The test battery is designed to use in clinical practice for diagnosis of cognitive functions, especially in MCI and dementia patients. It offers a wide range of tests that address different cognitive domains. It helps in the identification and management of memory problems as well as other disorders affecting cognitive function. It may also be a great tool to be used in researches.
Test 1.
Description
There are six different versions of this memory test with varying number's of total stimuli including: items of daily living, pictures of everyday life objects, digits, nonrealistic symbols, words and pictures.
Design
A set of visual stimuli is presented to the participant. After the stimulus set is displayed, the participant is asked to recall as many visual stimuli from the set as he or she can remember, in any order.
Administration
The task is administered via the computer screen, and subject's responses are verbal.
Response recording/results
The total number of correct and incorrect responses is recorded along with intrusions and perseveration errors.
Test 2.
Description
There are six different version's of this delayed memory recall task corresponding to the six versions of the memory test (Test 1).
Design
Participant is asked to recall as many visual stimuli from the set as he or she can remember, in any order.
Administration
The task is administered via the computer screen, and subject's responses are verbal.
Response recording/results
The total number of correct and incorrect responses is recorded along with intrusions and perseveration errors.
Test 3.
Description
There are six different version's of this Recognition task corresponding to the six versions of the memory test (Test 1)
Design
A visual stimulus is displayed randomly from the original set or the distractor set. For each stimulus, the participant has to decide whether s/he saw it before and respond by pressing the yes or no button.
Administration
The task is administered via the computer screen, and subject's responses are verbal.
Response recording/results
The total number of correct and incorrect responses is measured.
Test 4.
Description
This test measures the visual spatial working memory. There are eight different version's of this test with varying number of total stimuli including: rounded figures, geometric figures, abstract patterns, picture graphics, pictures of everyday life objects, digits, nonrealistic symbols and words.
Design
Participant is shown n increasing number of boxes randomly displayed on the computer screen. The task begins by the computer uncovering each box sequentially, for an exposure of the design underneath. The task for the participant is to recall where each design is located. The increasing number of stimuli is designed to control the influence of working memory span on results.
Administration
The task is administered via the computer screen, and subject's responses are through the use of the mouse or touch screen.
Response recording/results
The number of correct, incorrect and timed out responses and reaction times are measured.
Test 5.
Description
This test measures sustained attention, cognitive inhibition and discrimination abilities. It is based on continuous performance paradigm.
Design
Participant is instructed to respond with a right key press whenever the target stimulus proceeded by a particular distractor stimulus appears on the screen. The left key is pressed for all other stimuli, including the particular distractor stimulus, the target stimulus that was not preceded by the particular distractor stimulus, or any other stimulus. Practice trials are given and the participant is trained in the correct performance of the test before formal testing is initiated.
Administration
The task is administered via the computer screen, and subject responses are through the use of the keyboard.
Response recording/results
The number of correct and incorrect responses and reaction times are measured.
Test 6.
Description
This task is designed to measure working memory using a non-verbal stimuli.
Design
A group of stars in a semi-random arrangement are presented on the screen, and a sequence of stars will light up by changing to red color. Participant's task is to click on the same stars, in the same sequence (or, in the case of backwards span, in reverse sequence).
Administration
The task is administered via the computer screen, and subject responses are through the use of the mouse or touch screen.
Response recording/results
The total number correct, longest correct, number attempted but failed and median response time per item for forward and backward span are measured.
Test 7.
Description
This test is based on go/no-go paradigm. It assesses sustained attention and response control.
Design
Participant is asked to respond by pressing a spacebar while given certain stimuli (GO response) and inhibit that response under a different set of stimuli (NO-GO response). All the stimuli are visual (1 stimulus for GO and NO-GO responses). Practice trials are given and the participant is trained in the correct performance of the test before formal testing is initiated.
Administration
The task is administered via the computer screen, and subject responses are through the use of the keyboard.
Response recording/results
The number of correct and incorrect responses, as well as reaction times for all GO and NO-GO responses are measured.
Test 8.
Description
This test is based on the Stroop Effect used to measure attention and executive function. It also assesses the flexibility of thinking.
Design
Participant task is to adapt his responses to changing rules of test
Administration
The task is administered via the computer screen, and subject responses are through the use of the keyboard.
Response recording/results
The number of correct and incorrect responses and reaction times are measured.
Test 9.
Description
This test assesses visual spatial abilities and processing speed.
Design
Participant task is to solve the maze. There is an option to choose left or right oriented maze. This test has five different versions of the maze. The complexity of maze increases from first to the fifth version.
Administration
The task is administered via the computer screen, and subject responses are through the use of the mouse or touch screen.
Response recording/results
The total time of completion is recorded.
Test 10.
Description
This test measures psychomotor speed, visual spatial working memory and executive function. It is based on TMT design.
Design
Participant task is to connect digits and alphabets in increasing sequence. There are two versions of this test. In the first version only digits are used and in the second version both digits and alphabets are used.
Administration
The task is administered via the computer screen, and subject responses are through the use of the mouse or touch screen.
Response recording/results
The total time elapsed is recorded.
Test 11.
Description
This test measures abstract reasoning
Design
Participant is presented with four pictures on the screen, three of them belong to the same category or group and one does not. The participant task is to identify the picture that does not belong to the same category or group.
Administration
The task is administered via the computer screen, and subject responses are through the use of the mouse or touch screen.
Response recording/results
The number of correct and incorrect responses and reaction times are measured.
Test 12.
