While at the University of Iowa, I administered the MTT for a research protocol under Drs. Sara Cavaco and Steven Anderson. At that time, we used pen and paper traces, scoring everything by hand. This was years ago, however, so it is possible that Dr. Cavaco has since developed a computerized scoring system. The most recent email address I have is [email protected]. Best of luck.

Thanks Sara. I will inquire about it.

If all of the scans are of the same size then another method would be to create a macro that deletes the region in which the trace was supposed to occur as well as any other non-trace related parts of the image, and then simply finds the sum of the total number of pixels that occurred outside the boundaries. This assumes every subject used the same pen type (same line thickness).

Thanks for the feedback Denton. In what application would you suggest building such a macro? Photoshop?

Photoshop should have sufficient scripting capabilities to pull something like this off. I haven't personally done anything exactly like this but have used it in the past for automation of manual tasks.
