From 42 to HMM: An integrative neuroscience theory of the mind

In his seminal work of science fiction, A Hitchhiker’s Guide to the Galaxy, Douglas Adams ponders a question, which turns out, unsurprisingly, to be difficult to answer: What is the meaning of life, the universe, and everything? In the novel, a super-intelligent civilization builds a super-computer to answer the question. That super-computer cannot answer the […]

From data to information: The functional brain network integrating memory with reward

I sometimes wish I had perfect memory. No more missed appointments! I’d never misplace my phone (it’s always on my bedroom dresser). And I’d always remember the name of that actress (whats-her-name, in that thing!), or my colleague (sorry….), or my friend (really??). Yep, life would be pretty sweet. Despite these fantasies, individuals with highly-superior […]

The revolution will not be alphabetized: Alphabetizing in-text citations biases citation rates

Imagine a world in which Einstein crafted his general theory of relativity – discovering and codifying the laws that govern light, space, and time – then went about his life, never publishing, and never telling another person. It may seem obvious, but scientific knowledge, in order to influence the generation of future scientific knowledge or […]

As easy as Do-Re-Mi: Is there a correlation between musical ability and executive function?

Musical training encompasses a broad range of skills, which likely rely on a similarly large range of cognitive abilities. Consider the act of sight-reading, in which a musician plays from a piece of sheet music they have never seen before. The musician must read the upcoming notes (a feat of translating visual information into a […]

First-case scenario: Primacy effects depend on reading direction

How many U.S. presidents can you name? (Apologies to our international audience.) Regardless of how many you can recall, I would bet that among the ones you did remember are Washington, Adams, Jefferson, Trump, Obama, and Bush. I would also bet that among the ones you did not remember are McKinley, Hoover, and Cleveland. Don’t […]

“It’s me”… When “it” could be anyone between Seinfeld and Philadelphia

Remember answering machines? Me neither, but this is why Seinfeld exists. When Jerry’s girlfriend, Sophie, leaves a message without stating her name (just, “it’s me!”), Jerry decides to call her back without stating his own name. Stripped of visual and contextual cues—Jerry’s face, what he’s wearing, his name—Sophie fails to identify him by just his […]

One for the money, one for the show: Neural activation changes when intending to gamble on versus intending to watch soccer

On Monday, May 14th, 2018 the US Supreme Court effectively legalized sports gambling. Of course, prior to that ruling, sports gambling had been possible in the US, in various forms, online (one-day fantasy sports contests, like DraftKings) and through offshore betting venues. While fans had ample opportunity to wager on the performances of individual players […]

How the takete got its spikes: Why some words sound like what they are

Human beings have an incredible capability to communicate. Unlike other species, humans have evolved to use language to express our states, desires, observations, and, I guess, tweet about them. Language is a powerful system of communication because it allows the expression of counterfactuals: we can easily discuss the past and future; distant, unseen locations; complex […]

Knowledge is (still) power: Memory for chess positions is better for experts with more chess knowledge and chess experience

Memory researchers love chess. Chess experts have been studied by psychologists to try to explain the role of higher-level processing in memory. One reason chess is a great domain in which to ask these questions is because its rules and concepts provide meaning to the spatial positions of the pieces only if one knows them. […]
