Picture arrangement test is a test that consists of a series of comic-strip-like pictures that are presented in a random order. The subject is given the task to arrange the pictures as quickly as possible so that a reasonable and meaningful story is formed. This is an example of a common feature found in intelligence tests. As the demand for psychological testing has increased, this type has seen increased use throughout Psychology. There are several different ways and scales that can be used with this test to measure different kind of intelligence. Different tests over time have been created to measure different things. One scale that has been developed and used with these tests has been the Wechsler Adult Intelligence Scale which breaks down ones full performance IQ into subsets like verbal IQ and performance IQ, getting more specific and elaborate as the scale for each individual develops. The reliability of this test has been disputed, however. For example, patients with schizophrenia have been found to score as more "normal" than patients with no such mental disorders.
