| Abstract: | The ability to perceive and interpret facial expressions of emotion improves throughout childhood. Although newborns have rudimentary perceptive abilities allowing them to distinguish several facial expressions, it is only at the end of the first year that infants seem to be able to assign meaning to emotional signals. The meaning infants assign to facial expressions is very broad, as it is limited to the judgment of emotional valence. Meaning becomes more specific between the second and the third year of life, as children begin to categorize facial signals in terms of discrete emotions. While the facial expressions of happiness, anger and sadness are accurately categorized by the third year, the categorization of expressions of fear, surprise and disgust shows a much slower developmental pattern. Moreover, the ability to judge the sincerity of facial expressions shows a slower developmental pattern, probably because of the subtle differences between genuine and non-genuine expressions. The available evidence indicates that school age children can distinguish genuine smiles from masked smiles and false smiles. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
