behavioural_data

Each participant’s data are saved in a separate file, e.g. ‘psychophysics_participant_[participant_numer].mat’. The file is a Matlab structure array containing five fields: button presses for the pre-experiment are saved in ‘pre_button’, those for the main experiment in ‘main_button’. Both are a matrix in which each column is a separate trial. Each row is a frame in the presentation of a stimulus. At a refresh rate of 120 Hz this means that 120 rows comprise a second of experimentation. For each frame, a value of 1 indicates a right button press, a value of -1 a left button press and a value of 0 that no button was pressed. ‘pre_gamma’ contains the gamma shape and scale parameter resulting from the pre-experiment. Dominance durations for the main experiment’s replay stimulus were sampled from this gamma distribution. ‘main_conditions’ is a vector containing the order in which conditions appeared through the trials. Lastly, ‘main_output’ summarises statistics computed from the experiment, each row is one of the five experimental runs. The columns are trial number, median dominance for the sphere turning left, median dominance for the sphere turning right, median dominance for all percepts, number of percept switches and total mixed percept durations, as well as gamma shape and scale parameters for each trial’s dominance durations.
