Bayley Scales of Infant and Toddler Development™, Fourth Edition (Bayley™-4) assesses infant and toddler development across five scales: Cognitive, Language, Motor, Social–Emotional, and Adaptive Behavior. Assessment of the Cognitive, Language, and Motor domains is accomplished by administering structured items to the child, and engaging the caregiver to support responses where appropriate. The Social-Emotional and Adaptive Behavior scales are administered via caregiver questionnaire which allows them to share their own observations of the child’s abilities
5 Developmental Domains
Cognitive: Visual preference, attention, memory, sensorimotor, exploration and manipulation, concept formation
Language: Receptive and expressive language subtests
Motor: Fine motor and gross motor subtests
Social-Emotional: Communicating needs, self-regulation using emotional signals
Adaptive Behavior: Listening and understanding, talking, caring for self, relating to others, and playing
