Document Summary
Operant behaviors are controlled by their consequences; operant conditioning involves the manipulation of consequences. Respondent behaviors are controlled by antecedent stimuli and respondent conditioning involves the manipulation of antecedent stimuli. Carla works in a factory where each time the machine stamped the plastic on a toy, a short blast of air hit carla in the face. Carla began to blink each time the machine stamped a part. Carla noticed that she continued to blink even after but it went away after a few days. Carla"s blinking is an example of a respondent behavior, elicited by the antecedent stimulus of a blast in the air. Because the clicking sound came right before the blast air each time, carla"s blinking was conditioned to occur at the clicking sound. Certain types of stimuli elicit types of bodily responses. Infants engage in sucking responses when an object such a nipple touches their lips. The pupil of the eye constricts on exposure to bright light.
