New preprint using dynamic causal modelling during inattentional blindness where we show support for both sensory and frontal theories of consciousness with Elise Rowe and @MartaIGarrido 🙂

Nice quick read with an important point: even if a model predicts brain data well it doesn't mean the model uses the same mechanism the brain does. More expressive models generally do better than less expressive models regardless of mechanism.
My 2nd to last #neuroscience paper will appear @unireps !! 🧠🧠 Maximizing Neural Regression Scores May Not Identify Good Models of the Brain 🧠🧠 w/ @KhonaMikail @neurostrow @BrandoHablando @sanmikoyejo Answering a puzzle 2 years in the making https://t.co/jVs18MDJt0 1/12

Joe Melling et al. investigate a novel visual illusion in which moving frames cause a single flashed stimulus to be perceived in two locations simultaneously, https://t.co/A26z8wvLL4.

Do persons with Autism Spectrum Disorder show disrupted Bayesian integration of perceptual priors and sensory likelihoods? Intruiging new psychophysical study suggests they do not. https://t.co/gaUfb7z4N2

@renrutmailliw @violetjchae @ceptional @HinzeHogendoorn We find no evidence supporting the idea that discrete sampling at alpha frequency is a mechanism of these illusions.

Super excited to share the latest preprint from my PhD! With @renrutmailliw @violetjchae @ceptional @HinzeHogendoorn we show that individual alpha frequency does not index a mechanism underlying motion-position illusions (e.g., the flash-lag effect). https://t.co/VOd0EPuyGu

Motion-Position Illusions (MPIs) involve the position of an object being misperceived in the context of motion (i.e. when the object contains motion, is surrounded by motion, or is moving). A popular...

I procrastinated again by starting a tutorial on "cognitive models" (stats models that fit well reaction time data) in #Julia
https://t.co/NPDPstTGdG I'm quite happy about the animations I managed to make. Julia has a lot of potential!

You may remember this pretty figure summarizing how tweaking pre-processing and analysis can affect study outcomes, effect size, and statistical power of an ERP study. Now you can find it in Psychophysiology: https://t.co/8biyGoxugQ

In our new review, we discuss how aiming for the best answers leads to inconsistent perception: https://t.co/2fQYkNIBnf In this digest, I will present some examples. The first is that the Brentano illusion affects the length (green) of a line, but not the endpoints (blue) (1/5)

Happy to share this brief preprint w/ Oh-Sang Kwon, Minwoo Kim & @HinzeHogendoorn. We suggest that the brain may be able to rapidly re-weight its inputs and predictions during perceptual inference, explaining the puzzling phenomenon of 'position resets'. https://t.co/ozxZ85aXPy

Inspired by recent preprint failing to replicate some of our earlier findings, we just did a study that suggests: 1. Some (but obv not all) size illusions -do- share common mechanisms. 2. It really does matter -how- you measure the illusion strength. https://t.co/fIBKPmi2IY
