Autism spectrum disorders (ASD) and Williams syndrome (WS) exhibit contrasting forms of emotion comprehension; however, few studies have directly compared the two. In this study, we directly compared six children with ASD, chronological age 3–7, w...

Development of a sense of self is a fundamental process needed for human social interaction. Although functional neuroimaging studies have revealed the importance of medial prefrontal cortex (mPFC) in self-referencing, how this function develops i...

Difficulties in understanding others’ emotions have been widely reported in autism spectrum disorders (ASDs). Many methodologies for evaluating the emotion recognition can be analyzed by matching-to-sample (MTS) procedures. When using movies of so...

To reveal the relation between intellectual disability and the deleted intervals in Williams syndrome, we performed an array comparative genomic hybridization analysis and standardized developmental testing for 11 patients diagnosed as having Will...

Horizontal intracortical projections for agonist and antagonist muscles exist in the primary motor cortex (M1), and reward may induce a reinforcement of transmission efficiency of intracortical circuits. We investigated reward-induced change in M1...

Cognitive disorders in the acute stage of stroke are common and are important independent predictors of adverse outcome in the long term. Despite the impact of cognitive disorders on both patients and their families, it is still difficult to predi...

Deficits in comprehension of others’ emotions have been well documented in children with autism spectrum disorders (ASDs). As to variety of methodological procedures, many of them can be analyzed by matching-to-sample (MTS) procedures. When using ...

Japanese students with developmental disabilities often exhibit difficulties in reading, particularly in Kanji (ideogram) reading, and in acquiring the equivalence relations between pictures, written words, and sounds. Previous research suggested ...

For most of students with autism spectrum disorders (ASD) and Williams syndrome (WS), a rare genetic neurodevelopmental disorder, are known to have intellectual disabilities (ID). Students with ID often show the difficulties in reading. Especially...

Autism is a defiit of social, communicative, and linguistic function said to be caused by brain dysfunction. We have developed a comprehensive intervention program that focuses on early development of communication. In the present study, the progr...

A number of behavioral studies suggest that infant-directed speech (IDS) plays a more important role in facilitating both: a) speech perception, and b) adult–infant social interactions than does adult-directed speech (ADS), and hence that IDS cont...

Reciprocal inhibition of antagonist muscles is crucial for motor skill learning in humans. However, the changes in reciprocal inhibition function during the motor learning process are unknown. The aim of this study was to systematically observe th...

In early training for children with autism spectrum disorders (ASDs), matching-to-sample (MTS) tasks are widely used to teach various language and cognitive skills. However, some problems in conducting MTS training for children with developmental ...

Students with developmental disabilities often have difficulty with writing skills such as tracing, copying, and dictation writing. A student with writing difficulties participated in the present study, which used computer‐based teaching applied i...

We have thus far conducted a special-needs education program using e-learning for students experiencing learning difficulties in regular classrooms. The results for improving cognitive function and an attempt to investigate accompanying changes in...

This study examined the cerebral functional lateralization, from a phonological perspective, in children with autism spectrum disorder (ASD) and typically developing children (TDC). With near infrared spectroscopy, we measured auditory evoked-resp...

The present study aimed to examine the controlling variables for initiating joint attention (IJA) in three children with autism. During the baseline, target objects were presented in a location where the child could see them, but the adult could n...

Students with developmental disabilities often have difficulty in learning the systematic relations between syllables (auditory stimuli) and characters (visual stimuli) required for reading. Two students with developmental disabilities participate...

Many children with autism have severe difficulty in ‘reporting’ on events at schools to mothers at home despite their ability to tact some objects and actions in discrete trial setting. Many studies have attempted to establish tact as labeling in ...

The Picture Exchange Communication System (PECS) is widely used with non-verbal children with autistic disorders as an Augmentative and Alternative Communication (AAC). Most of the participants in prior research on that method, although referred t...

The present study examined the effectiveness of matrix training procedures for establishing adjective-object two-word utterances in children with autism. The procedure included training both receptive and expressive responses in one trial. Partici...

The purposes of the present study were to investigate the resources for formal and informal support for families of children with autism in Malaysia, and, with those findings, study the possibility of Malaysian parents conducting an applied behavi...

We evaluated a computer-based sorting-to-matching procedure to teach matching-to-sample skills to seven young children with developmental disabilities who had failed to demonstrate identity matching-to-sample under the typical training procedure (...

The purpose of the present study was to clarify the type of intensive supervision needed by families who were applying home-based behavioral treatment for children with autism in the absence of constant supervision. Participants were 8 children (a...

Joint visual attention is defined as looking where someone else is looking. The purpose of this study was to examine the conditions for establishing joint visual attention in autistic children who have no functional speech. An experimenter, sittin...

The effects of a self-monitoring procedure on improving academic performance, using 3 academic subjects (Japanese language [Kokugo], social studies, and science), were assessed in a sixth grade student with autism in his home setting. Self-monitor...
