Which term best describes a genetically inherited sequence of actions that, once triggered, runs to completion?

• A. Imprinting
• B. Fixed action pattern
• C. Habituation
• D. Operant conditioning

Answer: (B)

A fixed action pattern is an instinctive, genetically encoded sequence of behavior that, once triggered by the right cue, runs to completion. This pattern is relatively rigid and species-specific, and the initiating cue—often called a sign stimulus—activates the neural wiring built into the organism. Because it’s inherited, individuals of the species perform the same sequence in a consistent order. Imprinting involves learning during a critical period and isn’t a pre-programmed sequence. Habituation is a simple decrease in response to a repeated stimulus, not a fixed sequence of actions. Operant conditioning is about learning through consequences, shaping behavior rather than executing an inherited, complete motor sequence.
