James Swanson, one of the earliest researcher who promoted amphetamines in the 90’, in this piece by @nytimes.com on a.d.h.d. and stimulants. “there is no long-term effect. The only long-term effect that I know of has been the suppression of growth.“

However, these results are contingent on whether the task features can be decoded. Activity-silent, or 'bursts' of proactive processes sprinkled in the ITI and not time-locked to the stimulus, may not appear with our method. Therefore, the proactive unicorn is still galloping even in our task.
I'll plug this in: we run the Multi task with EEG and, adapting Kikumoto's decoding+RSA method, we can see a change in distractors' coding compatible with the distractor-specific adaptation reported in our recent NHB. This 'looks' like reactive, given it shows up 500ms post-stimulus.

We've got an excellent line-up in both philosophy and neuroscience for our first conference! Submit your abstracts by Feb 1 and join us in St. Louis in early May!
😎 SPAN2025 Keynotes, invited symposia speakers, and sponsored symposia just dropped! Take a look at who will be at SPAN2025 and then submit your abstract so you can be there too!

More invited speakers will be announced soon. Visit our website for all the details: philandneuro.com
It's out!

Great conversations with @ndosenbach.bsky.social while preparing this Nature News & Views on the new Kang et al. Ready to have the same with everyone here. Thoughts? What other practice should be investigated to help BWAS reproducibility?

Overall, this suggests that attentional gains for multiple sources of information can be adapted in parallel.

This opens the questions of how ‘multidimensional’ conflict is represented in the brain.

Check out the discussion of our preprint for some speculation.
With a neural network model, we show that you need multiple, distractor-specific conflict monitors.
In short, humans can simultaneously adapt attention towards multiple sources, based on their individual ‘compatibility’ history.

(Lasagne never helped writing a great epitaph. Life stories did)
We observe within-dimension adaptation, but absence of cross-dimension adaptation.

Put simpler, participants adapted attention to a given dimension based selectively on the congruency history of that dimension with the cued task.
a.k.a. ‘spaghetti plot’. It would be lame if it wasn’t how we actually refer to this effect.
Control adaptation in the MULTI produces parametric congruency sequence effects.

You are robust to congruency effects the more you have been previously exposed to incongruence (flatter, lighter lines).

(Check out @hritz.bsky.social’s new paper for a related, convergent, finding!)
The congruency of non-cued dimensions spans from 0 (all incongruent) to 3 (all congruent). This leads to parametric effects on responses to the cued dimension.
Also, interference comes from everywhere: Any non-cued dimension interfere with any cued task (as in the best families).
In our new MULTI paradigm, two stimuli differ across 4 dimensions. Your need to find the instructed feature for a given cued dimension (aka ‘write the epitaph’).
The three other dimensions can either facilitate or interfere (i.e., your sister and your aunt).
Families can be large.

Could you compose your cousin's epitaph while your sister shares his life stories, and also suppress your aunt’s push for more lasagne?
