CTT is a neuropsychological test to examine several attention and executive functions especially perceptual tracking, sustained and divided attention, sequencing and self-monitoring. Graphomotor skills are also involved.
The CTT is a new version of the Trail Making Test, where the letter stimuli are substituted with colors. It consists of two parts, CTT-1 and CTT-2, administered consecutively. Each part contains pink and yellow circles with numbers from 1 to 25. The subject connects circles numbered 1 through 25 in sequence using straight lines, but alternates between pink and yellow colors for the CTT-2. The examination part is interrupted after 240 seconds. CTT exists in four forms (A, B, C, D)which enable to conduct longitudinal research. The main indexes are the completion times registered separately for CTT-1 and CTT-2. Number sequence & color errors, near-misses, corrections and prompts are also examined. An Interference Index informs about the lengthening of CTT- 2 time score in comparison to CTT-1. Approximate score computing time – 10 minutes.

Norms
For people aged 18–69 (all-Poland sample).
