Why the study?
A database of electrodermal activity signals was needed to provide accurate and effective indicators derived from cognitive science using the Affect-tag solution.
Does the Affect-tag A1 band accurately measure affective and cognitive indicators in participants?
Does the Affect-tag A1 band accurately measure affective and cognitive indicators in participants?
The Affect-tag A1 band demonstrated an 89% accuracy score for combined affective and cognitive indicators based on electrodermal activity.
May support wearable EDA monitoring in research; leaves open clinical adoption pending prospective validation.
The Affect-tag solution measures physiological signals to deliver indicators derived from cognitive science. To provide the most accurate and effective results, a database of electrodermal activity (EDA) signals acquired using the Affect-tag A1 band was created. An experimental paradigm was designed to measure action-taking, autonomic regulation, cognitive load (CL), emotions, and stress, affects, and social stress. The Affect-tag emotional power (EP), emotional density (ED), and CL affective and cognitive indicators were refined based on the physiological responses of 48 participants during these tasks. Statistical significance was obtained for all indicators in tasks they were designed to measure, resulting in a total accuracy score of 89% for the combined indicators. Data obtained during this study will be further analyzed to define emotional and affective states.
