Studying how working memory works
Working memory (WM) plays a central role in our mental life. It is the ability to hold and manipulate information in our mind over brief intervals, like when we need to remember a phone number. The question is how the brain balances between internal storage and external sampling when the remembered information is no longer physically present. The EU-funded HOMEOSTASIS project hypothesises that WM maintains a perceptual homeostasis by dynamically trading the costs of accurate internal storage against external sampling of the external visual world. To test the hypothesis, the project will study WM in interaction with the physically present environment. Electroencephalographic decoding techniques will be used to decode the current content. Virtual reality technology will also be used to study WM in interaction with worlds of varying reliability and familiarity.
