INTEGRATING PROCESS OF COMMUNICATIVE MODE IN DEMANDING SITUATION DURING PREVERBAL PERIOD

Abstract

Three infants were observed for seven months during their preverbal period, and their developmental changes in form of communicative expression in a demanding situation were analyzed. They integrated their behavioral use of demanding an object, looking at a person and simultaneously vocalizing as soon as or shortly after they acquired the ability to the use of “pointing”. In consequence, the observation suggested that acquisition of “pointing” in a preverbal period coincided with the establishment of a developmental basis in intentional operation of multiple sensory modalities.
