Der Kompatibilitätseffekt in der Zahlenverarbeitung : eine ereigniskorrelierte EEG-Untersuchung
… 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 comparisons require different decisions reaction times and error rate will increase. This experimental effect is known as the …

Zwei Wege zur Paritätsentscheidung: eine fMRT-Studie zur Notations-/Modalitätsspezifität in der Zahlenverarbeitung
… representations. First, an abstract semantic magnitude representation is assumed to be connected bilaterally to the horizontal intraparietal sulcus. Second, verbal formats as well as multiplication and arithmetical fact retrieval are supposed to be represented in left hemispheric perisylvic …

Effects of demagnetizing factors on transient motion of ferrofluid in a uniform rotating magnetic field
… direction and field strength). The shapes and magnitudes of the velocity profiles measured by an ultrasound velocimeter system differed between containers, indicating that demagnetizing factors did affect flow. The complicated flows within the flattened spheres that affected both the shape and …

On the structure and neural correlates of the numerical magnitude representation and its influence in the assessment of verbal working memory
… In compatible number pairs unit and decade digit magnitude comparison lead to identical response tendencies (e.g. 89_74, 8 > 7 and 9 > 4). For incompatible number pairs this is not the case (e.g. 63_48, 6 > 4 but 3 < 8). Faster reaction times (RT) for compatible number pairs (compatibility effect) …

The role of multi-digit number processing in the development of numerical cognition
… of number words vs. Arabic numbers vs. magnitude) as well as between semantic processes like number comparison and asemantic processes like transcoding. Up to date, it has not been tested empirically whether these notions are also adequate to describe the acquisition of multi-digit …

Supporting children’s conceptual understanding of fractions with manipulatives and gesture
… children’s learning of fraction notation and magnitude estimation. Preliminary results suggest that three of the four conditions—a gesture-based lesson, a manipulatives and gesture-based lesson, as well as a pencil and paper-based control, but not the manipulative-based lesson—led to learning …

Emerging Design Methodology And Its Implementation Through Rns And Qca
… complexity involved in the conversion process, magnitude comparison, overflow detection, sign detection, parity detection, scaling and division. The advancements in very large scale integration technology and demand for parallelism computation have enabled researchers to consider RNS as an …

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). …

The morphology of the intraparietal sulcus in children prenatally exposed to alcohol in a sample of children from the Western Cape, South Africa and its potential relationship with number processing
… activation of the IPS in the performance of magnitude comparison tasks was strongly associated with PAE. The IPS is an extremely variable structure whose anatomy is often misunderstood, which emphasises the importance of anatomical knowledge for imaging studies. Future research will refine …
