Abstract
Experiments by Craik and Tulving (1975) suggest recall is enhanced using deeper levels of processing by giving meaning to words, semantic processing, combined with requiring more attention resources at encoding. Based on this an experiment was designed to test if non-matching olfactory triggers presented at encoding improved recall. This was done by presenting words paired with matching, non-matching, or no smell conditions, then measuring the number of words recalled by 20 female and 13 male participants in a controlled experiment. Data was analyzed using a one way independent ANOVA and Post Hoc tests. Results, F (2.33) =4.638, p = 0.018, showed that recall was improved when matching olfactory triggers were presented however no significant difference was found between the non-matching and control conditions. This suggests the more successful recall, due to the matching condition, may be linked only to deeper semantic processing of words and triggers presented.
