Question

Quizplus · Accepted Answer

The Bayley Scales of Infant Development II is considered the most psychometrically sound test of infant ability available to date, as it has strong reliability and validity evidence supporting its use in assessing cognitive, motor, and social-emotional development in infants aged between one month and 42 months. The Brazelton Neonatal Assessment Scale is typically used to assess the behavior of newborns in the first few weeks of life, but it is not considered a comprehensive ability test. The Gesell Developmental Schedules and Cattell Infant Intelligence Scale are outdated measures of infant development that are no longer commonly used in clinical or research settings.
