From Wikipedia, the free encyclopedia. Cognitive tests are assessments of the cognitive capabilities of humans and other animals. Tests administered to humans include various forms of IQ tests; those administered to animals include the mirror test (a test of visual self-awareness) and the T maze test (which tests learning ability).
The MoCA tests are screening instruments used to facilitate the assessment of mild cognitive impairment. It is essential that people using the MoCA tests be trained and certified. A clinical assessment is necessary to interpret the results of the MoCA test. MoCA test results can be interpreted only by healthcare professionals with expertise in the cognitive field, including, among others, neurologists, neuropsychologists, occupational therapists and psychiatrists. The test results cannot be the only measure used to diagnose a personâs cognitive abilities.
