 There are two additional Bayley-II Scales depend on parental report, including the Social-Emotional scale, which asks caregivers about such behaviors as ease of calming, social responsiveness, and imitation play, and the Adaptive Behavior scale which asks about adaptions to the demands of daily life, including communication, self-control, following rules, and getting along with others.The Bayley-III Cognitive and Language scales are good predictors of preschool mental test performance.These scores are largely used for screening, helping to identify the need for further observation and intervention, as infants who score very low are at risk for future developmental problems.
