Developed to be free from the influence of language and cultural bias, the CTT assesses sustained attention in adults.Note. Stopwatch is required for administration. Form A is the standard test form on which normative data were collected and that should be used for clinical evaluation. Forms B, C, and D should be used for research. A comprehensive list of research articles related to the CTT and CCTT is available via Mendeley, a free reference management tool. After accessing the link, you will be prompted to create an account. A white paper describing how to use this research repository can be found here. Use of this resource is encouraged to facilitate research using the CTT and CCTT products. Both the list and the white paper are available in the Resources tab above.
