Answer 1

Children who are born deaf and blind spontaneously develop normal facial expressions such as smiling and frowning, as the ability to produce and recognize these expressions is universal and innate.

Step-by-step explanation:

The question pertains to whether children who are born deaf and blind would spontaneously develop normal expressions of smiling, frowning, laughing, and crying, or learn these expressions through imitation or trial and error. Research by Paul Ekman and others has shown that the ability to produce and recognize facial expressions of emotions is universal, and even individuals who are congenitally blind exhibit the same facial expressions associated with emotions as sighted individuals. This suggests that the facial muscle activity involved in generating expressions is innate. Furthermore, Charles Darwin had suggested that the expression of emotions in humans is cross-culturally universal. Therefore, the statement that children who are born deaf and blind spontaneously develop normal facial expressions is factually accurate.
