This script implements a practice + testing session for the Immediate & Delayed Memory Task (IMT/DMT) described in:
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.
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).
Immediate & Delayed Memory Task (Imt/Dmt) - Practice Session
Immediate & Delayed Memory Task (Imt/Dmt) - Testing Session
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)
