Identify the example that best illustrates a critical period outside language development.

• A. Habituation to a familiar sound in adulthood
• B. Imprinting in birds
• C. Learning to ride a bicycle in old age
• D. Language acquisition in toddlers

Answer: (B)

A critical period is a limited time early in development when experiences have a powerful, lasting impact on behavior and abilities. Imprinting in birds is a classic example of this outside language development: after hatching, there’s a brief window when the young bird must be exposed to a caregiver or a suitable object, and this exposure leads to a lasting attachment and bonds that shape social behavior and survival. If imprinting doesn’t occur during that window, the attachment can fail to form and the bird’s later behavior can be affected. Other options don’t fit as well. Habituation to a familiar sound in adulthood isn’t tied to a restricted developmental window and reflects ongoing learning rather than a timed, biologically programmed period. Learning to ride a bicycle in old age can happen well outside early development, showing learning later in life rather than a critical period. Language acquisition in toddlers involves a sensitive period for language, but it centers on language itself, not a non-language domain.
