Abstract : Thirty-two subjects performed a perceptual line judgement task at two levels of difficulty during the retention interval of a letter memory task, which also varied in difficulty. One half of the subjects were instructed to stop rehearsal of the memory letters prior to making the line judgement, while the other subjects were given no instructions to stop rehearsal. Line judgement reaction times, memory reaction times and percent error on the memory task were analysed for single and dual task conditions. The results indicated that an increase in memory task difficulty produced an increase in line judgement reaction time, but only for the group given no instructions to stop rehearsal of the memory letters, and only with the easier line judgement task. Neither group displayed an effect of memory load on line judgement reaction time in the more difficult condition. This was attributed to a ceiling effect. Performance on the memory task was equivalent for the two groups.
