Abstract: | This study examined 12‐ and 13‐month‐old infants' behavioral strategies for emotion regulation, emotional expressions, regulatory styles, and attachment quality with fathers and mothers. Eighty‐five infants participated in the Strange Situation procedure to assess attachment quality with mothers and fathers. Infants' behavioral strategies for emotion regulation were examined with each parent during a competing demands task. Emotion regulation styles were meaningfully related to infant‐father attachment quality. Although expressions of distress and positive affect were not consistent across mothers and fathers, there was consistency in infant strategy use, emotion regulation style, and attachment quality with mothers and fathers. Furthermore, infants who were securely attached to both parents showed greater consistency in parent‐oriented strategies than infants who were insecurely attached to one or both parents. Limitations of this study include the constrained laboratory setting, potential carryover effects, and a homogeneous, middle‐class sample. |
