Past literature suggests that an early indicator of reading ability is how precisely individual words are represented in the brain. That is, individuals who read fluently would have distinct representations of each word in their brain. Previously, using electroencephalography (EEG), we found that more differentiated brain responses to individual words were associated with stronger reading ability.

## Overview of the Current Study
To build on previous research examining the relationships between brain activity and reading ability, the present study is a 2-year longitudinal study. Children from grades 2 and 3 are recruited and participation lasts until they are in Grades 4 and 5. We’ll conduct one neuroimaging session to examine their neural activity patterns in response to individual words and multiple reading assessments over the two years. With neuroimaging tools, and behavioural measures of reading ability, we can then investigate if more differentiated brain responses, to different words, are related to better reading skill.

We’ll conduct one neuroimaging session to examine their neural activity patterns in response to individual words and multiple reading assessments over the two years. To look at children's brain activity, we will be using functional near-infrared spectroscopy (fNIRS). fNIRS is a child-friendly brain imaging technique that shines near-infrared light on the scalp to record changes in the amount of oxygen in the brain’s blood (click [here](neuroimaging/#functional-near-infrared-spectroscopy-fnirs) for more information). With fNIRS, and behavioural measures of reading ability, we can then investigate if more differentiated brain responses, to different words, are related to better reading skill.

## Objectives
The goal of this study is to investigate the relationship between reading skills and children's brain responses to words, so that we can better understand how individual differences in brain activity relate to children’s future reading abilities.
