NIR spectroscopy measurements of cognitive load elicited by GKT and target categorization

摘要: Near infrared (NIR) is a portable, safe, affordable, non-invasive and negligibly intrusive functional optical imaging modality, which enables the measurement of metabolic changes associated with cognitive activity. In this paper, we present experimental procedures data analysis near (fNIR) measurements acquired from forehead during tasks. The collected subjects engaged in two standardized tasks, namely, 'target categorization' 'guilty knowledge test' (GKT). case target categorization, aim to study blood oxygenation volume level while participants are experiencing decrements vigilance, increased lapses attention, slowing. We measured 25 minutes-long responses 11 performing categorization. Data results revealed that missed targets higher than captured targets. deceptive truthful were 16 GKT analyzed using statistical analysis. our showed 'lie' task 'truth' task.
