Randomly changing the spatial position and visual items

mr_crowley

Hello,
I am working on a spatial perception project. Part of the task includes display of letters in 'A B C D' format while performing a concurrent timing task. Later I want to test the accuracy of the memory for the displayed items in this format ' * B * * '. What would be the most efficent strategy in the testing session for randomly changing the place of the to be displayed letter and creating the right and wrong options ? (eg. ' * B * * '-> True; ' * G * * ' -> False)

Note: I use variables Letter_1-2-3-4 for the display part.

Thanks in advance,

Hi Cagdas,

You could create a list variable that contains 4 sets of coordinates (corresponding to the 4 letter positions). Let's call that variable coordinates. Using position = random.choice(coordinates) you'll have the random position at which to display your desired letter.

Cheers,

Josh
