Describe each of the five Bayley-III scales.
On Sep 22, 2024
The Bayley-III consists of five scales: three consisting of infant responses and two of parent responses. The Motor Scale measures gross and fine motor skills, such as grasping objects, drinking from a cup, sitting, and climbing stairs. The Cognitive Scale includes items such as attending to a stimulus or searching for a hidden toy. The Language Scale examines comprehension and production of language, such as following directions and naming objects. The Social-Emotional Scale is derived from parental reports regarding behavior such as the infant's responsiveness and play activity. Finally, the Adaptive Behavior Scale is based on parental reports of the infant's ability to adapt in everyday situations, including the infant's ability to communicate, regulate his or her emotions, and display certain behavior.
