The authors undertook the present study to determine whether under ecologically valid, low-stress conditions, female and male neonates could be differentiated on cuddliness. Sixteen female and 15 male neonates were videotaped interacting briefly with both a female and a male adult who were blind to the sex of the neonate. Raters coded degree of cuddliness and activity level. Results showed that raters could discriminate the sex of the neonate on the basis of degree of cuddliness. Discussion focuses on the importance of theoretical and methodological considerations in assessing sex differences in behavioral characteristics of neonates.
directors of the nursery schools; and all the girls and boys and teachers who allowed us into their classrooms so that we might carry out this project. Finally, special thanks to Beth Landau and Julie Parsons, who served as research assistants at the schools and to Shari Aikins who helped with coding of the videotapes. q 1997 The International Society for the Study of Behavioural DevelopmentThis study was designed to examine the hypothesis that girls' expression of their own perspectives would decrease as the ratio of girls to boys decreased. In each of 12 classes, two target girls were observed in three contexts: with four other girls (all-girls group), with two other girls and two boys (girls-in-majority group), and with four boys (girls-in-min ority group). The number and duration of episodes in which the target girls clearly took a differing perspective from another child were analysed across the three contexts. Results showed a signi cant decrease in duration of episodes of rmly taking a different perspective from the all-girls to the girls-in-major ity contexts. However, there was no difference in duration of episodes of rmly taking a different perspective between the all-girls and the girls-in-mino rity contexts. In contrast to previous literature, ndings strongly suggest that girls' expression of their own perspectives is in uenced by several mechanisms and not simply the ratio of girls to boys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
