Abstract: A method to be performed on a computer for neuropsychological evaluation of a person includes calculating complexities of a plurality of stimuli by a pattern description length algorithm for a pattern of each the stimulus, presenting stimuli to the user in reaction to which the user has to perform a cognitive test, the stimuli being presented in order of complexity and adjusting a complexity level for a next cognitive test based on the user's response.

Abstract: A system for performing neurological and/or psychological tests includes a test editor to generate test scripts, a testing unit to run tests using the test scripts, and an analyzer to analyze the results. The units communicate through a network and store their output in a test database. The testing unit modifies the test according at least to at least one reaction time of a subject. The test editor includes a unit having at least one stimulus-response pair defined therein, an editing unit for a test designer to create a test listing from the at least one stimulus-response pair and a script generator to generate a test script from the test listing. The analyzer analyzes spatial motion, both of the cursor movement and of the fingers as they move across the keyboard.
