The Tens Test (c) is an eight-minute audio test that presents the same group of spoken digits at three different speeds and the individual must quickly indicate when two adjacent numbers add to 10. There are 45 correct targets. Errors are scored for Omissions (inattention) and Commissions (impulsivity or confusion).
Assessing attention is important for patients with neurologic disease, concussion, traumatic brain injury, and ADHD, and for research (e.g., pharmacological studies). Information processing may be an early sign of dementia (Apolipoprotein E-e4, Processing Speed, and White Matter Volume in a Genetically Enriched Sample of Midlife Adults) so its inclusion in an assessment is recommended. The Tens Test is intended for individuals from teenagers through adulthood, especially patients who may have difficulty tolerating stressful sustained attention tests such as the PASAT.
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. More information about the Tens Test is presented in the manual (click the icon above to access the manual).
NEW scoring spreadsheet (version 2.93) and scoring form are available.
Bicycle Drawing Test
The Bicycle Drawing Test (BDT) offers an organized method of assessing visuomotor ability with a real object - which is not typically done in neuropsychological drawing or design copying tests. This scoring system offers the opportunity to assess not only visuospatial abilities but also higher-level nonverbal reasoning using the Mechanical Reasoning component of the scoring system. The copy phase helps to compare a drawing from memory to one where the drawer has a model of a bicycle to copy.
The Bicycle Drawing Test (BDT) is a revision of the scoring system described in Lezak's book (Revised Scoring, Reliability, and Validity Investigations of Piaget's Bicycle Drawing Test, Assessment March 1994 vol. 1 no. 1 89-101) with a new copy option. Research on this system has found it helpful in assessing both child and adult bicycle drawings.
A drawing of a bicycle from memory is first done and scored using the categories:
-
Parts and Complexity
-
Motor Control
-
Spatial Relationships
-
Mechanical Reasoning
The copy phase then is administered and offers additional information about drawing capabilities. Adult norms are presently available for the BDT Memory and Copy phases. There is a Compulsivity / Effort Index to aid in assessing performance validity for the BDT Copy.
