56| The D-KEFS, D-KEFS 2.0, and CVLT-3 – A Conversation With Dr. Dean Delis

There are several hallmark assessments of memory and higher-level cognitive functions that are commonly used and recognized by neuropsychologists.  Among these are the Delis-Kaplan Executive Function System (D-KEFS) and the California Verbal Learning Test (CVLT), which were developed by Dr. Dean Delis, a board-certified neuropsychologist.  Today, we talk with Dean about executive functions, the D-KEFS, the upcoming D-KEFS 2.0, and the CVLT-3.

  1. This was a fantastic episode and this podcast is great overall. I’m so excited for the DKEFS2, and I’m curious to see what additions have been made. Dr. Delis’s comments about verbal switching were really interesting and I’m curious if there will be any action fluency items on the new version. Thanks for the great show!
