ABSTRACT
An enhanced role and autonomy of perception are prominent in autism. Furthermore, savant abilities, absolute pitch, and synesthesia are all more commonly found in autistic individuals than in the typical population. The mechanism of veridical mapping has been proposed to account for how enhanced perception in autism leads to the high prevalence of these three phenomena and their structural similarity. Veridical mapping entails functional rededication of perceptual brain regions to higher order cognitive operations, allowing the enhanced detection and memorization of isomorphisms between perceptual and non-perceptual structures across multiple scales. In this paper, we present FC, an autistic individual who possesses several savant abilities in addition to both absolute pitch and synesthesia-like associations. The co-occurrence in FC of abilities, some of them rare, which share the same structure, as well as FC's own accounts of their development, together suggest the importance of veridical mapping in the atypical range and nature of abilities displayed by autistic people.

FC’s representation of numbers according two specific categories: kindness (nice, or “gentil”/ not nice, or “pas gentil”) and mattering (it matters, or “grave”/it does not matter, or “pas grave”).

Figure 2: FC’s representation of numbers according two specific categories: kindness (nice, or “gentil”/ not nice, or “pas gentil”) and mattering (it matters, or “grave”/it does not matter, or “pas grave”).

Mentions: When questioned about the month/emotion correspondence, FC explained that “January is very very bad, February is very bad, March is bad, April is good, May is very good, and June is very very good.” When asked about the number/emotion correspondence, FC reported that some numbers can be “nice or not nice” or that they can “matter or not matter.” In addition, the evocation (or the vision) of certain numbers cause him a physical sensation, as sometimes he reacted to certain numbers as though to a tickle, according to his parents and to our own observations. FC spontaneously provided a graphic representation of how a subset of numbers can be classified as a function of their “kindness” (nice / not nice) and their “mattering” (matters/does not matter; see Figure 2). Thus, four categories of emotional valence emerge from FC’s classification. In order to establish a more systematic representation of FC’s categorization of numbers, we questioned him on which emotional valence (i.e., category) each number is associated with. At the beginning, numbers were asked individually and in order. After number 10, only numbers close to the categories’ boundaries were asked. A representation of the architecture of FC’s categorization is given in Table 3. FC’s synesthesia-like categories are structured by certain rules. Number of digits in each successive category is multiplied by two (between number 3–4 there are 2 digits, between number 5–8 there are 4 digits, between number 9–16 there are 8 digits, from number17–32 there are 16 digits, and so on…). Categories are presented systematically: not nice/not matter, nice/not matter, not nice/matter, nice/matter. When FC arrived at the number 8,388,608, he declared he wanted to stop.

An enhanced role and autonomy of perception are prominent in autism. Furthermore, savant abilities, absolute pitch, and synesthesia are all more commonly found in autistic individuals than in the typical population. The mechanism of veridical mapping has been proposed to account for how enhanced perception in autism leads to the high prevalence of these three phenomena and their structural similarity. Veridical mapping entails functional rededication of perceptual brain regions to higher order cognitive operations, allowing the enhanced detection and memorization of isomorphisms between perceptual and non-perceptual structures across multiple scales. In this paper, we present FC, an autistic individual who possesses several savant abilities in addition to both absolute pitch and synesthesia-like associations. The co-occurrence in FC of abilities, some of them rare, which share the same structure, as well as FC's own accounts of their development, together suggest the importance of veridical mapping in the atypical range and nature of abilities displayed by autistic people.
