Mary is playing with her infant daughter Rose. Mary responds to Rose's facial expressions by mimicking and exaggerating the same expressions. All of a sudden Mary's face becomes blank and she does not show any emotion. How is Rose likely to respond?

It is normal for infants to manifest a series of behavior according to how others react. In the case of Mary and Rose, Mary is playing with her daughter and makes exaggerated expressions that seem to please Rose. When Mary suddenly stops doing them and puts herself in an attitude that is not funny to Rose, she may feel somewhat confused and not understanding can end up moving away from her mother.

While it is true that infants (depending on their age) may or may not understand expressions and their meanings, they react to when something makes them feel good and when it does not. An infant usually enjoys someone who makes exaggerated expressions and mimics, these gestures make him laugh. But if the infant is in a situation where exaggerated expressions change to the opposite, it may feel somewhat confusing and move away because it does not understand what has happened.
