## ReadMe ## This repository provides the data and analysis code from Addleman, Legge, and Jiang (2021, *Cortex*). The text of the paper is available at the linked PsyArXiv page. For questions about the materials here, please don't hesitate to email Doug Addleman at daddleman@dartmouth.edu. ### Overview ### Project materials are available in the `experiments` folder. Within that folder, `code` contains materials for running the experiments 1 and 2, `E1` and `E2` contain data, processing, and and analysis files, and `validationExp` contains all materials related to the experiment validating effectiveness of the simulated scotoma. A short video of trials in the scotoma condition, in .mov and .mp4 file types, can be found in `demos`. Finally, variableKey.csv describes all columns in raw behavioral data files. ### Experimental Code ### Code for running the experiment is available in `experiments/code`. Code is written in MATLAB and requires psychtoolbox and an EyeLink eye-tracking set-up. ### Data ### Each experiment has a data directory: `experiments/E1/data` and `experiments/E2/data`. Each participant has an .xls file consisting of their behavioral data, as well as data from the EyeLink eyetracker in `/data/eyeData`. Running the associated R Markdown file (e.g., MD_E1_ETPreprocess.Rmd) will combine behavioral data with processed eye data to create a combined .csv file of behavioral data and relevant eye data for all participants. The combined .csv files generated by the preprocessing R scripts (one per experiment) are what were used in all statistical analyses. Additional eye data is available for each participant: in raw form as .edf files readable by the EyeLink Data Viewer software as well as .xlsx files created manually in EyeLink Data Viewer using the associated .evs pipeline file. While .xlsx files only have limited data from eye tracking relevant to the current analyses, follow-up analyses could be conducted using additional information in the raw .edf files. ### Analysis Code ### Analysis code is available for each experiment in `experiments/E1/analysis` and `experiments/E2/analysis`. All reported analyses of behavioral data and code to generate behavioral data graphs (in some cases manually combined into figures in the manuscript) are available in the R markdown files (e.g., MD_LPL_E1_Analysis_IE.Rmd). Analysis and creation of figures for first fixation data was done in Microsoft Excel and is available in the .xlsx files (e.g., E1_FirstFixationAnalyses.xlsx). Excel files include sheets for raw data as well as first fixations by quadrant for all participants and unaware and aware subgroups.
