In example embodiments, a method includes obtaining a first measurement of at least a first physiological parameter of a user from a time before presentation of an information item to the user. The information item may be, for example, a notification, an advertisement, or an emergency alert, among other possibilities. A second measurement of the first physiological parameter is obtained from a time after a beginning of the presentation of the information item to the user (e.g. during the presentation). Based at least on a comparison between the first and second measurements, a determination is made of whether the user has perceived the information item. The determination may also be based on a corruption coefficient indicating an amount by which an activity of the user is likely to interfere with the first physiological parameter.
