The aim of this Final Year Project was to test the reaction time disparity that occurred when different visual references were given to participants who also received an audio referent of equal ease of comprehension. In order to achieve this, reaction times were measured between two audio sentences. One participant group were given a visual referent of a set of unambiguous pictures, while another were given an ambiguous set. When participants sat down in front of a laptop they pressed a button that brought up a series of pictures and simultaneously an audio track was played to them. As soon as they understood the audio track they pressed the button again and their reaction time was recorded. A significant difference was found between the two groups and the conclusion was arrived at that the ambiguous pictures allowed for easier comprehension of the audio track.
