A technique to allow the study of prolonged after‐images as perfectly stabilized retinal images is described. A simple model to account for the variability of unitary or fragmentary disappearance of stabilized images is proposed and tested. Results suggest the presence of recognition units mediating the perception of straight lines which vary in size from approximately 30 to 90 min arc in the human fovea and perifovea. These units appear to be arrayed independently of orientation, and may be primarily represented in the cortex. A reappraisal of the methodology and theoretical significance of stabilization studies is attempted.
