In addition, the effect of maternal risk status on children’s emotional and behavioural development was examined. The sample consisted of 51 mothers and their 6-month-old infants. Measures of heart rate, pre-ejection period (PEP), skin conductance level (SCL), and respiratory sinus arrhythmia (RSA) were collected during baseline and during the SFP episodes. Infant behavioural responses were coded as well. The SFP was able to elicit sympathetic and parasympathetic activity. In response to the still-face an increase in sympathetic activity was found, but only by SCL and heart rate, not by PEP. In addition, the still-face elicited an inhibition of the parasympathetic nervous system, the RSA decreased and the heart rate increased. In the transition from still-face to reunion, an effect of risk status was found on the pattern of heart rate and SCL. Infants from the high-risk group showed more sympathetic activity, indicating more stress and less emotion regulation. Overall, the SFP is able to elicit physiological features of emotion regulation and is able to indicate early differences in the autonomic nervous system activity in response to stress. Future studies should replicate these findings and should further investigate the role of maternal risk status.Show less
