Infant–parent attachment and lie-telling in young children: The Generation R Study

Insecure-attached adults are more likely to lie. However, it is unknown whether infant-parent attachment quality relates to lie-telling in early childhood. As in adults, lie-telling in early childhood might be related to attachment insecurity. However, a competing hypothesis might be plausible; lie-telling might be related to attachment security given that lie-telling in early childhood is considered an advancement in social-cognitive development. The current study is the first to investigate the link between insecure/secure and disorganized/non-disorganized attachment and lie-telling behavior in early childhood. Because lie-telling is studied in the context of cheating behavior, the association between cheating and attachment is additionally explored. A total of 560 Dutch children (287 girls) from a longitudinal cohort study (Generation R) were included in the analyses. Attachment quality with primary caregiver (secure/insecure and disorganized/non-disorganized attachment) was assessed at 14 months of age in the Strange Situation Procedure, and cheating and lie-telling were observed in games administered at 4 years of age. The results demonstrated no relationship of attachment (in)security and (dis)organization with cheating and lie-telling. Results are interpreted in light of evidence that lie-telling in early childhood is part of normative development. Limitations are discussed, including the time lag between assessments, the fact that lie-telling was measured toward a researcher instead of a caregiver, and the conceptualization of attachment in infancy versus adulthood. Attachment quality does not affect early normative lie-telling, but how and when it may affect later lying in children remains to be explored.
