Separate mechanisms for number reading and word reading: Evidence from selective impairments
2019, CortexCitation Excerpt :Disorders of word reading sometimes spare number reading (Anderson, Damasio, & Damasio, 1990; Cohen & Dehaene, 1995; Friedmann & Nachman-Katz, 2004; Friedmann, Dotan, & Rahamim, 2010; Greenblatt, 1973; Hécaen & Kremin, 1976; Leff et al., 2001; Lühdorf & Paulson, 1977; Nachman-Katz & Friedmann, 2007; Sakurai, Yagishita, Goto, Ohtsu, & Mannen, 2006; Starrfelt, 2007; Temple, 2006), and disorders of written word comprehension sometimes spare the comprehension of written digit strings (Cohen & Dehaene, 2000; Dalmás & Dansilio, 2000; Ingles & Eskes, 2008; Miozzo & Caramazza, 1998; but some such dissociations were criticized as statistically unconvincing, Starrfelt & Behrmann, 2011). The opposite dissociation was also reported: disorders of number reading sometimes spare word reading (Basso & Beschin, 2000; Cipolotti, 1995; Cipolotti, Warrington, & Butterworth, 1995; Marangolo, Nasti, & Zorzi, 2004; Priftis, Albanese, Meneghello, & Pitteri, 2013; Temple, 1989). Word reading and number reading also give rise to different brain activation patterns (Carreiras, Monahan, Lizarazu, Duñabeitia, & Molinaro, 2015; Carreiras, Quiñones, Hernández-Cabrera, & Duñabeitia, 2015; Hannagan et al., 2015; Roux, Lubrano, Lauwers-Cances, Giussani, & Démonet, 2008; Shum et al., 2013).
Neural correlates of quantity processing of Chinese numeral classifiers
2018, Brain and LanguageCitation Excerpt :Cipolotti et al. (1995) reported an acalculic patient who was able to read letters, words, and number words but not Arabic numbers, suggesting that number processing is notation-dependent. Notably, Cipolotti et al. (1995) also found that the patient’s knowledge of cardinal value of Arabic numbers was intact in magnitude comparison tasks. This suggested that although the number processing is notation-dependent, the processing of semantic quantity may not be notation-dependent.
Numbers and functional lateralization: A visual half-field and dichotic listening study in proficient bilinguals
2017, NeuropsychologiaCitation Excerpt :Our study, therefore, shows that the relations between complex language, single words and numbers are much more complex than previously thought (Gelman and Butterworth, 2005). Note that it is often underlined that language can in a sense block the processing of numbers (Cipolotti et al., 1991; Cipolotti et al., 1995; Dehaene and Cohen, 1997) or vice versa, that processing of numbers can block language, as often demonstrated by mathematical savants with exceptional immediate counting skills (but poor language command, Pring and Hermelin, 2002; Corrigan et al., 2012; cf. Snyder et al., 2006). It is probably not the language per se that is to blame for blocking number processing in healthy individuals.
