Data from Duffy et al. (2025), "The Sound of Success in the Early Palaeolithic: Better Knapping is Brighter, Clearer and More Attention Grabbing"

The CSV file "<b>Acoustic_analysis_data.csv</b>" contains data collected for experiment 1 (an acoustic analysis of strikes by material quality and strike outcome, n=1472). This file contains the following 7 columns:'file': file name for each strike recording'Material': material type (flint, granite or gabbro)'Outcome': strike outcome (success or fail)'dom_mean': mean dominant frequency (Hz)'specCentroid_mean': mean spectral centroid (Hz)'entropy_mean': mean Wiener entropy (0-1)'loudness_mean': mean amplitude (dB)The CSV file "<b>Preference_test_data.csv</b>" contains data collected for experiment 2 (ratings of aesthetic appeal and perceived salience for strikes varying by material quality and outcome, n=10370). This file contains the following 5 columns:'Participant.Public.ID': unique identifier for each anonymous participant'Response': Likert scale response (5=strongly agree, 4=agree, 3=neither agree nor disagree, 2=disagree, 1=strongly disagree)'Question': indicates whether participants' Likert scale ratings correspond to the aesthetic appeal ('Like') or perceived salience ('Attention') question'Material': material type (Flint, Granite or Gabbro)'Success': strike outcome (Yes = success, No = fail)
