Data relating to the ICA publication "Pupil dilation reveals changes in listening effort due to energetic and informational masking"

This repository contains the results and analysis script for the experiment described in:J Woodcock, BM Fazenda, TJ Cox and WJ Davies (2019). "Pupil dilation reveals changes in listening effort due to energetic and informational masking". In Proceedings of 23rd International Congress on Acoustics, ICA.Running the MATLAB script './analysis/readPupilData.m' will read and process the raw results files contained in './results/*.mat'. This will generate a .csv file with the processed results named 'ProcessedResults.csv'.The R Markdown script './analysis/listening_effort_analysis.Rmd' will run the statistical analysis and generate the plots in the paper.Running the MATLAB script './generate_stimuli/generateMixtures.m' will make the stimuli used in the experiment and store them as .mat files in './generate_stimuli/stimuli'. To run this script, the zip file containing all Harvard sentences produced in quiet condition should be downloaded from here and unzipped into './generate_stimuli/speech_wavs': https://doi.org/10.7488/ds/2482

本仓库包含J·伍德科克（J Woodcock）、BM·法泽达（BM Fazenda）、TJ·考克斯（TJ Cox）与WJ·戴维斯（WJ Davies）于2019年发表于第23届国际声学大会（International Congress on Acoustics, ICA）论文集的论文《瞳孔扩张（pupil dilation）揭示了能量掩蔽（energetic masking）与信息掩蔽（informational masking）引发的聆听努力（listening effort）变化》中所述实验的结果与分析脚本。
运行位于`./analysis/readPupilData.m`的MATLAB脚本，可读取并处理`./results/*.mat`路径下的原始结果文件，最终生成名为`ProcessedResults.csv`的处理后结果CSV文件。
位于`./analysis/listening_effort_analysis.Rmd`的R Markdown脚本可执行统计分析，并生成论文中的图表。
运行`./generate_stimuli/generateMixtures.m`的MATLAB脚本可生成本实验所用的刺激材料，并将其以.mat格式存储至`./generate_stimuli/stimuli`路径下。
运行该脚本前，需将包含所有安静环境下生成的哈佛语句的压缩包从以下链接下载并解压至`./generate_stimuli/speech_wavs`目录：https://doi.org/10.7488/ds/2482
