The Bayley In/ant Behavior Record [IBR] was given to normal and high-risk in/ants at 8, 12 and 24 months. Selected items of the IBR summarized by a Primary Cognition Composite score differentiated these groups at all ages, while an Extroversion Composite score differentiated the groups only at 24 months. Correlations between the Primary Cognition Composite score and concurrent Bayley Mental scores were reliable at each age, and the Primary Cognition Composite score, particularly at 12 months, was an efficient predictor of 2-year Bayley Mental performance. These results suggest the value of assessing test-taking behaviors in both normal and high-risk infant groups.
