New episode about the thing that happened, the reaction to it, and the reaction to the reaction to the thing that happened.

A new addition to my personal library, thanks to Bluesky's #visionscience community (even if in the sequence of a sad new).

So, basically - and for those who didn't know it - yes, trans people exist and they are like anyone else: they love, they smile and cry, they care for their loved ones, they collaborate with authorities, and (importantly) they DID NOT incite violence. Can media stop talking about trans now?

Thank you all for the great feedback and insightful questions on my poster "Exploring Action-Specific Effects: A Representational Momentum Study of the ‘Pong Effect’" at #ECVP2025. It was a wonderful conference and I am already looking forward to the next one!

Shout-out to Rodrigo Freita's presentation of our work "Dynamic events as a natural cause for the Onset Repulsion Effect" at #ECVP2025. We had a great feedback and fruitful discussions.

It's taking me forever to read this book because my brain insists in emulating Bernie's distinctive voice tone...

I find it particularly funny how it always seems to be in a rush to plot stuff and you have to keep telling it to "hold on" XD

Here's our new episode about that guy trying to talk. Alternate title is "The Right-Wing War On Words", but we couldn't resist.

Yesterday was our "Illusion Day", with interactive demonstrations of classic perceptual illusions made by my students of Attention&Perception. It was the first time I attempted this activity with a class and it was definitely a success! Will repeat it next year! (more illusions in the comments)

It is my conviction that the time required for a Matlab script to finish is directly proportional to its understandability (or, stated differently, the most efficient scripts are necessarily more obscure and harder to understand)

This is the output of my modest Matlab implementation of Marr&Poggio's cooperative algorithm for stereo disparity.
With less than 100 lines of code, it is not efficient, the parameters need to be tweaked for each simulation and only works in Flatland, but it makes the core ideas clear for students.

From the questions to the cuts. What is happening between the USA and Portuguese universities? - PPulse The United States is withdrawing support previously provided to several Portuguese universities and has issued questionnaires to these institutions concerning

Trumps' administration rescinded a program with Portuguese Universities (including the one where I work) along with a questionnaire on ideological issues (women's rights, equity, inclusion, global warming, etc), hinting that continuation of the program hinges on giving the "right" answers... 😡

😅

Well, I "stole" two coloured balls from my toddler to use as part of one experiment we're about to run...

When your father is a vision scientist and has a knack for building classroom perception demonstrations...

Also, the pinhole must be really tiny, otherwise it really doesn't work unless the person looks at it the right way... Other than that, it's just a box divided into two sections - the farthest one with no ceiling (to allow the light inside)

@bjbalas.bsky.social , thank you! :) To be honest, this was just a first attempt, with lots of improvising as I went along. I learned that it is much easier to make the pinhole first and glue the bits of paper afterward (while peeking through the hole).

In preparation for my Perception class this next week, on lightness and colour constancy, I made a cardboard model of the 1977 Gilchrist's experiment.

Well, at least, exercise wise, Republicans are done for the week. No need for more squats in the next few days. #stateoftheunion

Was about to say that, at least, every sane person would have a 1/3 chance of guessing correctly - but yeah, we all know which of those 3 you're talking about.

His attire would be much less of an issue if it included a black hat and a child on his back...

me too.

Like much of the world, I’m struggling to make sense of Trump right now.

Is it the minerals? Then he’s just greedy.
Zelensky’s popularity? Then he’s petty and envious.
Putin’s leverage? Then he’s a coward.
A MAGA stunt? Then he’s just a clown.

The saddest part? It is probably all of the above...

In response to Trump's actions, I've seen lots of comments like "Can you imagine if it was Biden?".
Well, yes, yes I can imagine! And not seeing any reaction anywhere near what I can imagine is baffling!
Granted, I'm following all this from afar and through the lenses of social media, but still...
