In Equation 6, c₂ should have been s₂. 

In the Materials and Methods, in the first paragraph below the “Experimental details” section, the seventh sentence originally read: 

“To create the splashes, we sampled five dots from a Gaussian distribution centered on the hidden coin's location using distributions with two different standard deviations (2.24% of the screen width and 8% of the screen width).” 

It should read: 

“To create the splashes, we sampled four dots from a Gaussian distribution centered on the hidden coin's location using distributions with two different standard deviations (2.5% of the screen width and 10% of the screen width).” 

All of the modeling and subsequent data analysis used the correct values, and the conclusions are unaffected by this change. 

The online article has been updated to reflect the changes.
