Directly assessing the relationship between irrelevant speech and articulatory suppression

Q J Exp Psychol A. 2003 Nov;56(8):1269-78; discussion 1301-6. doi: 10.1080/02724980244000756.


Larsen and Baddeley (2003) examine whether the disruption caused by articulatory suppression on immediate memory tasks is similar to or different from the disruption caused by irrelevant speech. Based on experiments in which they test whether the phonological similarity effect is present or absent, they conclude that articulatory suppression and irrelevant speech are different. We assessed whether articulatory suppression and irrelevant speech are similar or different by correlating the disruption each causes. A significant correlation obtained, indicating a relation between the two. These apparently different conclusions can be readily resolved by adopting the view that articulatory suppression, irrelevant speech, and many other factors vary in the degree to which they are likely to cause subjects to abandon reliance on phonological/acoustic cues in particular tasks.
