I have a great interest in exploring unknowns and find it fascinating that there is still much room for improvement when it comes to measuring intelligence.
One topic that I came across was a test that was specifically designed to measure cognitive abilities and visual perception in people with intellectual disabilities. The purpose of this article is to explore the validity of some of these tests, specifically the “LOTCA” and “Pictorial Test.” This test has also been helpful in measuring abilities in certain individuals with brain injuries.
This sample was a convenience sample which is not as strong as a random sample because every member does not have an equal chance of getting selected. The Convenience method can have some bias because it often times consists of volunteers. In this sample they chose 112 participants that were closest to their location.
