Background: The diagnosis of Developmental Coordination Disorder (DCD) requires a precise assessment of motor skills via a standardized tool such as the Movement Assessment Battery for Children-Second Edition (MABC-2). Although the MABC-2 has been widely used in English-speaking countries, to the best of our knowledge, no studies have examined its applicability to Japanese children. Thus, it has been difficult to diagnose DCD in Japan.
Aims: As a preliminary investigation preceding its formal standardization in Japan, we examined the applicability of the MABC-2.
Methods and procedures: Participants comprised 132 typically developing Japanese children who completed a test set of the MABC-2 for Age Band 2. We analyzed both internal consistency and factorial validity for our Japanese sample. We also included a comparison between our sample of Japanese children and the normative sample of the MABC-2, as well as an examination of gender differences.
Outcomes and results: Our results indicated acceptable internal consistency and scale homogeneity. High factorial validity, which has not been examined in other populations, was also confirmed for the test set. Moreover, we found differences in component scores between the Japanese and normative children with respect to Manual Dexterity and Balance. We also found that girls obtained superior Manual Dexterity and Balance scores compared with boys.
Conclusions and Implications: The present findings represent the first step towards the standardization of the MABC-2 in a Japanese population. (C) 2016 The Japanese Society of Child Neurology. Published by Elsevier B.V. All rights reserved.

The purpose of this study was to elucidate the association between children's behavior (i.e., prosocial and problematic behavior) and the parenting style (i.e., laxness and overreactivity) of their caregivers by using longitudinal data in the Japanese population. These data were collected when the children were 7.5 and 9 years. We proposed three hypotheses: children's behavior at 7.5 years will predict their behavior at 9 years; children's behavior at 7.5 years will predict the parenting of their caregivers; and the parenting style of caregivers will affect their children's behavior at 9 years. We evaluated children's behavior and parenting behavior using a strength and difficulties questionnaire and a parenting scale. The hypotheses were tested using structural equation modeling (SEM). The results of the SEM showed that children's behavior at 7.5 years predicted their behavior at 9 years. Children's problematic behavior at 7.5 years triggered over-reactive parenting in their caregivers at 9 years, which increased problematic behavior and decreased prosocial behavior in the children at 9 years. These findings indicate the association between children's behavior and the parenting style of caregivers in Japan.

<p>We recorded VEPs elicited with new developed low spatial frequency, high temporal frequency and low contrast visual stimuli (M stimuli) to evaluate magnocellular function in both 8 patients with glaucoma or 5 patients with ocular hypertension and 13 normal subjects. VEPs were recorded from Oz electrodes, and analyzed with complex demodulation methods. Peak amplitudes were plotted as a function of the log of the stimulus contrast. The VEP contrast thresholds were determined by a linear extrapolation to zero amplitude. VEP peak amplitudes with 10% and 15% contrast stimuli were lower and contrast thresholds were higher in glaucoma group and ocular hypertension group (<i>p</i><0.05). Contrast thresholds of 6 out of 13 patients were higher than the normal range. M stimuli-elicited-VEPs may be useful to evaluate the early functional impairment in patients with glaucoma or ocular hypertension.</p>

Phonological awareness is essential for reading, and is common to all language systems, including alphabetic languages and Japanese. This cognitive factor develops during childhood, and is thought to be associated with shifts in brain activity. However, the nature of this neurobiological developmental shift is unclear for speakers of Japanese, which is not an alphabetical language. The present study aimed to reveal a shift in brain functions for processing phonological information in native-born Japanese children. We conducted a phonological awareness task and examined hemodynamic activity in 103 children aged 7-12 years. While younger children made mistakes and needed more time to sort phonological information in reverse order, older children completed the task quickly and accurately. Additionally, younger children exhibited increased activity in the bilateral dorsolateral prefrontal cortex (DLPFC), which may be evidence of immature phonological processing skills. Older children exhibited dominant activity in the left compared with the right DLPFC, suggesting that they had already acquired phonological processing skills. We also found significant effects of age and lateralized activity on behavioral performance. During earlier stages of development, the degree of left lateralization appears to have a smaller effect on behavioral performance. Conversely, in later stages of development, the degree of left lateralization appears to have a stronger influence on behavioral performance. These initial findings regarding a neurobiological developmental shift in Japanese speakers suggest that common brain regions play a critical role in the development of phonological processing skills among different languages systems, such as Japanese and alphabetical languages.

