This topic became interesting to me after reading through unit one of this course. I began to think about all other ways that I confront challenges in day-to-day situations that have yet to be measured on a standardized test. Further light was shed on this topic when one considers disabled individuals who would not perform well within a certain testing format, but might excel at others. 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. They chose two institutions in which to get their samples from. It consisted of 67 men and 44 women. The groups were divided into three disability groups ranging from mild, moderate, to severe (whatever status was designated on their ID by the government.)
The research method used to collect the data involved many processes. First there was a standard measurement to measure, mean, median and mode relative to percentiles of individuals who have taken the test prior. They also used
