Experiments 3, 3a, and 4 were conducted to explore the temporal capacity of the phonological store. The results showed that, irrespective of presentation modality, the irrelevant speech effect persisted even when articulation was suppressed through a 10 seconds retention interval. These findings contradict Baddeley's assumption that phonological traces decay rapidly, in about 1.5 to 2 seconds, when rehearsal is prevented by articulatory suppression. Phonological codes can be maintained for at least 10 seconds without the help of subvocal rehearsal.
The comparison between the irrelevant speech effect for visually and auditorily presented items (experiments 1 to 4) led us, in the final two experiments, to investigate the possibility that the irrelevant speech effect on auditorily presented items is actually a suffix effect. In conclusion then, our findings of experiments 5 and 6 favour the view that the irrelevant speech effects with visual and auditory presentation do not reflect the same mechanism. Rather, the irrelevant speech effect with auditorily presented recall items might result from the same mechanisms as those involved in the suffix effect.
