Cognitive training offers the potential for individualised learning, prevention of cognitive decline, and rehabilitation. However, key research challenges include ecological validity (training design), transfer learning long-term effects. Given that neuromodulation affect neuroplasticity, their combination could promote greater, synergistic We investigated whether combining transcranial direct current stimulation (tDCS) with further enhance performance compared to alone, within a short...
Number line estimation (i.e., indicating the position of a given number on physical line) is standard assessment children's spatial representation magnitude. Importantly, there an ongoing debate question in how far bounded task version with start and endpoint (e.g., 0 100) might induce specific strategies thus may not allow for unbiased inferences underlying representation. Recently, new unbounded was suggested only point unit fixed distance from to 1). In adults this provided less biased...
Abstract In recent theoretical considerations as well in neuroimaging findings the left angular gyrus (AG) has been associated with retrieval of arithmetic facts. This interpretation was corroborated by higher AG activity when processing trained compared untrained multiplication problems. However, so far neural correlates versus problems were only after training. We employed an established learning paradigm (i.e., extensive training problems) but measured brain activation before and afte to...
The attentional spatial-numerical association of response codes (Att-SNARC) effect (Fischer, Castel, Dodd, & Pratt, 2003)—the finding that participants are quicker to detect left-side targets when the preceded by small numbers and right-side they large numbers—has been used as evidence for embodied number representations support strong claims about link between space (e.g., a mental line). We attempted replicate Experiment 2 Fischer et al. collecting data from 1,105 at 17 labs. Across...
Deficits in basic numerical abilities have been investigated repeatedly as potential risk factors of math anxiety. Previous research suggested that also a deficient approximate number system (ANS), which is discussed being the foundation for later abilities, underlies However, these studies examined this hypothesis by investigating ANS acuity using symbolic comparison task. Recent evidence questions view can be assessed To investigate whether there an association between anxiety and acuity,...
There is evidence for a systematic association of numbers and space. A prominent finding supporting this notion the spatial-numerical response codes (SNARC) effect describing relatively faster responses to smaller using left-hand key larger right-hand key. However, assumption SNARC reflecting associations was challenged recently. working memory account proposed suggesting that not per se but their position in memorized sequence associated with Yet, there also first ordinal may be mutually...
Recent research indicates that processing proportion magnitude is associated with activation in the intraparietal sulcus. Thus, brain areas of numbers (i.e., absolute magnitude) were activated during symbolic fractions as well non-symbolic proportions. Here, we investigated systematically cognitive (e.g., and decimals) proportions dot patterns pie charts) a two-stage procedure. First, relative magnitude-related activations processing. Second, evaluated whether share common neural...
"Open" is not just a fancy synonym for transparent and accountable. The in Open Government, Data, Information, Innovation stands the changing relation between citizens authorities. Many no longer accept passive stance representative democracy held them. They take an active approach setting up better means of collaboration by ICTs. demand gain access to their historically grown collective knowledge stored government data. Not on local level, they actively shape political agenda. Government be...
Transcranial direct current stimulation (tDCS) is an innovative method to explore the causal structure-function relationship of brain areas. We investigated specificity bilateral bi-cephalic tDCS with two active electrodes same polarity (e.g., cathodal on both hemispheres) applied intraparietal cortices bilaterally using a combined between- and within-task approach. Regarding between-task specificity, we observed that affected numerical (mental addition) but not control task (colour word...
The operational momentum effect (OM) indicates an association of mental addition with a rightward spatial bias, whereas subtraction is associated leftward bias. To evaluate the assumed attentional origin OM effect, we evaluated not only participants’ relative estimation error in task requiring them to locate and results on given number line but also their eye-fixation behaviour. Furthermore, investigate situatedness spatial–numerical associations, orientation (left-to-right vs. right-to...
Decimal fractions comply with the base-10 notational system of natural Arabic numbers. Nevertheless, recent research suggested that decimal may be represented differently than numbers because two number processing effects (i.e., semantic interference and compatibility effects) differed in their size between In present study, we examined whether these differences indeed indicate are from Therefore, provided an alternative explanation for congruity effect, namely a string length effect....
Neurocognitive studies of arithmetic learning in adults have revealed decreasing brain activation the fronto-parietal network, along with increasing specific cortical and subcortical areas during learning. Both changes are associated a shift from procedural to retrieval strategies for problem-solving. Here we address critical, open question whether similar neurocognitive also evident children. In this study, 20 typically developing children were trained solve simple complex multiplication...
Zusammenfassung. Ein zunehmend komplexes Gesundheitssystem geht mit erhöhten Anforderungen an die Fähigkeit, sich darin zurechtzufinden, einher. So sehen Leistungsempfänger einer Fülle zum Teil widersprüchlichen gesundheitsbezogenen Informationen konfrontiert, es adäquat zu nutzen gilt. Hierfür müssen sie über eine Reihe von Fähigkeiten und Fertigkeiten verfügen, in der Literatur seit einigen Jahren unter dem Begriff health literacy bzw. Gesundheitskompetenz subsumiert werden. Allerdings...
Children's estimation patterns in bounded number line (NLE) reveal marked developmental changes. Three different theoretical accounts were proposed to explain these changes: a log-to-linear shift account, proportion-judgment account and two-linear considering familiarity with numbers or the understanding of place-value structure Arabic system. However, only first two are considered prominently ongoing scientific debate. Therefore, we present reanalysis NLE data Austrian first-graders...
