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 different speeds and the individual indicates 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, 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. Available to qualified professionals without charge for a limited time.

The Bicycle Drawing Test (BDT) Revised 2019

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. 

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 an organized and thorough method of assessing visuomotor ability that is not typically available in drawing or copying tests. The Mechanical Reasoning section aids in assessing complex nonverbal reasoning. The new copy phase helps to compare a drawing from memory to one where the drawer has a model of a bicycle to copy.
