- Located within the Department of Psychology at Western University


- Part of the Brain and Mind Institute


- Directed by Dr. Daniel Ansari, consisting of graduate students and post-doctoral fellows from the fields of Psychology, Neuroscience, and Education


- We aim to better understand what predicts success and failures in early math learning


- Focus of our research is to gain a better understanding of how children develop numerical and mathematical competencies

Tests are provided in PDF format

with detailed assembly instructions

in both text and video formats

A 2-4 minute test composed of two parts:
1. Symbolic (i.e. numerical digits)
2. Non-Symbolic (i.e. arrays of dots)


- Developed by Drs. Nadia Nosworthy & Daniel Ansari in the Numerical Cognition Laboratory at Western University


- Measures a child's ability to understand numerical magnitude (quantity)


- Correlations between performance on the Numeracy Screener and arithmetic skills have been demonstrated and published in scientific literature


- These findings show that performance on the Numeracy Screener can explain individual differences in children's arithmetic skills
