Infant rhythms versus parental time: Promoting parent–infant synchrony

► Parent–infant synchronization is a major task in the first year of life. ► Secure attachment is one of the consequences of a good enough parent–infant synchronization. ► Prevention of disorganized attachment has become a key issue in early prevention studies. ► CAPDEP is a prevention study with a sample of 440 children from vulnerable families. ► Preliminary results shows a clear clinical effect in reducing attachment disorganization. Traditional psychoanalytic theories of early development have been put into question by developmental psychology, and particularly by attachment theory. Psychopathology appears to be more linked to interpersonal relationship problems rather than to intra-psychic conflict, as hypothesized in Freudian drive theory. Establishing synchrony between parent and infant is probably one of the major tasks of the first year of life. Attachment theory appears to be an effective paradigm to understand how caregiver responses to stressful infant situations give way to different regulatory strategies, which impact on the effectiveness of the stress buffer systems and its physiological impact on emotion and stress regulation. This paper underlines the importance of synchronization between infant and caregiver; it highlights the key concept of attachment disorganization and of its relationship with sustained social withdrawal as a defence mechanism and an alarm signal when synchronization fails, and underlines the importance of early interventions promoting parent–infant synchrony.
