[solved] sketchpad does not end after response
Hi guys, I set up an experiment that contains presenting first a series of 12 study sentences and then a series of 24 test sentences that participants have to evaluate as true or false. I use sketchpad items to present both the study stentences (for which I set the actual text in an inline) and the subsequent 24 test sentences (for which I set the text in a loop). While the study sentences work fine (i.e., pressing the spacebar proceeds immeidate to the next sentence), the test sentences do not. When I respond (by pressing F or J) the sketchpad does not end as it should but I have to instead press F or J multiple times before it proceeds to the next sentence. Don't know what's causing this...is it the keyboard_response item, the logger or...? Any ideas what's going on?
Thanks in advance,
marios

Hi Marios,
Usually, when this happens, the
keyboard_responseis preceded by asketchpadwith a 'keypress' duration. So you have to press one key during thesketchpad, and then another key during thekeyboard_response. Could it be that?And, btw, nice to have met you in Oxford!
Cheers,

Yep! that was it. I changed the "keypress" to 0 in the duration field of the sketchpad and everything works fine. I also have a sketchpad to provide instructions at the very beginning of the experiment which is a bit slow to react to the keypress. This sketchpad is not followed by a keyboard_response item but instead by a loop. Any idea what is causing the delay there? It's not important for the experiment....I'm just curious! Anw, thanks very much for your help Sebastiaan. It was indeed very nice to meet you and hear about your research (awesome stuff by the way!).

That would be the preparation time of the
loop, or rather (probably) thesequencewithin the loop. What you could do is add a blanksketchpadwith a 0 ms duration just before theloop. That way the display will be blanked immediately after the key press. It doesn't actually reduce the preparation time, but it might make things feel smoother.Check out SigmundAI.eu for our OpenSesame AI assistant!
Thanks Sebastiaan. I had a feeling it was the preparation of the loop/sequence causing the delay but I had to know for sure
