Scientific American reports on a new study that may ‘intrigue’ you:

“Neuroscientist Charan Ranganath and his fellow researchers asked 19 participants to review more than 100 questions, rating each in terms of how curious they were about the answer. Next, each subject revisited 112 of the questions—half of which strongly intrigued them whereas the rest they found uninteresting—while the researchers scanned their brain activity using functional magnetic resonance imaging (fMRI).

During the scanning session participants would view a question then wait 14 seconds and view a photograph of a face totally unrelated to the trivia before seeing the answer. Afterward the researchers tested participants to see how well they could recall and retain both the trivia answers and the faces they had seen.

Ranganath and his colleagues discovered that greater interest in a question would predict not only better memory for the answer but also for the unrelated face that had preceded it. A follow-up test one day later found the same results—people could better remember a face if it had been preceded by an intriguing question. Somehow curiosity could prepare the brain for learning and long-term memory more broadly.”

The highlights of this research by Charan Ranganath and his fellow researchers are:

• People are better at learning information that they are curious about
• Memory for incidental material presented during curious states was also enhanced
• Curiosity associated with anticipatory activity in nucleus accumbens and midbrain
• Memory benefits for incidental material depend on midbrain-hippocampus involvement

So, curiosity may kill the cat, but also may help your pupils to learn!

Abstract of the research published in Neuron:

People find it easier to learn about topics that interest them, but little is known about the mechanisms by which intrinsic motivational states affect learning. We used functional magnetic resonance imaging to investigate how curiosity (intrinsic motivation to learn) influences memory. In both immediate and one-day-delayed memory tests, participants showed improved memory for information that they were curious about and for incidental material learned during states of high curiosity. Functional magnetic resonance imaging results revealed that activity in the midbrain and the nucleus accumbens was enhanced during states of high curiosity. Importantly, individual variability in curiosity-driven memory benefits for incidental material was supported by anticipatory activity in the midbrain and hippocampus and by functional connectivity between these regions. These findings suggest a link between the mechanisms supporting extrinsic reward motivation and intrinsic curiosity and highlight the importance of stimulating curiosity to create more effective learning experiences.
