This paper reexamines the effects of background speech on counting. Previous studies have shown that background sound disrupts counting in comparison with silence, but the magnitude of disruption is no larger for spoken numbers compared with that for non-number speech (there is no effect of the meaning of background speech). The typical task used previously has been to count the number of sequentially presented visual events. We replicated the general finding in Experiment 1that there is no effect of the meaning of background speechin the context of the classic sequence counting task. In Experiment 2, the task was changed by having to-be-counted dots presented simultaneously and randomly across the visual field. Here, an effect attributable to the meaning of background speech emerged. Background speech that is similar in meaning to the focal task process contributes to the magnitude of disruption, but apparently only when spatial memory processes are a task prerequisite.
