Abstract
Threshold for grating detection have been measured in six human observers for different orientations (vertical, horizontal, oblique 45° and oblique 135° Gratings of fifteen different spatial frequencies were presented monocularly to the observers through a circular window. The area of the window was different under two experimental conditions (A=3.14°2 and B=0.785°2). In all cases, the sensitivity was higher for the vertical orientation than for the other ones. Moreover, the sensitivity was lower for all the orientations when the B window was used, in this case, the sensitivity for the oblique orientations was higher than the horizontal one.
