Question 2

Infants develop an understanding that objects that are out of sight still exist

This definition accurately captures the essence of object permanence, a critical cognitive milestone in infant development. It signifies the realization that objects continue to exist even when they cannot be seen.

A) Infants develop an understanding that objects that are out of sight still exist

This option correctly defines object permanence. It highlights a fundamental aspect of cognitive development, where infants learn that objects maintain their existence despite being hidden or not directly observable.

B) Infants develop a fear of unfamiliar objects

This option is incorrect as it describes a different aspect of infant behavior, specifically related to fear and anxiety towards new stimuli. It does not pertain to the cognitive understanding of object permanence.

C) Infants can work with objects without having prior experience

This choice is also incorrect. It suggests a capability unrelated to object permanence, focusing instead on the ability to manipulate or interact with objects based on experience rather than understanding their existence when out of sight.

D) Infants have a cognitive understanding that solid objects cannot move through each other

This option is incorrect as it describes a different cognitive concept related to the understanding of physical properties of objects rather than the concept of object permanence. It does not address the idea of unseen objects still existing.

Conclusion

The correct answer is definitively A, as it directly addresses the core concept of object permanence, which is crucial in the cognitive development of infants. All other options fail to align with this concept, focusing instead on different aspects of infant behavior and understanding. Thus, option A stands out as the appropriate definition.
