“…However, the control tasks used in this study involved some orientation components, which might have activated the IPS . This is in line with the suggestion that the IPS is involved in visuospatial abilities (Cohen Kadosh et al, 2007d;Fischer et al, 2003;Hubbard et al, 2005;Vuilleumier et al, 2004;Zorzi et al, 2002), which are also implicated in number processing (see the SNARC effect in Section 2.1). Therefore, it is not clear whether the lack of number-specific activation was due to controlling for response selection per se.…”

There is a current debate whether the human brain possesses a shared representation for various types of magnitude such as numerical quantities, physical size, or loudness. Here, we critically review evidence from chronometric, neuroimaging, developmental and comparative fields, and supplement it with a meta-analysis of the neuroimaging data. Together, based on such an integrative overview, we discuss limitations inherent in each approach, and the possibility whether shared, or distinct magnitude representation, or both representations exist. #

“…This task was firstly used with numbers by Fischer et al (2003), who demonstrated that the mere perception of numbers causes a spatial shift of attention (also called attentional SNARC effect). Namely, participants were faster in responding to a target appearing on the left of the screen after that a small number was presented in the centre as a prime.…”

The SNARC effect is considered an evidence of the association between numbers and space, with faster left key-press responses to small numbers and faster right key-press responses to large numbers. We examined whether visually presented note values produce a SNARClike effect. Differently from numbers, note values are represented as a decreasing left-toright progression, allowing us to disambiguate the contribution of order and magnitude in determining the direction of the effect. Musicians with formal education performed a note value comparison in Experiment 1 (direct task), a line orientation judgment in Experiment 2 (indirect task), and a detection task in Experiment 3 (indirect task). When note values were task relevant (direct task), participants responded faster to large note values with the left key-press, and vice versa. Conversely, when note values were task irrelevant (indirect tasks), the direction of this association was reversed. This evidence suggests the existence of separate mechanisms underlying the SNARC effect. Namely, an Order-Related Mechanism (ORM) and a Magnitude-Related Mechanism (MRM), that are revealed by different task demands. Indeed, according to a new model we proposed, ordinal and magnitude related information seem to be preferentially involved in direct and indirect tasks, respectively.

“…Galfano et al, 2006;Ristic et al, 2006). For instance, Fischer et al (2003) found that exposure to small numbers (1 or 2) preceding the presentation of the target stimulus in a simple visual detection task facilitated detection of target appearing in the left hemifield, while exposure to large numbers (8 or 9) facilitated target detection in the right hemifield (see also Stoianov et al, 2008).…”
