Simple Reaction Time
The Research Instructor conducted an experiment about Simple Reaction Time. The Subject hold the timer while the Experimenter gave a go signal, and the Subject started the timer and shared stories. The Recorder used a cell phone to track the time. The Subject was not able to see the timer, and also the data that was being recorded. This was performed forty-five trials. Afterwards, the Experimenter and the Subject switched roles and performed ten trials for the second subject. The Subject having forty-five trials had the tendency to have more “12 seconds” time target because she had a lot of trials. It was more accurate than the Subject having ten trials. Without the “free association”, the Subject tends to hit more “12 seconds” time target because she’s more focused than having “free association”. Objective
To acquaint the students in reading laboratory primers and organize data into summaries and graphs. Background
Simple Reaction Time is the time required for a subject to initiate a prearranged response to a defined stimulus. It is also a test which measures simple reaction time through delivery of a known stimulus to a known location to elicit a known response. The only uncertainly is with regard to when the stimulus will occur, by having a variable interval between the trial response and the onset of the stimulus for the next trial. (Retrieved from http://www.camcog.com/simple-reaction-time.asp) Like Choice Reaction Time it is useful for testing general alertness and motor speed, and is often sensitive. Ludwig Lange, working in Wundt’s Institute at Leipsic in 1886-7 found that the duration of the simple reaction was appreciably different, according as the reagent directed his attention (so far as possible) exclusively upon the sense-impression or upon the movement to be made in response to it. Lange accordingly distinguished two types or forms of simple reaction, the sensorial and the muscular....
