Study: smartphone game shows baggage screeners likely to miss ultra-rare items
Wired: A study has used data collected from a smartphone game that allows users to act as airport baggage screeners to prove that ultra-rare items are highly susceptible to search errors. Cognitive psychologists from Duke University in North Carolina analysed data collected from a game called Airport Scanner, which was developed by Kedlin Company and tests gamers' visual scanning skills. Overall the team studied 20 million virtual suitcase search results collected between December 2012 and March 2013 and discovered that in the majority of cases, participants failed to identify objects which only occurred rarely.

The Secret of Comedy Really Is Timing
Pacific Standard: Did you hear the one about Hurricane Sandy? Did you find it hilarious? Tasteless? Or just lame?

An analysis of responses to humorous quips referencing last year’s devastating storm suggests the adage that “comedy equals tragedy plus time” needs to be modified.

Adventures in Experimenting On Toddlers
The Wall Street Journal: The Gopnik lab is rejoicing. My student Caren Walker and I have just published a paper in the well known journal Psychological Science. Usually when I write about scientific papers here, they sound neat and tidy. But since this was our own experiment, I can tell you the messy inside story too. First, the study—and a small IQ test for you. Suppose you see an experimenter put two orange blocks on a machine, and it lights up. She then puts a green one and a blue one on the same machine, but nothing happens. Two red ones work, a black and white combination doesn't. Now you have to make the machine light up yourself.
