Investigates preschool children's ability to discriminate and categorize facial expressions. Four sets of drawings of faces depicted expressions of joy, sadness, surprise, and anger. Each set of drawings contained a "standard" face as well as five choices from which to select a match. (Author/RH)

Results indicated that 7-month-olds discriminated among happy, interested, angry, and sad expressions.…

The visually impaired children were less able to recognize faces successfully but showed no disadvantage in discerning facial expressions such as happiness, anger, surprise, or fear.…
