Verbal skills in children with ADHD

The present study examined whether ADHD children exhibit low verbal IQ (VIQ) and distinguishable test profile on the Verbal comprehension (VC) and Freedom from distractibility (FFD) factors, and whether gender influences their verbal abilities. At the Laboratory of Neuropsychology of the Department of Special Education, University of Thessaly, WISC‐III verbal scales were administered to 69 ADHD children (50 boys and 19 girls) and controls who were matched for age and sex. Mean scores for all WISC‐III verbal scales, VIQ, VC and FFD of ADHD children were significantly lower than controls. FFD was found lower than VC and it correlated statistically significantly with VC in ADHD children. No gender differences were found among ADHD children.     

汉语学习的层阶与汉语教学的适切性

汉语所承载的内容包罗万象,可以分为若干个层面,而不同层面包含的内容具有不同的性质与特征,相应的汉语学习就具有层阶性,即从习得汉语的语言符号系统到理解汉语的文化内涵,进而形成汉语的审美与价值观。因此汉语教学应确定目标层次,即从促成记忆的教学入手,进一步促成理解的教学与审美认同的教学,形成汉语学习的阶梯型发展。

Inter-ethnic preferences and ethnic hierarchies in the former soviet union

One-thousand two-hundred and ninety university students from twenty-seven ethnic?national groups across six locations in the former Soviet Union (Novopolotsk in Byelorussia, Kharkov in the Ukraine, Moscow and Nizniy Novgorod in Russia, Ufa in the Bashkir Autonomous Republic and Ulan-Ude in the Buryat Autonomous Republic) participated in 1991–1992 in a survey investigating the existence of ingroup preference in inter-ethnic contact, ingroup consensus on an ethnic hierarchy of outgroups and the measure of intergroup consensus on an ethnic hierarchy among the ethnic?national groups in each location. Hypotheses about ingroup preference, ethnic hierarchies and consensus were derived from realistic group conflict theory, social identity theory and from the assumption that outgroup preferences reflect considerations of the status effects of intergroup contact. It appeared that the last type of hypothesis could explain most of the results.

Validating Student Score Inferences With Person‐Fit Statistic and Verbal Reports: A Person‐Fit Study for Cognitive Diagnostic Assessment

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way.
