The Effect of Stimulus Type on Reaction Time

Abstract
Previous studies on reaction time have examined the effects of different kinds of stimuli; this experiment specifically tests reaction time in response to auditory and visual stimuli. The common belief is that an auditory stimulus is faster than visual stimuli. There were 23 participants; 95% were Caucasian, with six males and 17 females. This experiment required participants to respond to either an auditory or visual cue by pressing a button. The data was measured by way of a stop clock. Using a two-tailed dependent t –test to analyze the data, it was found that the critical t was greater than the t obtained resulting in the retention of the

For the present study it was hypothesized that in a group of undergraduate college students with both male and female participants that are of the same age and around the same athletic ability that the reaction time would be significantly faster when the stimulus was audible and would be slower if the stimulus was visual. The purpose for this specific experiment is to test 1) reaction time when an auditory stimulus is given and 2) reaction time when a visual stimulus is given.
Method
Participants Participants were between the ages of 18 and 22 with one outlier. The mean age of participants was 19.5. There were 23 participants. They were 95% Caucasian, with six males and 17 were females. It was a convenience sample, from the Anderson University 2012 General Psychology Laboratory class.
Instruments
This experiment was conducted using a Visual Choice Reaction Time Apparatus from the Lafayette Instrument Company, model no. 63035A and a Response Panel, model no. 63035. The response panel has five buttons; four of the buttons corresponded to lights (red, white, green, and blue) and the fifth button corresponded to an audible buzzer tone. The only buttons that were used from the apparatus were the white light and the buzzer buttons; the other buttons were covered. The time was measured by a stop clock which was also created by the Lafayette Instrument Company, model
