Temperament and attachment: one construct or two?

Area of Science:

• Developmental Psychology
• Child Psychiatry
• Behavioral Science

Background:

• Temperament and attachment are key constructs in understanding early social-emotional development.
• Previous research has explored the relationship between infant temperament and attachment security, with varying conclusions.

Purpose of the Study:

• To examine the distinct and overlapping contributions of temperament and attachment to child development.
• To clarify whether temperament influences the type or overall security of attachment relationships.

Main Methods:

• Review of existing literature on infant temperament and attachment.
• Analysis of studies investigating temperament dimensions (e.g., negative emotionality) and their association with attachment behaviors in the Strange Situation.

Main Results:

• Temperament dimensions, like negative emotionality, may correlate with specific infant behaviors during attachment assessments but do not predict overall attachment security.
• A constellation of temperament characteristics, rather than a single trait, might be more related to attachment security.
• Goodness-of-fit between infant and caregiver characteristics appears crucial for predicting attachment security.

Conclusions:

• Temperament and attachment are distinct but interrelated constructs, not interchangeable.
• Infant temperament likely influences attachment security indirectly, moderated by factors like caregiver personality and social support.
• A transactional model, considering both infant and caregiver characteristics, is essential for understanding early social-emotional development and attachment.
