Abstract
A comparison of the habituation rate of two infant populations was performed: Ivory Coast and French 3-, 5-and 8-month-olds. The same age evolution of the habituation performance was observed, but no differences were found between the two cultures at any age. The African infant's lead in development as shown by infant tests is not observed with the habituation paradigm. If such data are confirmed, they will lead to the conclusion that the difference is more a motor than a cognitive one.
