Hello everyone,

I'm using SuperLab for the first time and need to design a RSVP task (attentional blink paradigm) for my undergrad dissertation.

This is how it goes:

Each trial has 15 images - 13 distractor images and 2 target images which are faces.
The target images will be presented at specific time lags, and the faces have 3 different emotions: happy, sad or neutral
for example, a trial where T1 is a happy face and T2 is a sad face:
D=distractor, T1=target 1, t2=target 2

DDD T1 D T2 DDDDDDDDD
DDD T1 DD T2 DDDDDDDD
DDD T1 DDD T2 DDDDDDD
DDD T1 DDDDD T2 DDDDD
DDD T1 DDDDDD T2 DDDD
DDD T1 DDDDDDD T2 DDD

I have created a stimulus list for each of the above event lines. I will further create the similar pattern above for the following T1 - T2 combinations:

Happy- Sad
Sad - Happy
Happy- Neutral
Neutral- Happy
Sad- Neutral
Neutral Sad

HOwever this is where I am stuck:

After each event line, participant will need to respond which emotion they perceived for T1 and T2. I have created another trial and stimulus list for the response. But how can i be sure, when I randomize the trials, that the response event will be linked to the right event line above (as i need to take in to consideration time lag and the target emotionality)

If I add the response to each stimulus list, it does not appear only at the end,only but requires a response after each stimulus list item.

I am lost and really need help PLEASE. I am waiting for my ethics packet to be approved and should start running by next week.

I have attached my draft experiment: it is still not complete and still have to figure out a few other things like the cue.. but the response issue i my major worry right now
