1. A procedure for measuring perception, in particular for measuring the visual attention of an individual, whereby at least the first visual coordinates of a first point of vision ( 37 ), assigned to an initial visual field image—in particular those determined using an eye tracking system—are processed, and at least the second visual coordinates of a second point of vision ( 38 ), assigned to a second visual field image, are processed, with the second visual field image recorded after the first visual field image, characterised in that the second visual coordinates of the second point of vision ( 38 ) are examined with the first visual coordinates of the first point of vision ( 37 ) in a comparative device to check whether they fulfil at least one of the initial predetermined fixation criteria ( 25 ), and that the first and second points of vision ( 37 , 38 ), provided they fulfil the initial fixation criterion ( 25 ) are assigned to a first fixation ( 48 ) that can be assigned to ordered perception, and marked as such, and that, if they do not fulfil the initial fixation criterion ( 25 ), the first and second points of vision ( 37 , 38 ) are assigned to a first saccade, to be assigned to aleatoric perception, and marked as such.
