The first experiment is the mispronunciation task from Swingley & Aslin (2000). The final data set following preprocessing is called Mispro_finaldata.txt and the R script used to analyse this dataset is called analyisis mispronunciation. R. The second epxeriment is the Cross-situational learning task from Smith & Yu (2008). The final data set following preprocessing is called CrossB_finaldata.txt and the R script used to analyse this dataset is called analysis cross-situational learning.R. The third experiment is the mutual exclusivity task from Markmann & Wachtel. The final data are in Fertige Daten Mex.xlsx and the script for this dataset is called analyis mutual exclusivity.R. design planning with graphs paired tests.R provides code for the design analysis reported in the appendix.
