Some Experimental Tools for Tracking Continuous Mental Trajectories
This chapter emphasizes the importance of identifying the time scale at which a given behavior exhibits detectably graded transitions from state to state. It covers a variety of experimental methods that either record outcome-based measures from delimited tasks, such as reaction time and speed-accuracy tradeoff; continuous measures from continuous tasks, such as tracking of rhythmic motor movement; or continuous measures from delimited tasks, such as eye-tracking and reaching. Special attention is paid to eye-tracking and computer-mouse tracking in cognitive tasks. It is argued that motor planning and motor movement itself, even just pressing a button in a computer-based task, is coextensive with the cognitive processing that guides it.
Keywords: experimental methods, temporal dynamics, reaction time, electrophysiology, computer-mouse tracking, eye movements, reaching movements
