Imada, Toshie; Carlson, Stephanie M.; Itakura, Shoji – Developmental Science, 2013
Accumulating evidence suggests that North Americans tend to focus on central objects whereas East Asians tend to pay more attention to contextual information in a visual scene. Although it is generally believed that such culturally divergent attention tendencies develop through socialization, existing evidence largely depends on adult samples.…

Imura, Tomoko; Adachi, Ikuma; Hattori, Yuko; Tomonaga, Masaki – Developmental Science, 2013
The shadows cast by moving objects enable human adults and infants to infer the motion trajectories of objects. Nonhuman animals must also be able to discriminate between objects and their shadows and infer the spatial layout of objects from cast shadows. However, the evolutionary and comparative developmental origins of sensitivity to cast…

Yamagata, Shinji; Takahashi, Yusuke; Ozaki, Koken; Fujisawa, Keiko K.; Nonaka, Koichi; Ando, Juko – Developmental Science, 2013
This twin study examined the bidirectional relationship between maternal parenting behaviors and children's peer problems that were not confounded by genetic and family environmental factors. Mothers of 259 monozygotic twin pairs reported parenting behaviors and peer problems when twins were 42 and 48¬†months. Path analyses on monozygotic twin…

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…

Matsui, Tomoko; Rakoczy, Hannes; Miura, Yui; Tomasello, Michael – Developmental Science, 2009
It has been repeatedly shown that when asked to identify a protagonist's false belief on the basis of his false statement, English-speaking 3-year-olds dismiss the statement and fail to attribute to him a false belief. In the present studies, we tested 3-year-old Japanese children in a similar task, using false statements accompanied by…

Adachi, Ikuma; Kuwahata, Hiroko; Fujita, Kazuo; Tomonaga, Masaki; Matsuzawa, Tetsuro – Developmental Science, 2009
In a previous study, Adachi, Kuwahata, Fujita, Tomonaga & Matsuzawa demonstrated that infant Japanese macaques (Macaca fuscata) form cross-modal representations of conspecifics but not of humans. However, because the subjects in the experiment were raised in a large social group and had considerably less exposure to humans than to…

Sekiyama, Kaoru; Burnham, Denis – Developmental Science, 2008
The McGurk effect paradigm was used to examine the developmental onset of inter-language differences between Japanese and English in auditory-visual speech perception. Participants were asked to identify syllables in audiovisual (with congruent or discrepant auditory and visual components), audio-only, and video-only presentations at various…

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…

Kuhl, Patricia K.; Stevens, Erica; Hayashi, Akiko; Deguchi, Toshisada; Kiritani, Shigeru; Iverson, Paul – Developmental Science, 2006
Patterns of developmental change in phonetic perception are critical to theory development. Many previous studies document a decline in nonnative phonetic perception between 6 and 12 months of age. However, much less experimental attention has been paid to developmental change in native-language phonetic perception over the same time period. We…
