Encoding and recall of parsed stories in hypnosis.
To define the relationship between aspects of memory concerning encoding and recall of short texts and hypnosis, standardized stories were narrated to 12 subjects, both during ordinary state of consciousness and after hypnotic induction by means of the Stanford Hypnotic Susceptibility Scale (Form C). The narrative material used as a stimulus was based on several stories taken from popular oral tradition, previously analyzed according to the classic criteria proposed by Rumelhart in 1975 and Mandler and Johnson in 1977. The subjects' memory performance during both experimental conditions was tape-recorded and compared with the analysis of the original stories (Terminal Nodes) as well as with the higher linguistic structures of the scheme (Basic Nodes), according to Rumelhart's typology. During hypnosis, the subjects recalled significantly fewer narrative elements at both levels of analysis (Terminal Nodes and Basic Nodes). We conclude that hypnosis does not enhance recent memory.
