Glucose enhancement of a facial recognition task in young adults

Glucose enhancement of human memory: A comprehensive research review of the glucose memory facilitation effect

“…Previous findings support a role for glucose in facilitating attention (Benton, 1990;Meikle et al, 2004;Reay et al, 2006), face recognition (Metzger, 2000), semantic memory , verbal fluency (Donohoe and Benton, 1999a), visuospatial functioning (Scholey and Fowles, 2002), visuospatial long-term memory (Sünram-Lea et al, 2001, 2002a, 2002b and working memory (Hall et al, 1989;Kennedy and Scholey, 2000;Meikle et al, 2004;Reay et al, 2006;Scholey et al, 2001;Sünram-Lea et al, 2002b;see Table 2). Further, in addition to verbal episodic recall, oral glucose ingestion has been reported to enhance recognition memory for a supraspan word list in healthy young adults Sünram-Lea et al, 2001, 2002a, 2002b.…”

Glucose effects on long-term memory performance: duration and domain specificity

“…Metzger and Flint (2003) found that following administration of 50 g of glucose, participants recognised more target faces than subjects who consumed the placebo drink (saccharin). Metzger (2000) investigated the effect of glucose consumption on a facial recognition task in young adults, using 50 g glucose and found no effects of face recognition. However, he did observe that following a glucose drink, participants made significantly fewer errors.…”

“…To date, only few studies have examined the effects of glucose administration on our ability to recognise faces. Metzger (2000) investigated the effect of glucose consumption on a face recognition task. Using a population of healthy young adults, glucose (50 g) or saccharin administration took place 15 min prior to the face recognition task.…”

Glucose administration prior to a divided attention task improves tracking performance but not word recognition: evidence against differential memory enhancement?

“…Foster et al 1998;Sünram-Lea et al 2001;2002a, b, 2008Messier 2004). On the other hand, glucose has also been shown to benefit non-mnemonic performance, including reaction times , rapid visual information processing Donohoe and Benton 1999;Reay et al 2006), the Stroop paradigm , Porteus maze and block design tasks (Donohoe and Benton 1999), the BrownPeterson working memory task (Martin and Benton 1999), driving simulator performance (Keul et al 1982), kinaesthetic memory (Scholey and Fowles 2002), face recognition (Metzer 2000) and serial subtraction mental arithmetic (Kennedy and Scholey 2000;Scholey et al 2001;Sünram-Lea et al 2002a;Reay et al 2006). There are also studies which have failed to find any direct effect of glucose on tasks assessing secondary memory (Azari 1991;Scholey et al 2001;Ford et al 2002;Scholey and Kennedy 2004).…”
