Complete raw pecking data of all individual pigeons for each experiment.

Listed are the individual peck distances in cm relative to the location of the centre of rotation and relative to the corrected location of the centre of mass of the given dot stimulus where it was located 300 ms before the analysed peck occurred (see method section). For experiment 1b which used large 40 x 40 cm stimuli, the individual peck distances in cm relative to the screen centre are listed. Note that although the physical dimensions of the screen were 30.4 x 22.8 cm, the pigeons only had access to an area of 23.6 x 20 cm (see method section) which was not exactly centred. Therefore, the location of the "screen centre" in experiment 1b was defined as the centre of the accessible part of the screen relative to the left/bottom edge of the screen which was defined as 0/0. Additionally, individual peck distances in cm relative to specific features of the given stimulus such as the largest dot cluster in experiment 2, the most central dot to the rotational centre in experiment 4 or the additional stationary dot in experiment 5 are listed. Furthermore, the coordinates in cm of individual pecks, the coordinates in cm of the centre of rotation and of the centre of mass, and the coordinates in cm of other analysed pattern characteristics relative to the left/bottom edge of the screen (0/0) are given. For experiment 2 also the peck orientation angles in degrees relative to where the largest dot cluster was located 300 ms before the peck had occurred are listed.
