Voicerecord issue

Group: Forum Members Posts: 5, Visits: 4	Hello all, I was wondering if someone could help me with the script for an experiment I am currently working on. I've been messing around with it for a while now, but I just can't seem to get it to work properly. The idea is to present a picture for 10 seconds and record all responses participants have (to be spoken into the microphone) during this time period (i.e., a think-aloud task). The problem is that I cant get my script to keep recording for the whole 10 seconds, (In other words: how do I get it to just record all spoken answers without stopping the presentation of the picture/and or stop the recording?). This is the basis so far: <expt 1> /blocks = [1=test_control] </expt> <page pre> ^^start </page> <page post> ^^exit </page> <block test_control> / trials = [1= test_control] /preinstructions = (pre) / postinstructions = (post) </block> <trial test_control> / stimulustimes = [0 = control] / timeout = 10000 / inputdevice = voicerecord <expt 1> /blocks = [1=test_control] </expt> <page pre> ^^start </page> <page post> ^^exit </page> <block test_control> / trials = [1= test_control] /preinstructions = (pre) / postinstructions = (post) </block> <trial test_control> / stimulustimes = [0 = control] / timeout = 10000 / inputdevice = voicerecord </trial> <picture control> / items = ("control.jpg") / position = (50, 50) </picture> </trial> <picture control> / items = ("control.jpg") / position = (50, 50) </picture> I've tried several things so far, but I just cant make sense of what to add to it to solve my problem. I hope there is someone here who could help me:) Kind regards, Jeroen Tags think-aloud Voicerecord

Group: Forum Members Posts: 5, Visits: 4	For clarity, here it is once: <expt 1> /blocks = [1=test_control] </expt> <page pre> ^^start </page> <page post> ^^exit </page> <block test_control> / trials = [1= test_control] /preinstructions = (pre) /postinstructions = (post) </block> <trial test_control> / stimulustimes = [0 = control] / timeout = 10000 / inputdevice = voicerecord </trial> <picture control> / items = ("control.jpg") / position = (50, 50) </picture>

To enforce a fixed duration, use /trialduration. For details re. the various components involved in trial timings, see the "How to Control Trial Duration and Inter-Trial Intervals" topic in the documentation. #2: Another thing to consider is /responseinterrupt. The default is 'immediate', which probably isn't what you'd want here. To sum up, I would try something along the lines of <trial test_control> / stimulustimes = [0 = control; 10000 = control] / inputdevice = voicerecord / pretrialpause = 500 / posttrialpause = 500 / trialduration = 11000 / responsetime = 0 / responseinterrupt = frames </trial>
