Delis-Kaplan Executive Function System™

Trail Making Test (TMT)

TMT applies the process approach to the assessment of cognitive flexibility. The TMT differentiates deficits in visual scanning, mental sequencing, and motor speed/control from deficits in cognitive flexibility and control. The TMT consists of 5 trials, visual scanning, number sequencing, letter sequencing, number-letter switching, and motor speed.

Verbal Fluency (VF)

VF measures multiple aspects of verbal behavioral productivity and cognitive flexibility. It evaluates effectiveness of novel and semantic search strategies, and assesses flexibility in the implementation of semantic search strategies. The process approach enables further evaluation of self-monitoring of information search, as well as difficulties related to initiation and sustaining effort. There are three conditions in the VF test in which the examinee must say as many words as they can by letter, category, and category switching prompts.

Design Fluency (DF)

DF measures multiple aspects of visual behavioral productivity and cognitive flexibility. DF evaluates visual productivity with and without distracting stimuli, and switching between stimuli. The process approach is used to assess for difficulties with self-monitoring of performance for rule-adherence, and redundant responding. There are three conditions in the DF test in which the examinee attempts to produce as many novel designs as possible using filled, empty, or switching between filled and empty dot.

Color Word Interference Test (CWIT)

CWIT measures inhibitory control and cognitive flexibility. The CWIT utilizes the “Stroop Effect” to identify deficits in inhibition of over-learned behaviors. In addition to standard color naming, word reading, and color-word interference trials, the CWIT has an additional trial requiring the examinee to switch between inhibitory and non-inhibitory responses. Process measures enable assessment of general difficulties.
