COGTEL

Main references: Haas et al., 2021 (eCOGTEL); Kliegel et al., 2007.

A practical and rapid tool that allows assessing cognitive functioning in a global perspective: short- and long-term memory, working memory, prospective memory, verbal fluency, inductive reasoning. It takes 20 to 30 minutes to administer and provides detailed results (overall score and scores per sub-domain).

In its most recent update, we have developed an online version — the eCOGTEL — that allows for a remote, self-administered assessment of cognitive functioning (for details, see Haas et al., 2021).

You can download detailed instructions manuals below (PDF):

A free demo version of the eCOGTEL (in French) can be found here.
