Abstract

"Prior research had indicated considerable variation among the strains of rats in shock avoidance in the absence of external warning stimulation. This variation was directly tested, using black and albino rats. The black strain was very significantly superior to the white in shock avoidance. The blacks improved with time; the whites showed a decrement. These results were discussed both in terms of possible causes, including the reliably greater activity level of the black Ss, and methodological significance." From Psyc Abstracts 36:01:1EK20S.
