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

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

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 πŸ€·β€β™‚οΈ

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 ...

Attention is not the same as attentiveness – Brock Kirwan

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 β€œred eye mean”?
Dad: it means this is a flight in the middle of the night. We’re all going to sleep on the flightβ€”mommy, daddy, you. We’ll all sleep.
Toddler: will the pilot sleep?

A charity offered free MRIs to screen for brain cancer. Doctors worry they’re not worth the risks. The Brain Tumor Foundation has been holding free screening events for more than a decade in hopes of promoting early detection of brain tumors. Doctors worry the risks outweigh the benefits.

Super interesting article in today's Philadelphia Inquirer about regular MRI screenings for brain tumors & other injuries. In my experience, we see an incidental finding in maybe 1/1000 cases, but I scan healthy young adults at low risk for these things. What do you think? share.inquirer.com/kHZkTn

This is awesome. Drag and drop a brain MRI scan into the window and it does tissue segmentation in the browser (in about 8 seconds), then creates a 3D mesh suitable for 3D printing. This has been an hours-to-days long process for us in the past, all in a couple minutes. 🀯 brain2print.org
