(2002). Immediate and Delayed Memory Tasks: A computerized measure of memory, attention, and impulsivity. Behavior Research Methods, Instruments, and Computers, 34, 391-398. The IMT/DMT was developed to support the systematic study of sustained attention, working memory, and impulsivity in higher functioning populations. It provides an alternative to the Continuous Performance Test (CPT). ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants view a steady stream of 5-digit (default) numbers and are asked to click the Mouse button if the current target number is identical to the one before it. 2 slightly different conditions: A) Delayed: the target numbers are followed by three distractor numbers.
