AP PSYCHOLOGY

Detailed explanation-1: -Things like smiling and responding to you, making eye contact or calming down when held by a familiar adult are all social and emotional milestones that most babies express and explore by a certain age.

Detailed explanation-2: -Infant smiles appear to be direct behavioral expressions of joyful feelings (see Figure 1). This apparent link between behavior and meaning has motivated over a century of research on the emotional significance, causes, behavioral correlates, and developmental consequences of early smiling.

Detailed explanation-3: -Infants (birth to 24 months of age) can express a wide range of basic emotions including: discomfort, pleasure, anger, fear, sadness and excitement. As we learned in Chapter 6, infants are developing attachments to primary caregivers and may show some anxiety when separated from the important adults in their lives.

Detailed explanation-4: -Babies may flap their hands or arms because they are excited or happy. Since they do not yet have the verbal skills to express their emotions, flapping is a physical way to show how they’re feeling.
