Food transfer is considered to provide infants with additional nutrients during weaning, and in fact, its frequency peaks around this time. However, the mechanisms underlying such food transfer remain unclear. In this study, we investigated whethe...

This study investigated whether 12 participants with color-vision deficiency had Superior Visual discrimination of color-camouflaged stimuli shown on a computer screen compared with 12 participants with normal trichromatic vision. Participants wer...

Due to a middle- to long-wavelength-sensitive (M/LWS) cone opsin polymorphism, there is considerable phenotypic variation in the color vision of New World monkeys. Many females have trichromatic vision, whereas some females and all males have dich...

Color-vision polymorphism in New World monkeys occurs because of an allelic polymorphism of the single-copy red-green middle-to-long-wavelength-sensitive (M/LWS) opsin gene on the X chromosome. Because color-vision types can readily be estimated f...
We determined the structures of long (L)-wavelength-sensitive and middle (M)-wavelength-sensitive opsin gene array of 58 male chimpanzees and we investigated relative sensitivity to red and green lights by electroretinogram flicker photometry. One...
This article reviews parental behavior and its endocrinological mechanisms in marmosets and tamarins, both cooperative breeders in the callitrichid family, and compares these findings with studies of macaque monkeys. The paper examines the similar...
親の養育態度と子の社会性の発達との関連は多くの先行研究で示されており、親の養育態度を定量的に測定することは発達研究において非常に重要である。本研究では,Robinson et al. (1995) の養育スタイル尺度をもとに、日本語版養育態度質問紙を作成し、内的一貫性を検討、因子構造を明らかにした。また、親を対象にした質問紙により測定された、子の向社会性、問題行動との間に予測された有意な相関関係がみられ、構成概念妥当性も確認された。
