from "Classical Studies memes for Hellenistic teens" on FB
Plato's Cave allegory, illustrated. the shadows on the cave wall are captioned "increasingly insane and extreme positions", the prisoners labeled "internet users", the figures holding the shadow's shapes labeled "algorithms", the fire labeled "random internet users expressing their idiosyncratic beliefs". the space above the cave is labeled "literally just outside" and the philosopher freed from the chains of the physical world labeled "guy who logs off"

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 seen goal gradient like effects emerge in cognitive effort tasks but how does attention to goal progress ?

a new study from our lab, by Sean Devine and others, uses eyetracking to answer this question

A growing body of evidence across psychology suggests that (cognitive) effort exertion increases in proximity to a goal state. For instance, previous work has shown that participants respond more quic...

Three new CDML publications to start off 2025!

First up: research on multidimensional control from @davideghez.bsky.social in @naturehumbehav.bsky.social! Across three behavioral experiments and with computational modeling, Davide shows that people adapt control in a distractor-specific fashion.

Gheza and Kool show that, in multidimensional environments, people allocate attention to individual distractors on the basis of their interference with the current task. They develop a neural model th...

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?
