The effects of maternal behavior on the emotion regulation of 6- and 12-month-old infants

Research master thesis | Developmental Psychopathology in Education and Child Studies (research) (MSc)

Problems with emotion regulation in childhood are related to negative child outcomes later in life, such as behavior problems. Because parents play an essential role by assisting their infant to develop the ability to regulate their emotions, the purpose of this study was to gain deeper understanding of the relation between maternal behavior and infants’ behavioral and physiological emotional reactivity and emotion regulation. 66 mother-infant dyads participated in two stress paradigms: the still-face paradigm was conducted at 6 months of age and the child was exposed to the robot paradigm at 12 months of age. During the stress paradigms infants’ behavioral reactivity, self-soothing behavior, heart rate and respiratory sinus arrhythmia (RSA) were examined. Maternal sensitivity and maternal intrusiveness were observed during a free play task at the 6-month appointment. Overall, the infants showed behavioral and physiological arousal and regulation during stress.

Because parents play an essential role by assisting their infant to develop the ability to regulate their emotions, the purpose of this study was to gain deeper understanding of the relation between maternal behavior and infants’ behavioral and physiological emotional reactivity and emotion regulation. 66 mother-infant dyads participated in two stress paradigms: the still-face paradigm was conducted at 6 months of age and the child was exposed to the robot paradigm at 12 months of age. During the stress paradigms infants’ behavioral reactivity, self-soothing behavior, heart rate and respiratory sinus arrhythmia (RSA) were examined. Maternal sensitivity and maternal intrusiveness were observed during a free play task at the 6-month appointment. Overall, the infants showed behavioral and physiological arousal and regulation during stress. Although no effect of maternal intrusiveness was found, the 6-month-old infants of mothers judged as more sensitive showed more emotional reactivity, indicated by a greater increase in negative affect and heart rate than infants of less sensitive mothers. These infants also showed more physiological regulation, indicated by a greater decrease in RSA during stress than infants of less sensitive mothers. The stability of emotional reactivity and emotion regulation between 6 and 12 months was low: only the difference in RSA from stress to recovery was modestly stable. It is concluded that maternal behavior has an effect on the development of infants’ emotional reactivity and emotion regulation Future studies should further investigate the environmental characteristics influencing the development of emotion regulation in children using longitudinal designs.Show less
