In addition, functional near-infrared spectroscopy (fNIRs) will be conducted at each of these time points to assess tasks of working memory, response inhibition, and facial recognition. The investigators will be using the NIRScout which is a portable NIRS recording unit. NIRS technology uses specific wavelengths of light, introduced at the scalp, to enable the noninvasive measurement of changes in the relative ratios of deoxygenated hemoglobin (deoxy-Hb) and oxygenated hemoglobin (oxy-Hb) in the capillary beds during brain activity.
