Visual Enumeration and Estimation: Brain mechanisms, Attentional demands and Number representations.
… this thesis explored the roles of attention and number awareness in visual enumeration and estimation through a variety of methods. First, a distinction was made between different attentional modes underlying estimation and enumeration in an in-depth single case study of a patient with …

From Magnitudes to Math: Developmental Precursors of Quantitative Reasoning
… animals. Although humans typically think about number symbolically, we also possess nonverbal representations of quantity that are present at birth and shared with many other animal species. These primitive numerical representations are thought to arise from an evolutionarily ancient system …

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 …

Kindergarten children's estimates of numerosity
… than the reference point of 10 on the referent-number estimation task. Adding a second reference point of 20 made the order-of-magnitude estimation task more difficult, especially for set sizes between the two reference points. Open-ended estimation, which offered no reference point, was …

Mental number representation as assessed by the number bisection task : a combined reaction time and fMRI study
… 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 perhaps also on other number representations and …

Notations-, Aufgaben- und Strategiespezifität in der Zahlenverarbeitung : eine fMRT-Studie
… 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 strategy-specific differences. …

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, …

The development of a digital logic concept inventory
Instructors in electrical and computer engineering and in computer science have developed innovative methods to teach digital logic circuits. These methods attempt to increase student learning, satisfaction, and retention. Although there are readily accessible and accepted means for measuring …

Zwei Wege zur Paritätsentscheidung: eine fMRT-Studie zur Notations-/Modalitätsspezifität in der Zahlenverarbeitung
… 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 is assumed to be connected …

Enhancing Early Number Learning: Effects of an 8- Week Abacus Training Intervention on Subitising, Counting, and Motivation
… and policymakers to prioritise counting and number learning, many children continue to struggle to meet expected standards in this area globally (e.g., Department for Education, 2017; Steffe, 2017). This study addressed the current research gap by exploring how structure interventions, such …
