@Fernando Marmolejo-Ramos asked a question regarding the software that will be used. At this moment, I have not decided, but the program realization will be centralized (probably done by myself and tested by a few persons). At this time, I hesitate between E-Prime (I can buy two “100 E-Run licenses”, they are not too expensive); alternatively, my second choice would be PsychoPy (even though I do not know how to use it yet; if such is the case, I would appreciate some help). Timing accuracy must be high, which excludes java scripts and other packages that are run online or inside a browser.
