graded competitive effects in a categorization task. Participants clicked one of two categories
(eg, mammal or fish) in response to atypical or typical exemplars (eg, whale or cat) in the
form of words (Experiments 1 and 2) or pictures (Experiments 3 and 4). Streaming x, y
coordinates of mouse movement trajectories were recorded. Normalized mean trajectories
revealed a graded competitive process: Atypical exemplars produced trajectories with …
