Hmmm, this suggests that the evidence for shortcut use as an indicator of applying a cognitive map seem to be weak even in humans. Maybe a cautionary note here for all the cognitive map studies where the map structure and metrics (e.g., hexagonal symmetry) are much more vague

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Online Now: The Reward Positivity signals a goal prediction error
dlvr.it
The Reward Positivity signals a goal prediction error
The Reward Positivity (RewP) is an electroencephalogram (EEG) feature that emerges following performance feedback and is commonly understood to index both positive and negative reward-prediction error (RPE+ and RPE−, respectively) signals. In contrast to this dominant perspective, we argue that the RewP is an independent EEG feature that selectively responds to positive RPE and is superimposed on a common background signal. We further propose that the RewP signals a goal prediction error: it is elicited by abstract signals instead of by hedonic 'rewards'. This goal prediction error appears to be produced by a critic-like architecture that is associated with the actor–critic framework in reinforcement learning. This perspective emphasizes the role of the RewP in goal attainment and cognitive control as opposed to being a simple indicator of reward receipt.

I very much like how this perspective considers the different goals and techniques for defining brain organization. Recognizing that cytoarchitecture, connectivity, macroscale gradients, and even manifolds place different constraints on function helps reconcile the different interpretations.
