Computer Code as a Medium for Human Communication: Are Programming Languages Improving?
Programming languages are not only useful to command computers, they also increasingly are a medium for human communication. The authors will use the framework of distributed cognition to discuss how knowledge is shared in a team of programmers and to show that computer code plays an important role in it. The resulting model of how programmers comprehend code suggests that common grounds play an important role in it. He proposes two hypotheses concerning the means used by programmers to refer to common grounds from within their code. The hypotheses imply that modern languages, such as Scala, offer advantages as human communication mediums. He describes an experiment, using an eye-tracking device, which measures the performance of code comprehension.
