Attenuation of retroactive inhibition by a single electroconvulsive shock

Abstract

A retroactively interfering reversal habit. a left or right turn in a single-unit water maze. was learned by 28 rats. The in terpolated habit was immediately Jiillowed in 14 of the animals by a single elee troshoek eon vulsion. R eliable "interferenee with retroaetive interferenee" was found: shoek animals were superior in demonstrating retention of originallearning. This [inding is diseussed with re[erenee to major behavioral theories o[ ECS and interpreted as being more nearly supportive of amnesie. as opposed to fear-induetion or eompeting-response. meehanisms.
