Objective
. Little ones differ in the extent to which they enjoy the added benefits of maternal delicate care or put up with the adverse implications of insensitive care, and these variances can be accounted for by biological features. Having said that, how prone kids adapt to maternal sensitivity in strategies that both increase optimistic progress or guide to maladjustment has still to be established. Below, we propose a novel model of socioemotional mechanisms by which the joint influences of maternal sensitivity and youngster biological features affect youngster adjustment. Design . We propose a theoretical model, in which children’s vagal functioning and polymorphisms in serotonin transporter (5-HTTLPR) and dopamine receptor D4 (DRD4) genes confer susceptibility to the results of maternal sensitivity on internalizing, externalizing, prosocial and moral habits via variations in interpersonal methods for emotion regulation, the threat reaction program, and empathy. Results . Theoretical and empirical aid for the proposed mechanisms are delivered. Conclusions . The proposed mechanistic model of susceptibility to maternal sensitivity offers a novel framework of for whom and how kids are afflicted by early maternal care, highlighting multiple reciprocal, interacting influences across genes, physiology, habits, and the natural environment.
