Eye contact and social contingency experiences from 3 to 6 months of age and their relation to the detection of non-social contingencies

This longitudinal study focuses on the development of eye contact and the contingency of maternal reactions to infants' signals from the age of 3 to 6 months. Eighty-seven 3-month-old infants participated in this study. The amount of eye contact and of social contingencies experienced as prompt maternal responses was assessed micro-analytically based on videotaped mother – infant interactions. The ability to detect contingencies in non-social contexts was assessed by a visual expectation paradigm. The general pattern of the results shows decreases in eye contact and increases in contingencies during development, although this general pattern was not shown by all mothers. Furthermore, the results show that increases in the experience of early social contingencies are related to the ability to detect contingencies in the visual expectation task. The unexpected increase in maternal contingencies over time is discussed as reflecting a possible increase in the significance of association learning after the age of 3 months.
