Ruth, an infant, sucked everything that touched her lips and also sucked nearby objects. A few months later she learned that certain objects such as her mother's breasts or a milk bottle can be sucked but other objects such as spoon, her toys, or her blanket cannot be sucked. In the context of Jean Piaget's theory of infant development, the cognitive process most likely responsible for Ruth's actions

A. coordination and internalization
B. assimilation and accommodation
C. habituation and dishabitutation
D. Equilibration and organization

B. assimilation and accommodation

Explanation:

Assimilation is the process by which infants incorporate new information into existing schemas. Infants are constantly assimilating new information either by experience or by learning. Assimilation is a lifelong process and is not restricted to children alone. Accommodation on the other hand involves the reshaping of already existing knowledge. For example, a child may think that all four legged creatures are goats, with time he learns to restrict the word goat to a specific four legged animal, this is accommodation.

Assimilation and accommodation are responsible for Ruth's ability to differentiate between materials that she can suck and not suck with time. Accommodation of knowledge has enabled her to lead what is edible and what is not.
