- ZeitschriftenartikelInfluence of Identifier Length and Semantics on the Comprehensibility of Source Code(Softwaretechnik-Trends Band 36, Heft 3, 2016) Hofmeister, Johannes; Siegmund, Janet; Holt, Daniel V.Identifiers are essential for the understanding of source code. Programmers can name them arbitrarily, which is a major source for hard to understand code. We investigated how an identifier’s length and semantics affect program comprehensibility. In a controlled experiment, we showed that identifier names using proper words lead to a faster defect detection than identifier names using abbreviated words or single letters.
- KonferenzbeitragNeural Efficiency of Top-Down Program Comprehension(Software Engineering und Software Management 2018, 2018) Peitek, Norman; Siegmund, Janet; Parnin, Chris; Apel, Sven; Hofmeister, Johannes; Kästner, Christian; Begel, Andrew; Bethmann, Anja; Brechmann, AndréWe observed program comprehension with functional magnetic resonance imaging (fMRI) and found a difference in neural efficiency between top-down and bottom-up comprehension, but failed to find a significant effect from beacons. Furthermore, we were able to replicate the results of a previous fMRI study, thereby strengthening the role of fMRI as measurement technique to observe program comprehension and other related cognitive processes.
