New perspective paper from our lab: “The hippocampus as a generative model” out now !! royalsocietypublishing.org/rstb/article... The traditional view of the hippocampus is that it creates a cognitive map. Here we extend this view to conceptualise the hippocampus as a “generative model”.
The hippocampus as a generative model
Abstract. A generative model can be defined as a model of the latent causes of sensory input that can be used to generate new data samples. By examining em

Finally out in Psychological Review (psycnet.apa.org/doi/10.1037/...), our update to Signal Detection Theory. We show that contrary to the prevailing Gaussian assumption, evidence distributions in recognition memory are likely minimum extreme Gumbel!
Honey, we fixed Signal Detection Theory (SDT)! In this preprint, Constantin Meyer-Grant, David Kellen, Sam Harding, and I critically evaluate the (unequal-variance) Gaussian SDT model in recognition memory and pursue the Gumbel-min model as a principled alternative: doi.org/10.31234/osf... 🧵

📣 New preprint 📣 "Neural Dynamics of Belief and Value Computations Guiding Strategic Social Decisions" We use EEG and computational modeling (combining learning + DDM) to explain participants' choices, RT, and neural signals in a strategic game. www.biorxiv.org/content/10.6...
Neural Dynamics of Belief and Value Computations Guiding Strategic Social Decisions
Successful strategic behavior must be grounded in beliefs about the opponent and her intentions. While many potential models have been proposed to explain choices in such situations, the neural mechanisms that govern learning and choice in complex strategic contexts remain poorly understood. Here, we use a computational model that combines dynamic learning and choice mechanisms to explain both choices and response times of human participants engaged in a competitive strategic task. Using electroencephalography (EEG), we identify temporally structured stages of neural processing that support an evolving value-based decision process, corresponding to first- and second-order belief updates and evidence accumulation related to the comparison of action values. Gamma-band phase coupling between central and parietal EEG signals varied with individual winning rate, suggesting that strategic behavior involves coordinated information transfer across spatially remote areas. Together, our data characterize the temporally evolving neural dynamics of belief and valuation processes that underlie strategic choice and provide neural validation for assumptions embedded in computational models of this behavior. ### Competing Interest Statement The authors have declared no competing interest.
