This study examined the similarities/differences between the social phenotypes of Williams syndrome (WS) and autism spectrum disorder (ASD). As cultural norms may affect symptom evaluation, this study administered the Social Responsiveness Scale-2 to Japanese individuals with WS (n = 78, 4.4-44.0 years) and ASD (n = 75, 4.7-55.4 years). The scores…

The purpose of the present study was to investigate associations of dietary intake including vitamin D, folate, and n-3 and n-6 polyunsaturated fatty acids (PUFA) in pregnant women with broad autism phenotype (BAP). The Japan Environment and Children's Study is a government-funded birth cohort study. All complete data of 92,011 were analyzed. The…

Dutton, Edward; Van der Linden, Dimitri; Madison, Guy – Journal of Creative Behavior, 2020
Previous research has attempted to understand why countries with relatively favorable conditions and high estimated average IQs (such as Finland and Japan) have a relatively low per capita number of scientific Nobel prizes. In the present study, we examine whether there is a relationship between national schizophrenia and left-handedness…

Sakamoto, Miki; Yamaguchi, Etsuji; Yamamoto, Tomokazu; Wakabayashi, Kazuya – International Journal of Science Education, 2021
Socio-scientific decision-making necessitates reasoning from multiple perspectives and the use of trade-offs. This study examines how students decide on socio-scientific issues when they engage in an instructional intervention to enhance their socio-scientific decision-making towards consensus building that, in this study, emphasises generating…

Suzuki, Tomoko; Miyaki, Koichi; Eguchi, Hisashi; Tsutsumi, Akizumi – Autism: The International Journal of Research and Practice, 2018
This study aimed to confirm whether autistic traits are normally distributed across a population and to describe their association with the sociodemographic characteristics of Japanese workers. The participants were 2075 workers aged 23-65 years from various parts of Japan. Autistic traits were measured using an abridged Japanese version of the…

Fujisawa, Keiko K.; Todo, Naoya; Ando, Juko – Infant and Child Development, 2017
Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is…

Kazama, Tomoko; Ogawa, Masakata – International Journal of Science Education, Part B: Communication and Public Engagement, 2015
Life exhibitions in Japanese science museums (SMs) face difficulties in coping with rapid progress in the life sciences owing to certain constraints around the frequency of exhibit renovations, and the Japanese indigenous understanding of the natural world (Shizen) that Japanese visitors unconsciously bring with them. To what extent do current…

Dorling, Danny; Tomlinson, Sally – Journal for Critical Education Policy Studies, 2016
The old myth about the ability and variability of potential in children is a comforting myth, for those who are uneasy with the degree of inequality they see and would rather seek to justify it than confront it. The myth of inherent potential helps some explain to themselves why they are privileged. Extend the myth to believe in inherited ability…

Fujisawa, Keiko K.; Ozaki, Koken; Suzuki, Kunitake; Yamagata, Shinji; Kawahashi, Ikko; Ando, Juko – Developmental Science, 2012
Although growth in head circumference (HC) during infancy is known to predict later childhood outcomes, the mechanisms underlying this association with later sociocognitive abilities remain undetermined. Thus, using a sample of 241 pairs of normally developing Japanese twins, this study investigated the underpinnings of the association between HC…

Fujisawa, Keiko K.; Wadsworth, Sally J.; Kakihana, Shinichiro; Olson, Richard K.; DeFries, John C.; Byrne, Brian; Ando, Juko – Learning and Individual Differences, 2013
This first Japanese twin study of early literacy development investigated the extent to which genetic and environmental factors influence individual differences in prereading skills in 238 pairs of twins at 42 months of age. Twin pairs were individually tested on measures of phonological awareness, "kana" letter name/sound knowledge,…

Lark, Amy; Richmond, Gail; Pennock, Robert T. – American Biology Teacher, 2014
New science standards and reform recommendations spanning grades K--16 focus on a limited set of key scientific concepts from each discipline that all students should know. They also emphasize the integration of these concepts with science practices so that students learn not only the "what" of science but also the "how" and…

This study focuses on two pre-reading strategies: vocabulary pre-teaching and comprehension question presentation. Researchers have claimed that a vocabulary strategy is less effective than any other pre-reading strategy. This study investigates whether their claim is true of Japanese university students. The purpose of the study is twofold. The…

Shikishima, Chizuru; Yamagata, Shinji; Hiraishi, Kai; Sugimoto, Yutaro; Murayama, Kou; Ando, Juko – Intelligence, 2011
It has been reported that the ability to solve syllogisms is highly "g"-loaded. In the present study, using a self-administered shortened version of a syllogism-solving test, the "BAROCO Short," we examined whether robust findings generated by previous research regarding IQ scores were also applicable to "BAROCO…

Using a behavioral genetic approach, we examined the validity of the hypothesis concerning the singularity of human general intelligence, the "g" theory, by analyzing data from two tests: the first consisted of 100 syllogism problems and the second a full-scale intelligence test. The participants were 448 Japanese young adult twins (167…

Zitzer-Comfort, Carol; Doyle, Teresa; Masataka, Nobuo; Korenberg, Julie; Bellugi, Ursula – Developmental Science, 2007
This study is concerned with ways in which children with Williams syndrome (WS), a rare neurodevelopmental disorder arising from a hemizygous deletion in chromosome band 7q11.23 including the gene for elastin (ELN) and approximately 20 surrounding genes, are affected by social mores of vastly differing cultures: the United States and Japan. WS…
