Those changes impair the development of an important set of mental capacities that help children regulate their thoughts and feelings, and that
impairment makes it difficult later on for them to
process information and manage
emotions in ways that allow them to succeed at school.
Previous studies also showed that dismissing attachment correlated both with an
impairment of the ability to
process negative
emotions, particularly sadness (Strathearn et al., 2009), and to a proneness to inhibit negative affective responses (Leckman et al., 2004; Strathearn, 2006; Crittenden, 2008).
