The representation of numbers in space : a journey along the mental number line
The present thesis deals with the mental representation of numbers in space. Generally it is assumed that numbers are mentally represented on a mental number line along which they ordered in a continuous and analogical manner. Dehaene, Bossini and Giraux (1993) found that the mental number line is …

A synthesis of cognitive science research on the mental number line, and its relation to the pedagogical use of number lines in the teaching of elementary arithmetic in the Foundation Phase of schooling
… frame our experiences as it relates to using the number line in school mathematics. This study is a synthesis of the research findings in cognitive science and mathematics education to elucidate the mechanisms that underpin the connection between the mental number line in humans and its relation …

Neuronal and cognitive correlates of attentional and automatic semantic number processing
Number magnitude is assumed to be encoded in an analog visuo-spatial frame, which resembles a left-to-right oriented and logarithmically compressed mental number line. Some authors have suggested that also the semantic representation of multidigit numbers can be described by their location on the …

Räumliche Orientierung auf dem mentalen Zahlenstrahl : eine kombinierte Reaktionszeit- und fMRT-Studie
Semantic number magnitude is represented in an analogue visual-spacial system in the shape of a left-to-right oriented, logarithmically compressed mental number line; the most important evidence is the SNARC (Spatial Numerical Association of Response Codes)-effect (Dehaene, Bossini & Giraux, 1993). …

How spatial is spatial language? Investigating the relationship between spatial cognition and abstract language processing
… these effects was replicated; the presence of a mental number line. From each of the language tasks, a spatial grounding sensitivity score was calculated based on the difference in reaction times between incongruent and congruent trials. These sensitivity scores were then correlated to …

Interactions between numbers and space : neurobehavioural evidence from children and adults
Mental number representations were examined in this thesis by asking participants to compare either numerical or spatial distances of visually presented number triplets (e.g. 57 64 92), a so-called "numerical landmark test". Varying numerical and spatial distances independently resulted in neutral, …

Der Kompatibilitätseffekt in der Zahlenverarbeitung : eine ereigniskorrelierte EEG-Untersuchung
… are asked to compare a pair of two-digit Arabic numbers with regard to numerical size, previous studies have shown them to respond faster and at a lower error rate if both the magnitude comparisons of the decade digits and the unit digits lead to the same response. In contrast, if the two …

Componenti spaziali della rappresentazione cognitiva della grandezza del numero
The humans process the numbers in a similar way to animals. There are countless studies in which similar performance between animals and humans (adults and/or children) are reported. Three models have been developed to explain the cognitive mechanisms underlying the number processing. The …

Raising Teacher Sensitivity to Key Numeracy Competencies in the Early Years
… professional knowledge about the sequence of number development and the predictors of mathematical difficulties was provided to teachers of five to eight-year-old students. Tools were provided which focussed on linear tracks (board games) as an external model of number magnitude. The study …

On the structure and neural correlates of the numerical magnitude representation and its influence in the assessment of verbal working memory
… on the nature and neural correlates of the mental representation of two-digit numbers. Second, it investigates whether numbers are well suited to serve as stimulus material in the assessment of verbal working memory (vWM). Dehaene, Dupoux and Mehler (1990) claimed that two-digit numbers are …
