Abstract
Distress reaction and emotional self-regulation. The aim of this work was to study distress responses and self-regulation behaviors in maternal separation along the second year of life, identifying both endogenous (temperament, cognitive capacity) as well as exogenous (maternal regulation) factors which can influence these behaviors. Self-regulation strategies were effective in emotional state alteration, so a more autonomous strategies' use were associated to lower distress response, and a more rudimentary strategies' use were associated to higher distress one. On the other hand, while distress response showed a significant decrease with age, strategies' use didn't show significant changes. Finally, the variables analyzed in this work have explained successfully individual differences in distress response and self-emotional regulation.
