Hung, W., Ng, K.T., & Huang, T.-R. (2018) RetrievalInduced Forgetting in Social Contexts: A MetaAnalysis. The 30th Association for Psychological Science (APS) Convention. San Francisco, USA.
“Within-individual Retrieval-induced Forgetting” (WI-RIF) refers to the phenomenon that an individual’s selective retrieval of items (Rp+) often causes more forgetting of categorically related and yet unrehearsed items (Rp-) than categorically unrelated and unrehearsed items (Nrp). WI-RIF has been also reported in social settings as “Socially-shared Retrieval-induced Forgetting” (SS-RIF). For example, when a group of people mention parts of their shared experience in conversations, both speakers and listeners suffer from forgetting of related and yet unmentioned memory.
We conducted meta-regression on 59 studies.
Overall results show the Practice Effect is negatively correlated to the Suppression Effect when the practice session were free conversations (blue dots).
Memorability Bias: The more memorable the material, the more likely it is to be mentioned in a conversation and to be subsequently remembered (Cue et al., 2007).
Therefore, we are interested to test Memorability Bias under both free conversation and non-free conversation practice sessions.
Our hypothesis is the large effect size of Socially-shared Retrieval-induced Frogetting under free-conversations and the negative correlation is due to the effect of Memorability Bias.
We further test this hypothesis by conducting experiments.
Conducting experiment on a young group of people aged between 20~35, and an older group aged above 60. The results as following aligned to the meta-analysis.
The figure below shows that the more memorable the item, the more likely it is to be recalled during practice, becoming a Rp+ items, whereas the less memorable items are less recalled during practice. Therefore, becomes Rp- items more often. So apart from the RIF effect, the Memorability Bias is having an affect on the large effect size.
