[open] help with sketchpad
Hello, i'm building a quite simple experiment with one categorial variable. This variable represent a simple arrow directing either to the right or to the left (two levels). I tried to draw this two arrows and defined them in the "experimental loop" by the name "arrows" with two levels of right and left. Furthermore i defined anothr variable of correct response: L for the right arrow and S for the left arrow. Also i pointed for 2 cycles (for this two levels of arrow variable) with 50 repeated trails (a whole of 100 trails for a sequence). The only thing is that i couldnt find the way to for applying a random representation of those two types of arrows in the trial sequence. I would appriciate any help about this.
