Abstract

BackgroundTraditional self-reported measures in health science education often overlook the physiological processes underlying cognitive and emotional responses. PurposeThis review aims to analyze the frequency, sensitivity, and utility of physiological markers in understanding cognitive and emotional dynamics in learning environments. MethodsA systematic PubMed search identified 156 records, with 13 studies meeting inclusion criteria. Markers analyzed included heart rate (HR), heart rate variability (HRV), cortisol, alpha-amylase, testosterone, s-IgA, blood pressure, oxygen saturation, and respiratory rate. Main FindingsHR and HRV were sensitive to educational stressors. Cortisol and alpha-amylase showed mixed results, while testosterone and s-IgA showed limited utility in directly assessing stress responses. No consistent link was found between any marker and immediate learning success. ConclusionPhysiological markers in learning environments can offer valuable insights into emotional and cognitive dynamics but should not be misconstrued as direct indicators of learning outcomes.
