Relation of the Aubert-Foerster phenomenon to manifest anxiety

The relation of the increase in distance to narrowing of the visual angle was investigated with 20 subjects in high and low anxiety states. Stimulu were introduced from the periphery, and readings were taken at the limits of sharp perception of figures. The investigation partially confirmed that increase in distance resulted in narrowing of the visual field for the group low in anxiety. However, the visual angles were greater for the group high in anxiety.
