Abstract
The effects of chlorpromazine, scopolamine, and pentobarbital
on the visual short-term memory trace were studied using the Sperling
design. Analysis of variance showed a significant difference among
the drug treatments (p<.05). The mean numbers of correct responses for
scopolamine, pentobarbital, and placebo, among which there was no significant
difference, were pooled and found to differ significantly from
the chlorpromazine mean (p<.OI). It was concluded that chlorpromazine
improved performance either by filtering post-stimulus "noise" or by
delaying the encoding process for the visual STH trace, thereby making
the information available longer.
