Disentangling age and schooling effects on inhibitory control development: An fNIRS investigation (2021)
Journal Article
McKay, C., Wijeakumar, S., Rafetseder, E., & Shing, Y. L. (2022). Disentangling age and schooling effects on inhibitory control development: An fNIRS investigation. Developmental Science, 25(5), Article e13205. https://doi.org/10.1111/desc.13205

Children show marked improvements in executive functioning (EF) between 4 and 7years of age. In many societies, this time period coincides with the start of formal school education, in which children are required to follow rules in a structured envir...

Frontotemporal activation differs between perception of simulated cochlear implant speech and speech in background noise: An image-based fNIRS study (2021)
Journal Article
Defenderfer, J., Forbes, S., Wijeakumar, S., Hedrick, M., Plyler, P., & Buss, A. T. (2021). Frontotemporal activation differs between perception of simulated cochlear implant speech and speech in background noise: An image-based fNIRS study. NeuroImage, 240, 1-15. https://doi.org/10.1016/j.neuroimage.2021.118385

In this study we used functional near-infrared spectroscopy (fNIRS) to investigate neural responses in normal-hearing adults as a function of speech recognition accuracy, intelligibility of the speech stimulus, and the manner in which speech is disto...

Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation (2021)
Journal Article
Jackson, E. S., Wijeakumar, S., Beal, D. S., Brown, B., Zebrowski, P. M., & Spencer, J. P. (2021). Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation. Journal of Clinical Neuroscience, 91, 32-42. https://doi.org/10.1016/j.jocn.2021.06.018

Few studies have investigated the neural mechanisms underlying speech production in children who stutter (CWS), despite the critical importance of understanding these mechanisms closer to the time of stuttering onset. The relative contributions of sp... Read More about Speech planning and execution in children who stutter: Preliminary findings from a fNIRS investigation.

Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy (2021)
Journal Article
Forbes, S. H., Wijeakumar, S., Eggebrecht, A. T., Magnotta, V. A., & Spencer, J. P. (2021). Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy. Neurophotonics, 8(2), Article 025010. https://doi.org/10.1117/1.nph.8.2.025010

Significance: Image reconstruction of fNIRS data is a useful technique for transforming channel-based fNIRS into a volumetric representation and managing spatial variance based on optode location. We present an innovative integrated pipeline for imag... Read More about Processing pipeline for image reconstructed fNIRS analysis using both MRI templates and individual anatomy.

Home assessment of visual working memory in pre‐schoolers reveals associations between behaviour, brain activation and parent reports of life stress (2021)
Journal Article
McKay, C., Shing, Y. L., Rafetseder, E., & Wijeakumar, S. (2021). Home assessment of visual working memory in pre‐schoolers reveals associations between behaviour, brain activation and parent reports of life stress. Developmental Science, 24(4), Article e13094. https://doi.org/10.1111/desc.13094

Visual working memory (VWM) is reliably predictive of fluid intelligence and academic achievements. The objective of the current study was to investigate individual differences in pre-schoolers’ VWM processing by examining the association between beh...
