Odd Man Out
The Odd-Man-Out Reaction Time examination not only measures one's reaction time, but also one's ability to distinguish differences among the stimuli. More specifically, the odd man out task involves comparing the proportion of distances: the distance between the one light which is further away than the others, and the two lights that are closer together. Therefore, the higher correlation between the Odd Man Out Reaction Time test and IQ versus the Choice Reaction Time test and IQ could be potentially explained in that it is more complex because it tests an individual's ability to rapidly perceive differences in relationships in comparison to the Choice Reaction Time Test, which would be considered a clear discrimination task.
