Ah, great point - thanks! I hadn’t really thought of serial dependence or those contextual biases in this context. Will check those out and see how they map onto what we’re finding.

... delay-related changes in bias, I’m not convinced they actually increase (or decrease) - even though my initial intuition was that they should. We're finalizing that work now and can share it with you in the next couple of weeks - would be great to hear if you think we're missing something.

Thanks for sharing these. My understanding of Gi-Yeul's work is that these biases (also in colour) are most likely perceptual, and the analysis of the data in Fig. 3 supports that. To be fair, I had W-S’s law in mind when asking you about data, because after a non-trivial amount of looking for...

Now out in JEP:G! We (@fridaprintzlau.bsky.social & @keisukefukuda.bsky.social ) resolve inconsistent attentional protection in WM by addressing discrepancies in cueing. Upshot: Attention changes how perception biases memory, but *not* how memory biases perception!

Really interesting! Just skimming the paper - it looks like they focus on changes in decision-consistent biases with delay, which is new to me. Is that also the case for estimation biases? If so, could you point me to work showing changes in estimation biases with delay (besides Panichello et al.)?

Our key finding is that a resource allocation mechanism based solely on the history of accumulated rewards is sufficient to explain differences in estimation performance based on intrinsic as well as external rewards.

To explain these findings, we built a neural resource model, constrained by a reinforcement learning rule! It describes how intrinsic and extrinsic rewards jointly shape the value assigned to different stimuli, which biases how processing resources are allocated in future encounters.
