In a recent study, Beeman and Kounios followed peopleâs gazes as they attempted to solve whatâs called the remote-associates test, in which the subject is given a series of words, like âpine,â âcrab,â and âsauce,â and has to think of a single word that can logically be paired with all of them. They wanted to see if the direction of a personâs eyes and her rate of blinking could shed light on her approach and on her likelihood of success. It turned out that if the subject looked directly at a word and focussed on itâthat is, blinked less frequently, signalling a higher degree of close attentionâshe was more likely to be thinking in an analytical, convergent fashion, going through possibilities that made sense and systematically discarding those that didnât. If she looked at âpine,â say, she might be thinking of words like âtree,â âcone,â and âneedle,â then testing each option to see if it fit with the other words. When the subject stopped looking at any specific word, either by moving her eyes or by blinking, she was more likely to think of broader, more abstract associations. That is a more insight-oriented approach. âYou need to learn not just to stare but to look outside your focus,â Beeman says. (The solution to this remote-associates test: âapple.â)
As it turns out, by simply following someoneâs eyes and measuring her blinks and fixation times (how long she looks at something before either looking away or closing her eyes), Beemanâs group can predict how someone will likely solve a problem and when she is nearing that solution. Although thatâs not an entirely new abilityâthe study replicates earlier work that relied on fMRI and EEG, which found similar patterns and showed that both the moment of insight and the preparatory phases are marked by distinct neural patterns, and it builds on a 2012 study of attention and verbal problem solvingâitâs a more easily observable and potentially trainable approach. âThis is less anatomical, but itâs more directly linked to attention,â Beeman says. âYour state of attention both before you get a problem and when youâre solving it matters.â
