There is extensive disagreement as to whether preverbal infants have conceptual categories for different emotions (e.g., anger vs. disgust). In addition, few studies have examined whether infants have conceptual categories of emotions "within" the same dimension of valence and arousal (e.g., high arousal, negative emotions). The current…

Accurate perception of emotional (facial) expressions is an essential social skill. It is currently debated whether emotion categorization in infancy emerges in a "broad-to-narrow" pattern and the degree to which language influences this process. We used an habituation paradigm to explore (a) whether 14- and 18-month-old infants perceive…

The meaning, mechanism, and function of imitation in early infancy have been actively discussed since Meltzoff and Moore's (1977) report of facial and manual imitation by human neonates. Oostenbroek et al. (2016) claim to challenge the existence of early imitation and to counter all interpretations so far offered. Such claims, if true, would have…

Adults often attribute internal dispositions to other people and down-play situational factors as explanations of behavior. A few studies have addressed the origins of this proclivity, but none has examined emotions, which rank among the more important dispositions that we attribute to others. Two experiments (N = 270) explored 15-month-old…

A laboratory procedure was developed for assessing imitation in the second year of life. Results demonstrate that 14- and 24-month-olds can imitate a simple action with an unfamiliar object, both immediately and after a 24-hour delay. Implications for research design and theory of infant memory are discussed. (RH)

Fourteen-month-old infants saw an object hidden inside a container and were removed from the disappearance locale for 24 hr. Upon their return, they searched correctly for the hidden object, demonstrating object permanence and long-term memory. Control infants who saw no disappearance did not search. In Experiment 2, infants returned to see the…

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Two studies assessed the gaze following of 12-, 14-, and 18-month-olds. Findings indicated that infants at all ages looked at the adult's target more when the adult turned to the target with open eyes than when the adult turned with closed eyes. Additional evidence suggested that infants were not simply responding to adult head turning, but were…
