The Tens Test
A test of sustained and selective auditory concentration
The Tens Test (c) is an eight-minute auditory assessment that presents a sequence of spoken digits at three increasingly faster speeds (1.8, 1.4 and 1.0 seconds). The individual is required to promptly identify when they hear two consecutive digits that sum to ten. The test has 45 correct targets (i.e., the same 15 targets in each interval). Raw scores are the number of correct identifications (attentional capacity), and commission errors (indicative of impulsivity or confusion). A free scoring spreadsheet analyses the performance.
Evaluating concentration is important when evaluating patients with neurological disorders, concussion, traumatic brain injury, and ADHD. Attention processing impairment may be an early indicator of dementia (https://pubmed.ncbi.nlm.nih.gov/21937476/), making its inclusion in dementia assessments valuable. Moreover, the Tens Test can be useful in research applications (e.g., pharmacological studies of individuals with cognitive disorders).
The Tens Test is an assessment tool suitable for individuals spanning adolescence to adulthood. It serves as an alternative to the very stressful PASAT. Moreover, the Tens Test exhibits a lower correlation with mathematical aptitude compared to the PASAT. A study conducted among individuals with multiple sclerosis demonstrated that the Tens Test correlated with the number of enhancing brain lesions.
Further information regarding the Tens Test is provided in the manual.
Bicycle Drawing Test
The Bicycle Drawing Test (BDT) is a research instrument that employs a systematic methodology for assessing visuomotor capabilities using a real object. The scoring system evaluates not only visuospatial abilities but also higher-order nonverbal reasoning through the Mechanical Reasoning component. 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 version 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 administered to offer extra insights into drawing skills. A Compulsivity/Effort Index is included to help evaluate the performance validity of the BDT Copy. Adult norms are available for the BDT Memory and Copy phases.
