I am currently working on a source memory task where I’m pairing an image with a word during study. During test, participants are shown all image options on the screen and are presented with new and old words and need to click a key corresponding to what image the word was paired to (or new).
The task runs fine and there are no issues with that, however, there are a couple of things left I need to do for some data to be added to the data file.
- The study image is recorded into the data file but in the long path to the actual image file.
-Here I want to add something into the routine that will also include a single letter to correspond to
the source (e.g. ‘x’) individuals in the images.
2. The test data is added to the output file (the word and then the key
-Here I want to have something that will auto-grade the response. So, if the participant’s source response was correct, a misattribution, false alarm, or correct rejection.
I didn’t know what would be helpful to include, but I attached the overall task code, study code, and test code. Also, the stimuli file I fed in has two columns, a word list, and an image list.
Thanks in advance and let me know if there is more information you need!
I’m a bit confused about what you’re trying to do, but I’ll try my best to help from what I understand:
- So you’re saying that the output for the images has the entire folder/file name, but you want just the file name, correct? If so, you can treat the output name as a string and call to the last few letters in the string. For example, if your file name is
html/resources/image1.png and you want the output entry to say
image1.png, you can write:
oldFileName = html/resources/image1.png #but call to the variable that you were originally saving
fileNameStart = 15 #the position of the 'i' in the oldFileName that I got from just counting (this is assuming all of the images are in the same folder)
imageName = oldFileName[fileNameStart:]
#imageName = "image1.png"
- If you’re just trying to make a correct/incorrect column in the output file, you can simply make a
correctResponse variable that corresponds to the correct key response for that trial, check the ‘store correct’ box in the keyboard component, and enter
$correctResponse in the box as the correct answer. Psychopy will then automatically make you a correct/incorrect column called
Anyway, I hope I understood your questions correctly and that I was able to help!
