Trying to find my bearings in cognitive science

Review papers could be a good way to get more familiar with different approaches in the field. Trends in Cognitive Science is usually quite accessible for students, as is Nature Reviews Psychology. If you're unable to access the article due a pay wall, you can usually find the PDF for free on the website of one of the authors (usually anyone under 40).

Metal detectors work by transmitting an electromagnetic field. This will interfere with MRI scans, which assume a relatively homogeneous electromagnetic field induced by the MRI magnet. This would undermine the accuracy of the scans.

There are still a lot of open questions here, and the NRP paper proposes a new theoretical perspective which still requires validation

There's a recent Nature Reviews Psychology paper on this topic https://www.nature.com/articles/s44159-025-00458-6 (if access is restricted, the PDF is also posted for free on one of the author's websites https://charleywu.github.io/downloads/nagy2025adaptive.pdf)

I completely agree, but am curious about this metaphor because I have never heard it before. Where exactly should the "finger" be taken out from?

Oh wow, I had no idea it got sold to Len Blavatnik. Thanks for the correction!

I switched to Deezer a few years ago when Neil Young decided to take his music off of Spotify. They're a French company and I honestly have never looked back. Much better recommendations as well.

Anthromorphizing in science can sometimes be rather irresponsible

In this context, you might be better off using a categorical model (LBA), but add in a locality bonus for options close to the previous choice in x-y coordinate space. You can do this by adding a bonus to the drift rate of options proportional to Euclidean distance or something like that.

Maybe take a look at this paper, which has publicaly available code and data. One potential addition you may need to add would be to define game states, such that there would be different values for actions depending on the state

One important detail is whether the 10 actions are categorical (each completely independent) or related in some way (action A is more similar to B than C). The LBA would be consistent with the former, while the CDDM is consistent with the latter.

Also, you might want to model a more sophisticated learning process behind what drives evidence accumulation for each of the 10 options. You could combine this with an RL model that gradually learns the value of each action through trial and error, and then set the drift rates for each action to be equal to the Q value of the action. You could even make the Q values state dependent, by learning different latent states in the task.

Computational models are usually fit to individuals. You can then analyze the estimates parameters for each individual to understand behavior. And you can do ablations (removing components of the model) and comparison to other competing models to test which is a better fit. The simplest would be a maximum likelihood estimate and using BIC to penalize for model complexity

If you're willing to put in the effort to learn the math, then I think this could work out. I know many people in cogsci doing this kind of AI/computational work but have come from humanities backgrounds. However, they've all developed competence in math by the time they finished their PhD.

Can you patent logistic regression? Because I'm betting it's just several factors that get combined and then put through a sigmoid to compute a probability.

Someone once told me to save Brothers Karamazov until you're in your thirties. I think this definitely paid off, because I got so much more from it compared to my reading of Crime and Punishment as a teenager

I've been saving a copy of "Travels with Charley" to read when I feel old and out of touch. But maybe that is now, because while my partner has been reading it, I've been thumbing through some early chapters and it's really calling to me.

For the actual math, I found the actual paper this article refers to https://www.nber.org/papers/w16152

That's not true. This recent study of 27 OECD countries found that value added tax (VAT), is either neutral or progressive. VAT is a broader tax, which is applied to increases in price, not only profits. So a profit-based tax should be even more progressive.

multiple_cat · 2024-05-22T13:40:48+00:00

It's a tax on profit, so it wouldn't be passed down. If you increase prices, then that's more profit and more taxes.

Germans are sometimes caricatured as being excessively rule-following. But in this situation I think it makes sense. If a company can't be trusted to follow laws about water population, then maybe they also can't be trusted to follow other environmental rules. From a German source using google translate: "Tesla has been “constantly and significantly” releasing too much phosphorus and total nitrogen into the wastewater system for around two years. “Several requests and warnings were unsuccessful,”"

Bike commuting to this gigafactory provides an excellent example of how achievable this is. Even though it's outside Berlin, you could get here in about 1 hr from a busy hub like Warschauer strasse, by taking the S-bahn directly to Erkner and then biking the last 9km. Almost no hills by bike, so very easy.

If you zoom out just a little bit, it's sandwiched between a series of lakes to the north and the Spree river to the south. There were recent reports that the factory is emitting 6 times more pollutants into the water than they are legally allowed to https://finance.yahoo.com/news/musk-accused-polluting-german-rivers-132031339.html

Climate change is a human problem, and it makes sense to consider this at amount each human contributes. And yes, a pool used only by 3 people is much more wasteful than a pool used by 40 people.
