In this ongoing project, we extend MB3 investigation on the ability to learn and to apply rules by adding a non-invasive brain imaging technique to the experimental design: near-infrared spectroscopy (NIRS). With this addition, we may be able to identify neural correlates that inform whether and to what extent rules’ processing and learning are abstract, rule-based, and/or language specific. We may also be able to explore the time course of learning, thereby adjudicating between statistical mechanisms requiring extended time for sampling and faster symbolic mechanisms.

NIRS is a relatively new imaging technique. Variation across instruments, analysis pipelines, and laboratories is wide and standardization is currently lacking. Using NIRS in this large-scale collaborative project will provide us with the unique opportunity to discuss and solve some of these issues in a global network of experts in developmental research and brain imaging.
