The production effect is a robust memory phenomenon where words that are read aloud are more likely to be remembered that words read silently. To date, all investigation of if the production effect extends to non-words has used phonetically legal non-words that sound like words. In this study I presented participants (N=15, M=37.7 years) with alphanumeric-type non-words, new type of non-word that lacks semantic meaning and is unpronounceable, to investigate if the production effect extends to words that do not sound like words, in a within-subjects design, replicating the methodology of MacLeod et al. (2010). Analysis of Variance (ANOVA) and follow up paired samples t-tests revealed participants in my sample did not discriminate between alphanumeric-type non-word stimuli they had seen previously and new foils, and a statistically significant effect of production for words read aloud compared to words read silently was not observed. Alphanumeric-type non-word stimuli may lack distinctiveness, or increase task complexity, moderating the production effect. Future research of the production effect may benefit from further investigation of task complexity.
