The impact of caregiver inhibitory control on infant visual working memory (2024)
Journal Article
Davidson, C., Theyer, A., Amaireh, G., & Wijeakumar, S. (2024). The impact of caregiver inhibitory control on infant visual working memory. Infant Behavior and Development, 74, Article 101921. https://doi.org/10.1016/j.infbeh.2023.101921

Visual working memory (VWM) emerges in the first year of life and has far-reaching implications for academic and later life outcomes. Given that caregivers play a significant role in shaping cognitive function in children, it is important to understa...

Stunting in infancy is associated with atypical activation of working memory and attention networks (2023)
Journal Article
Wijeakumar, S., Forbes, S. H., Magnotta, V. A., Deoni, S., Jackson, K., Singh, V. P., …Spencer, J. P. (2023). Stunting in infancy is associated with atypical activation of working memory and attention networks. Nature Human Behaviour, 7(12), 2199–2211. https://doi.org/10.1038/s41562-023-01725-3

AbstractStunting is associated with poor long-term cognitive, academic and economic outcomes, yet the mechanisms through which stunting impacts cognition in early development remain unknown. In a first-ever neuroimaging study conducted on infants fro... Read More about Stunting in infancy is associated with atypical activation of working memory and attention networks.

Home enrichment is associated with visual working memory function in preschoolers (2023)
Journal Article
Davidson, C., Caes, L., Shing, Y. L., McKay, C., Rafetseder, E., & Wijeakumar, S. (2024). Home enrichment is associated with visual working memory function in preschoolers. Mind, Brain, and Education, 18(1), 72-84. https://doi.org/10.1111/mbe.12383

Home enrichment plays an important role in shaping children's development. In the current study, we inquired whether home enrichment was associated with pre-schoolers' visual working memory (VWM) function, a critical cognitive system necessary for ma...

The first year in formal schooling improves working memory and academic abilities (2023)
Journal Article
Davidson, C., Shing, Y. L., McKay, C., Rafetseder, E., & Wijeakumar, S. (2023). The first year in formal schooling improves working memory and academic abilities. Developmental Cognitive Neuroscience, 60, Article 101205. https://doi.org/10.1016/j.dcn.2023.101205

Neurocognition and academic abilities during the period of 4 and 7 years of age are impacted by both the transition from kindergarten to primary school and age-related developmental processes. Here, we used a school cut-off design to tease apart the... Read More about The first year in formal schooling improves working memory and academic abilities.

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.
