Depiction of the mean age (middle marker) and the minimum and maximum age range for each experimental group for all studies investigating prospective memory in ASD. Where possible we plotted the verbal mental age of each group onto the age distribution as marked with the grey x to illustrate the relation of chronological vs. mental age in each study. TB time-based PM only study, EB event-based PM only study, TB and EB time-based and event-based PM study, *Jones et al. (2011) did not study event-based PM per se but investigated everyday memory in ASD
