This is code for the replication of Seli et al. (2016), which is part of the Collaborative Replication and Education Projects (CREP). I share this for other to try out and use.

Note that this public experiment only involves 2 blocks of 45 trials for piloting purposes. The code in the routine SetBlockLengths allows you to change this (to 20 if you are replicating Seli et al., 2016).

Also note that I disabled actual submitting of data by Never stopping the routine Debrief. This means you can only exit the experiment by pressing 'Esc' and closing the browser window. My settings on Pavlovia are such that in that case no data is saved. If you use this for your own experimentation, you should in the routine Debrief change the settting of Debrief_mouse: 'End routine on press' to 'valid click'.

Race categorization task in which participants are asked to respond 'black' or 'white' to faces presented for750 ms. The stimuli set comprises 16 face models (8 female; 8 male). Each model is presented in 11 racial morphing levels, totaling 176 trials +20 training trials. Response rate can be adjusted in an appropriate funcion (e.g., logistic) to calculate categorization threshold and slope. Developed by 'Grupo de Pesquisa em Percepção Visual' at University of Brasília, Brazil.

A forward and Backward Digit Span test for Working Memory The test adapts to participnts' answers and a score is calculated following Woods et al. (2012)

A short demonstration (30 trials) of the switching_task which is similar to the Stroop test but with left and right arrows with colors that are sometimes mismatched.
