多级评分聚类诊断法的影响因素

从测验和被试两个层面探讨了属性数目、属性层级关系、被试知识状态分布、属性层级误设和Q矩阵误设等因素对GRCDM的影响, 以进一步考察GRCDM的特性。研究发现：(1)GRCDM对属性数目无依赖, 随属性数目的增多判准率反而增高; (2)被试知识状态分布对GRCDM判准率高低无影响; (3)属性层级误设对GRCDM的影响与属性层级类型有关, 当属性层级为无结构型和发散型时, “属性层级关系错乱”的判准率降幅最大; (4)Q矩阵误设对GRCDM的影响因层级关系而异, 收敛型和发散型受影响较小, 无结构型和线型的判准率在属性既冗余又缺失时降幅最大。     

Using The Self-Advocacy Strategy to Increase Middle Graders' IEP Participation

This study investigated the effects of teaching middle grade students with disabilities to participate in their IEP meetings using The Self-Advocacy Strategy. Four students with high-incident disabilities were taught to be active participants in their IEP meetings. Student contributions, along with scores on The Arc's Self-Determination Scale, were used to measure the effectiveness of the strategy. Findings from this study indicate that The Self-Advocacy Strategy is an effective instructional tool that can be used to teach middle grade students with disabilities to be active participants in their IEP meetings.     

Regular Minimality and Thurstonian-type modeling

A Thurstonian-type model for pairwise comparisons is any model in which the response (e.g., “they are the same” or “they are different”) to two stimuli being compared depends, deterministically or probabilistically, on the realizations of two randomly varying representations (perceptual images) of these stimuli. The two perceptual images in such a model may be stochastically interdependent but each has to be selectively dependent on its stimulus. It has been previously shown that all possible discrimination probability functions for same–different comparisons can be generated by Thurstonian-type models of the simplest variety, with independent percepts and deterministic decision rules. It has also been shown, however, that a broad class of Thurstonian-type models, called “well-behaved” (and including, e.g., models with multivariate normal perceptual representations whose parameters are smooth functions of stimuli) cannot simultaneously account for two empirically plausible properties of same–different comparisons, Regular Minimality (which essentially says that “being least discriminable from” is a symmetric relation) and nonconstancy of the minima of discrimination probabilities (the fact that different pairs of least discriminable stimuli are discriminated with different probabilities). These results have been obtained for stimulus spaces represented by regions of Euclidean spaces. In this paper, the impossibility for well-behaved Thurstonian-type models to simultaneously account for Regular Minimality and nonconstancy of minima is established for a much broader notion of well-behavedness applied to a much broader class of stimulus spaces (any Hausdorff arc-connected ones). The universality of Thurstonian-type models with independent perceptual images and deterministic decision rules is shown (by a simpler proof than before) to hold for arbitrary stimulus spaces.     

各种分类标准在儿童分类中的竞争

在已有研究的基础上进一步考查类概念,颜色、形状和主题关系四种主要分类标准在儿童分类操作中的竞争力;并衡量各分类标准被选择的次序和差别度。被试是４－８岁儿童１５０名。选取儿童熟悉的７个类概念。采用概念同定匹配和配对法。结果表明：在５岁以后类概念呈快速发展,８岁达基本掌握水平;四种分类标准中感知因素竞争力最弱,主题关系在５岁居高峰;各种分类标准强弱的等第次序自６岁后稳定一致;分类标准的差别度随年龄增长而加大,６－７岁是差别度变化的转折点。     

Measuring social skill in grade school boys

This study examined positive and negative assertive skill in 60 elementary school boys, grades 3–8. Subjects' role-played responses to standard analogue situations requiring expression of positive and negative assertion were videotaped and rated retrospectively. High- and low-assertive subjects were identified through ratings of overall assertiveness. Results of this study indicate that (1) high- and low-assertive subjects differ on a number of response components which are related to age level and type of assertive situation (positive vs. negative), (2) assertive skill is associated with role-taking (or decentering) ability, (3) teachers tend to perceive their assertive boys as more sociable and interpersonally sensitive than unassertive boys, (4) there is essentially no correlation between teachers' ratings of aggressiveness and separate behavioral ratings of assertive skill, and (5) behavioral ratings of assertiveness show little relationship to self-report or teachers' ratings of assertiveness.This article is based on a dissertation submitted to the Faculty of the Graduate School of Loyola University of Chicago in partial fulfillment of the requirements for the Degree of Doctor of Philosophy. The study was conducted under the direction of the second, third, and fourth authors.     

提高小学四年级学生情绪胜任力的干预研究

基于将情绪、认知和行为发展相整合的理念,试图通过团体干预活动,提高小学生的情绪胜任力。结果表明,6个系列干预活动能够有效提高小学四年级学生的情绪词汇量、情绪识别能力和情绪调节能力。团体内同伴提名和教师访谈显示,干预活动有助于促进学生的积极心境、自我控制能力和亲社会社交能力的发展,有助于减少攻击、同伴拒绝等适应不良行为。     

What difference reveals about similarity

Detecting that two images are different is faster for highly dissimilar images than for highly similar images. Paradoxically, we showed that the reverse occurs when people are asked to describe how two images differ--that is, to state a difference between two images. Following structure-mapping theory, we propose that this disassociation arises from the multistage nature of the comparison process. Detecting that two images are different can be done in the initial (local-matching) stage, but only for pairs with low overlap; thus, "different" responses are faster for low-similarity than for high-similarity pairs. In contrast, identifying a specific difference generally requires a full structural alignment of the two images, and this alignment process is faster for high-similarity pairs. We described four experiments that demonstrate this dissociation and show that the results can be simulated using the Structure-Mapping Engine. These results pose a significant challenge for nonstructural accounts of similarity comparison and suggest that structural alignment processes play a significant role in visual comparison.     

Development and validation of a facial expression database based on the dimensional and categorical model of emotions

ABSTRACT

The present study describes the development and validation of a facial expression database comprising five different horizontal face angles in dynamic and static presentations. The database includes twelve expression types portrayed by eight Japanese models. This database was inspired by the dimensional and categorical model of emotions: surprise, fear, sadness, anger with open mouth, anger with closed mouth, disgust with open mouth, disgust with closed mouth, excitement, happiness, relaxation, sleepiness, and neutral (static only). The expressions were validated using emotion classification and Affect Grid rating tasks [Russell, Weiss, & Mendelsohn, 1989. Affect Grid: A single-item scale of pleasure and arousal. Journal of Personality and Social Psychology, 57(3), 493–502]. The results indicate that most of the expressions were recognised as the intended emotions and could systematically represent affective valence and arousal. Furthermore, face angle and facial motion information influenced emotion classification and valence and arousal ratings. Our database will be available online at the following URL. https://www.dh.aist.go.jp/database/face2017/.     

Assessing and Facilitating School Readiness for Microcomputers

Microcomputers represent a complex educational innovation requiring a planned change approach to program implementation. In this paper, the AVICTORY approach, a framework for assessing organizational readiness for microcomputers, is delineated. A case illustration is presented to demonstrate the relevance of the approach and a strategy for operationalizing and measuring organizational readiness is provided. Activities which may facilitate school readiness for microcomputers are also discussed.
