Happy to share our new paper in @NatureHumBehav
nature.com/articles/s41562-0… Using 500k+ behavioral trials, we show that #serialdependence deviates from #Bayesian/optimal predictions, pointing to a new narrative about how recent experience shapes perception. @AOzkirli @ralfer

This article by @AOzkirli @ralfer and @David__Pascucci shows that, rather than improving performance, serial dependence makes perceptual decisions more uncertain. @EPFL @Brainmind_EPFL @unil @CHUVLausanne @_TheSense_

Dear friends,
We are asking for help to pursue the best possible care for Sara. If you can’t donate but still want to help, please consider sharing our campaign on any channel.
Merry Christmas, from Sara, Guido, and the rest of the Hawkins clan.

Here is a recording of my talk @CogCompNeuro last week on quantifying similarity in neural recordings
Very much enjoyed the Keynote + Tutorial format for the conference. Links to our tutorial notebook below 👇

New preprint w/ @fridaprintzlau & @KeisukeFukuda4 ! We show that attentional priority in visual working memory modulates retroactive biases in memory, *but NOT* proactive biases in perception osf.io/preprints/psyarxiv/2f… via @OSFramework

New preprint out🚨 with @SamsonChota @LUZIXU1 @SvanderStigchel @SuryaGayet, titled “The priority state of items in visual working memory determines their influence on early visual processing”

Are you looking for a precise monitor for vision science, eye-tracking, or EEG? In a new preprint, we tested an interesting new display option with excellent timing performance: "High-speed" organic light-emitting diode (OLED) monitors. A summary:🧵[1/n]

All kinds of exciting plans are afoot here @JohnsHopkins, and this is part of it! Three positions in Psychological & Brain Sciences — one each in cognitive psychology, cognitive neuroscience, & behavioral neuroscience. These are very broad searches (in both rank and area). Apply!
🚨 Johns Hopkins psych & brain sci is hiring! 🚨
TWO open-rank faculty positions: one in cognition, broadly construed, the other in cognitive neuroscience
We're excited about lots of research areas & approaches, including development & animal cognition!

Deep in thought while on your way to work? Better watch out, could be a recipe for disaster! Yet, people are able to daydream and hold images in mind effortlessly, with eyes open. But when you also need to attend your surroundings, it gets tricky… Why? 🚨TWEEPRINT ALERT! 🚨1/n

Another study highlighting that visual findings from mice don't generalize to primates.

2 thoughts:
1) It's fascinating that mice have no orientation columns - architectural constraints?
2) It's crazy nobody has directly shown orientation columns in humans

TUS holds great potential for neuroscience and clinical applications, but its success requires careful control for peripheral confounds. Let’s ensure noise doesn’t derail this powerful technology! Check out our eLife paper: doi.org/10.7554/eLife.88762.… Thread below 👇

📰New paper! Our perception, thoughts, and behavior are shaped by recent events, a phenomenon called serial dependence.
But what modulates it? 🤔

A systematic dissection of the analogue report methodology and comparison with "gold-standard" 2AFC. Key findings: motor noise is negligible; analogue report error is a robust measure of memory fidelity, but may underestimate perceptual precision doi.org/10.3758/s13428-024-0…

It has been proposed that schizophrenia patients rely more on sensory input and less on prior information. According to this view, they are less affected by visual illusions that rely on perceptual priors. But is this really true?(shorturl.at/jmhKv) 1/6🧵

Here we @jalewpea show that the integration of history responses and memory contents can lead to both serial dependence biases and stabilization in working memory. jneurosci.org/content/early/…

"A random half of panelists were shown a CV and only a one-paragraph summary of the proposed research, while the other half were shown a CV and a full proposal. We find that withholding proposal texts from panelists did not detectibly impact rankings."
