Abstract

A NEW test of immediate memory was recently suggested by Buschke1. N — I items drawn from an ensemble of N are presented, and the task is to name the missing item. An experiment is described in which this technique, the ‘missing scan method’, was used to evaluate the effects of sub-anaesthetic doses of nitrous oxide on immediate memory. The results seem to cast light on underlying processes. It is suggested that two forms of storage may be distinguished—that used depending on the presentation-rate of items—and that one form is especially susceptible to drug effects.
