Dataset for the article "The dynamics of grouping-induced biases in apparent numerosity revealed by a continuous tracking technique"

Folders "800ms", "500ms" and "200ms" contain the data for the tracking experiments, for the 800, 500 and 200 ms refresh rate respectively. Data in folders are organized as follows:

Column 1: time
Column 2: horizontal mouse position (in pixels) 
Column 3: change in number of lines (log2(actual/previous))
Column 4: change in numerosity
Column 5: numerosity 
Column 6: number of lines


Folders "2AFC CONNECTED" and "2AFC ISOLATED" contain the data for the two alternative forced choice experiments, in the connected and isolated conditions respectively. Data in folders are both organized as follows:


Column 1: test numerosity
Column 2:probe numerosity (fixed)
Column 3: response (0 = test judged lower than probe; 1 = test judged higher than probe)
Column 4: test/probe first (1 = test first; 2 = probe first)
Column 5: response time (s)
