Effects of development and enculturation on number representation in the brain
- D. Ansari
- Psychology, Medicine
- Nature Reviews Neuroscience
- 1 April 2008
A striking way in which humans differ from non-human primates is in their ability to represent numerical quantity using abstract symbols and to use these 'mental tools' to perform skills such as… Expand
Mapping numerical magnitudes onto symbols: the numerical distance effect and individual differences in children's mathematics achievement.
- I. Holloway, D. Ansari
- Mathematics, Medicine
- Journal of experimental child psychology
- 1 May 2009
Although it is often assumed that abilities that reflect basic numerical understanding, such as numerical comparison, are related to children's mathematical abilities, this relationship has not been… Expand

Neural correlates of symbolic number processing in children and adults
- D. Ansari, Nicolas Garcia, Elizabeth K. Lucas, Kathleen M. Hamon, B. Dhital
- Psychology, Medicine
- Neuroreport

- 1 May 2012
The numerical ratio effect (NRE) and the Weber fraction (w) are common metrics of the precision of the approximate numbers sense (ANS), a cognitive mechanism suggested to play a role in the… Expand
Age-related Changes in the Activation of the Intraparietal Sulcus during Nonsymbolic Magnitude Processing: An Event-related Functional Magnetic Resonance Imaging Study
Numerical magnitude processing is an essential everyday skill. Functional brain imaging studies with human adults have repeatedly revealed that bilateral regions of the intraparietal sulcus are… Expand
Bridges over troubled waters: education and cognitive neuroscience
- D. Ansari, Donna Coch
- Psychology, Medicine
- Trends in Cognitive Sciences
- 1 April 2006
Recently there has been growing interest in and debate about the relation between cognitive neuroscience and education. Our goal is to advance the debate beyond both recitation of potentially… Expand
