Hello Michael and everyone,
There has been a change in my task design. Please I need an assistance once again.
I have 80 sets of images to present to the participants in a 2 n back task. I will have 2 blocks. So in first part, I will present 80 pictures, followed by a break then I present another set of 80 pictures to the participants.
Their task is to compare whether the current picture matches with the picture presented 2 back in terms of emotional valance. That is, if the two pictures match as positive emotional expression or negative emotional expression.
The right key should be pressed when there is a match, and the left key pressed when there is no match.
The pictures will be presented sequentially. However, I want the order of the blocks to be presented randomly for each subject .
I need to record their accuracy and response time.
