Question

Quizplus · Accepted Answer

The child's inability to understand that the amount of liquid remains the same, despite the change in shape, indicates a lack of the concept of conservation. This is a developmental milestone typically achieved around age 7. Option A, sense of object permanence, refers to the understanding that an object still exists even when it cannot be seen, and is typically achieved in infancy. Option C, capacity for habituation, refers to the ability to become accustomed to a stimulus over time, and is not directly related to this scenario. Option D, secure attachment, refers to the emotional bond between a child and their caregiver, and is not directly related to this scenario.
