This time it's personal: the memory benefit of hearing oneself

The production effect is the memory advantage of saying words aloud over simply reading them silently. It has been hypothesised that this advantage stems from production featuring distinctive information that stands out at study relative to reading silently. MacLeod (2011) (I said, you said: The production effect gets personal. Psychonomic Bulletin & Review, 18, 1197-1202. doi: 10.3758/s13423-011-0168-8 ) found superior memory for reading aloud oneself vs. hearing another person read aloud, which suggests that motor information (speaking), self-referential information (i.e., "I said it"), or both contribute to the production effect. In the present experiment, we dissociated the influence on memory of these two components by including a study condition in which participants heard themselves read words aloud (recorded earlier) - a first for production effect research - along with the more typical study conditions of reading aloud, hearing someone else speak, and reading silently. There was a gradient of memory across these four conditions, with hearing oneself lying between speaking and hearing someone else speak. These results imply that oral production is beneficial because it entails two distinctive components: a motor (speech) act and a unique, self-referential auditory input.
