During an experiment on infant behavior, it was observed that young children shared toys with their mothers; therefore, a series of research studies was designed to investigate this phenomenon. The general purposes of the research were: (1) to define sharing more precisely and develop objective measures of frequency and duration for it, (2) to…

Three mothers of handicapped children were taught to imitate their child's behavior; subsequently the number of mands displayed by the mothers during play sessions were measured. Results showed increases in the percentage of sample intervals during which mothers imitated their children and showed that, as imitations increased, mands decreased.…

This study examined (1) the level of symbolic capability as revealed in play, (2) the use of spontaneous vocal imitation, and (3) the nature of certain classes of words occurring in spontaneous infant language.
