Let's break down what's being asked and evaluate the answer choices in light of typical infant cognitive development milestones.
Option 1: 'invisible displacement' — This term refers to tracking an object that has been moved out of sight without being seen, which is a more advanced concept typically associated with later stages of object manipulation and is not the main milestone illustrated by a baby not searching when the toy is hidden. Thus, this is not the best fit for an 8-month-old learning phase.
Option 2: 'object permanence' — This is the understanding that objects continue to exist even when they are not visible. At about 8 months, infants are beginning to develop this skill, and failure to search when a toy is hidden behind the sister’s back suggests the infant has not yet fully grasped that the object still exists out of sight. This aligns well with the described behavior.
Option 3: 'infantile amnesia' — This refers to the inability of most people to recall memories from very early childhood, typically before ages 2–4. It is related to autobiographical memory rather than a basic understanding of whether hidden objects still exist. It does not explain Isaiah’s behavior in the scenario.
Option 4: 'deferred object awareness' — This term is not a standard or widely used label in developmental psychology for explaining early infant cognition about hidden objects. It sounds nonstandard and does not match the classic milestone described by the scenario.
In summary, the scenario directly tests whether the infant has grasped that an object continues to exist when out of sight, which is the concept of object permanence. The other options either describe more advanced (or unrelated) ideas or are not established concepts for this context.
