within a given module. Recently, conceptual cohesion metrics have been proposed for computing cohesion based on the responsibilities a given module realizes. Besides different flavors of cohesion, there is a lack of empirical evidence about how developers actually perceive cohesion and what kind of cohesion measurement aligns with developers’ perception. In this paper we fill this gap by empirically investigating developers opinion through a web-based survey, which involved 80 participants from 9 countries with different levels of programming experience. We found that: most of the developers are familiar with cohesion; and they perceive cohesion based on class responsibilities, thus associating more with conceptual cohesion measurement. These results support the claim that conceptual cohesion seems to be more intuitive and closer to the human-oriented view of software cohesion. Moreover, the results showed that conceptual cohesion measurement captures the developers’ notion of cohesion better than traditional structural cohesion measurement.
