Der Kompatibilitätseffekt in der Zahlenverarbeitung : eine ereigniskorrelierte EEG-Untersuchung
When participants 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 …

Notations-, Aufgaben- und Strategiespezifität in der Zahlenverarbeitung : eine fMRT-Studie
Introduction: The anatomo-functional model of Dehaene and Cohen (1995) assumes a number processing network of different number representations. Most importantly, the inferior parietal lobule contains an abstract semantic magnitude representation. The model does not consider notation-, task- or …

Zwei Wege zur Paritätsentscheidung: eine fMRT-Studie zur Notations-/Modalitätsspezifität in der Zahlenverarbeitung
Introduction: According to Dehaene and Cohen (1995) as well as Dehaene et al. (2003), numbers are processed depending on notation, modality and task. Three codes are claimed to build a network of functional and anatomical number representations. First, an abstract semantic magnitude representation …

Mental number representation as assessed by the number bisection task : a combined reaction time and fMRI study
In this combined reaction time (RT) and functional Magnetic Resonance Imaging (fMRI) study, the number bisection task as a verification paradigm was used to examine whether this task only relies on a quantitative representation of number magnitude as postulated by Dehaene and Cohen (1997) or …

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 …

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, …

Eine Untersuchung zur Entwicklung der mentalen Repräsentation von Zahlen bei Kindern der zweiten Schulklasse anhand der Navon-Aufgabe
The following paper deals with number crunching as well as parity concept concerning second grader. Based on the current data of former studies, there is obvious inconsistency whether children are using irrelevant properties in order to process a target number and furthermore how the properties of …

Keine Zahl ohne Zeichen : der Einfluss der medialen Eigenschaften der DGS-Zahlzeichen auf deren mentale Verarbeitung
This dissertation addresses the question whether media-specific features of sign systems have an influence on the mental processing of these signs or not. This research question is investigated with the mental number processing of German deaf signers. The number system in the German Sign Language …
