ABSTRACT
"The infant comes into the world with inherited potential provided always that it is accepted that the inherited potential of an infant cannot become an infant unless linked to maternal care". The infant comes to the customs barrier, which is birth, accompanied by "a sum of inherited features and inborn tendencies toward growth and development". The experiments, which date from the late seventies, are essential and give food for thought on the capacity of the child for creative perception of the world. The cognitive capacities are also found in the ability of the infant to correlate intensive light and intensive sound, sound patterns and time patterns, and so on. The infant then finds himself faced with the huge task of having to decode signals that are often incoherent, often contradictory, between the "gesture which says something" and the "word that he feels".
