Last week I had the pleasure of visiting the Centre for Brain Research at the Jagiellonian University in Krakau, and giving a talk at the Institute of Psychology! Thank you very much @marekpedziwi.bsky.social and @antoniafranaszek.bsky.social for the invite and interesting discussions!

End of August means ECVP! This year, I am here (in beautiful Mainz) with a special mission - to find postdocs who will join us in (equally beautiful) Krakow, PL! Drop me a DM if you are interested! @ecvp.bsky.social

The further a researcher or inventor moves from their previous work, the less cited their latest work will be go.nature.com/44VjEW9

Shifting research focus comes with the risk of reduced impact
An analysis of millions of scientific papers and patents shows that the further a researcher or inventor moves from their previous work, the less cited their latest work will be.

Does anyone know of open datasets where people have asked participants to explicitly define non words? We are pulling together an experiment now and hoping to r/o iconicity and wordlikeness as content drivers

curious what real outcomes this transformation is associated with. is the overall research quality better? do people ask better questions or design better studies? are more results reported in titles, abstracts, & media valid or measured? do fields move forward faster or more effectively? etc.

Two common findings from sleep research are that 1) short sleep durations predict worse health outcomes, and 2) people from some cultures sleep much less than those from others. Do people from cultures with short sleep durations have worse health outcomes? 🧵

Our research shows that ~50% of mothers globally decline at least half of opportunities to participate in conferences after becoming parents (N=3995). We understand the barriers and are offering Travel Grants to help overcome these challenges. Apply now - deadline 31st March! shorturl.at/gnCU2

Do you or anyone you know have a template/code for an e-prime experiment that integrates with a Smart Eye eye-tracker? I just realized I may save a lot of time if one of you just happens to have any example I can borrow from. Also: any leads would be appriciated. GIF of cat tracking for attention

In this review article, I summarize some of our recent work on the neural basis of visual search in scenes, showing how attention and expectation interactively drive preparatory activity in visual cortex and jointly modulate the visual processing of potential target objects. doi.org/10.1177/0963...

Does cultural experience shape visual perception? New research finds "profound differences in visual phenomenology, with rural Namibian participants often failing to see percepts obvious to UK/US participants and vice versa." Preprint: doi.org/10.31234/osf...
Abstract: Vision science largely ignores the fact that rural visual environments typical of our species’ history differ radically from urban zones from which almost all samples are drawn: Only a handful of paradigms have been used to investigate rural-urban differences in visual perception, and some show limited effects or suffer from limited methodologies. Here we more than double the total number of paradigms in this literature, including visual illusions assumed to rely on universal mechanisms (e.g. Gestalt shapes, Cafe wall, curvature blindness). Results reveal profound differences in visual phenomenology, with rural Namibian participants often failing to see percepts obvious to UK/US participants and vice versa. In sum, what is universal and what is culturally-constructed in human visual perception remains a wide-open area of research.

Can anyone point me to a resource of open datasets from psychology? I am looking for ways to improve a psychology stats course for next year (based on Statistical Rethinking by @rmcelreath.bsky.social), and one way might be to offer more psychology-specific examples for the practical sessions.

A student asked me the other day whether I had major career ambitions like winning a big award. I told him that my goal was to do interesting things and have fun. I worry that young scientists don't see their jobs as fun... too much pressure. But then what's the point, really?

Humans use language to express thoughts primarily built around the basic agent-patient causal structure *who does what to whom* Is this a structure of language or a structure of thought? Does it exist outside language? A new wave of exciting papers speak to this question. A 🧵👇

I am not attending #VSS2024, but I am joining the trend of advertising one's work under this hashtag! In the recent JoV paper (jov.arvojournals.org/article.aspx...), we used Hitchcock's films to show 1️⃣ how disrupting a visual narrative alters gaze and 2️⃣ why using hidden Markov models is tricky. #VSS

Predictions of eye movements when viewing images should work well for all. Do they? We studied this with gaze data from >2,000 participants collected in the Nemo museum Amsterdam! Out in Communications Psych t.ly/Y1-Ty tldr: models do well, especially if you are a psychology student More:

The dominant diagnosis seems to be that this is evidence of a broken science. An alternative diagnosis is that if we really expected a single set of results from these 246 unique situations, we have broken our understanding of science. #STS #metascience #philsci
