The children were tested individually, seated at the table opposite the researcher. After introducing herself to the child the researcher said: “You are here to play some memory games. Please don’t be nervous but try the best you can to remember what I ask you to.” Analysis revealed that the children in the aroma room received significantly higher scores than the non-scented room. The test to recall words demonstrated the greatest different in scores. Dr Moss said: “Why and how rosemary has this effect is still up for debate. It could be that aromas affect electrical activity in the brain or that pharmacologically active compounds can be absorbed when adults are exposed. “We do know that poor working memory is related to poor academic performance and these findings offers a possible cost effective and simple intervention to improve academic performance in children. The time is ripe for large-scale trials of aroma application in education settings.”
