Existing psychophysiological measures (fMRI, EEG) are impractical for a large-scale behavioral study due to their exor-bitant data acquisition cost. Psychological tests (Stroop task) are economical but are too coarse to inform dynamic interac-tions among perceptual, cognitive, and affective processes. By augmenting standard cognitive tests with choice-reachingmeasures, the complex interaction of motivation, action and cognition can be examined by analyzing the movement of thecomputer cursor pixel by pixel. Open source software and R library mousetrap help researchers to collect mouse-cursortrajectory data easily. With continued interest and innovation, the mouse-cursor trajectory method is likely to become astandard procedure for psychological tests, especially for the study investigating individual differences underlying cog-nitive, affective, and perceptual processing (Xiao & Yamauchi, 2014; Yamauchi et al., 2015; Yamauchi & Xiao 2017;Leontyev, Sun, Wolfe, & Yamauchi, 2018).
