Abstract

The Zubek effect (the CFF of the non-occluded eye in monocularly-deprived subjects shows an initial decrease followed by an increase) was investigated. The initial depression effect was confirmed, but, though greater in the deprived subjects, it was present in the control groups as well. This effect was found to be primarily due to circadian fluctuations in the CFF, the CFF increasing from 9:00AM to 12s00Noon and then declining. No evidence was found to support the earlier claim of an enhancement effect. The results are discussed in terms of hormonal influences on sensory functioning.
