Don't miss this one ⤵️. A wide-ranging and provocative conversation covering disparate issues like: How do we balance accuracy versus breadth as scientists? Why should we read a book written in 1897? When is a paw a hand? And should scientists cede the term "dopamine" to the pop-psychologists?

Exactly the type of thing I love about the furry elephant.

On jargon - is it useful? Is it necessary and useful for scientists to say "mnemonic" to refer to "memory" and "affect" to talk about "emotion"? In other words, given that everyone understand emotion and mood and no one really understands what "affect" is until you are really deep into things, why is the term affect useful and important at all? And should we reserve it for deep dives (as opposed to public facing websites and such)? And does anyone call themselves an "emotion researcher?" or a "mood researcher?" @PessoaBrain @[email protected]

Sorry if I'm not including everyone here.

I think we need more jargon in neuroscience (mind/brain).

Couple of examples. Examine the mess that is the debate about "consciousness" because (in part) so many senses are mixed, including "sentience", "awareness", etc.

Or the fact that we use basically folk psychological terms all the time. So even if qualify what I mean by attention* in one of my papers, using a term that is used in a dozen ways will surely lead to confusion.

Our mind/brain field is highly technical, but the language surprisingly accessible to most people. That's a problem not because we want to be "distinguished professors" but because of the complete terminological confusion we inhabit!

I couldn't read all the discussion, so apologies if this was already discussed and debunked... 🙂

Some counter-examples from fields where terms do have strict definitions yet use words which also have a wide range of everyday meanings (i.e. are not "jargon" per se): mass, power, gravity, element, compound, volume...

I think it's useful to reflect on how *unproblematic* the technical use of these terms is as opposed to, say, "consciousness" or "attention." The problem then reduces to an absence of strict definitions more than to polysemy.

CJ Stevens - Metaphysiology Sep 6, 2023

@PessoaBrain @NicoleCRust @brembs @DrYohanJohn In other words, we shouldn't avoid using certain terms in science on the basis that they already have common everyday meanings. We should consider avoiding certain terms in science on the basis that they don't yet have a strict scientific definition conducive to rigorous delimitation of inquiry/investigation. I believe the nuance between these two reasons is worth bearing in mind.

I think physical concepts like mass etc aren't fraught with all the cultural baggage of psychological terms. Few people have strong opinions on what "volume" means, but many have some notion of what "emotion", "thinking", or "attention" mean.

The case of "representation" is exemplary and doesn't bode well: people who explicitly disavow a symbolic Fodorian notion of representation have to endlessly reassert this when Gibsonians are around. 😅

related diffs btwn fields I learned:

» I have a chemistry brain and a physics brain, and they will never meet each other, they will never happen at the same time...
...
and what I'm thinking of pH with my chemistry brain I think about H plus as a hydrogen ion...

if if I'm thinking about it with my physics brain I'm like that's a proton «

@DrYohanJohn @PessoaBrain @NicoleCRust @brembs Cultural and *affective* baggage to be precise 😅 It's a very good angle to raise, although any, perhaps all scientific concepts are (putatively) equally fraught with affective baggage until an empirical demonstration-based consensus is reached. Mass incl., back in its own days of ontological dispute a century or so ago. And no need to recall disputes around heliocentrism.

So are psychological terms really a special case? Or just still in dispute?

My immediate reaction is that "equally" can never be accurate. :P

List of words from Krakauer et al. (2017)

» Because little is known about how brain mechanisms bring about behaviors, neuroscientists use "filler" verbs, most of which add relatively little substantive content to the statements made. «

hehe TY now I had to lookup: open & didn't expect these fine quotes:

“…trying to understand perception by understanding neurons is like trying to understand a bird’s flight by studying only feathers. It just cannot be done”
(Marr, 1982/2010)

“Behavioral experiments often are a necessary first step before a subsequent mutually beneficial knowledge loop is set up between implementation and behavioral level work.”

” Modeling and studying the responses of the neural substrate on any scale—large or small—will not

*by itself*

lead to insights about how behavior is generated.

One reason for this is that the properties of neural tissue may be more diverse than the subset actually exploited for natural behaviors “

@teixi @knutson_brain @DrYohanJohn @PessoaBrain @NicoleCRust @brembs I know most of these papers, all very interesting. Though I'm not clear on which particular point (as there are many!) in the above discussion you're aiming your posts at..?

Fig 3 a b
unexpected discovery to me because not only applies to the neuroscience interventionist!

IMHO also applies for some critique for nowadays ai training datasets as modeling real inference hype!

from the refs: more Andersons that I didn't know ;)

#1 More Is Different:
Broken symmetry and the nature of the hierarchical structure of science.

#2 anderson perhaps listened in podcast?

do you recom other refs?

@teixi @WorldImagining @DrYohanJohn @PessoaBrain @NicoleCRust @brembs so neurobehavioral work provides understanding of causality? (strong, but I like it)

Teixi Sep 6, 2023

@knutson_brain @WorldImagining @DrYohanJohn @PessoaBrain @NicoleCRust @brembs

conclusion in abstract, not in finale:

“we argue that study of the neural implementation of behavior is best investigated after such behavioral work.
Thus, we advocate a more pluralistic notion of neuroscience when it comes to the brain-behavior relationship: behavioral work provides understanding, whereas neural interventions test causality“

difficult to get from their behavior interventionists critique

¯\_(ツ)_/¯
