Is reaction time representing different cognitive process than accuracy?
5 answers
Reaction time (RT) and accuracy in cognitive tasks may represent distinct cognitive processes. While accuracy is often used to gauge cognitive flexibility in children, RT provides a better index as they transition to school, suggesting a speed-accuracy tradeoff. Models differentiate between automated and controlled processing, indicating dual processing mechanisms underlying cognitive test performance. Studies on tactile perceptual decisions show that changes in accuracy and RT can be explained by alterations in sensory evidence accumulation and non-decision time, respectively. Meta-analyses reveal weak associations between RT and error costs, emphasizing the importance of considering individual differences in processing speed and caution in cognitive tasks. Therefore, RT and accuracy likely tap into different cognitive processes, with RT reflecting the speed of information processing and accuracy indicating the precision of decision-making.
