Mouse-tracking is said to provide a real-time record of decisionmaking in a conflict situation (Stillman, Shen, & Ferguson,2018); yet precise benefit of this method is unknown. Usingtwo versions of the attention network task (ANT-R) (Fan et al.,2009), we investigated the extent to which mouse movementmeasures capture cognitive conflicts created in flanker andSimon tasks. The movement measures collected in theaugmented ANT-R (mouse movement condition) wereresponsive to both flanker and Simon incongruency butresponse time and accuracy measures in the regular ANT-R(key-press condition) were responsive primarily to flankerincongruency only. The mouse movement measures were alsosensitive to interaction effects involving incongruency andgender, trial order and congruency sequence, while responsetime and accuracy in the regular ANT-R (key-press condition)were mostly insensitive to these interactions. These resultssuggest that mouse movement measures are more perceptive tocognitive conflicts.
