Relations between behavioral characteristics of infants, their mothers' behaviors, and performance on the Bayley Mental and Motor Scales.
Bayley Mental scores were significantly related to several concurrent ratings of infant and maternal testroom behavior when firstborn black male infants were 14 months (N equals 49), 18 months (N equals 34), and 22 months of age ( equals 32). With increasing age, social responsiveness played a relatively less important role in successful performance, while object responsiveness became increasingly important. Bayley Motor scores were related to many fewer ratings than the Mental scores. Gross Muscle Coordination was related to performance at all three ages, and Energy ratings at two of the three ages. For both the Mental and Motor scores, fewer relationships were observed at the 18-month testings as compared to the 14 and 22-month testings. By 22 months, infants scoring higher on the Bayley Mental scale had mothers who were more highly involved with their child's achievement as judged by testroom behaviors.
