A time-based example would be remembering to watch TV at 8pm, or recalling a meeting or appointment at a certain time. Two such neglected memory systems are those of prospective memory (PM) and retrospective memory (RM), with evidence being particularly lacking for both memory systems in the case of adults with dyslexia.
