Recording correct answers in a randomized multi-stimuli trial (case 28713)
Hello!
I am creating an experiment to test a child’s learning of a novel knowledge base for my dissertation using DirectRT’s touch screen capabilities. I’ve been trying to run a trial where the subject will select—by using a touch screen—from a picture array of 4 options (which are randomly placed in the four quadrants). In the Log file, the response choice is recorded (which of the 4 quadrants were touched) and the system tries to record if it is correct. However, this is not a correct recording as it is recording “True” if a subject response is in the 1[SUP]st[/SUP] quadrant (because my Time column in my input file lists rt:1,2,3,4 so 1 is considered the correct response for all, regardless of random presentation of stimuli).[ATTACH]2284[/ATTACH][ATTACH]2284[/ATTACH]
Primarily, I am concerned with recording the correct response. However, I may want to also do an item-analysis and would want to know the stimuli they chose if it was incorrect. I have tried to label my stimuli so that I could tell which stimuli was chosen but the log file is not reporting which image was chosen, only which image was chosen randomly to be in the 4[SUP]th[/SUP] quadrant (“Stim” column).
I am attaching a zip file of my task including all necessary files (input, style, touch text file, stim folder, and data folder).
Thanks so much for any suggestions!!
