EXPERIMENTAL INFORMATION
This experimental script, and the associated files were employed in a 
research study in the Effort Lab (www.effortlab.website) facilities at 
Liverpool John Moores University (LJMU) between 2016 and 2018. 
In the study, participants completed a speech-in-noise task under 4 levels 
of listening demand, while their physiological responses were recorded. 
Participants had to listen to short stories presented in various levels of
background noise (depending on the listening demand condition) then answer 
a comprehension question about the story with 3 multiple choice options.
For further details of the experiment, please contact Michael Richter 
(m.richter@ljmu.ac.uk, m.richter2020@outlook.com), or Kate Slade (k.slade2@lancaster.ac.uk) 
or read the methods description in the associated paper.

METADATA
The SladeRichterEtAl_2020.zip file includes the experimental script used 
to present all experimental stimuli and collect participant responses 
in this study, as well as all associated audio files and transcripts of these. 
The SR_20_InquisitScript folder contains to experimental script 
'K2_StudyScript', as well as a subfolder 'FilesRequiredtoRunScript' containing 
all stimuli files needed to run the experimental script in Inquisit software. 
The SR_20_AudioFiles folder contains the audio files, used as the stimuli in 
the study, which were short stories spoken in the presence of background noise. 
The audio files are labelled according to the study condition, and thus level of 
background noise they are presented in. File names starting with the letter L 
indicate the low listening demand condition, M for the moderate condition, H 
for the high, and I for the impossible, or very high listening demand condition. 
Where the letters L, H, M, or I, are followed by a P this indicates that these 
audio files were used in the two practice trials of that condition. 
The SR_20_StoryTranscripts.doc file contains typed transcripts of all the 
audio files, as well as the associated comprehension question, and multiple 
choice answer options presented to the participants. 
The SR_20_ScreenCaptures folder contains screen capture images of each stage of 
the experimental script, as it would be presented to a participant.
