چکیده
Sexual dimorphism in sociability has been documented in humans. The present study aimed to ascertain whether the sexual dimorphism is a result of biological or socio-cultural differences between the two sexes. 102 human neonates, who by definition have not yet been influenced by social and cultural factors, were tested to see if there was a difference in looking time at a face (social object) and a mobile (physical-mechanical object). Results showed that the male infants showed a stronger interest in the physical-mechanical mobile while the female infants showed a stronger interest in the face. The results of this research clearly demonstrate that sex differences are in part biological in origin. © 2000 Elsevier Science Inc. All rights reserved.

Arm postures and movements were coded from video recording and step width was calculated from force platform data. The results showed that arms were held in fixed postures during the first 10 weeks. A decrease in these fixed postures wa...

8 Six-month-old infants (N = 43) showed differences in the frequency of neutral/positive vocalizations 9 produced when exposed to a standard (parent gazes at infant) versus modified still-face condition (parent 10 gazes above infant). No significant differences in smiling, social gaze, negative affect, and fuss/cry 11 vocalizations were observed. © 2002 Published by Elsevier Science Inc. 12

This study investigated the associations of the quantity and quality of infant nondistress vocalization with maternal and infant social actions (smiling and gazing) during dyadic interaction. Thirteen infants and their mothers were observed weekly in a face-to-face interaction situation from 4 to 24 weeks. Results showed that the quantity (rate per minute) and quality (speech-likeness) of infan...

Research is presented suggesting that an implicit sense of self is developing from birth, long before children begin to manifest explicit (conceptual) self-knowledge by the second year. Implicit selfknowledge in infancy is rooted in intermodal perception and action. Studies are reported showing that at least from 2 months of age, infants become increasingly systematic and deliberate in the expl...
