Millisecond Forums

Dear all,

for an experiment I would like to design a program that consisits of two blocks.
The first block consists of video presentation followed by a question the participant is asked to answer.
Within a second block - the participant is again presented videos - but this time - the participant shall be allowed to watch the video as often es he/she wants. After the participant decides that he has watched the video often enough he shall be forwarded to the same question as in block one.
I interpreted "repetetion" as wrong answer, and "non repetetion" as correct answer. The aim was to program the trial in a way that as soon as the participant gives the "correct" answer - the repetition of the video scene stops and the question appears. However, I am not sure about the "name tag" of my branch. I tried it with "correctstreak" but that does not work. 
Does anybody know the solution to this problem? thank you very very much in advance!


experimental trial without repetition

<trial playvideo_kein_Tor>
/ stimulustimes = [0=fixation; 1000 = Videos_kein_Tor]
/ timeout = 10
/ validresponse = (noresponse)
/ branch = [trial.showquestionaboutmyvideo]
</trial>

<trial playvideo_Tor>
/ stimulustimes = [0=fixation; 1000 = Videos_Tor]
/ timeout = 10
/ validresponse = (noresponse)
/ branch = [trial.showquestionaboutmyvideo]
</trial>

<trial showquestionaboutmyvideo>
/ stimulustimes = [0=Entscheidung_Manipulation; 0=Zeichen_Tor; 0=Zeichen_Tor_II; 0=Zeichen_kein_Tor; 0=Zeichen_kein_Tor_II]
/ validresponse = ("a", "l")
/ correctresponse = ("a", "l")
</trial>

<block experimentblock_ohne_wiederholung>
/ trials = [1 - 44=noreplace(playvideo_kein_Tor, playvideo_Tor)]
</block>
