- *alternative_regression_discussion.doc* contains the results section for analyses in which all 11 acoustic variables simultaneously predicted each of the 4 social functions, resulting in 4 LMEM models.
NOTE: to run R script, have all data files in the working directory.
- *laughter_analyses.R* contains all the R code to run the analyses and generate the descriptives and figures from the paper.
- *cleanedSubjectData_May152017.csv* Qualtrics participant data, with cleaned up formatting
- *laughs_420_data.csv* acoustic data generated by Praat for laugh samples. Subsequently, 20 of these laugh samples were excluded for
not meeting our inclusion criteria.
- *soundSnap2nddownloadcode.csv* filenames, etc. of sound snap laugh samples. Necessary for data cleaning and merging stage.
- *URLs_for_qualtrics.xlsx* contains the URLs for the laugh samples in Qualtrics. Necessary for data cleaning and merging stage.
- *regression_coefficients_adjustedPvalues_forplot.csv* the file used to generate the coefficient plot
- *regression_coefficients_adjustedPvalues.csv* the file outputted after all models are run, with Benjamini-Hochberg adjusted p values
- *regression_coefficients_sep.csv* regression coefficients with unadjusted p values
- *cross_tabs_effects.xlsx* is a figure in the paper
- *acoustic_descriptives.csv* contains summary descriptives
- *regression_table.csv* unformatted regression coefficients table (Table IV in paper)
