This thread is making me think critically about ongoing work with @AlbertoParola2 and separately with @ethanweed. After looking meta-analytically at vocal markers of psychiatric conditions, we launched projects to systematically replicate and extend them cross-linguistically 1/n
Is there a distrust? Possibly some, looking at the studies and at effect sizes of "1.89". Should there be? I'm not sure. I mean I'd really want to be able to build on these findings to better understand the underlying mechanisms. 2/n
and that's where it stroke me. This work shouldn't stand on its own, but with much needed complementary work on the mechanisms underlying the phenomenologically clear atypicalities (and what they can do in helping us to understand the conditions). Without that, 3/n
it has (I have) a hard time going beyond an underground layer of distrust. However, the metawork is "easier" than the theoretical work and got prioritized (plus there is my personal interest in understanding dynamics of knowledge formation in the field).

The Puzzle of Danish: a thread on taking linguistic diversity seriously to highlight the flexibility of human cognition.
1/n
TLDR: Danish has an unusual speech opacity (consonant reduction). Danish native speakers rely more strongly on context and top-down inference. They also create more redundant speech and repeat each other more: a richer context for top-down speech processing. 2/n
Are dyads better at categorizing than individuals? In this paper (psyarxiv.com/qs253, w @kristian_tylen, Smith and Arnoldi) we developed a new paradigm relying on these cute aliens. Participants (alone or chatting with another participant) have to
figure out whether the aliens are dangerous or not & whether they can obtain precious resources from them or not. The categories are - unknown to the participants - based on combinations of visible features (e.g. arms up and/or big eyes) with different levels of complexity.
Dyads seem better at figuring out which aliens are what, across levels of complexity.
Read "Cross-linguistic differences in categorical perception: Comparison of Danish and Norwegian" by outstanding @byureka (@PuzzleOfDanish), testing the hypothesis that Danish's reduction of consonants makes Danes more reliant on context 1/n psyarxiv.com/jpbtw/
The team (also involving Højen, @kristian_tylen, @MH_Christiansen and me) cleverly tweaked categorical perception paradigms to compare how native speakers of Danish and of Bokmål Norwegian (akin to Danish, but with less reduction) combine acoustic information from the phoneme 2/n
with semantic information from the sentence containing the word. Using Drift Diffusion Models (with tips from @HenrikSingmann) to combine response and reaction times @byureka shows native speakers of Danish wait longer for relevant context and rely more on it than Norwegians 3/n

Lessons learned while evaluating academic job applications: 1/n
In the cover letter explicitly write a paragraph for each of the assessment foci (research, teaching, etc). So much easier to navigate for the assessors. Also it possibly enables you to frame/prime how that paragraph is going to be written in the assessment 2/n
If you state something in a cover letter (e.g. experience in Bayesian Jedi approaches to dark-matter-enabled-brain-scanning) do make sure it's reflected in your other materials (e.g. courses/papers/training/etc), maybe even point to that. Hard to assess it otherwise. 3/n
Next week in my Social and Cultural Dynamics course we move to game theoretical approaches to social interactions. The goal is to compare and complement social cognition and game theoretical approaches 1/n
Social cognition providing models of cognitive mechanisms for processing information, making decisions and interacting; game theory providing a decidedly interpersonal perspective, and a strong incentive-based perspective (nb. not necessarily economic incentives) 2/n
guest-starring a discussion of how traditional cognitive phenomena (ToM) can be tackled from a game theoretical perspective. 3/3
