Depth perception in the dark-reared rat as a function of time in the dark
- 154 Downloads
Dark-reared hooded rats were tested for depth perception on the visual cliff. Ss were given an equal density condition to equate retinal angle presented during testing. Ss were kept in the dark from birth and tested after 40–170 days without visual stimulation. Dark-reared Ss 90 days of age, and perhaps to 125 days of age, discriminated depth. No group kept in the dark 140 days of longer discriminated depth.
