Again the tests are crucial for identification and management of dementia. Although it is true that older adults commonly suffer from optical impairment, little research has been done to establish the influence that this type of impairment has on cognitive test performance. Moreover, the screening tests that are most commonly used for detection of dementia usually rely on vision. Studies conducted in this field have repeatedly proved that researchers and clinicians are required to take into consideration the visual demands of these cognitive tests utilized in research and clinical findings.
Significance and Factors affecting Cognitive Visual Test Automation
Computerized assessment is one of the best methods to utilize for early detection of alterations in cognition. Computer tests are offered in a standardized format, take into account a wide range of capabilities and help in recording the accuracy and speed of response with a sensitivity level that is not feasible in other standard administrations.
These characteristics are extremely essential for early detection as well as for extending the test range to be sensitive to MCI as well as to the other increasingly pronounced alterations taking place in the initial stages of dementia. When compared with conventional neuropsychological assessment instruments, automated tests also represent a prospective cost saving, with respect to the supplies and materials as well as the time required by the test administrator.
Here are some of the factors that affect the test situations in case of a cognitive visual test automation. These factors might not be normal and might affect the person's performance so far as a particular task is concerned.
- Whether the person is able to maintain direct attention towards the test stimulus.
- Whether the motor functions for execution of the plan is available.
- Whether the visual field incorporates the test stimulus.
- Whether the position of the person concerned is not inhibiting the response.
There are manifold advantages that a computer based assessment system has to offer so far as cognitive visual test is concerned:
- Since the automated tools reduce the need for administration on behalf of the trained personnel, they make considerable room for scheduling flexibility and cost savings. In fact, there are certain batteries which are completely self-administered.
- Another striking benefit of the test batteries over conventional assessments is the flexibility offered with respect to instantaneous adjustments for performance levels. A number of batteries are capable of automatically changing the order of the tests along with the presentation rate and difficulty level.
- The level of precision offered by the automated cognitive visual tests is commendable.
