Infant gaze, head, face and self-touch at 4 months differentiate secure vs. avoidant attachment at 1 year: a
Insights
Four-month-old infants later classified as avoidant (A) attachment showed distinct behaviors, including less focused visual attention and more self-soothing, compared to secure (B) infants, indicating early predictors of attachment style.
Area of Science:
- Developmental Psychology
- Infant Behavior
- Attachment Theory
Background:
- Early infant behavior can predict later attachment security.
- Understanding early interaction patterns is crucial for identifying potential developmental trajectories.
Purpose of the Study:
- To determine if 4-month-old infant behaviors predict 1-year attachment classifications (secure vs. avoidant).
- To analyze specific infant behaviors during face-to-face interaction as early indicators.
Main Methods:
- Second-by-second coding of infant gaze, head orientation, facial expression, and self-touch/mouthing behaviors at 4 months.
- Classification of infant attachment (secure/avoidant) using the Ainsworth Strange Situation at 12 months.
- Markovian transition matrices to analyze behavioral sequences and coordination.
Main Results:
- Infants later classified as avoidant (A) spent less time in focused visual attention on the mother compared to secure (B) infants.
- Avoidant infants' focused attention was matched to secure infants only when accompanied by self-touch/mouthing.
- Head/gaze coordination differed: associated with self-touching in avoidant infants and positive affect disrupted coordination in avoidant infants.
Conclusions:
- Distinct behavioral patterns at 4 months can differentiate infants who will later show avoidant versus secure attachment.
- Early infant self-touch/mouthing and facial behavior variability are potential markers for attachment.
- These findings highlight the importance of early dyadic interactions in shaping attachment security.
Abstract:
The study attempted to distinguish avoidant vs. secure infants at 1 year from 4-month infant behavior only, during a face-to-face play interaction with the mother. Thirty-five 4-month-old infants were coded second by second for infant gaze, head orientation, facial expression and self-touch/mouthing behavior. Mother behavior was not coded. At 1 year, 27 of these infants were classified as secure (B), and 8 as avoidant (A) attachment in the Ainsworth Strange Situation. Compared with the B infant, the future A infant spent less time paying 'focused' visual attention (a look of a minimum 2 seconds duration) to the mother's face. Only if the A infant engaged in self-touch/mouthing behavior did its focused visual attention match that of the B. Markovian t to t+1 transition matrices then showed that both for future A and for future B infants, focused visual attention on the mother constrained the movements of the head to within 60 degrees from center vis-à-vis, defining head/gaze co-ordination within an attentional-interpersonal space. However, infant maintenance of head/gaze co-ordination was associated with self-touch/mouthing behavior for the A infant but not the B. Positive affect was associated with a disruption of head/gaze co-ordination for the A but not the B. Whereas the B had more variable facial behavior, potentially providing more facial signaling for the mother, the A had more variable tactile/mouthing behavior, changing patterns of self-soothing more often. Thus, infants classified as A vs. B at 12 months showed different behavioral patterns in face-to-face play with their mothers as early as 4 months.
