PS261 Chapter Notes - Chapter 8: Stimulus Control, Discrimination Learning, Color Vision
Document Summary
Both thorndike and skinner recognized that instrumental responses and reinforcers occur in the presence of a particular stimuli; these stimuli can come to determine whether or not the instrumental response is performed. The stimulus control of behaviour is an important aspect of how organisms adjust to their environment. To investigate stimulus control of behaviour, we first have to know how to identify and measure it. Experiment first shows how to experimentally determine whether instrumental behaviour has come under the control of a particular stimulus; the stimulus control of instrumental behaviour is demonstrated by variations in responding (differential responding) related to variations in stimuli. **if an organism responds one way in the presence of one stimulus and a different way in the presence of another stimulus, its behaviour has come under control of those stimuli. Stimulus discrimination: differential responding in the presence of two or more stimuli.
