The Tens Test (c) is an eight-minute auditory assessment that presents a sequence of spoken digits at three distinct speeds. The participant is required to promptly identify instances where two consecutive digits sum to ten. The test comprises 45 correct targets, and errors are categorized as omissions (indicative of inattention) or commissions (suggesting impulsivity or confusion).
Evaluating attention is crucial for patients with neurological disorders, concussion, traumatic brain injury, and ADHD, as well as for research purposes, particularly in 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 designed for individuals aged between adolescence and adulthood, particularly those who may encounter challenges in sustaining attention during prolonged and stressful tests, such as the PASAT.
The Tens Test exhibits a lower correlation with mathematical aptitude compared to the PASAT. A study conducted among individuals with multiple sclerosis revealed that the Tens Test correlated with the count of enhancing brain lesions. Further details regarding the Tens Test are provided in the accompanying manual (accessible by clicking the icon above).

Bicycle Drawing Test
The Bicycle Drawing Test (BDT) provides a structured approach to evaluating visuomotor capabilities using a real object, which is not commonly employed in neuropsychological drawing or design copying assessments. This scoring system facilitates the assessment of not only visuospatial abilities but also higher-order nonverbal reasoning through the Mechanical Reasoning component of the scoring system. The copying phase facilitates the comparison of a drawing produced from memory to one where the drawer has a model of a bicycle to replicate.
The Bicycle Drawing Test (BDT) is a revised scoring system, as 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). This system includes a new copy option. Research conducted on this system has demonstrated its effectiveness 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 is then administered and provides additional information regarding drawing capabilities. Adult norms are currently available for the BDT Memory and Copy phases. A Compulsivity / Effort Index is available to assist in assessing the validity of performance for the BDT Copy.
