Tests

The Tens Test 

The Tens Test is a sensitive test of auditory sustained and selective attention. It is an eight-minute audio test that presents the same group of spoken digits at three speeds and the individual must indicate when two adjacent numbers add to 10. Errors are scored for Omissions (Inattention) and Commissions (Impulsivity). It is intended for the teenage, adult or elderly patient who may have problems tolerating similar but stressful tests such as the PASAT. Assessing attention is important for patients with neurologic disease, concussion and traumatic brain injury, ADHD, and for research purposes (including pharmacological research). Information processing of this type is often neglected when assessing dementia - which may be an early sign of the disease (Apolipoprotein E-e4, Processing Speed, and While Matter Volume in a Genetically Enriched Sample of Midlife Adults).

The Tens Test is less correlated with math ability than the PASAT. In a study with MS patients the Tens Test correlated with the number of enhancing brain lesions. 

A scoring form and manual with reliability, validity data and norms is available. Free for a limited time.

The Bicycle Drawing Test (BDT) Revised  NEW for 2018.

The BDT has been revised for 2018. If you are interested in participating in development and norming of the revised BDT please contact PRT.

The BDT is based on the scoring system by Greenberg et al. (1994) (Revised Scoring, Reliability, and Validity Investigations of Piaget's Bicycle Drawing Test, Assessment March 1994 vol. 1 no. 1 89-101) with a recently added copy phase. The 2018 scoring revision is now available (the manual will follow sometime in 2018).

A drawing from memory is first done and scored using the categories of: 

  • Parts and Complexity
  • Motor Control
  • Spatial Relationships
  • Mechanical Reasoning

The BDT offers a more organized and thorough method of assessing visuomotor ability, and with the Mechanical Reasoning section it can aid in assessing complex nonverbal reasoning. A copy phase helps to compare a drawing from memory and from copy (with model). The 2018 revised scoring systems are available now (i.e., model from memory and for copying). Click below to download the BDT scoring forms. The manual will be available later in 2018. Contact PRT for a manual draft.
