• Speech perception
• speech production
• speech processing
• event-related potentials
• mismatch negativity

Previous studies showed that manipulating the speech production system influenced speech perception. This influence was mediated by task difficulty, listening conditions, and attention. In the present study we investigated the specificity of a somatosensory manipulation - a spoon over the tongue - in passive listening. We measured the mismatch negativity (MMN) while participants listened to vowels that differ in their articulation - the tongue height - and familiarity - native and unknown vowels. The same participants heard the vowels in a spoon and no-spoon block. The order of the blocks was counterbalanced across participants. Results showed no effect of the spoon. Instead, starting with the spoon enhanced the MMN amplitude. A second experiment showed the same MMN enhancement for starting with a somatosensory manipulation applied to a non-articulator - the hand. This result suggests that starting a study with a somatosensory manipulation raises attention to the task.
