A lack of object permanence would indicate that the child does not understand that objects continue to exist even when they are not visible, which is not directly related to the scenario described. Habituation refers to the process of becoming accustomed to a stimulus over time, and secure attachment refers to the emotional bond between a child and caregiver, neither of which are directly related to the scenario described.
