I want to compare visual and auditory reaction times. First we will ask participants to press space when they see a specific picture between several pictures. Every picture will be shown for 2 seconds and the time will be calculated when that specific picture is shown till the participant press space in milliseconds. Please tell me that can I do it with a normal PC?(I don’t want the exact time, I just want to compare them.) and what function I should use to measure reaction time in milliseconds?
Thanks in advance
