However, less research has focused on the association between attachment and preadolescents¡¯ self-regulation performance. In a sample of 120 children, aged 9¨C13, we administered questionnaires to assess trust in maternal support and anxious and avoidant attachment. In addition, mothers reported about their children¡¯s self-regulatory abilities, and children performed the Stop-Signal Task (SST). Consistent with predictions, correlation analyses revealed that a more insecure attachment relationship with mother was not only associated with less self-regulatory abilities as perceived by mother but also with preadolescents¡¯ lower self-regulation performance in the SST. Adding demographic variables as covariates to the analyses did not significantly alter these effects. The current multi-method study contributes to an increasing awareness of the importance of the quality of the mother¨Cchild relationship for children¡¯s self-regulation %K Attachment %K effortful control %K preadolescence %K self-regulation %K Stop-Signal Task %U https://journals.sagepub.com/doi/full/10.1177/0265407517742531
