Illuminating numerical cognition with fNIRS: a developmental study
Representing the world in abstraction, numbers are central to humans as they are constantly informing our judgments and decisions. Every day, we use numbers to symbol quantities, index objects, and apply all sorts of calculations to solve problems. The existing literature has long established the ability to mentally represent approximate numerosity as a core knowledge, an intuition that is supported by the Approximate Number System (Xu & Spelke, 2000). While past studies have identified some key behavioral and neural signatures of number processing (Odic & Starr, 2018), its neurocognitive development in children is yet to be fully elucidated. Therefore, to further illuminate human numerical cognition, we hypothesize that there is an age-related effect in neural activation during number processing. Secondly, we hypothesize that the behavioral effect of ratio dependency can be observed neurally. To test our hypothesis, functional near-infrared spectroscopy (fNIRS), an optical brain imaging device that is non-invasive, motion tolerant, and child friendly, will be used to measure the participants’ neural activity during number comparison tasks.

Thank you so much for supporting my project! This experience has truly been an inspiring journey for me. Working as a research assistant for years, I have always wanted to lead a project on my own. It is your donation that rendered my dream possible. Thanks again for supporting me and the Illuminating the Brain Consortium! In the future, we hope to start many more projects to better understand human minds through the help of fNIRS, a cutting-edge brain imaging device.
