Hi,
I'm new to inquisit and trying to modify the regular Ospan-task from the millisecond library for my master's thesis.
https://www.millisecond.com/download/library/ospan/ -> this is the regular task.
After answering whether the answer for a math problem is correct or incorrect, a letter appears on screen for the participant to memorize. For my task, I want to show the participant a picture of a light bulb above it. This light bulb will be either turned on in 20% of the trials or turned off in 80% of trials.
These are the stimuli that I made:
<picture lightbulb_off>
/ items = ("lamp_uit.png")
/ position = (50, 30)
/ size = (20%, 20%)
</picture>
<picture lightbulb_on>
/ items = ("lamp_aan.png")
/ position = (50, 30)
/ size = (20%, 20%)
</picture>
and this is the script that the regular task uses for the presentation of a letter:
<trial show_letter>
/ ontrialbegin = [values.lettercount+=1]
/ ontrialend= [item.PresentedLetters.item=text.Letters.currentitem]
/ pretrialpause = 200
/ stimulusframes = [1=BlackFrame, GrayFrame, Letters, currentsetsize]
/ trialduration = values.learninginterval
/ validresponse = (noresponse)
/ branch = [if(values.lettercount==values.currentsetsize)trial.recall_letter]
/ branch = [if(script.currentblock=="PracLetter")trial.show_letter else trial.InitMathProblem01]
/ recorddata = true
</trial>
Is there anyone who would want to offer me some help with this?
Thanks in advance.
