Abstract
Four groups of rats were preadapted, respectively, to no-shock,.004 mA,.008 mA, and.02 mA, before being conditioned in a jump box to.03 mA shock preceded by a bell CS. Both the.004-mA and the,008-mA groups required significantly fewer trials (p <.01) to criterion than the other two groups. The results were related to those of studies using subliminal anchor stimuli with human Ss and were interpreted in an adaptation-level framework.
