This recognition memory test uses pictures or images of everyday objects. First, an individual is shown a series of pictures and asked to identify each one. This step assesses the basic ability of the individual to participate in the test. The next step is to test the immediate recognition memory of the individual by showing a series of pictures with distracter pictures mixed in. The challenge is to identify each original picture among the distracters. The final step is to wait for a period of time and then re-test the individual with the series of pictures containing distracter pictures. This step tests the delayed recognition memory. This system can be used to test the recognition memory of individuals with moderate to severe mental retardation due to its simplicity over current memory tests, which are often too challenging to yield conclusive results in these populations. Additionally, the test may be used as a dementia screening tool to identify those with dementia from no other apparent cause, which may help identify individuals in the early stages of Alzheimer’s disease.
