Dear Inquisit,
I've run some successful scripts via Inquisit recently, mostly thanks to the extraordinary help offered by those on this forum.
I'm running a new, but similar, time estimation study that involves a rotating dot around a clock, and on pressing the correct button, produces the appropriate sound. The participant's task to judge the time interval between their button press and the sound appearing.
The clock-face(s) is essentially a set of images with a dot at a given position to indicate the time. Currently I'm using the /timeout expression = 60 to give the impression of a rotating dot at the desired rate (hence the requirement for the 'pretrial' so that the fixation cross only appears at the beginning - if there's an elegant way to not have a pretrial, that would be fantastic). However, this introduces a blinking effect - i.e., the continuous presentation of the appropriate .jpeg images (through continuous presentation of the trial) gives a strobe effect, instead of the continuous display of the images and the dot rotating around the clock. Is it possible to fix this? This also introduces the issue that, if the participant presses the button between the trials (i.e., the 'blink'), it naturally does not register a response.
Two other small queries are that I would like .jpegs to still continuously appear for a time (so that the dot rotates a random amount of time between 1000ms - 2500ms) after the participant presses the button. I've tried introducing a new trial, but this doesn't seem to work (and undesirably still requires a correctresponse, seeing as I am using the /timeout expression to rotate the dot around the clock). The other is that I would ideally like the /correctmessage sound to be delayed by 250ms. I've tried editing the physical sound, but either Inquisit plays the sound despite the 250ms gap, or doesn't play the sound at all.
I'm aware these issues are largely caused by the use of the /timeout expression, so I apologise in advance for the trouble. I have attached my script and some of the clock-faces to help my issue seem clearer - I also apologise for my confusing description.
Many thanks,
Josh
