Data and analysis code associated with the paper titled "Strategic stabilization of arousal boosts sustained attention". The data is organized as a dataframe in .csv format, with the following column names: subject_id = subject ID session_id = session ID date = date start_time = start time (hour of day) block_id = block ID (0-6) trial = trial ID reward = task utility (0 = low; 1 = high) noise_dur = noise duration catch = catch trial (0 = trial with signal; 1 = trial without signal) rt = reaction time w.r.t. trial start time (in seconds) outcome = outcome of trial (0 = hit; 1 = miss; 2 = false alarm; 3 = correct reject) time_trial_start = trial start time w.r.t. session start time (in seconds) time_trial_end = trial end time w.r.t. session start time (in seconds) trial_since_hit = trial number since first hit in a block pupil_trial_start = pre-trial pupil size (% of max) walk = pre-trial walking (0 = still; 1 = walking)
