For my PhD, I used mouse-tracking to study conflict during judgement and reasoning. Tracking participants’ cursor movements as they choose betweeen competing response options lets us infer how drawn they are towards each option over time.

This experiment applies this technique to a classic base-rate neglect paradigm. To show what mouse-tracking captures, I’ve set it to plot the cursor trajectory on screen after each trial, which is fun.
