Thorndike's Experiments

Early 20th-century experiments conducted by Edward Thorndike focusing on learning and behavior in animals, leading to the formulation of the law of effect.

Classical Conditioning

A learning process that occurs when two stimuli are repeatedly paired: a response which is initially elicited by the second stimulus is eventually elicited by the first stimulus alone.

Conditioned Response (CR)

The learned reaction or response to a previously neutral stimulus, after the stimulus has been repeatedly presented along with an unconditioned stimulus.

Unconditioned Stimulus (US)
