Final answer:
Intelligence in infants can be measured using assessments like the Bayley Scales of Infant and Toddler Development and the Visual Recognition Memory task. Observations of problem-solving abilities and social interactions also provide insights into intelligence.
Step-by-step explanation:
Intelligence in infants can be measured through various methods and assessments. One commonly used assessment is the Bayley Scales of Infant and Toddler Development, which evaluates an infant's cognitive, language, and motor skills.
