Applied behavior analysis is an evidence-based early developmental intervention. Lovaas (1987) clearly showed that early intensive intervention using discrete trial teaching method (DTT) drastically improved development of children with autism spectrum disorder. Junichi learned DTT from Takafumi Miyoshi who stayed Lovaas's Lab at University of California Los Angeles (UCLA) after the graduation form Department of Psychology at Keio University. Junichi concerned about research of experimental psychology, applied behavior analysis, and developmental science in parallel and extended the scope of innovative research. At his interest, he stayed sabbatical years (2007–2008) at Laura Schreibman's Lab in University of California San Diego (UCSD) as a visiting scholar. At 2010, Junichi invited Laura to Graduated School of Human Relations, Keio University as a visiting professor to receive intensive lectures and academic interaction with graduate students. Mikimasa Omori, Waseda University, attended the lectures as a master student. Schreibman et al (2015) after that integrated applied behavior analysis and developmental science and conceptualized naturalistic developmental behavioral intervention publishing a high impact article. In this interview, Laura, Mikimasa, and Junichi talk about past and future research of early developmental intervention for children with autism spectrum disorder in US and Japan.
