Table 3.

Performances (mean (SD) Min–Max) in event-based prospective memory tasks. Times are in milliseconds and accuracy in percentage of correct answers. Significant differences between patients and controls appear in bold font. RT: reaction times; PM: prospective memory; ‘OGonly’: performance in ongoing task trials in the phase where they performed alone (before a prospective memory instruction has been given); ‘OGPM’: performance in ongoing task trials in the phase where they are mixed with PM task; ‘PM trials’: only performance in prospective memory trials is considered.
