Magnitude processing in non-symbolic stimuli
Dot arrays are often used to study basic numerical skills across cultures, species and development. Researchers investigate the ability of subjects to discriminate between dot arrays, as a function of the ratio or distance between their numerosities. Such studies have contributed significantly to the number sense theory (i.e., that humans are born with the ability to process numerosities, and s...
متن کاملThe influence of math anxiety on symbolic and non-symbolic magnitude processing
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 as being the foundation for later math abilities, underlies math anxiety. However, these studies examined this hypothesis by investigating ANS acuity using a symbolic number compar...
متن کاملProcessing fractions and proportions: An fMRI study
Number cognition is important both for the society and for the individual. The disorder of number cognition (developmental dyscalculia) can havemajor impact on individual life quality. Several children and adults experience problemswith one aspect of ‘arithmetic syntax’, the representation of place value structure. Here we provide the first cognitive neuroscience investigation of place value re...
متن کاملCommon and segregated neural pathways for the processing of symbolic and nonsymbolic numerical magnitude: An fMRI study
Numbers are everywhere in modern life. Looking out a window, one might see both symbolic numbers, like the numerals on a thermometer, and nonsymbolic quantities, such as the number of chickadees at a bird feeder. Although differences between symbolic and nonsymbolic numbers appear very salient, most research on numerical cognition has focused on similarities rather than differences between nume...
متن کاملImproving Preschoolers’ Arithmetic through Number Magnitude Training: The Impact of Non-Symbolic and Symbolic Training
The numerical cognition literature offers two views to explain numerical and arithmetical development. The unique-representation view considers the approximate number system (ANS) to represent the magnitude of both symbolic and non-symbolic numbers and to be the basis of numerical learning. In contrast, the dual-representation view suggests that symbolic and non-symbolic skills rely on differen...
