How can familiarity with tasks affect MoCA results?

Familiarity with tasks can indeed lead to artificially higher scores on the MoCA test, which is designed to assess cognitive function. When a test-taker has prior experience with the specific tasks or types of questions presented in the MoCA, their comfort level and recognition of the patterns increase. This familiarity can result in a performance that does not accurately reflect their actual cognitive abilities, as they may be leveraging prior knowledge rather than demonstrating true cognitive processing skills.

For example, if a participant has previously encountered similar visual-spatial tasks, they may complete them more quickly or accurately than someone who is seeing them for the first time. This advantage can skew the results, making it appear as though the individual has better cognitive function than they genuinely possess. Thus, it is crucial to consider an individual's exposure to the types of materials presented in the MoCA when interpreting their scores, as this can influence their performance significantly.
