README for human auditory behavioral data (last updated on April 9, 2020) The accompanying file `human_auditory.csv` contains all behavioral data from the human auditory task, first presented in Akrami et al. 2018 [1]. The data set contains behavior for 11 human subjects across a combined 9507 trials. Data was collected from each subject within a single session. Relevant portions from the Methods section of the paper ("Human subjects (auditory)" and "Human auditory behavior") are reproduced below: "11 human subjects (8 males and 3 females, aged 22–40) were tested and all gave their informed consent. Participants were paid to be part of the study and were naive to the main conclusions of the study. The consent procedure and the rest of the protocol were approved by the Princeton University Institutional Review Board." "In this experiment, subjects received, in each trial, a pair of sounds played from ear-surrounding noise-cancelling headphones (brand 233621-H501). The subject self-initiated each trial by pressing the space bar on the keyboard. The first sound was then presented together with a green square on the left side of a computer monitor in front of the subject. This was followed by a delay period, indicated by ‘WAIT!’ on the screen, then the second sound was presented together with a red square on the right side of the screen. At the end of the second stimulus and after the go cue, subjects were required to compare the two sounds and decide which one was louder, then indicate their choice by pressing the ‘k’ key with their right hand (second was louder) or the ‘s’ key with their left hand (first was louder). Written feedback about the correctness of their response was provided on the screen, for individual trials as well as the average performance updated every ten trials." Data description, by column: 1) subject_id: The ID of the human subject (11 total subjects, #1-11) 2) trial: The trial number 3) stim_pair: The ID of the stimulus pair used in the trial. There are 10 different pairs used. Pairs 1-5 have stimulus A > B, and so are rewarded on the right side; pairs 6-10 have stimulus A < B, and so are rewarded on the left side. The values of stimuli A and B corresponding to each pair can be inferred from the "s_a" and "s_b" columns, and are also written explicitly below (see Extended Data Figures 1E and 3B [1]) 4) s_a: The loudness of stimulus A (pink noise), in decibels (dB) 5) s_b: The loudness of stimulus B (pink noise), in decibels (dB) 6) choice: The choice made by the subject, where Left=0 and Right=1 7) correct_side: The rewarded (correct) side, where Left=0 and Right=1 8) reward: If the subject was rewarded (made the correct choice), where No Reward=0 and Reward=1 9) delay: The delay, in seconds, between the presentation of stimuli A and B (either 2, 4, 6, or 8 seconds) Stimulus Pairs: 1: (62.7, 60); 2: (65.4, 62.7); 3: (68.1, 65.4); 4: (70.8, 68.1); 5: (73.5, 70.8); 6: (60, 62.7); 7: (62.7, 65.4); 8: (65.4, 68.1); 9: (68.1, 70.8); 10: (70.8, 73.5) [1] Akrami, A., Kopec, C.D., Diamond, M.E. and Brody, C.D., 2018.
