Do You Agree? Do You Strongly Agree? The Effect of the Number of Response Categories on Response Processes and Verification of Substantive Hypotheses Abstract. This study investigates how the number and labeling of response categories in survey scales affect respondent behavior, psychometric properties,

This is consistent with earlier psychometric work that suggests 5-7 is the best response scale options, but good to see that the finding holds up in contemporary research. Also, good to see that labeling scales whether anchored or not has little impact on findings. academic.oup.com/ijpor/articl...

The inferred value of unchosen options spreads to related items in memory Counterfactual thinking — considering what could have come of choosing the other path — can facilitate inference. Previous studies have demonstrated t…

📢New paper out today in @cognitionjournal.bsky.social!

Does the value of an unchosen option — inferred through counterfactual reasoning — spread to related items in memory, similar to how the value of a chosen option — acquired through direct experience — does?

In short, yes!

Deciding for others alters metacognition leading to responsibility aversion Making decisions on behalf of other people reduces decision confidence, which leads to responsibility aversion.

When we have to make a decision that affects other individuals—parents making decisions for children, for instance—our confidence in our decisions declines, making us averse to the responsibility.

I do have a brand :-)

Want to use the word cromulent when, as a reviewer, authors send in replies that address my concerns, but don't assuage them.

"I found the author's response cromulent"

It means adequate, but it doesn't sound like that's what it means.

So excited about this preprint: Bottom-up and generative computations uniquely explain neural responses across the social brain

This is a robust response. I particularly liked this figure - clarifying why the original critique showed what it did, and what was missing @foxmdphd.bsky.social

Do our social interactions influence what we become aware of?

In our❗new preprint❗@danieljamesyon.bsky.social and I delve into this question: asking whether joint decision making in a detection task can bias awareness reports.

Another excellent paper from benjyb.bsky.social showing how we align our perceptual judgements with others. Read and love it, and I trust you are already aware of this.

Why are tactile sensations suppressed during movements? In our new preprint, we explain this as optimal integration of sensory signals with an internal model.

A recent paper in @natureportfolio.nature.com raised concerns about the lesion network mapping method. Our team of 16 coauthors analyzed >1000 lesions and 34 symptoms and found that "The methodological foundations of lesion network mapping remain sound" www.biorxiv.org/content/10.6...

Compact deep neural network models of the visual cortex Nature - Parsimonious deep neural network models can be used for prediction of visual neuron responses.

DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico?

In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony.

It turns out these compact models are surprisingly small!

Very excited to have received a Vici grant for the project "Doing Science Differently? A Philosophy of Transgressive Science". The project will address methodological & institutional challenges of transgressing "business as usual" in academia. www.wur.nl/en/news/davi...

Congratulations all! Do you have thoughts on (non-synaptic) mechanism? Ion channels shuttled in / out of the membrane perhaps?

After several years of work, my lab is starting to put out our first papers on learning in a unicellular organism (Stentor coeruleus).

Here we show evidence for a form of associative learning in Stentor:

We’re all familiar with having to practice a new skill to get better at it, but what really happens during practice? The answer, I propose, is reinforcement learning - specifically policy-gradient reinforcement learning.
