The ability to recognize familiar objects and people in the absence of sensory input is best described by the term "object permanence." This developmental milestone indicates that an individual understands that objects and people continue to exist even when they are not visible or perceptible through the senses. Object permanence is a crucial concept in cognitive development, demonstrating that a child can hold a mental representation of an object or person in their mind, facilitating memory and predictive skills.

In infants, this typically develops around 4 to 7 months of age, although the understanding can continue to evolve as they grow older. This foundational cognitive skill lays the groundwork for further learning and interaction with the environment, enhancing their ability to explore and engage with the world around them while also contributing to social relationships.

The other terms listed describe different concepts related to emotional and cognitive development. Separation anxiety pertains to the distress experienced by a child when a primary caregiver is not present. Stranger anxiety involves a child's apprehension towards unfamiliar individuals. Self-awareness refers to recognizing oneself as an individual separate from others and is a later developmental milestone. Each of these concepts is distinct and does not pertain to the recognition of familiar objects and people when not directly perceived.