Although atypical processing of biological motion (BM) in individuals with autism spectrum disorder (ASD) has been reported, the temporal profile of the neural response to BM is not well explored. In the current study, event-related potentials (ERPs) were measured in 12 individuals with ASD, aged 8-22 years, and 12 age- and gender-matched normal controls, to investigate the electrophysiological response to BM and a control visual stimulus. By introducing a novel experimental paradigm that can dissociate the electrophysiological responses to motion processing and the global shape processing of BM, we found that: (1) the timing of the response was preserved in ASD groups, whereas (2) the ERP response to BM was significantly enhanced compared with scrambled point-light motion (SM) in normal controls; the responses to both BM and SM were not significantly different in subjects with ASD. Because we did not find a significant group effect on the peak and mean amplitude induced by BM, it is presumed that this atypical response in individuals with ASD was due to over-sensitivity to the local motion signals. This experimental paradigm showed atypical local motion processing of BM in individuals with ASD. (C) 2014 Elsevier Ltd. All rights reserved.

Objective: Developmental dyslexia (DD) is a neurodevelopmental disorder that is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. The magnocellular deficit theory is one of several hypotheses that have been proposed to explain the pathophysiology of DD. In this study, we investigated magnocellular system dysfunction in Japanese dyslexic children.
Methods: Subjects were 19 dyslexic children (DD group) and 19 aged-matched healthy children (TD group). They were aged between 7 and 16 years. Reversed patterns of black and white sinusoidal gratings generated at a low spatial frequency, high reversal frequency of 7.5 Hz, and low contrasts were used specifically to stimulate the magnocellular system. We recorded visual evoked potentials (VEP) from the occipital area and examined their relationship with reading and naming tasks, such as the time to read hiragana characters, rapid automatized naming of pictured objects, and phonological manipulation.
Results: Compared to the TD group, the DD group showed a significantly lower peak amplitude of VEPs through the complex demodulation method. Structural equation modeling showed that VEP peak amplitudes were related to the rapid automatized naming of pictured objects, and better rapid automatized naming resulted in higher reading skills. There was no correlation between VEP findings and the capacity for phonological manipulation.
Conclusions: VEPs in response to the magnocellular system are useful for understanding the pathophysiology of DD. Single phonological deficit may not be sufficient to cause DD.

Accepted, ISSN 0387-7604

Background: Psychometric properties of The Japanese version of Swanson, Nolan, and Pelham IV scale (SNAP-IV)-Teacher Form were examined in this study. Method: Community samples of 1296 children (Grade 1-9, boys 52.9%) were collected from public elementary/middle schools in suburban areas. Teachers rated their children's behavior using Japanese version of SNAP-IV-Teacher Form and Strength and Difficulties Questionnaire (SDQ). Results: A three-factor structure model, which was equivalent with AD/HD symptoms subscales (inattention, hyperactivity/impulsivity) and oppositional-defiant disorder symptoms subscale was obtained and confirmed in an explorative/confirmative factorial analysis (Goodness-of-Fit Index = 0.913, Comparative Fit Index = 0.959, root mean square error of approximation = 0.056). The current version of the SNAP-IV-Teacher Form demonstrated good test retest reliability (intra-class correlation = 0.752-0.822), high internal consistency (Cronbach's a = 0.933-0.952), significant correlations with relevant subscales of Japanese version of SDQ, and typical effects of age and gender on those subscales. Conclusion: The current study indicates that the Japanese version of SNAP-IV-Teacher Form is a reliable and valid instrument for rating symptoms related to AD/HD and ODD.
