Hi there!

I am new to the world of MST, but I have become very interested in using the face and object MST tasks in an upcoming study of mine. I see the standalone versions for the object stimulus sets, but I have not seen any for the face stimulus sets. I have access to MATlab but do not know anything about coding...

In short, I'm really interested in utilizing these tasks but have no idea where to begin (in terms of what to download, what to program, and how to get the task up and running).

I apologize that this question is so basic for this forum, but would appreciate any help!

Cheers,

Gabriella

Hi Gabriella!

I recommend downloading the stand-alone version from our website: https://faculty.sites.uci.edu/starklab/mnemonic-similarity-task-mst/. You can download the instructions for the task and the stand-alone version is very easy to run. We have not included the face stimuli for the stand-alone version because we have focused on vetting and matching the object stimulus sets. If you are interested in using our face stimuli, we can send them to you directly.

Thanks!

Hi there!

I have a few follow-up questions:

1. When I run the MST, will I need to randomize across sets (or can I have all participants see the same set, i.e., all see set C)?

2. Dr. Kirwain has kindly sent me the face stimuli. How do I integrate the stimuli into the stand alone version?

Thanks again!

1) We typically run two sets at a time, randomizing across participants, but sets 1-6 have already been matched for difficulty, so you can run any set you'd like. If you are doing a pre-/post- design, you would obviously want to counterbalance sets across those timepoints.

2) The faces stimuli aren't set up for the stand-alone version of the task. I believe that you could rename them as pairs (001a, 001b) and link to the folder through the stand-alone version or you could create your own version with Matlab or PsychoPy.
