Adaptive computerized test for memory, thinking, and attention
Adaptive Testing of Cognitive Function based on multi-dimensional Item Response Theory
This project builds a short, computer-based test for adults that measures memory, language, attention, processing speed, and reasoning to help spot early changes in thinking.

What this research studies
You would take a brief, adaptive computer test that changes which questions you get based on your earlier answers so the test is fast and tailored to you. The test will measure overall thinking ability plus five specific areas: episodic memory, language/semantic memory, processing speed, attention/working memory, and flexible thinking/reasoning. Researchers will create a large bank of questions and use modern statistical models to choose the most informative items so people can be retested over time without repeating the same questions. The test is being designed to work in clinic settings or remotely so it could fit into regular care or home monitoring.
Who could benefit from this research
Good fit: Adults aged 21 and older who are concerned about memory or thinking changes, at risk for Alzheimer’s disease, or willing to participate in cognitive testing are ideal candidates.
Not a fit: People who cannot use a computer or who need a full traditional neuropsychological evaluation (for example due to complex medical issues or severe sensory/motor impairments) may not benefit from this brief computerized test.
Why it matters
Potential benefit: If successful, this could make it easier to detect subtle cognitive decline earlier and monitor changes over time with a quick, repeatable test.
How similar studies have performed: Computerized adaptive testing has worked well for other health measures and some cognitive tools exist, but applying multidimensional item response methods to create a repeatable, comprehensive cognitive CAT for Alzheimer detection is relatively new.
