Development of Spatial Number Representations and Numerical Abilities in ChildrenAbstract:Background: The existence of spatial representations of number magnitude (mental number line) has been convincingly demonstrated in adults by associations between ...
Extended abstractNeurocognitive Foundations of Typical and Atypical Number DevelopmentBackground: The acquisition of basic mathematical abilities represents an essential component of leading a successful and healthy life in modern societies. While the ...
Numeracy and Finger Gnosis in Primary School Children: Is there a Relationship?Abstract.Background: Children often automatically use their fingers to help them counting and calculating. The use of fingers allows solving math problems by counting, ...
Zusammenfassung. Es wird ein Überblick über die Entwicklung der Rechenfunktionen gegeben. Im Detail geht der Beitrag auf die Epidemiologie, Erklärungskonzepte zur Zahlenverarbeitung und zur Dyskalkulie ein. Des Weiteren werden verschiedene Modelle zur ...
Zusammenfassung. Im Rahmen einer Längsschnittstudie wurden die numerischen Fertigkeiten von 334 Vorschulkindern einer repräsentativen Stichprobe aus dem Kanton Zürich (Schweiz) untersucht. Auf der Grundlage neurowissenschaftlicher Theoriebildung wurde ...
Zusammenfassung. In der vorliegenden Studie wurde die Prävalenz von Rechenstörungen mit einem longitudinalen Design in einer deutsch-schweizer Stichprobe nach zwei Jahren Schulbesuch erhoben. Die Erfassung von numerischem Wissen erfolgte mittels ...
Neurocognitive correlates of dyscalculiaVarious potential determinants of dyscalculia on the cognitive as well as on the neural level are presented. Findings concerning approximate quantity representations, basic visual mechanisms for capturing ...
Abstract. In this paper, a parity judgment task and a number naming task were used to investigate cross-notational number priming. Primes and targets could be verbal (e.g., seven) or Arabic numbers (e.g., 7), and were always presented in a different ...
Abstract. It is thought that number magnitude is represented in an abstract and amodal way on a left-to-right oriented mental number line. Major evidence for this idea has been provided by the SNARC effect (Dehaene, Bossini, & Giraux, 1993): responses to ...
The ideomotor principle predicts that the anticipation of expected sensory consequences precedes and controls voluntary goal-directed movements. Recent studies have revealed that an ideomotor mechanism could also support the link between finger movements ...
Abstract. Many studies demonstrated interactions between number processing and either spatial codes (effects of spatial-numerical associations) or visual size-related codes (size-congruity effect). However, the interrelatedness of these ...
