Reflexes, instincts, conditioned responses, and startle reactions are all rapid automatic responses to a stimulus. Reflexes are involuntary, unlearned responses to a specific stimulus, such as the knee-jerk reflex. Instincts are innate, unlearned behaviors that are performed in response to a specific stimulus, such as the suckling reflex in infants. Conditioned responses are learned associations between a stimulus and a response, such as the salivation response to the sound of a bell in Pavlov’s dogs. Startle reactions are sudden, involuntary responses to a sudden, unexpected stimulus, such as the flinching response to a loud noise.
