Hypnotic time distortion and free-recall learning — an attempted replication

Hypnotic time distortion and free-recall learning — an attempted replication Krauss, Katzell and Krauss (1974) have presented evidence suggesting that hypnosis can be used to facilitate free-recall learning. Specifically, they report that ‘hypnotised’ individuals, given special time-distortion instructions, can recall as much in three minutes as ‘waking’ control subjects can in ten minutes. The present study was an attempt to replicate and extend this main finding of Krauss et al. The results of the present study failed to replicate Krauss et al.'s finding; in fact, the hypnotised subjects did rather worse than ‘waking’ control groups; also no relationship was found between recall scores and ‘depths’ of hypnosis. Marked discrepancies were noticed between the scores of the waking control groups used in the present study, and those used by Krauss et al. It was concluded that any facilitatory effect of hypnotic time distortion on free-recall learning still awaits a definitive demonstration. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Psychological Research Springer Journals

Abstract

Krauss, Katzell and Krauss (1974) have presented evidence suggesting that hypnosis can be used to facilitate free-recall learning. Specifically, they report that ‘hypnotised’ individuals, given special time-distortion instructions, can recall as much in three minutes as ‘waking’ control subjects can in ten minutes. The present study was an attempt to replicate and extend this main finding of Krauss et al. The results of the present study failed to replicate Krauss et al.'s finding; in fact, the hypnotised subjects did rather worse than ‘waking’ control groups; also no relationship was found between recall scores and ‘depths’ of hypnosis. Marked discrepancies were noticed between the scores of the waking control groups used in the present study, and those used by Krauss et al. It was concluded that any facilitatory effect of hypnotic time distortion on free-recall learning still awaits a definitive demonstration.
