The purpose of this study was to examine the relationship between verbal and nonverbal indices of intelligence from an infant development scale given at approximately two years of age with scores on an expressive language test administered to the same children two years later. The questions this study sought to answer were: (1) is there a difference between the number of verbal and nonverbal items passed at 18-34 months by a group of normal children and a group of late talkers, (2) is there a significant relationship between correct verbal and nonverbal responses on an inf ant development test and scores on an expressive language test two years later in normal children and late talkers, (3) is there a significant relationship between correct verbal receptive items on an infant development test and scores on an expressive language test two years later in normal children and late talkers, and (4) is there a significant relationship between correct expressive responses on an infant development test and expressive scores two years later in the normal children and the group of later talkers.
