The DVT is a simple task designed to measure vigilance during rapid visual tracking and accurate selection of target stimuli. It focuses on alertness and vigilance while placing minimal demands on two other components of attention: selectivity and capacity.

Features and benefits

  • Respondents are asked to find and cross out either sixes or nines, which appear randomly within 59 rows of single digits on two separate pages.
  • Allows you to readminister with minimal practice effects.
  • Administration and scoring can be accomplished by individuals with no formal training under the supervision of a qualified psychologist. Interpretation requires training in clinical psychology or neuropsychology.

Note: Normative data are not provided in the Professional User’s guide, but are presented in the Revised Comprehensive Norms for an Expanded Halstead-Reitan Battery. Stopwatch required.
