Results of comparisons of non-users', experimenters', and chronic users' prospective memory.

Note: bold indicates p≤.01. Groups with different subscripts differed significantly. PMQ = Prospective Memory Questionnaire; PRMQ = Prospective and Retrospective Memory Questionnaire; TCPMQ = Time−Cued Prospective Memory Questionnaire. Higher scores on the prospective memory questionnaires indicate more frequent prospective memory failures or greater use of memory aiding strategies. Scores of 3 on the TCPMQ punctuality subscale reflect on-time performance, scores below 3 indicate early performance and scores above 3 indicate late performance. Higher scores on the Fruit Prospective Memory Test indicate better performance.
