Document Summary
Input stimulus identification response selection response programming output: we process information similar to a computer. Stages of information processing are serial and discrete. Particularly utilizes neural circuitry from the frontal lobe: we have to enter and full complete stimulus identification, response selection stage. Once stimulus is identified, the appropriate action must be selected. E. g. , to brake or swerve to avoid a parked car . Factors influencing response selection: the 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: with a choice reaction time each light is associated with its own response. Task: choice reaction time task, looking at sra alternatives and how reaction time increase as we increases the sra. Equation for a straight line: y = a + b(x) This equation can be adapted to compute a reaction time value in a choice rt task.
