Which term describes a complex behavior that is rigidly patterned and unlearned?

• A. Reflex
• B. Conditioning
• C. Learned behavior
• D. Instinct

Answer: (D)

Instinct is an inherited, complex behavior that appears without learning and follows a fixed, species-typical pattern. Because these actions are encoded in the genome and triggered by specific cues, individuals perform them in the same way even without prior experience. This contrasts with reflexes, which are simple automatic responses to a stimulus, and with learned behaviors or conditioning, which require experience and practice. So the description of a complex, unlearned, rigidly patterned behavior points to instinct.
