Sweet, sweet review by the awesome @anne-urai.bsky.social on the beautiful mess that is behaviour.
Also, best abstract ending I've seen in a long time:
'There is probably no such thing as stable behavior.'

Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors Nature Communications - Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors

Who doesn't like a good model of the brain? Yet, from simple regression to neural nets, some limitations keep popping up (e.g., overfitting) @mjwolff.bsky.social & I saw some cool but puzzling data, ran a quick analysis & found one such limitation: model mimicry. Now in #naturecommunications &🧵below

A direct neural signature of serial dependence in working memory Magnetoencephalographic recordings revealed a direct neural signature of serial dependence, that is, an attractive bias of current toward previous representations, which emerged at late, post-encoding...

Our paper on the neural basis of serial dependence is finally published!

Key messages:
- 80% chance that at least one of the next five years will exceed 2024 as the warmest on record
- 86% chance that at least one of next five years will be more than 1.5°C above the 1850-1900 average

This was a fun project based on our work together with students doing their semester projects in the cognitive psychology course at UiB. It is also the first replication project I publish, but probably not the last. 7/7

Re-focusing visual working memory during expected and unexpected memory tests Memory tests evoke a second stage of internal attentional deployment following both expected and unexpected memory tests, extending attentional re-orienting to working memory.

Explore the contrasts across Europe, from the dry and often record-warm conditions in the east to warm but wet conditions in the west. #ESOTC2024 is a joint effort between #CopernicusClimate and @wmo-global.bsky.social, together with over 100 scientists. bit.ly/3G9MdEX

Very happy that this primer on software engineering principles for psychology and cognitive neuroscience is now out! This was a great joint project between my group (lead by postdoc Yunyan Duan) and @martinhebart.bsky.social's group (led by @rothj.bsky.social).

I am so happy—this is the first 1st author paper I have written, since the cancer diagnosis of my late wife seven years ago.

Are short-term memories just noisier versions of what we perceive? Are they fundamentally different? We (Chaipat Chunharas, @mjwolff.bsky.social, @meikehettwer.bsky.social and myself) delved into this in a paper out now in #elife: elifesciences.org/reviewed-pre.... For a quick summary, a 🧵 below:
