Question

Quizplus · Accepted Answer

Lilianne's fear of strangers and reaching for her mother when she sees someone unfamiliar indicates that she is likely in the sensorimotor stage of development, which ends around the age of 2. During this stage, infants develop a sense of object permanence, understanding that objects (including people) continue to exist even when they cannot be seen, heard, or touched. This cognitive milestone typically occurs before the development of conservation and overcoming egocentrism, which are associated with the later preoperational stage. The behavior described does not indicate a loss of secure attachment; rather, it suggests that Lilianne is seeking comfort and security from her primary caregiver in unfamiliar situations.
