Japan's Social Thinking and Academic Readiness Training (START) program Academic Readiness (AR) lesson aims to improve self-regulation, executive function, and behavior problems in kindergarten children, but the effects of the START program AR lessons in unfavorable circumstances are unclear. Therefore, this study investigated the effects of the START program AR lesson in affected areas after the Great East Japan Earthquake. A cluster randomized trial was conducted with 111 5-year-old children in two kindergartens in Miyagi Prefecture to evaluate the effectiveness of the six-week AR lesson. One kindergarten was randomly chosen to implement the AR lesson, and the other maintained standard education. In the intervention group, trained classroom teachers provided the children with a 20-min AR lesson once a week. Executive function, behavioral self-regulation, and internalizing and externalizing problem behaviors were measured before and after the six-week intervention. The intervention group showed improved inhibitory control and enhanced behavioral self-regulation compared with the standard practice group. In addition, teachers' evaluations showed that children's internalizing and externalizing problem behaviors improved significantly. The results indicate that the START program AR lesson was effective in enabling teachers to help students improve executive function, self-regulation, and problematic behaviors. Therefore, educators and policy-makers should consider implementing the START program AR lesson in kindergartens after a disaster.

The "first-grade problem" of the lack of concentration, listening, and following of instruction has been widely identified among Japanese kindergarten students. To promote their executive functioning and self-regulation to prevent this issue, we developed the Social Thinking and Academic Readiness Training (START) program. The experimental group in which the program was implemented contained 79 children (average age = 73.22 months), and the standard practices group contained 70 children (average age = 72.91 months). Before and after the intervention, the children underwent tasks to test their behavioral self-regulation and executive function (working memory). For behavioral self-regulation, a significant interaction occurred between condition (experimental and standard practices) and time (pre- and post-test), suggesting that these 6 START lessons promoted self-regulation. However, no effects were found on either auditory or visual memory. Teacher reports in surveys were consistent with the executive functioning outcomes, reporting improvement in children's concentration, listening, and self-regulation skills.

The purpose of the present study was to clarify comprehensively how and to what extent inhibition, spatial working memory (WM), and auditory WM influence agility, balance, and dexterity of motor coordination and comprehensive physical ability in kindergarteners. Participants were 43 children between the ages of 4 and 5 years old. The children performed executive function (inhibition and WM) and motor coordination tasks, and a teacher evaluated their comprehensive physical abilities. Results showed that spatial WM was significantly related to auditory WM, executive functions were significantly related to agility, and agility was significantly related to comprehensive physical ability. Furthermore, using structural equation modelling, we investigated whether executive functions influenced comprehensive physical ability via motor coordination. Results showed a significant correlation between spatial WM and auditory WM. Executive functions, including inhibition, spatial WM, and auditory WM, predicted comprehensive physical ability via agility of motor coordination in the kindergarteners.

The present study examined gender differences in kindergarten students' ability for behavioural self-regulation and executive function in East Japan. One hundred and eleven 5-year-old children were assessed on behavioural self-regulation, inhibitory, and working memory tasks (direct measurement). Children's responses to the teacher's instructions were video-recorded and analysed (class room observation). Teachers assessed behaviour problems in the classroom. Results demonstrated that, while there were no significant gender differences in direct measurement or classroom observations, there were gender differences in teachers' evaluation of social problems, attention problems, and aggressive behaviour, with girls demonstrating lowere levels of problem than boys. These results suggest that teachers' evaluation of behavioural problem could be biased by gender. Possible reasons for this discrepancy were discussed.
