id_potential_multispeaker_recs.py

• USE: iterates through Annotation file tracker_CAREER.xlsx to identify recordings where tot_num_speakers > 2
• OUTPUT: multispeaker_output.xlsx

search_download_box_files.py

• USE: facilitate downloading of potential multiparty recordings (multispeaker_output.xlsx) from Box
• OUTPUT: downloaded eaf files to downloaded_eafs

confirm_and_visualize_multiparty_in_eaf.py

• USE: iterates through multispeaker_output.xlsx to find recordings with multiparty interactions through the following logic:
  1. identify center of interaction by finding a point in time in the recording where the time between the offset of the previous annotation and the onset of the next annotation in non-CHI tiers is < 30 seconds
  2. from there, extend outwards to find the boundaries of the interaction. as we extend backwards and forwards, we've reached an interactional boundary if there is no annotation from ANY participant (including CHI) within 10 seconds from the current annotation
• OUTPUT: interaction plots for each recording are saved to interaction_plots to visualize participant turns over the course of the recording. multi_party_interactions.csv stores this in csv form

graphs_analyses_multiparty_recs.py

• USE: given multi_party_interactions.csv and utterance_timing.csv produced by confirm_and_visualize_multiparty_in_eaf.py, produce graphs for basic stats and density plots for main analysis
• OUTPUT: main analysis density plots get saved in the density_plots_by_age directory. other basic stat graphs save to root folder

stats.py

• USE: run basic descriptive stats for multiparty interaction bouts (overall and by age group) + chi-square goodness-of-fit tests
• OUTPUT: saves to descriptive_stats.csv and statistical_tests_results.csv
