This double-blind, placebo-controlled study examined the influence of appetitive state on glucose enhancement of memory. Participants rated their mood, hunger and thirst, then consumed a 25 g glucose drink or a matched placebo 20 min prior to a verbal memory task. There was a double dissociation when the effects of thirst ratings and drink on subsequent memory performance were considered. Those who were initially less thirsty recalled significantly more words following glucose than placebo; those who were more thirsty recalled significantly fewer words after glucose than placebo. Glucose enhancement of memory may therefore critically depend on participants' initial thirst. Crown
