This website allows the user to enter item-level response type data from the Philadelphia Naming Test to obtain estimates of latent cognitive abilities.
Ability estimates are derived from a cognitive psychometric model of the picture naming process (Walker, Hickok, & Fridriksson, 2018).
Percentile scores are relative to a group of 365 participants with aphasia (September 2016).
