Anyone build Inhibitory Control Test (a simple Go/NoGo task)?

If this template helps then use it. If not then just delete and start from scratch.

Hello all,

I’m new here so I apologize if this is the wrong sub-forum. I’m trying to use a simple go/nogo task called the “Inhibitory Control Test,” see: It’s used for cognitive testing in patients with advanced liver disease.

I’m wondering if anyone else might have already built it. Here’s the basic description from the paper:
“Inhibitory Control Test
The ICT is a computerized test of attention and response
inhibition that has been used to characterize attention deficit
disorder, schizophrenia, and traumatic brain injury.
ICT is similar to the continuous performance test and consists
of presentation of several letters at 500-ms intervals.
Interspersed within these letters are the letters X and Y.
The subject is instructed to respond to every X and Y during
the initial part of the training run, which establishes
the pre potent response. In the latter part of the training
run, the subject is instructed only to respond when X
and Y are alternating (called targets) and to refrain from responding
when X and Y are not alternating (called lures).
After the training run, 6 test runs, which last approximately
2 min each, are administered with a total of 40
lures, 212 targets, and 1728 random letters in between.
At the end of the test, the lure and target response rates,
lures, and target reaction times are automatically calculated.
Lower lure response, higher target response, and
shorter lure and target reaction times indicate good psychometric
performance. The results were expressed as
number and percent of incorrect lure responses, correct
lure inhibitions, correct target responses, and incorrect target
