Effects of Labelled Gender on Vocal Communication of Young Women with 4-month-old Infants

Most of the previous studies analyzing the effect of gender label on adults' interactive behaviours with infants concluded that gender stereotypes affect adults' behaviours more than the actual behaviours or characteristics of the infants. These stereotypes and their ensuing behaviours would contribute to the differential socialization experiences of infants according to their gender. The objective of the present study was to investigate further the effect of gender label on adults' vocal communication with infants. Therefore, the prosodic and content features of the language addressed by young women to infants presented as girls and as boys were examined. Sixteen women were observed during two 5-minute sessions of face-to-face interaction with 3-to-4-month-old infants, one introduced as a girl, the other as a boy, in a counterbalanced order. Six girls and four boys served as stimuli. The number of utterances addressed to the infants, their duration and fundamental frequency, as well as the prosodic contour and the content of each vocalization were measured. Results indicated only one significant gender label effect: Women referred more frequently to infant's global motor activity when the infant was presented as a boy. This observation is congruent with other data. However, our results do not demonstrate a consistent pattern of gender label effect when women are talking to unfamiliar infants in such a context.
