Systems and methods for the measurement of physiological responses caused by cognitive load and stress, to calculate a probability of deception. The system comprises modules to determine changes in the dilation of the pupils, the frequency of blinking, the ocular trajectory of the pupils, changes in temperature of the face, respiratory rate, the position of the user's facial points, heart rate, skin conductivity, body movements, temperature of the arm, electroencephalographic signals; and modules to provide stimuli to the user, to record the user's conscious responses, to receive the physiological signals and to determine changes in the user's stress- and cognitive load- associated physiological variables in response to stimuli generated for the calculation of a probability of deception in conscious responses. |
