“…Another possible interpretation of the effect of temporal distance on IPS activity draws on the idea that the IPS may play a general role in ordinal processing. Distance effects in IPS activity have indeed been observed in many different domains, including numerical and alphabetical processing (Fias, Lammertyn, Caessens, & Orban, 2007;Pinel, Dehaene, Riviere, & LeBihan, 2001), and STM for order (Attout, Fias, Salmon, & Majerus, 2014;Marshuetz, Reuter-Lorenz, Smith, Jonides, & Noll, 2006). These and related findings have led to the view that the IPS (especially the anterior IPS) supports domain general ordinal processes that allow coding for serial order in various task domains (Attout et al, 2014).…”

Abstract■ Although growing evidence has shown that remembering the past and imagining the future recruit a common core network of frontal-parietal-temporal regions, the extent to which these regions contribute to the temporal dimension of autobiographical thought remains unclear. In this fMRI study, we focused on the event-sequencing aspect of time and examined whether ordering past and future events involve common neural substrates. Participants had to determine which of two past (or future) events occurred (or would occur) before the other, and these order judgments were compared with a task requiring to think about the content of the same past or future events. For both past and future events, we found that the left posterior hippocampus was more activated when establishing the order of events, whereas the anterior hippocampus was more activated when representing their content. Aside from the hippocampus, most of the brain regions that were activated when thinking about temporal order (notably the intraparietal sulcus, dorsolateral pFC, dorsal anterior cingulate, and visual cortex) lied outside the core network and may reflect the involvement of controlled processes and visuospatial imagery to locate events in time. Collectively, these findings suggest (a) that the same processing operations are engaged for ordering past events and planned future events in time, (b) that anterior and posterior portions of the hippocampus are involved in processing different aspects of autobiographical thought, and (c) that temporal order is not necessarily an intrinsic property of memory or future thought but instead requires additional, controlled processes. ■

“…On the other hand, Holloway and Ansari (2008) demonstrated that the DE in numerical and non-numerical comparisons is similar, supporting the idea of the DE in comparison reflecting a decisional mechanism. Also neuroimaging studies showed that comparison of number and letter comparison activate very similar parieto-frontal networks in humans, nourishing the idea of common decision mechanisms (Fias, Lammertyn, Caessens, & Orban, 2007). A crucial test would be to investigate the relationship between nonnumerical decision processes and mathematics achievement and dyscalculia.…”

“…The ability of humans to process ordinal relationships is not restricted to numerical information, but rather extends to other non-numerical dimensions such as the letters of the alphabet (e.g., Fias, Lammertyn, Caessens, & Orban, 2007;Franklin et al, 2009;Fulbright, Manson, Skudlarski, Lacadie, & Gore, 2003;Gevers, Reynvoet, & Fias, 2003. As such it is a feasible assumption that a relationship between arithmetic and other sequentially organized symbols, such as letters of the alphabet, may exist.…”

Processing the order of symbolic numbers: A reliable and unique predictor of arithmetic fluency

A small but growing body of evidence suggests a link between individual differences in processing the order of numerical symbols (e.g., deciding whether a set of digits is arranged in ascending/descending order or not) and arithmetic achievement. However, the reliability of behavioral correlates measuring symbolic and non-symbolic numerical order processing and their relationship to arithmetic abilities remain poorly understood. The present study aims to fill this knowledge gap by examining the behavioral correlates of numerical and nonnumerical order processing and their unique associations with arithmetic fluency at two different time points within the same sample of individuals. Thirty-two right-handed adults performed three order judgment tasks consisting of symbolic numbers (i.e., digits), non-symbolic numbers (i.e., dots), and letters of the alphabet. Specifically, participants had to judge as accurately and as quickly as possible whether stimuli were ordered correctly (in ascending/descending order, e.g., 2-3-4;Results of this study demonstrate that numerical order judgments are reliable measurements (i.e., high test-retest reliability), and that the observed relationship between symbolic number processing and arithmetic fluency accounts for a unique and reliable portion of variance over and above the non-symbolic number and the letter conditions. The differential association of symbolic and non-symbolic numbers with arithmetic support the view that processing the order of symbolic and non-symbolic numbers engages different cognitive mechanisms, and that the ability to process ordinal relationships of symbolic numbers is a reliable and unique predictor of arithmetic fluency.Keywords: numerical and non-numerical order, arithmetic abilities, reverse distance effect, canonical distance effect, reliability, ordinality processing, symbolic numbers, non-symbolic numbers, arithmetic fluency Journal of Numerical Cognition, 2017, Vol. 3(2), 288-308, doi:10.5964/jnc.v3i2.55 Received: 2016-05-31.
