From birth onward, infants show differential facial and bodily movements which coincide with specific emotions. Emotions such as joy, interest, anger, fear, disgust, and sadness emerge early. Not until the middle of the second year do infants express more complex emotions or what Darwin called self-conscious emotions; first embarrassment, and then shame, guilt, and pride. These new emotions depend on and emerge along with a new cognitive capacity, that of consciousness as measured by self-recognition, the beginning of symbolic play, and the emergence of personal pronouns such as me and mine . These capacities are likely supported by the maturation of particular brain regions.
