Hi,


I'm having a problem with the data output for a delayed response memory task. During the task, participants are presented with a list of positive and negative words in white. Then one word (positive or negative) is presented in yellow. The yellow may or may not have been in the previous list of white words. Participants are to select "yes" if the yellow was in the previous list and "no" if it wasn't. The task is working well except that some of the trial codes are being mislabeled. You can see in the data file (attached) that every few trials the program will call a trial an "in" trial, meaning the probe word (yellow word) was in the previous list (of white words), when in fact it was not. Because of that error, correct answers are being coded as incorrect. This only happens occasionally and sometimes the "in" trials really are correct (i.e., the yellow word was in the list of white words). Below I have pasted the code and the data file is attached. Any help would be greatly appreciated!

Hi there,


I'm looking into this, but I can't get your script to compile. Specifically, the script makes reference to an <item in> element in a number of places, but no such element is defined in the script. Is it possible you missed something when copying and pasting?


Perhaps you could just attach the entire script to the thread.

Thanks for looking into this! Please see attached- perhaps I did miss something with copy/paste.

Hi,


Sorry to bother you, but I was wondering if you might be able to estimate when I would hear back about my post. I'm new to the forum and am just not sure how long this typically takes. Did I attach all of the necessary files?  Thanks so much for your help!

Hi Whitney,


Sorry for the delay, and thanks for the reminder about this.


For each memory test, the script presents each word and adds it to the "in" stimulus set. An "in" trial will then randomly present an item from the "in" stimulius. After that, the in stimulus set needs to be cleared out for the next test. It doesn't appear your script is clearing it out, so you end up with items from previous tests being counted as "in".


If you add the following command to the <trial reset> element, it will clear the items from the "in" set before running the next trial:
/ ontrialbegin = [clear(text.in)]


You also may want to double check that your out trials are correct. The original Sternberg script that this was adapted from is used a single stimulus set called "out" for both the presentation and recognition phases. Since it selected without replacement, the item selected for the recognition phase (i.e. the target) would not be the same as any of the items in the presentation phase.


Hope this helps,
Sean
