Earlier this year, Sam Clarke, Liz Brannon, and I published a paper taking a critical look at the phenomenon of *number adaptation*. A reply by Burr, Anobile, and Arrighi is forthcoming in Cognition. You can see their reply here: papers.ssrn.com/sol3/papers.cf…

This is wild! Apparently a strong predictor of whether a community is a "Blue Zone" with unusually many 100-yr-olds is whether it also has unusually *few* 90-yr-olds…one of many pieces of evidence that it's all just erroneous birthdates & pension fraud 😮 theconversation.com/the-data-on-ex…

A few postdocs asked me to read over their job applications. Here’s a few bits of advice: 🧵 /10 1. If any advice doesn’t ring true for you, discard it (including this!) 2. People on the search committee are keen to welcome a colleague, they aren’t looking to take you down

All kinds of exciting plans are afoot here Johns Hopkins University, and this is part of it! Three positions in Psychological & Brain Sciences — one each in cognitive psychology, cognitive neuroscience, & behavioral neuroscience. These are very broad searches (in both rank and area). Apply!

This new paper spearheaded by Matt Self shows the link between border-ownership tuning in area V4 of the visual cortex and figure-ground signals in area V1, by an analysis of the pattern of noise correlations between neurons in these two cortical areas. nature.com/articles/s4146…

This is the system prompt for Apple Intelligence. Turns out Apple's prompt engineers are as clueless about how LLM work as all the others.
