The 82-year-old poem was resurrected as a meme, with Twitter users rewriting lines centering around the central image of plums in an icebox to strange ends. A new study from NYU in the journal Psychology of Aesthetics, Creativity, and the Arts aims to untangle, through the lens of psychology, what makes different poems appealing. And, the researchers claim, a lot of it comes down to imagery (not just plums).

The NYU team tapped 402 users on Amazon’s Mechanical Turk, a sometimes-controversial automated service that social psychologists use to gather large amounts of data. Participants in one group were made to read a few more than 30 haiku, while those in another group read 16 sonnets. Afterwards, they answered questions about the vividness of the poems’ imagery and how much they enjoyed the poems or found them aesthetically pleasing. “Across both poem genres,” the authors write “we found that vividness was the best predictor of aesthetic appeal.” Book specialist Charlotte Riordan holds a magnifying glass over a 450-year-old letter written by Mary Queen of Scots. David Moir/Reuters The memeifcation of poetry probably has more to do with the marriage of Twitter, a form that encourages brevity, and equally short poems like This Is Just to Say. Studying literature through the lens of psychology can also be tricky business. People’s experience reading a poem can be far more complex than, say, measuring a person's reaction to an electric shock. A widely publicized 2013 study in the journal Science, for example, purportedly showed that reading “literary fiction” made people better at reading emotional states. It got a lot of press, but independent researchers were unable to replicate the findings in a followup study. The two studies
