Predictions for the current study

Hypothesized role for the cerebellum	Prediction: Visual presentation	Prediction: Auditory presentation
1) Articulatory rehearsal   e.g., Paulesu et al., 1993	(−) Reduced similarity effect	(+) Preserved similarity effect
2) Phonological short-term store	(−) Reduced similarity effect	(−) Reduced similarity effect
3) Interface between articulatory rehearsal and phonological short-term store   e.g., Desmond et al., 1997	(−) Reduced similarity effect	(+) Preserved similarity effect*

^*Assuming that the inferior cerebellum is not itself part of the phonological STS.
