In this study, we propose a scheme to investigate the relationship between cognitive tasks and heart beat rate. Accordingly, a video focused on the face was recorded during a working memory experiment. Heart rate was noninvasively estimated from the camera recording. Subsequently, its spectral features were examined. These values were compared with heart rate dynamics obtained from a standard ECG. As a result of the comparison, we observed that the data from the video were compatible with the common heart rhythm, except its spectrum did not have 1/f character.
