Prospective memory, also referred to as memory for intentions, is the ability to remember to carry out a future task. It has been linked to poor medical adherence and poor functional outcomes. The MIST, a test of eight time-delayed prospective memory tasks, separates itself from other prospective memory tests by including multidimensional tasks, analyzing the types of skills that may compromise performance, and being appropriate for individuals with neurological disorders.

Tasks were designed to measure the everyday aspects of prospective memory performance

  • Each MIST task is a real-world task that one might have to perform in daily life.
  • MIST trials vary by cue type (time vs. event), time delay (long vs. short), and response type (action vs. verbal).
  • A Delayed Prospective Memory Task with a 24-hour delay enables you to approximate the examinee’s time span of actual memory for intentions in daily life.
  • Each task includes a delay between encoding and retrieval and is performed amid a separate ongoing activity. No explicit prompt is given when the occasion to act occurs.
  • Five types of errors can be analyzed: prospective memory failure errors, task substitution errors, loss of content errors, loss of time errors, and random errors.
  • Two forms mitigate practice effects.
  • To evaluate retrospective memory functioning, a series of multiple-choice recognition items given at the end of the testing session query the participant on the specific tasks were presented during the test.
  • The MIST has been studied in many clinical populations, including multiple sclerosis, schizophrenia, Parkinson’s disease, and more.
