ABSTRACT
In the last few years, a great deal of research has focused on the use of joint attention by the infant and young child. For the most part, this research has examined normative patterns of development. Less attention has been paid to individual differences within typically developing groups or to differences due to developmental delay or psychopathology. Yet, children vary in their ability to regulate attention, their levelof social understanding, and their interest in the reactions of other people. For this reason, it seems worthwhile to investigate the extent to which individuals differ and how these differences might be related to cognitive and language development.
