And to be clear, my post is not a critique of y’all’s study. Great to have more evidence of the issues with unproctored online studies!

suggested edit: when you collect data online *in unproctored sessions*, are the results from humans or AI?

Every time you experience something new, your brain faces a decision: Should it update an existing memory or create a new one?

In our new paper in @sfnjournals.bsky.social #JNeurosci, we isolate that exact decision, moment-by-moment during learning 🧡

Jayme Lawson from Sinners hit the nail on the head and said how I felt with the whole BAFTAs situation.

Across my interviews with developers, AND across my conversations with people who were not as of several months ago developers and now are (???), this motivation effect is clear. I am baffled that psychology is not more interested in this: the expectation of what's possible is changing for people

Elon Musk posted about race almost every day in January Many social media posts by Tesla CEO on his platform are indiscernible from those of white supremacists, say experts

β€œThe richest man in the world posted about how the white race was under threat, made allusions to race science or promoted anti-immigrant conspiracy content on 26 out of 31 days in January”

How many versions of the Iowa Gambling Task (IGT) exist? And how much does this affect research using the IGT? More than you might think. 🧡

I'm trying to decide whether to start having lab meetings (as well as 1-1 supervisions) this year. We're a small group (5 students).

Keen to hear what works for you all?!

Possible formats:
- roundtable brief progress reports
- longer project update talks
- journal club
- skill share sessions
-...?

MTurk and other recruitment platforms could still be great for getting a larger, more diverse sample. But if you want quality responses, you probably need to monitor the participants (and pay appropriately).

This is nitpicky and not really directed at you but the issue is these are unsupervised! What about recruiting participants from these platforms and using zoom or some other platform to monitor participants? I did that. data seemed pretty much fine.

Blocked by @mehr.nz for quote-tweeting this about the screencapped post.

Unreal how thin-skinned people are, when they are willing to publicly hurl stones at others. Honestly, truly pathetic behaviour.

the research and consenting process seems fine to me. Your reply seems over the top and posting the student’s name, lab, and institution seems extreme.

This is a model for what actual masculinity should be. Men don’t need to spend more time in caves beating their chests with other men; they need to take their daughters to a meaningful thing and talk to them about it. Relatedly I think the biggest cure for toxic masculinity is platonic women friends

Letter to the Guardian.
The protection of badgers has a long pedigree (Report, 29 August). Arthur Gore, known as "Boofy", the eighth Earl of Arran, was a fanatical defender of them. He was also a tireless campaigner for the rights of homosexuals. In 1967 he managed to push through a law in the Lords that decriminalised homosexuality but failed to pass a bill to outlaw the cruel hunting of badgers. When asked why he had not received enough support for his badger bill, he replied: "Not many badgers in the House of Lords." Tony Lywood Keswick, Cumbria

Found when sorting an old drive. I still, very occasionally, say 'not many badgers in the House of Lords' and this is why:

OpenWMData A collection of publicly available working memory datasets

Do you have an open working memory dataset and want it to be findable and reused? You can now add it to the Open WM Data Hub: williamngiam.github.io/OpenWMData! The collection of datasets tagged with useful metadata is steadily growing thanks to a small team of volunteers!

🚨 SynthNet is out 🚨
Researchers propose new constructs and measures faster than anyone can track. We (@anniria.bsky.social @ruben.the100.ci) built a search engine to check what already exists and help identify redundancies; indexing 74,000 scales from ~31,500 instruments in APA PsycTests. 🧡1/3

It's sad that AI conference reviewers use "incremental" as reason to reject a paper -- e.g., "the contribution of this paper is incremental; reject". Where do they think most progress in science comes from, and what eventually fuels big discoveries?

new paper by Sean Westwood:

With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

My red line has always been lowering health costs for Americans. Donald Trump and Republicans don’t want an agreement that meets that bar. I’m a no.

I’m voting no on the continuing resolution that would double healthcare premiums for 20 million Americans, kick 15 million people off Medicaid & allow 50,000 Americans to die unnecessarily every year.

All to give $1 trillion in tax breaks for billionaires.

My reviewing style has changed over time. Rather than litigate every little thing, and pushing my own ideas, I focus only on 2 things:
(1) Are the claims interesting/important?
(2) Does the evidence support the claims?

Most of my reviews these days are short and focused.
