In my experiment, I have 2 separate blocks which require unique background stimuli. However, the background stimuli from the first block is carrying over to the second block. I know that there is a clear screen function, but I do not know how to use it/ where to put it. This is what I have
<Block Practice_num>
/bgstim = (button.1n, button.2n, button.3n, button.4n, button.6n, button.7n, button.8n, button.9n)
/trials = [1= sequence(1_R, 2_R, 3_R, 4_R, 6_R, 7_R, 8_R, 9_R, 1_L, 2_L, 3_L, 4_L, 6_L, 7_L, 8_L, 9_L) ]
/showmousecursor = true
/ onblockend = [("clearscreen")]
</Block>
Thank you in advance
