Animal Learning and Behavior Sense


The capacity of the bushbaby, Galago senegalensis, to discriminate intermittent visual stimuli was investigated. Critical flicker frequency (CFF) was estimated at four flash intensities by a modified method of limits. The maximum behavioral CFF obtained for this nocturnal prosimian was 27.4/sec. Results were discussed in terms of the retinal structure of galago and were compared to human scotopic CFF.
