Immediate Memory Task/Delayed Memory Task

Abbreviation

IMT/DMT

Description

The IMT/DMT (Dougherty, Marsh, & Mathias, 2002) is a continuous performance test that was designed to assess impulsive behavior. The Immediate Memory Task involves comparison of consecutively presented numbers and responding in those instances when the current number matches the number immediately before it (called a correct detection). The Delayed Memory Task similarly involves responding to matching numbers, but the numbers to be compared are separated by a filler sequence (e.g. 12345).
