Use a staircase method in open sesame?

Daniel4Psych

The premise is, you see the face (either happy or sad) then click a key depending on answer (e.g left for happy and right for sad). If you get the answer right the face is on screen for less time and if you’re wrong it’s on for more time. Is this up and down time method possible in OpenSesame?
Basically a speed test for recognising emotions, help would be greatly appreciated

Hi,

Opensesame used to have a Staircase plugin, but I don't think it still is maintained.

Implementing it shouldn't be too difficult though. Maybe this discussion provides you with a nice starting point: http://www.cogsci.nl/forum/index.php?p=/discussion/254/solved-staircase/p1

Also, this version of Opensesame is a a little outdates, but it has the staircase implemented. If you download it, you will find stair_case python scripts in the folder plugins. Based on them you might also be able to fix it.

Good luck,

Eduard
