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.
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
B) Immediate: target numbers follow target numbers immediately. No distractors are used.
This batch script runs
(1) IMTDMT_practice.iqx (instructions + practice)
(2) IMTDMT_test.iqx (test session)
