Examined social labels first used for parents, differentiation of parents and others on the basis of labeling behavior, and overgeneralization of social labels in 71 infants ranging in age from 9 to 24 months. (JMB)

Examined seven-month-old infants' perceptions of happy and fearful facial expressions. Infants could generalize discrimination of expressions across male and female faces if first familiarized with happy faces. Infants tended to look longer at fear faces than at happy faces. Preferential responding was not specific to any individual face.…

Three experiments investigated seven-month-old infants' ability to discriminate the facial expressions of happiness and fear. (CM)

Examined influence of object labels and shape similarity on 16- to 21-month-olds' inferences. Found that infants generalized non-obvious property of unlabeled objects to test objects with highly similar shapes. For objects labeled with novel nouns, infants relied on shape similarity and shared labels to generalize properties. For objects labeled…

Examined whether the atypical pattern of brain activity found in infants of depressed mothers generalized to situations not involving the mother. Found that 13- to 15-month-olds of depressed mothers exhibited reduced left--relative to right--frontal activity during baseline and during interactions with mother and familiar experimenter. This…

Infants were tested for recognition and discrimination of expressions. Ten-month olds familiar with a mix of happy and surprised expressions demonstrated generalized discrimination of positive affect. Only after seven months does dependence on the presence of expression-specific features for affect recognition and discrimination diminish. (BC)
