I require some Windows based software, based on the AX-CPT psychological test.

The test is a means of measuring sustained attention.

The test consists of a series of random letters that appear successively on a blank screen. The participant is instructed to click a corresponding mouse button depending on whether the letter is a target or a non-target.

A target consists of the letter "X" that has been preceded by an "A" as the first letter in a four letter string, for example the "X" in this string (A,F,U,X) would constitute a target. The participant should only click the right mouse button on the completion of a target four left string. In the example above the participant should click "left Mouse button, left mouse button, left mouse button, right mouse button". Examples of targets:

"A,J,I,X"

"A,T,S,X"

"A,Z,P,X"

Any other combination, for example:

"T,Y,F,I"

"Y,O,P,I"

"A,H,Y,S"

"G,A,O,X"

"Q,T,A,X"

Does not constitute a target, and as such the participant should respond with the following "left mouse button, left mouse button, left mouse button, left mouse button".

The participants responses should be recorded in the following way:

If the participant correctly identifies a non-target letter with a left click, this is recorded under "correct non-target"

If the participant incorrectly identifies a non-target letter with a right click, this is recorded under "incorrect non-target" and a noise is emitted to notify the participant that they have responded incorrectly.

If the participant correctly identifies a target letter with a right click, this is recorded under "correct target"

If the participant incorrectly identifies a target letter with a left click, this is recorded under "incorrect target" and a noise is emitted to notify the participant that they have responded incorrectly.

On completion of the test a table is to be produced listing the number of responses that was recorded in each of the four outcomes listed above.

On starting the software, it must allow the following variables:

[url removed, login to view] length of test must be adjustable between 1 minute and 99 minutes

2. Time period between the appearance of random letters must be adjustable between 0.1 - 1 seconds.

3. The frequency of a target string must be adjustable between 0-100%

4. The size of the font is to be adjustable.

The appearance of the screen is to be black with white text.

Upon maximising the software window the only thing visible is the test and not windows (i.e. the task bar is not to be visible).

The test is to stop and the screen minimise on the pressing of the "Esc" key.
