictics than in the 3D play contexts. Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input by supporting parents and caregivers with best practices.

Highlights

• The present study examines the differences in parental spatial talk when using traditional versus technology‐based learning tools with their preschoolers.
• Two 30‐min home observations of parent–child dyads playing blocks and puzzles versus spatial apps on an iPad^®. No significant differences in the amount of parental spatial talk and the number of spatial categories in both play contexts were found.
• Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input.

     

学校心理咨询若干倾向性问题的思考

本文针对当前学校心理咨询中普遍存在的重视"调适性心理咨询",忽视"发展性心理咨询";重视心理异常中"心理障碍"的矫治,忽视"一般心理问题"的调控和重视成人心理异常表现模式的套用,忽视学生心理异常表现的年龄特征等倾向,提出并论述了学校心理咨询"咨询类型"的侧重点在于发展性心理咨询,"调适矫正"的着眼点在于心理异常中"一般心理问题"的调控,"分析判别"的出发点在于以学生各年龄阶段心理异常特有表现为依据的观点,为进一步强化学校心理咨询的科学性,顺利进行心理健康教育,以提高学生心理素质提供了理论依据.     

Comparison of Scoring Criteria for Clock Drawing Test

This study compared clock drawings by 42 medically hospitalized patients with a mean age of 51.9 (SD = 10.1) years, using four sets of published scoring criteria to determine comparability of classification and to assess validity by comparison to other measures of cognitive functioning. We found impairment in 20 of 42 cases using the criteria of Mendez et al. (1992); 11 of 42 cases by Sunderland et al. (1989); 9 of 42 cases with Freedman et al. (1994); and 8 of 42 cases according to Rouleau et al. (1992). Kappa coefficients of impairment status between sets of scoring criteria ranged from .41 to .86. Pearson correlations of raw scores between schemes ranged from .72 to .94. All except Sunderland et al. were significantly correlated with the Standardized Mini-Mental State Examination. All correlated significantly with the Wechsler Adult Intelligence Scale–Revised Block Design; however, only Mendez et al. correlated significantly with the Neurobehavioral Cognitive Status Examination. On the basis of these results and our experience, we recommend using the Freedman scoring scheme.     

伦理何为

伦理学是“成人”,“做人”之维。人离不开伦理,伦理学首先是“成人”之道。“人”成为什么样的人也离不开伦理,伦理学又是“做人”之维。伦理要内化成人心理的存在,才能成为“成人”之道,“做人”之维。道德建设要符合“成人”与“做人”的要求。

允许CAT题目检查的区块题目袋方法

允许题目检查能够促进计算机化自适应测验(CAT)在实际中的应用。在不影响能力估计精度和测验公平性的前提下, 允许CAT题目检查能够缓解考生考试焦虑, 减少无关因素引起的测量误差。区块题目袋方法是连续区块方法与题目袋方法的结合, 不仅能允许CAT题目检查, 还能够弥补题目袋方法的不足。研究结果表明：(1)合理作答策略下, 区块题目袋方法的估计精度在低能力水平上要优于题目袋方法; (2)在应对类似Wainer作答策略时, 区块题目袋方法的估计精度在所有能力水平上均优于题目袋方法。(3)随着区块数的增加, 区块题目袋方法的能力估计精度越接近无修改的基线水平。     

从《周易》与柏格森的角度论生存的本质

生存是事物存在的基础和本体,故曰"天地之大德曰生"。生存包括变化、生长和元。变化是品物流形;生长是有序的变化;元是生长的基础。乾坤为元,万物始生。阴阳感应催动了生长和变化。生长是元之生长与变化。

Nonmetric individual differences multidimensional scaling: An alternating least squares method with optimal scaling features

A new procedure is discussed which fits either the weighted or simple Euclidian model to data that may (a) be defined at either the nominal, ordinal, interval or ratio levels of measurement; (b) have missing observations; (c) be symmetric or asymmetric; (d) be conditional or unconditional; (e) be replicated or unreplicated; and (f) be continuous or discrete. Various special cases of the procedure include the most commonly used individual differences multidimensional scaling models, the familiar nonmetric multidimensional scaling model, and several other previously undiscussed variants.The procedure optimizes the fit of the model directly to the data (not to scalar products determined from the data) by an alternating least squares procedure which is convergent, very quick, and relatively free from local minimum problems.The procedure is evaluated via both Monte Carlo and empirical data. It is found to be robust in the face of measurement error, capable of recovering the true underlying configuration in the Monte Carlo situation, and capable of obtaining structures equivalent to those obtained by other less general procedures in the empirical situation.This project was supported in part by Research Grant No. MH10006 and Research Grant No. MH26504, awarded by the National Institute of Mental Health, DHEW.
