Document Summary
3 stage model of information processing: response selection stage. Once stimulus is identified, the appropriate action must be selected. To brake or swerve to avoid a parked car . Deciding what plan on action you are going to take. Utilize/ support neural circuitry from the frontal lobe. We have to enter and fully complete stimulus identification in order to reach response selection: number of stimulus response alternatives, stimulus compatibility. Increasing the number of alternatives relevant to a response increases the time required to process and select an appropriate response. In discriminant reaction time = only one task is important. Choice reaction time = each light associated with its own response. As we add stimulus response alternatives, reaction time increases. Example 1: left - 2 lights, 2 responses. Example 2: right 4 lights, 4 responses. Looking at sra alternatives and how reaction time increased as we increased the sra. Reaction time increased by 150 milliseconds every time the sr alternatives doubled.
