Results files
The main results file is a comma-separated values (CSV) file. Note that the CSV separator is not necessarily a comma, and can be changed in the General
Preferences tab accessible by clicking Edit
, and then Preferences
. The main results file contains a row for each trial with the following fields:
listener: the listener identifier
condition: the experimental condition
block: the block number
trial: the trial number
azimuth_angle: the stimulus azimuth angle, as specified in the parameters file
elevation_angle: the stimulus elevation angle, as specified in the parameters file
response_azimuth: the response azimuth angle
response_elevation: the response elevation angle
azimuth_error: the signed azimuth angle error
elevation_error: the signed elevation angle error
azimuth_angle_remapped: the stimulus azimuth angle remapped to the 0-360° range
response_azimuth_remapped: the response azimuth angle remapped to the 0-360° range
azimuth_angle_flip: the stimulus azimuth angle obtained after flipping (reflecting/mirroring) the stimulus positions from the rear to the front
response_azimuth_flip: the response azimuth angle obtained after flipping (reflecting/mirroring) the stimulus positions from the rear to the front
azimuth_error_flip: the azimuth error calculated from stimulus and response angles flipped to the front (this is one way to calculate errors while ignoring front-back confusions)
front-back: [
0
,1
] 1 if the listener made a front-back confusion, 0 otherwisesound_file: the sound file used for the trial
base_level the base level, in dB SPL, for the trial
rove: the level rove range for the trial
actual_level: the actual level at which the stimulus was played
date: the date
time: the time
sound_source_id
additionally outputs summary files for the all the trials, as well as by experimental condition and/or by block if multiple conditions/blocks are present (and by block x condition). For each of these subdivisions of the results, one summary file gives root-mean-square (RMS) azimuth and elevation errors, and the other front-back error proportions. The RMS error files contain the following fields:
listener: the listener’s identifier
rms_azimuth_err: the RMS azimuth error
rms_elevation_err: the RMS elevation error
rms_azimuth_err_flip: the RMS azimuth error calculated after both stimuli and responses positions have been flipped from the rear to the front (this is one way to compute RMS errors while ignoring front-back errors)
azr_rms_err_no_FB: the RMS azimuth error calculated after excluding trials with front-back errors (this is another way to compute RMS errors while ignoring front-back errors). Front-back errors are defined here as cases in which the RMS error is reduced after flipping both stimuli and responses positions to the front
The front-back error files contain the following fields:
listener: the listener’s identifier
front_back: the proportion of front-back errors
