Most brain-imaging studies make 3 questionable assumptions: mental events are localizable, map uniquely to dedicated #brain circuitry, & are independent of larger context. These 19th-century views need an update. New #OpenAccess paper in @TrendsCognSci. 1/ cell.com/trends/cogniti…
Better assumptions: (1) Mental events comprise distributed activity across the whole brain; (2) Brain & behavior are linked by degenerate, many-to-one mappings; (3) Mental events emerge as a complex ensemble of non-linear, interacting signals from brain, body, & outside world. 2/
Our lab's new paper in @NatureComms examines how famous actors portray emotion with their faces. The findings have important implications for so-called "Emotion AI" systems. I'll summarize our novel method and findings. @AffectiveSciLab 1/13 news.northeastern.edu/2021/08/20/you…
Summary: Famous actors who portray emotion convincingly don't conform to stereotypes (e.g. scowling for anger, pouting for sadness). Rather, variety is the norm. Also, viewers didn't reliably identify the portrayed emotion from the actor's face alone, without context. 2/13
Our study used photos of 100+ of famous, award-winning actors as they portrayed emotional scenarios with their faces: Patrick Stewart, Allison Janney, Peter Dinklage, Amy Poehler, Ellen Burstyn, Don Cheadle, Elliot Gould, Robin Wright, Martin Landau, Danny Glover & more. 3/13
