The Development of the Toddler Behavior Screening Inventory

The purpose of the present study was to develop the Toddler Behavior Screening Inventory (TBSI) for rapidly assessing maternal reports of toddler behavior problems. The TBSI is a 40-item measure intended for use by pediatricians, psychologists, and other child-care professionals. A group of mothers (n = 312) rated the initial 93-item TBSI in terms of behavior frequency and parental perception of the behavior as problematic. Following item elimination, 40 items were retained due to being both frequent and problematic at all toddler age levels. Data were obtained with a new sample of mothers (n = 581) and showed the TBSI to possess good reliability and validity.

Contradictory asymmetries in body and weapon size,and assessment in fighting male prawns,Macrobrachium rosenbergii

Asymmetries in weapon size and body size, both contributing to an animal's fighting ability, may be contradictory in two fighting Macrobrachium rosenbergii males: One male may be larger in body size but smaller in cheliped size than its rival. The aim of the study was to determine the relevance of these two asymmetries in the assessment of relative fighting ability, and to reveal the effect of the asymmetry level on the structure of contests. Thirty contests were staged between male prawns from the ‘blue-clawed’ morphotype and the ‘orange-clawed’ morphotype. The blue-clawed males were 0%, 10%, or 20% larger in cheliped length but 93%, 45%, or 25% smaller in weight, respectively (n = 10), as compared to their orange-clawed opponents. The blue-clawed males with 10% and 20% advantage in cheliped length almost invariably won the contests. When similar in cheliped length, the 93% smaller blue-clawed males still won half of the contests. This indicated that the prawns ignored large asymmetries in body size even when no asymmetry in cheliped size existed. The results suggest that only cheliped size is used by M. rosenbergii males in the assessment of fighting ability. The effect of asymmetry level on contest structure was apparent only with the increase from 10% to 20% difference in cheliped size: Both the frequency and the intensity of fighting were lower in contests between prawns with 20% difference, as compared to 0% and 10% difference in cheliped length.

浅谈元认知知识的培养及其评定

元认知知识是元认知的主要成份之一,它由三部分知识组成:认知主体方面的知识、认知任务方面的知识和认知策略方面的知识。在教学过程中加强对学生元认知知识的培养与训练,有利于学生学会学习,从而达到最佳的学习效果。元认知知识的评定难以在大规模考试中实现,应该综合运用多种方法在日常教学中加以评定,并作为主要任务之一纳入学生的形成性评价。     

Individuals differ in the attentional blink: Mental speed and intra-subject stability matter

The failure to correctly report two targets (“T₁”, “T₂”) that follow each other in close temporal proximity has been called the “attentional blink” (AB). The AB has, so far, mainly been studied using experimental approaches. The present studies investigated individual differences in AB performance, revealing (among further findings) a high positive correlation between the accuracies of detecting the two targets correctly (r = 0.69); and between T₂∣T₁ accuracy and psychometric intelligence (0.41 ≤ r ≤ 0.43) and RT variability in short-term and working memory (− 0.38 ≤ r ≤ − 0.45). Together, these results support important aspects of major theoretical accounts of the AB from an individual differences perspective and introduce intelligence and intra-subject stability as contributing factors in AB performance.     

Individual differences in emotional intelligence and incidental memory of words1

Participants were required to complete the Japanese version of the Emotional Skills and Competence Questionnaire ( Toyota, Morita, & Tak?i?, 2007 ) to assess their level of emotional intelligence. Then they were asked to rate the pleasantness of an episode that each target reminded them of, followed by unexpected free recall tests. Participants with high emotional intelligence recalled targets with pleasant, neutral, and unpleasant episodes equally. However, for participants with low emotional intelligence, targets with neutral episodes were recalled less than those with pleasant or unpleasant ones. These results were interpreted as showing that the level of emotional intelligence determined the effectiveness of neutral episodes on targets as retrieval cues.     

Relationships between three auditory inspection time tasks and processing speed

This study investigated the relationship between a spatial auditory inspection time task and previous versions of AIT, as well as the relationships of these tasks with visual inspection time (VIT) and general speediness (Gs). A total of 96 university undergraduates (age mean (M) = 20.0 years, standard deviation (SD) = 4.0 years) completed three AIT tasks, VIT, auditory reaction time (ART) and visual reaction time (VRT), and two Gs marker tests. Auditory inspection time‐spatial (AIT‐S) did not relate to VIT, but it did relate to the Gs marker tests. It also loaded moderately on a Gs factor along with VIT. Neither of the alternate AIT tasks showed any consistent relationships to reaction time (RT) or Gs measures. The AIT‐S task did, however, share substantial variance with its predecessors, suggesting that performance on all AIT tasks relies to some extent on similar processes. Further research is required to determine the nature of these processes.     

中学生自我同一性地位、情绪表达及其相关研究

本文根据埃里克森、玛西娅、加藤厚等人的自我同一性理论,对某中学初一至高三学生的自我同一性及情绪表达进行问卷调查研究。研究发现,中学生自我同一性发展各个维度总体呈"低-高-低-高"的发展趋势。高一是自我同一性发展的转折时期,在现在的自我投入上处于低谷,与其他各年级存在显著性差异。同时自我同一性度数分布也存在显著性差异。中学生的正性情绪表达在性别上存在显著差异。从初一至高三,学生的情绪表达三个维度都呈下降趋势,高二、高三学生的正性情绪表达、负性情绪表达、情绪表达强度显著低于初一、初二学生。中学生现在的自我投入和将来自我投入的愿望与正性情绪表达呈显著正相关。     

A Bayesian-optimal principle for learner-friendly adaptation in learning games

Adaptive learning games should provide opportunities for the student to learn as well as motivate playing until goals have been reached. In this paper, we give a mathematically rigorous treatment of the problem in the framework of Bayesian decision theory. To quantify the opportunities for learning, we assume that the learning tasks that yield the most information about the current skills of the student, while being desirable for measurement in their own right, would also be among those that are efficient for learning. Indeed, optimization of the expected information gain appears to naturally avoid tasks that are exceedingly demanding or exceedingly easy as their results are predictable and thus uninformative. Still, tasks that are efficient for learning may be experienced as too challenging, and the resulting failures can lower motivation. Therefore, in addition to quantifying the expected informational benefit for learning of any prospective task to be presented next, we also model the expected motivational cost of its presentation, measured simply as the estimated probability of failure in our example model. We propose a “learner-friendly” adaptation algorithm that chooses the learning tasks by optimizing the expected benefit divided by the expected cost. We apply this algorithm to a Rasch-like student model implemented within a real-world application and present initial results of a pilot experiment.     

PASS理论语境中的认知过程(英文)

计划-注意-同时性加工-继时性加工,这些基本PASS概念的提出,是为了给传统上将智力作为一个笼统构念的做法提供某种替代的选择。在这一新的理论途径中,我将一般能力分解为对主要认知过程的研究,其中每个认知过程均有其行为、认知和神经心理成分,而且重要的是,每个认知过程均有相应的一组评估测量任务。PASS模型,这一理论框架能够充分包容体现于教育和组织行为中的广泛一系列认知功能。
