Bookmarked Visual and auditory brain areas share a representational structure that supports emotion perception by Beau Sievers, Carolyn Parkinson, Peter J. Kohler, James M. Hughes, Sergey V. Fogelson, Thalia Wheatley (Current Biology)
Emotionally expressive music and dance occur together across the world. This may be because features shared across the senses are represented the same way even in different sensory brain areas, putting music and movement in directly comparable terms. These shared representations may arise from a general need to identify environmentally relevant combinations of sensory features, particularly those that communicate emotion. To test the hypothesis that visual and auditory brain areas share a representational structure, we created music and animation stimuli with crossmodally matched features expressing a range of emotions. Participants confirmed that each emotion corresponded to a set of features shared across music and movement. A subset of participants viewed both music and animation during brain scanning, revealing that representations in auditory and visual brain areas were similar to one another. This shared representation captured not only simple stimulus features but also combinations of features associated with emotion judgments. The posterior superior temporal cortex represented both music and movement using this same structure, suggesting supramodal abstraction of sensory content. Further exploratory analysis revealed that early visual cortex used this shared representational structure even when stimuli were presented auditorily. We propose that crossmodally shared representations support mutually reinforcing dynamics across auditory and visual brain areas, facilitating crossmodal comparison. These shared representations may help explain why emotions are so readily perceived and why some dynamic emotional expressions can generalize across cultural contexts.
This portends some interesting results with relation to mnemonics and particularly songlines and indigenous peoples’ practices which integrate song, movement, and emotion.

Read Talking out loud to yourself is a technology for thinking by Nana Ariel (Psyche)
Talking out loud to oneself is a technology for thinking that allows us to clarify and sharpen our approach to a problem

I ran across this article this evening and some of the ideas resonate strongly with me. The article mentions some areas of psychology research and a few papers I hadn’t seen before.

I’m also particularly interested in the idea of embodied cognition within cognitive psychology. Has anyone delved into these areas in their research or memory-related work? @LynneKelly’s research and written texts encourage singing, dancing and performing (I don’t recall specifically speaking or walking in her contexts, but I’m sure they’re all closely related), but has anyone else experimented with these additional modalities in their practice?

Most of the Western-based mnemotechniques I’m aware of are focused almost solely on internalized speech/thought. Can anyone think of any which aren’t?

I’ve seen several works in which Nassim Nicholas Taleb propounds the benefits of the flaneur lifestyle for improving thought, though his mentions are purely anecdotal as I recall. I’d appreciate any additional references to research in these areas if others are aware.


Like many of us, I talk to myself out loud, though I’m a little unusual in that I often do it in public spaces. Whenever I want to figure out an issue, develop an idea or memorise a text, I turn to this odd work routine. While it’s definitely earned me a reputation in my neighbourhood, it’s also improved my thinking and speaking skills immensely. Speaking out loud is not only a medium of communication, but a technology of thinking: it encourages the formation and processing of thoughts.

I’ve noticed speaking out loud also seems to help me in practicing and acquiring a new language.

The idea that speaking out loud and thinking are closely related isn’t new. It emerged in Ancient Greece and Rome, in the work of such great orators as Marcus Tullius Cicero. But perhaps the most intriguing modern development of the idea appeared in the essay ‘On the Gradual Formation of Thoughts During Speech’ (1805) by the German writer Heinrich von Kleist. 

Some of this is at play with the idea of “[rubber ducking](https://en.wikipedia.org/wiki/Rubber_duck_debugging)” as a means of debugging programs

In both cases – speech and writing – the materiality of language undergoes a transformation (to audible sounds or written signs) which in turn produces a mental shift. 

There’s surely a link between this and the idea of thought spaces in the blogosphere or the idea of a commonplace book/digital garden/wiki.

Mute inner speech can appear as an inner dialogue as well, but its truncated form encourages us to create a ‘secret’ abbreviated language and deploy mental shortcuts. By forcing us to articulate ourselves more fully, self-talk summons up the image of an imagined listener or interrogator more vividly. In this way, it allows us to question ourselves more critically by adopting an external perspective on our ideas, and so to consider shortcomings in our arguments – all while using our own speech. 

I’m also reading this and wondering about memory techniques and methods and how these may interact beneficially.

It’s no coincidence that we walk when we need to think: evidence shows that movement enhances thinking and learning, and both are activated in the same centre of motor control in the brain. In the influential subfield of cognitive science concerned with ‘embodied’ cognition, one prominent claim is that actions themselves are constitutive of cognitive processes. That is, activities such as playing a musical instrument, writing, speaking or dancing don’t start in the brain and then emanate out to the body as actions; rather, they entail the mind and body working in concert as a creative, integrated whole, unfolding and influencing each other in turn. It’s therefore a significant problem that many of us are trapped in work and study environments that don’t allow us to activate these intuitive cognitive muscles, and indeed often even encourage us to avoid them. 

I’m curious if Lynne Kelly or others have looked into these areas of research with their Memory work? She’s definitely posited that singing and dancing as well as creating art helps indigenous cultures in their memory work.

👓 How the media should respond to Trump’s lies | Vox

Read How the media should respond to Trump’s lies by Sean Illing (Vox)
A linguist explains how Trump uses lies to divert attention from the "big truths."
I like that he delves into the idea of enlightment reasoning here and why it doesn’t work. This section of this article is what makes it a bit different from some of the interviews and articles that Lakoff has been appearing in lately.

Highlights, Quotes, Annotations, & Marginalia

I take your point, but I wonder if Trump is just kryptonite for a liberal democratic system built on a free press.  

The key words being “free press” with free meaning that we’re free to exert intelligent editorial control.

Editors in the early 1900’s used this sort of editorial control not to give fuel to racists and Nazis and reduce their influence.Cross reference: Face the Racist Nation from On the Media.

Apparently we need to exert the same editorial control with respect to Trump, who not incidentally is giving significant fuel to the racist fire as well.

A lot of Democrats believe in what is called Enlightenment reasoning, and that if you just tell people the facts, they’ll reach the right conclusion. That just isn’t true.

Read Power Causes Brain Damage (The Atlantic)
How leaders lose mental capacities—most notably for reading other people—that were essential to their rise
This is an impressive thesis and area for research. I’m impressed with their restraint in not making a single mention of Donald Trump here who would be a sterling example, particularly given his background, bullying behavior, and complete lack of any empathy.
