I wish I had learned unicycling back when I was jugging a lot more, but I fear it's too late for me - my balance isn't what it used to be.

I didn't manage to mention that one, but did mention the money money tree and the psychology research sidewalk placard. Really disappointed that you weren't the one on the unicycle :-(.

The paper cites some of the marketing hype, so that might count as one form of "popularization." There are papers by Dan Hurley (journalist) touting brain training, and plenty of blog posts from people associated with the brain training companies making unsubstantiated claims.

Does that mean you allocate two class meetings for each exam? Do you have to scale back on content then?

That is a really large implicit effect, especially given the lack of much evidence for semantic priming… but I haven’t read the paper yet.

Daniel Simons @profsimons.bsky.social · 12/10/2025
There are other ways of inducing change blindness of that sort. E.g. the ducking behind a counter version. Yes, the nature of giving directions varies by setting. Different task in Ithaca and Boston.

Daniel Simons @profsimons.bsky.social · 11/10/2025
It's possible. That person change does show an ingroup-outgroup effect, so maybe there would be cultural differences in that sort of connection. I imagine the context (e.g., a person change in a bar) would drive it more than East/West diffs. That's my guess, anyway.
120
Daniel Simons @profsimons.bsky.social · 10/10/2025
Doubt it, but could be wrong. People are always doing *some* task. If the change is unexpected, it seems unlikely that whatever "task" people are doing will happen to differ by culture in ways that affect change detection. Might differ for deliberate detection tasks because strategies might vary

Here are the DOIs for the handful of ADHD ones we turned up in our preliminary, non-systematic search: 10.1177/1087054711433294 10.1016/j.ridd.2015.12.002 10.4992/pacjpa.73.0_1AM031 doi.org/10.3389/fpsy... We likely missed some. I haven't read any of these closely yet.

Daniel Simons @profsimons.bsky.social · 10/10/2025
My lab has started a change blindness lit review this semester. Our preliminary search (not systematic) turned up a few papers on ADHD (DOIs in next reply), I haven't examined them for quality. We're starting a systematic review on change/inattentional blindness and autism first.

Daniel Simons @profsimons.bsky.social · 10/10/2025
Will do. The Stage 2 RR is ready to submit now but will be submitted next week (after OSF finishes updating to their new interface). I'll send the meta-analytic review paper and the cultural diffs paper.

Daniel Simons @profsimons.bsky.social · 10/10/2025
But we don't find cultural differences in intentional change detection tasks either: journals.sagepub.com/doi/full/10....
050
Daniel Simons @profsimons.bsky.social · 10/10/2025
I wouldn't expect cultural differences for IB (we haven't found those either). I think the same would be true for unexpected changes like the "door." I suspect that individual differences in other cognitive ability measures *are* associated with performance on intentional change detection tasks.
250
Daniel Simons @profsimons.bsky.social · 10/10/2025
Hi folks. For inattentional blindness, individual differences are limited at best. We did a meta-analytic review and found little or no association with working memory measures, etc. We're about to submit a stage-2 RR also showing little evidence of individual differences in IB.

I don't think I have one. Somewhere in my lab I have an old videotape from Dick Neisser. If I can find it, I'll have it digitized professionally. I don't think the Neisser & Becklen (1975) videos were, though. Maybe @irahyman.bsky.social has that one? Happy to post other variants to my channel.

I used to have it up there. Not sure why I don't any more. For a while, I was handling requests for it for Dick's children, but I haven't needed to do that for a while. I'd be happy to repost it if you think that would be best for visibility.

My editorial on how journals can earn trust. We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that. journals.sagepub.com/doi/full/10....

One thing I wish I saw more from communicators especially on health & medicine: Let's be more vocal about the positives of interventions that work. Yes, it's important to push back on misinformation, poor research practices & clarify side effects. But let's not forget how important this all is.

Here's a fun way to encourage students to always look at their data. A few years ago, I wrote a script that converts a black and white png to data and plots it.
Plotted version of png converted to data with regression fit line. It appears there's a positive association between steps and sleep. But the simulated data points spell out "OH NO!"Png showing "OH NO!" in black letters on white background
