Visuospatial Ability Domain
We formed a composite measure of the cognitive domain visuospatial ability, aka perceptual orientation, by converting raw scores on each cognitive test to z scores, using the mean and standard deviation of the cohort, and then averaging the z-scores to yield the composite.
The following 2 cognitive tests are used to compute this score:
| Test score | Z-score | Cognitive test name |
|---|---|---|
| cts_lopair | z_LOpair | Line orientation |
| cts_pmat | z_PMat | Progressive matrices (16 items) |
Item level variables are available upon request.
Note: The variable is calculated if more than half the z-scores are non-missing.
