Psychophysics of Numerical Representation A Unified Approach to Single- and Multi-Digit Magnitude Estimation
When estimating the value of Arabic numerals like ‘‘3,’’ ‘‘33,’’ and ‘‘333,’’ is each symbol treated holistically and associated with a different mental magnitude along a common scale (Dehaene, 1989), or is there unique scaling for units, decades, hundreds, and so on (McCloskey, 1992)? In this opinion piece, we argue that the evidence is more consistent with the holistic, single-scaling account...
متن کاملEnhancing performance in numerical magnitude processing and mental arithmetic using transcranial Direct Current Stimulation (tDCS)
The ability to accurately process numerical magnitudes and solve mental arithmetic is of highest importance for schooling and professional career. Although impairments in these domains in disorders such as developmental dyscalculia (DD) are highly detrimental, remediation is still sparse. In recent years, transcranial brain stimulation methods such as transcranial Direct Current Stimulation (tD...
متن کاملOn the limits of language influences on numerical cognition – no inversion effects in three-digit number magnitude processing in adults
The inversion of number words influences numerical cognition even in seemingly non-verbal tasks, such as Arabic number comparison. However, it is an open question whether inversion of decades and units also influences number processing beyond the two-digit number range. The current study addresses this question by investigating compatibility effects in both German- (a language with inverted) an...
متن کاملMulti-Representation of Symbolic and Nonsymbolic Numerical Magnitude in Chinese Number Processing
Numerical information can be conveyed by either symbolic or nonsymbolic representation. Some symbolic numerals can also be identified as nonsymbolic quantities defined by the number of lines (e.g., I, II, III in Roman and -, =, ≡ in Japanese Kanji and Chinese). Here we report that such multi-representation of magnitude can facilitate the processing of these numerals under certain circumstances....
متن کاملLanguage influences on numerical development—Inversion effects on multi-digit number processing
In early numerical development, children have to become familiar with the Arabic number system and its place-value structure. The present review summarizes and discusses evidence for language influences on the acquisition of the highly transparent structuring principles of digital-Arabic digits by means of its moderation through the transparency of the respective language's number word system. ...
