Herbal extracts and memory enhancement : Response to Scholey et al.

• Reply by the current author to the comments made by Scholey et al. (see record 2005-04969-023) on the original article (see record 2004-13858-010). The letter by Scholey et al. contains several accounts of criticism. The principal claim that they make is that, although negative findings of cognition-enhancing effects have been found in several studies, this is not enough evidence to conclude that these products do not improve cognitive performance. The authors emphasize that the methods used in these studies need careful examination and they identify a number of criteria that, preferably, should be met for these studies to be "adequately powered". The problem is (and this is also discussed by Scholey et al.) that even if these criteria are met, there are still negative findings.
