Emotion socialization and expressive development in preterm and full-term infants

Area of Science:

• Developmental Psychology
• Infant Behavior Studies
• Maternal-Infant Interaction

Background:

• Examined expressive behaviors of full-term and preterm infants and their mothers.
• Focused on face-to-face interactions at 2.5, 5, and 7.5 months of age.

Purpose of the Study:

• To analyze developmental changes in infant emotional expression.
• To investigate maternal responsiveness to infant affect.
• To explore the directionality of influence in mother-infant emotional patterns.

Main Methods:

• Utilized second-to-second coding of videotaped interactions.
• Employed Izard's discrete emotion coding system.
• Analyzed changes in infant affect and maternal contingent responding over time.

Main Results:

• Infants showed increased positive affect (interest, joy) and decreased negative affect (pain) with age.
• Maternal contingent responding increased to infant interest and decreased to infant pain.
• Preterm infants exhibited anomalous maternal responses, including less facial imitation and random/ignoring responsiveness.

Conclusions:

• Infant emotional development is characterized by increasing positive and decreasing negative affect.
• Maternal responsiveness adapts to infant emotional cues, with specific challenges observed with preterm infants.
• Emotion socialization involves bidirectional influence, with infants learning from maternal modeling and contingency.
