Structure also supports autonomy: Measuring and defining autonomy‐supportive teaching in Japanese elementary foreign language classes

Recent discussions of autonomy have included the perspective that, as a basic human need across cultural environments, it includes not only choice but also personal endorsement of action. The present study focused on the cultural experience of autonomy‐support in Japanese elementary school foreign language classes. Three studies were conducted to investigate how students understand autonomy‐supportive teaching. In Study 1, exploratory focus groups defined cultural perspectives on autonomy‐support and structure. Exploratory and confirmatory factor analysis indicated that clarity, pacing, and teachers' positive affect correspond to students' perception of supportive teaching. Study 2 investigated teacher support in relation to in‐class engagement using longitudinal structural equation modeling. The results indicated a strong relationship between perceptions of support and classroom behavioral engagement, with stable effects over time. Study 3 longitudinally investigated teacher support in relation to students' perceptions of personal autonomy, relatedness, and competence need satisfaction. Findings show a strong positive relationship between teacher support and need satisfaction with high test‐retest reliability. Discussion focuses on how autonomy need satisfaction is experienced in different cultures with differing social norms.     

Electrical properties and local structure of n-type conducting amorphous indium sulphide

An n-type amorphous chalcogenide, In₄₉S₅₁, having a band gap of 1.9eV, has been found. The conductivity in as-prepared films was ～10^?4?S?cm^?1, which increased to 1?×?10^?1?S?cm^?1 on post-annealing at 125°C in vacuum, accompanied by a reduction in the sulphur content of the films. TEM observations showed the amorphous nature of the films before and after annealing. Both Seebeck and Hall coefficients are negative, indicating that the major carriers are electrons. The Hall mobility can be as large as 26?cm²?V^?1?s^?1 at 300?K. No significant changes to the optical absorption were observed upon annealing. Analysis of the X-ray radial distribution function reveals that the sulphur atoms have four-fold coordination, making the structure more rigid than conventional amorphous chalcogenides in which the chalcogen is alloyed to elements of group IV or V of the periodic table. We tentatively associate the electron carrier generation with the formation of sulphur vacancies.     

Usage of semantic representations in recognition memory

Meanings of words facilitate false acceptance as well as correct rejection of lures in recognition memory tests, depending on the experimental context. This suggests that semantic representations are both directly and indirectly (i.e., mediated by perceptual representations) used in remembering. Studies using memory conjunction errors (MCEs) paradigms, in which the lures consist of component parts of studied words, have reported semantic facilitation of rejection of the lures. However, attending to components of the lures could potentially cause this. Therefore, we investigated whether semantic overlap of lures facilitates MCEs using Japanese Kanji words in which a whole-word image is more concerned in reading. Experiments demonstrated semantic facilitation of MCEs in a delayed recognition test (Experiment 1), and in immediate recognition tests in which participants were prevented from using phonological or orthographic representations (Experiment 2), and the salient effect on individuals with high semantic memory capacities (Experiment 3). Additionally, analysis of the receiver operating characteristic suggested that this effect is attributed to familiarity-based memory judgement and phantom recollection. These findings indicate that semantic representations can be directly used in remembering, even when perceptual representations of studied words are available.     

Developmental order driving the relationship between executive functions and theory of mind: a case study

Several studies have suggested there is a developmental link between executive functions and theory of mind. However, the developmental order driving the relationship is not well understood. The main reason is that the development of executive function parallels the development of theory of mind in normally developing children. In this paper, a case (H.Y.) is reported. H.Y. had lived in a persistent vegetative state for 6 years after encephalitis at the age of 10. He showed a developmental order driving the relationship between executive functions and theory of mind. These findings are consistent with recent suggestions that development of executive function might be important as a predecessor of either the ability to understand false beliefs or the ability to express that understanding.     

Parent Involvement in Secondary Special Education and Transition: An Exploratory Psychometric Study

An increased level of parent involvement in education has been identified as a predictor of positive postschool outcomes for students with disabilities who have traditionally experienced lower rates of employment and postsecondary education than their peers without disabilities. The purpose of this study was to explore the factor structure of scales adapted from the Hoover-Dempsey and Sandler Model of Parent Involvement that might be used to predict parent involvement in secondary special education. An iterative adaption process included adding and revising scale items to reflect parent beliefs and involvement activities related to transition planning and secondary education for parents of high school students with disabilities. Participants were 149 parents of students with disabilities, ages 16–21. Two exploratory factor analyses (EFA) were conducted to examine the psychometric properties of the scales. Results of the EFA for involvement activities suggested a three-factor solution including: Future Planning; Home-based Involvement; and Agency/School-based Involvement. Results of the EFA for Motivators for Involvement suggested a seven-factor solution including: Parent Expectations for the Future; General School Invitations; Role Construction; Perceptions of Time and Energy; Knowledge, Skills, and Self-efficacy; Specific Child Invitations, and Specific Teacher Invitations. Implications and future research directions are discussed.     

Phonatory initiation,termination, and vocal frequency change reaction times of stutterers

Four types of voice reaction times were investigated for eight adult stutterers and eight control subjects using a vocal shadowing paradigm. These were voice initiation and termination reaction times (VIT and VTT, respectively) and voice frequency-shift intiation and termination reaction times (SIT and STT, respectively). Results indicated that the stutterers were slower in VIT, but were as fast as their control subjects in VTT, SIT, and STT. It was suggested that a laryngeal discoordination problem of stutterers lies primarily in the stage of adduction (turning on the voicing) rather than in the stage of abduction (turning off the voicing) or in finer frequency control at the larynx.
