What aspect of intelligence does the Bayley Scales of Infant Development focus on?

The Bayley Scales of Infant Development are specifically designed to assess the development of infants and young children, focusing on several areas, including motor skills and language acquisition. This assessment evaluates both how well a child can perform tasks that require physical coordination and control, such as reaching or grasping objects, as well as their ability to understand and use language.

These scales are crucial during the early developmental stages when significant growth occurs in these areas. By measuring these skills, the Bayley Scales help identify any potential delays or developmental concerns, enabling early intervention if necessary. This focus on motor and language skills is fundamental in shaping a child's future learning and social interactions.

Other options like cognitive and social skills, emotional and behavioral development, and physical growth and nutrition, while important aspects of overall development, are not the primary focus of the Bayley Scales, which are specifically tailored to evaluate the developmental milestones in motor and language areas for infants and toddlers.
