HEAVEY, Lisa, HERMELIN, Beate, CRANE, Laura and PRING, Linda (2012). The structure of savant calendrical knowledge. Developmental Medicine and Child Neurology, 54 (6), 507-513.Full text not available from this repository.
Aim - We aimed to explore the organization of the calendar knowledge base underlying date calculation by assessing the ability of savant calendar calculators to free recall a series of date lists.
Method - Four experiments are reported that assessed recall of structural and non-structural features of the calendar in eight savant calendar calculators (seven males; one female; median age 34y 6mo; age range 27–47y), five of whom had a diagnosis on the autism spectrum. The inclusion criterion was a genuine calculation ability rather than an interest in dates.
Results - Mean recall was facilitated for material organized according to the structural features of a calendar (leap years, dates falling on the same weekday, dates occurring at 28y intervals) but not for a non-structural calendar feature (Easter Sunday).
Interpretation - Distinctions are drawn between two sources of savant calendar-related knowledge, structural and event related. It has been suggested that structural knowledge plays a key role in the acquisition and operation of savant date calculation skills.
