This whole project stemmed from a conversation with @brainscout.bsky.social several years ago. Sorry it took me so long to write it up!

As targets are forgotten over a week, this pattern becomes more pronounced. All this indicates that mnemonic discrimination performance depends on both the strength of the target memory and the similarity of the lure to the original target.

lures successfully with high confidence, especially when the lures are not very similar to targets. However, when lures are highly similar, they false alarm (call them "old") with high confidence. Consequently, we see that low-confidence responses are _more_ accurate than high conf. for those items

We found people forget! Which of course we were expecting (Ebbinghaus showed the forgetting curve in 1885). What's interesting is that as people forget the original targets, their responses to the similar lures change in interesting ways. When target memory is strong, people are able to discriminate

We had participants complete the Mnemonic Similarity Task (MST) where they study everyday objects and then take a recognition memory test with exact repeats, similar lures, and novel items. Usually, we only wait a couple minutes between study and test phases, but here we included delays up to 1 wk

Preprint day! Mnemonic discrimination is required to keep overlapping or similar experiences from interfering with each other in memory. We've done a lot of work on how this happens at short delays, but we've never examined this process at longer delays, like over a week

Hajrá magyarok!

Definitely reach out if you’re interested and want to know more.

I promise I’m a good officemate :)

Honestly this is a boss move. I’m going to try it from now on

I “liked” this post but I do not like this post

These findings suggests that individuals with T1D likely exert greater neural "effort" in executive functioning-related brain regions to achieve similar levels of inhibitory control when compared to peers without T1D.

We found T1D S's demonstrated similar behavioral inhibition performance to controls but comparatively greater activation in several interconnected executive functioning-related brain regions. We did not find an association between hemoglobin HbAlc and executive function-related neural activation 2/3

New paper! Emerging adults with type 1 diabetes have been shown to have poorer executive control and working memory performance compared to controls. With Chad Jensen's lab we examined executive control in emerging adults with T1D using fMRI. 1/3

Congratulations! Well deserved

Penn people can stop in anytime from 3-5 PM this Weds-Fri to make a sign/poster in our 200 Goddard Suite.

We will have cardstock and large markers available. You bring the smart arguments.

activation in frontal and parietal regions including DLPFC and DMPFC. We think this suggests conflicts between incoming information and prior attitudes engage effortful, higher-order cognitive systems rather than affective processing. Resolving such conflicts appears to rely on decision-making 5/6

analyses on the pro-vax group. Based on prior misinformation fMRI studies, we hypothesized activation in amygdala & precuneus when Ss read vax misinfo. We didn't see that. Instead, when Ss made attitude incongruent judgments (i.e., endorsing misinformation or rejecting correct information) we saw4/6

in the 2022-23 academic year while the university had a vaccine requirement to be on campus (so all our subjects had rec'd COVID19 vaccinations). This is perhaps why we had a hard time recruiting anti-vax folks (so all analyses with that group should be considered preliminary) & we focused 3/6

This was first author Morgan McClellan's undergrad Sr. thesis where she wanted to characterize the neural response to pro- and anti-vaccine statements in people selected for their prior attitudes (both for and against COVID19 vaccination). For context, we recruited from the BYU community 2/6

Opinion | The Multi-Trillion-Dollar Battle for Your Attention Is Built on a Lie

Oh, and link to the original piece: www.nytimes.com/2026/01/10/o...

and it is really a thing that can be measured (and thus monetized). I do agree with the authors that our phones are making us less present in the moment, but I'd call that "attentiveness" rather than attention per se. I do find it ironic that the NYT gave such a clickbaity headline to this piece 🤷‍♂️

the authors contend that what gets called "attention" is not really real attention, which is more about being present in the moment. They support this assertion by tracing the history of research on attn in cognitive psychology. By objection is that cog psych does a good job defining attn ...

There was an Op-ed in the New York Times this weekend about how the "attention" in the attention economy isn't what you're told that it is. As a cognitive neuroscientist, I'm interested in cognitive processes like attention, so I read it. I have thoughts, shared here: brockkirwan.com/uncategorize...

Overheard while boarding the red eye flight last night:
Toddler: what does “red eye mean”?
Dad: it means this is a flight in the middle of the night. We’re all going to sleep on the flight—mommy, daddy, you. We’ll all sleep.
Toddler: will the pilot sleep?
