Abstract/Summary Prospective memory (PM) is the process of forming future intentions and later remembering to execute those intentions at the appropriate juncture. The literature particularly highlights two different types of PM – time-based (TBPM) and event-based (EBPM). Both types of PM are critical for independent living, as they enable an individual to perform important everyday tasks, such as remembering to take medication at breakfast (EBPM), or attend a doctor’s appointment at a particular time (TBPM). Although empirical studies consistently indicate that people diagnosed with schizophrenia experience significant difficulties with PM, there is ongoing controversy as to whether TBPM and EBPM are differentially impaired. Further clouding this is that conventional PM measures may not be accurately assessing pure TBPM as they involve providing participants with a clock to gauge time, which is technically an event-based cue. To address this methodological concern, Redshaw, Suddendorf and Henry (2013) recently developed a novel measure for children that assesses TBPM, both with and without an event-based cue. After modifying this paradigm to be appropriate for adult populations, and to additionally assess EBPM, it was administered to participants diagnosed with schizophrenia (n = 22) and a matched non-clinical control group (n = 31). The results revealed individuals with schizophrenia were not impaired on this novel PM task, relative to controls. These findings are discussed in relation to the theoretical frameworks and past research in both the broader PM (normative ageing) and schizophrenia literature.
