Neuropsychological testing revealed severe deficits in all cognitive domains and poor explicit knowledge of calendar structure. The subject scored well above the chance level on dates of the past and future decades. Error rate and response latency increased with temporal remoteness of dates. Most of errors were in indicating the weekday before or after that of date stimulus. The performance and error pattern suggest that L.E. used “encapsulated” computation algorithm(s) for the day of week task.

Brief Report: Two Day-Date Processing Methods in an Autistic Savant Calendar Calculator / Matteo DE MARCO in Journal of Autism and Developmental Disorders, 46-3 (March 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-3 (March 2016) . - p.1096-1102 Titre : Brief Report: Two Day-Date Processing Methods in an Autistic Savant Calendar Calculator Type de document : Texte imprimé et/ou numérique Auteurs : Matteo DE MARCO, Auteur ; Alessandro IAVARONE, Auteur ; Giovanna SANTORO, Auteur ; Sergio CARLOMAGNO, Auteur Article en page(s) : p.1096-1102 Langues : Anglais (eng) Mots-clés : Asperger  Autism  Calendrical calculation  Memory  Algorithm Index. décimale : PER Périodiques Résumé : Special ability in computing the day of week for given dates was observed in a 24 year-old male (FB) diagnosed with Asperger syndrome. FB performed almost flawlessly (98.2 %) both with past and future dates, over a span of 40 years. Response latency was slower as temporal remoteness of future dates increased. Within the future timespan, FB’s performance was consistent with the active use of calendar regularities. On the contrary, within the past timespan (for which no remoteness effect was seen), his performance was mainly linked to memory retrieval of personal events. The case presented here complements the existent literature on calendar calculators, as, for first time, two distinct day-date processing styles are described in the same individual.
