Wright N, et al. - In this work researchers investigated if maternal sensitivity to distress, and other parenting characteristics, were associated with Callous-unemotional (CU) traits over the preschool period, and examined whether this was mediated via infant attachment status. The finding revealed contributions from both sensitivity to distress and positive regard to reduced CU traits. Thereby indicating that children's responsiveness to others’ emotions could be increased by their own mothers’ responsiveness to them and their mothers’ warmth. No evidence suggested that this was mediated via attachment status.
