Psychophysics

• Raw data are stored per task (Detection_raw_data and Discrimination_raw_Data)

Analysis steps:

1. Run first SoEThresh_Detection.m, SoEThresh_Detection_DPrimeAnalysis.m, and SoEThresh_Discrimination.m

   • The output data of these scripts will be used for the psychometric fitting procedure and statistical analysis in R

2. Run 1.Detection_Task.R and 2.Discrimination_task.R

3. Keep in your global environment in R the data created in Step 2 and run 3.Correlations.R.
