Claims of a 'new' stuttering treatment using time-out from speaking are exaggerated: a brief review of the literature and commentary on Hewat et al. (2006)Jack E James
National University of Ireland, Galway, Ireland

Department of Psychology, National University of Ireland, Galway, Ireland
Psychopharmacology (Berl) 182:1-8. 2005..The central question is whether superior performance and mood after caffeine represent net benefits, or whether differences between caffeine and control conditions are due to reversal of adverse withdrawal effects...
Dietary caffeine, performance and mood: enhancing and restorative effects after controlling for withdrawal reversalJack E James
National University of Ireland, Galway, Ireland
Neuropsychobiology 52:1-10. 2005..Caffeine had no significant net enhancing effects for either performance or mood when participants were rested, and produced no net restorative effects when performance and mood were degraded by sleep restriction...
