Create a stroop effect demo using Psychtoolbox

a) Record the subjects response, the response time (RT), and whether or not their answer was correct. You can choose to store responses either as characters (the button they pressed), or convert to a number (e.g. 0 = congruent, 1 = incongruent) or however you like. RT we will talk about on Wednesday so you can skip for now if you are starting your homework early (as you should be!).

b) Put a line of code at the end of the script that saves the experimental data. You should at least save the conditions (the order and labels of conditions across trials), whether they made a correct response or not, what response they made, and the response time. Use the save function and store the data as a .mat file. You can choose whether you save each of those variables or create a structure that stores them or some other data type.
