The columns, from left to right, are as follows: subject (name of the subject), species ("wolf" or "dog"), sex ("m" or "f"), age_days (number of days that passed between the animal's birth and the date of the test), phase ("asso": first phase, associative learning; "acq": acquisition for reversal learning phase; "rev": reversal learning phase) set_no (number of set/reversal presented to the animals within the phase), date (dd/mm/yyyy format), session (number of session within the set/reversal), trial (number of trial within the session), pos_stimulus (identity of the positive stimulus), neg_stimulus (identity of the negative stimulus), pos_color (color of the positive stimulus), neg_color (color of the negative stimulus), correct_side (side of the correct stimulus: "l": left, "r": right), order_positive (1: positive stimulus presented first, 2: positive stimulus presented second, 0 or empty: no information available), outcome_session (1: successful session —9 or 10 correct trials out of 10—, 0: unsuccessful session —less than 9 correct trials), outcome_trial (1:correct, 0:incorrect), experimenter (identity of the experimenters, empty if the data is not available), notes.
