What research did meltzoff and Moore do?

Meltzoff and Moore conducted pioneering research in the 1970s that focused on infant imitation. They found that infants as young as 12 to 21 days old could imitate facial expressions, such as sticking out their tongues or smiling, suggesting that this ability is innate rather than learned. Their work challenged previous notions about the cognitive capabilities of infants and provided evidence for early social interaction and communication skills. This research laid the groundwork for further studies in developmental psychology and the understanding of early human development.
