Dear Friends:
we have a Stroop study. It is a block design and has three condition blocks,
i.e. Rest, congruent, incongruent. In congruent condition, the red, blue,
green, yellow letter displayed in red, blue, green, yellow ink color,
respectively. In incongruent condition, the red, blue, green, yellow letters
displayed in ink color different the words' meaning. The duration of each
block is 24 seconds.
My question is for this Stroop study, is it better to put a rest block
between each task blocks, or I can put two task blocks in sequence and two
rest blocks together because I want to randomize the blocks?
Thanks
Jiansong
