visual attention task with a grid of squares
I am looking for advice! Premise: I have no experience with Python (I used OpenSesame in the past, but with simpler experiments)
I want to program an experiment in which the participant sees a grid of squares (say 30 x 30) on a tablet pc. The participant puts the finger in a central position (eg fixation dot) and as soon as s/he reaches this position, one of the square of the grid change the color. The participant has to touch the specific square and go back to the central position. Then the next trial begins.
I need to present the colored squares in random position but half on the left and half on the right of the screen/grid)…and of course I need to register if the participant press on the right square.
Any help or suggestion would be appreciated!
