# **Bias and modality in conditionals: experimental evidence and theoretical implications** *Mingya Liu (Humboldt University of Berlin), Stephanie Rotter (Humboldt University of Berlin), Anastasia Giannakidou (University of Chicago)* This repository contains the experimental stimuli, data, plots, and code for two rating experiments (exp1 and exp2) in German. A detailed description of the studies can be found in the paper. ## Code This folder contains the .R files for exp1 and exp2 which were used to preprocess the data, provide descriptive statistics, plots, and the analysis. The latter was was performed using cumulative link mixed models for ordinal regression implemented in the ordinal package for R. The scripts use the raw data files from the folder 'Data'. ## Data This folder contains two .txt files with the collected data for exp1 and exp2 respectively. - The raw data : untouched files after the data collection - The preprocessed data: the rating data have been cleaned of - (i) participants who did not correspont to the requirements (i.e., German native speaker), and - (ii) participants with a lower accuracy rate in the control question of 85%. The preprocessed file can be generated by using the first 230 lines of the code by using the raw data. ## Plots This folder contains .png files of the plots of the ratings for exp1 and exp2. There is one coloured and one black/white friendly version for each experiment. The code for the plot generation can be found in the R-code files. ## Stimuli This folder contains the .csv files with the stimuli used in exp1 and exp2. The design and method was similar for both studies.
