Eye Fixation and the Contents of Recall and Images as a Function of Heart Rate

Abstract
Our aim was to illustrate an eye-fixation photographic method of studying cognition both with and without awareness. We focused upon (a) the time of inspection of a part of the visual field in relation to (b) the recall of that part of the stimulus and (c) the relationships of (a) and (b) as a function of heart rate. Recall was defined in two ways: direct and unintentional, i.e., recovery in the content of waking images of picture content which had not appeared in direct recall. Eighteen Ss were overloaded with information by a 6-sec. exposure of a card containing four complex pictures. Waking images were followed by recall. Recovery via images was significantly related to inspection time of the picture quadrant; direct recall was not. The more the person was accelerated in his response via heart rate or fixation rate, the greater his recovery in images.
