No Innate Number Line in the Human Brain (2011, background): “…al., 2008a) and, more specifically, that numbers are represented in the human brain in the form of a mental number line (MNL) (Dehaene et al., 2003; Zorzi et al., 2002), being oriented left-to-right and localized bilaterally in the intraparietal sulcus (Priftis, Zorzi, Meneghello, Marenzi, &…”
Spatial and visual working memory ability in children with difficulties in arithmetic word problem solving (2010, background): “Moreover, examination of the literature on neuropsychological deficits in adults clearly reveals that spatial abilities are relevant for mathematics performance (Grana, Hofer, & Semenza, 2006 ; Zorzi, Priftis, & Umilta, 2002 ).”
Distributed and overlapping cerebral representations of number, size, and luminance during comparative judgments. (2004, positive): “In fMRI, relative to rest, the four tasks led to a set of activations in bilateral occipitotemporal, parietal, and brain-lesioned patients (Zorzi et al., 2002).”
The hunt for SNARC (2005, background): “Zorzi et al. (2002) extended this effect to the number field by showing that these patients also show a rightward bias in doing a number interval bisection task.”
Arithmetic and the brain. (2004, neutral): “Nevertheless, it is currently questioned whether or not this dichotomy suffices to account for the range of acalculia patients that have been reported: some cases strongly support the notion of an internal number-line [26 ] and of quantity- versus language-dependent operations [27–29], whereas other”
Short-Term Memory, Working Memory, and Executive Functioning in Preschoolers: Longitudinal Predictors of Mathematical Achievement at Age 7 Years (2008, background): “The visual-spatial system also supports other aspects of non-verbal numerical processing such as number magnitude, estimation, and representing information in a spatial form, as in a mental number line ( Dehaene, 1997 ; Dehaene, Spelke, Pinel, Stanescu, & Tsivkin, 1999 ; Zorzi, Proftis, & Umilta, ”
Mathematics and Learning Disabilities (2004, background): “Indeed, Zorzi et al. (2002) found that individuals with an injury to the right parietal cortex showed a deficit in spatial orientation and a deficit in the ability to generate and use a mental number line.”
On the Cognitive Link between Space and Number: A Meta-Analysis of the SNARC Effect (2008, background): “Although the polarity correspondence account offers a parsimonious explanation for the SNARC effect in speeded binary classification tasks, some new evidence from cognitive neuropsychology lends support to the existence and relevance of a mental number line for the formation of spatial numerical ass”
Handbook of mathematical cognition (2004, background): “In the first study, Zorzi et al. (2002) observed a systematic representation-based midpoint shift toward the right in a number interval bisection task.”
Cognitive mechanisms underlying achievement deficits in children with mathematical learning disability. (2007, background): “Our follow-up longitudinal assessments will reveal whether the number line estimates for children with MLD are normal but delayed, or whether a more fundamental deficit exists in this competency and possibly the underlying visuospatial system (Zorzi et al., 2002).”
Numerical development: current issues and future perspectives (2005, background): “Interestingly, disturbances in the mental number line representation of adult neglect patients were reported by Zorzi et al. (2002) who found that neglect patients were unable to perform a number bisection task.”
