The TVPS-4 now includes 18 items in each of seven perceptual areas. Ceilings minimize fatigue and ensure that more difficult items do not unduly tax younger students, while allowing for reliable and accurate assessment across the age range. The TVPS-4 is consistent with current methods of visual information processing used in occupational therapy and optometry.
The TVPS-4 also measures the following Cattell-Horm-Carroll theory narrow abilities:
- Flexibility of Closure
- Visual Memory
