This is the data repository for Moore, Pai & Palmer (in preparation). It provides all of the raw data from the four experiments in that paper. The project is organized into three components: raw data, data summaries, and example analysis code. The data files are text files with the suffix ".dat". The names of the data files have three parts. The first part is a code for each experiment. The four experiments use the codes: lo1, lo31, lo30, and lo14. The second part is the initials of the subject. And, the third part is the session number. For example, for experiment lo1, subject aa and session 10, the file name is lo1aa10.dat. The data summaries are mean values of performance (percent correct for Experiment 1 and area under the ROC for the others) for the main conditions broken down by each subject. The summaries are spreadsheets in both Excel format and pdf. The example analysis code is in matlab. It provides an example analysis of one subject of the main effects of simultaneous, sequentail and repeated dual-task conditions. That component also describes the data format of the files in detail. readme file for project wiki John Palmer last revised 4/19/2021
