This article summarizes current approaches to analyzing and theorizing about overt behavior measures such as reaction times, accuracy, and manual reaching. However, it also highlights likely future developments for interpreting these measurements. For reaction times, the article presents Sternberg's classical stage approach and discusses interpretations of reaction time distributions. It touches on the relationship between accuracy and reaction times i.e., the speed-accuracy-trade-off and presents an emerging standard approach of combining accuracy and reaction time in a theoretical interpretation, the drift diffusion model. Finally, the article explains recent developments for utilizing manual reaching to assess the time course of the brain's cognitive processes.
