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).
This script implements a practice + testing session for the Immediate & Delayed Memory Task (IMT/DMT) described in: Dougherty et al (2002).
Dougherty, D.M., Marsh, D.M., and Mathias, C.W. (2002). Immediate and Delayed Memory Tasks: A computerized measure of memory, attention, and impulsivity. Behavior Research Methods, Instruments, and Computers, 34, 391-398.
30 minutes
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. The distractor numbers are always the same number (12345). B) Immediate: target numbers follow target numbers immediately. No distractors are used.
This batch script runs (1) imtdmt_practice.iqjs (instructions + practice) (2) imtdmt_test.iqjs (test session)
