Child and maternal attachment predict school-aged children's psychobiological convergence

Area of Science:

• Developmental psychology
• Attachment theory
• Psychophysiology

Background:

• Psychobiological convergence, the alignment of self-reported and physiological reactivity, is a correlate of attachment representations.
• Previous research has not explored this convergence in relation to children's self-reported attachment, parental attachment, or cardiovascular reactivity.

Purpose of the Study:

• To investigate the association between psychobiological convergence and children's self-reported attachment.
• To examine the role of parental attachment in this relationship.
• To explore the link with cardiovascular reactivity, specifically respiratory sinus arrhythmia (RSA).

Main Methods:

• A diverse community sample of 104 mothers and school-aged children (average age 10.31) participated.
• Children underwent a stressor task to measure subjective and physiological reactivity (RSA).
• Maternal and child attachment were assessed.

Main Results:

• A positive link between cardiovascular (RSA) and subjective reactivity was found only in children with high security.
• This convergence was also significant for children of mothers with low attachment avoidance and anxiety.
• These findings highlight the importance of secure attachment and low parental avoidance/anxiety.

Conclusions:

• The convergence of children's subjective and physiological responses to stressors is a developmental competence.
• This convergence may be foundational for developing effective coping strategies.
• Secure attachment and low parental attachment insecurity are associated with better psychobiological regulation.
