Bs. Kisilevsky et al., THE STILL-FACE EFFECT IN CHINESE AND CANADIAN 3-MONTH-OLD TO 6-MONTH-OLD INFANTS, Developmental psychology, 34(4), 1998, pp. 629-639
Studies conducted in China examining cross-cultural differences in 3-
to 6-month-olds used the still-face paradigm. In each study, 20 infant
s were in the experimental group (normal, still-face, normal interacti
ons) and 20 in the control (3 normal periods). In Study 1, infants int
eracted with either their mother or their father; they looked and smil
ed less to the still-face of both parents. In Study 2, infants interac
ted with both their mother and a stranger, with order counterbalanced.
Experimental groups showed similar still-face effects to both adults.
The control group responded similarly to the stranger in both orders
but responded less to their mother when she interacted 2nd. The data w
ere compared with archival data from Canadian infants. Although Chines
e infants took longer to begin smiling, responding was similar in both
cultures, despite differences in mothers' behavior: Chinese mothers p
layed with the infants' arms; Canadian mothers played with the legs.
