I’ve read through a bunch of the other threads and it doesn’t seem that anybody has my particular problem(s).
First, I have an experiment where I want subjects to write in the names of colors they have been shown on the keyboard after they appear. In each trial, there is a fixation point for a second, the color appears, there is an ISI, and then a string edit box is supposed to appear. The participant is supposed to fill out the box, click "Enter", and then move on to the next trial. I can't get this to work. If I make the event end "after any response from the participant", then one of two things can happen. If I have the string edit field appear for all events, it freezes when I try to type anything in. If I have the field appear only when an event has a designated correct response, then either (a) the field never appears at all, or (b) it freezes when it does appear and I try to type anything in it. (Whether (a) or (b) happens depends on whether any correct response has been defined, but see below.) Now, I really don't want to define the "correct" answers, because I want participants to type anything in (up to a certain length). But, even if I do designate the "correct" answers, and tell the event to end only after a correct answer, the field still freezes. Really, all I want is a string edit field that disappears after you type something in and press enter. My second problem is about randomization. Each stimulus is a color patch that appears for a certain period of time. The stimuli are defined by the hue of the patch, the size of the patch, and the duration that it remains on screen. I have made a separate event for each hue-size pair. Is there any way that I could have each hue-size-duration triple appear exactly one time each, in random order, without making an individual trial for each triple? I could actually do that, but it would take me a few hours, since there are so many hue-size-duration triples. I haven't been able to get the variable ISI duration thing to work, and I suspect that might be the key. Any suggestions?
Thanks in advance!
