I cannot access the study, but I find it odd that they say in abstract: > Results indicate that camel casing leads to higher accuracy among all subjects regardless of training, and those trained in camel casing are able to recognize identifiers in the camel case style faster than identifiers in the underscore style. What does it mean: > those trained in camel casing are able to recognize identifiers in the camel case style faster than identifiers in the underscore style. It is not normal if you train in reading something => you are good in recognizing that things that you are trained than something else than you did not train for? If anyone has access to the study, how many among 135 are programmers that were trained in camel case and how many in snake case?
