This study examined the similarities/differences between the social phenotypes of Williams syndrome (WS) and autism spectrum disorder (ASD). As cultural norms may affect symptom evaluation, this study administered the Social Responsiveness Scale-2 to Japanese individuals with WS (n = 78, 4.4-44.0 years) and ASD (n = 75, 4.7-55.4 years). The scores…

This article outlines the development of a 16-item instrument for measuring language learner's foreign language self-efficacy (SE) concerning their speaking and listening skills through repeated administrations to groups of Japanese tertiary students. Responses were analysed through the Rasch model, which allows researchers to investigate…

Purpose: Auditory-perceptual evaluation is essential for the assessment of voice quality. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) provides a standardized protocol and assessment form for clinicians to analyze the voice quality and has been adapted into several different languages. The aims of this study were to develop the…

Accreditation can serve as an accountability mechanism for higher education, ensuring institutions meet specific standards, which can be impacted by various factors including the regulatory environment of each country or local jurisdiction as well as an institution's mission, enrollment, and student success trends. In addition, higher education…

This study examined the efficiency of using the same rating scale categories in measuring affective constructs for students with distinctive levels of achievement. Data used in this study came from the Trends in Mathematics and Science Study (TIMSS) 2011, as a case, on the three scales that were designed to measure eighth graders' attitudes…

Although proponents of extensive reading (ER) have recommended easy reading material, book difficulty has been poorly defined and operationalized in previous studies. The present study argues for the use of perceived text difficulty for operationalizing book difficulty based on empirical findings (Holster et al., 2017), reading purposes in ER, and…

Studies on Global Englishes (GE)-related pedagogical and curricular innovations emphasize the importance of exposing students to the diversity of English and its users. However, they do not provide direct evidence of changes in students' attitudes. The reliability and validity of existing quantitative instruments for measuring students' attitudes…

In this paper we use novel data to test the direct and indirect paths between teacher self-efficacy and student outcomes. This includes how teacher self-efficacy is linked to student, teacher, and expert rater views of lesson quality. Our results illustrate how the link between teacher self-efficacy and instructional quality is sensitive to how…

The present study investigated how the eye contact perception of ingroup and outgroup faces by Japanese adults with high-functioning autism spectrum disorder differed from that of age-, sex-, and IQ-matched typically developing individuals. The autism spectrum disorder and typically developing individuals were equally likely to perceive subtly…

This paper analyzes writing tasks in academic writing textbooks for Japanese university students, focusing on the organization and difficulty of these tasks based on the Common European Framework of Reference for Languages (CEFR). A total of 411 writing tasks from 30 textbooks were coded by two experienced Japanese English teachers. The author…

The study examined the impact of a first language's summarizing skill and second language vocabulary size on summary performances in a second language. A total of 40 English as a Foreign Language (EFL) learners from a Japanese university with a mixed level of English language proficiency were asked to write a summary in English (i.e., their…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

The elicited imitation task (EIT), in which language learners listen to a series of spoken sentences and repeat each one verbatim, is a commonly used measure of language proficiency in second language acquisition research. The "TOEFL® Essentials"™ test includes an EIT as a holistic measure of speaking proficiency, referred to as the…

This report describes the development of efficient second language (L2) writing assessment tasks designed specifically for low-proficiency learners of English to be included in the "TOEFL® Essentials"™ test. Based on the can-do descriptors of the Common European Framework of Reference for Languages for the A1 through B1 levels of…

The study evaluated a recently postponed national test policy on the use of external agencies' English tests measuring four skills for Japanese university admission purposes. Using Kunnan's principles of fairness and justice, we generated and evaluated three claims regarding the test policy: vocabulary coverage of the tests, the justifiability of…
