Early acquisitions of trisomic‐21 and social reinforcement

Abstract

The Down's syndrome population presents a social quotient higher than its inteligence quotient, main characteristic of its personality and because of the pronounced hipotony suffered by them, principally in the first years of life.This report shows the results of a study carried out about differential acquisitions of two groups of trisomy-21 babies, depending on the social reinforcement used in an early stimulation program. We used as reward a social reinforcement with two variants: administered in physical interaction with the subject (Rl group) and without interaction (RNI group). According to the' obtained data, we proved an upper level of acquisitions in the group which had received the reinforcement in the interaction.
