Error Correcting Dynamics in Working Memory
Updated: May 29
We show there are two forces acting on memories. First, memories diffuse over time (presumably due to noise in neural activity). Second, memories drift over time. This drift causes your memories to morph from their original value (e.g. 'pink') to another value that occurs in the world more often (e.g. 'red'). Although this drift seems bad at first, we found it actually improves the accuracy of working memory because it counteracts the effect of diffusion!
