Learning Objective: L012 2-301 Discuss some of the important points of social competence and a baby’s ability to imitate behavior Answer: Research from the late 1970s suggests that babies are able to imitate a behavior modeled by an adult if the behavior is something that the infant already performed spontaneously Psychologist Tiffany Field reported that infants could discriminate between basic facial expressions, such as happiness, sadness, and surprise Subsequent research has disproved some of this in that it was found that babies could not demonstrate imitative skills consistently, 127 Copyright © 2012 by Pearson Education, Inc All rights reserved and that they could only produce a single imitative movement such as sticking out the tongue, which may actually be more of an exploratory action Aspects of newborns’ behavior act as forerunners for more formal types of social interactions when they grow and develop Pages: 87-88 Level: Difficult Type: Applied Module 2.3:
