Cognitive-Driven Development (CDD) is a coding design technique that aims to reduce the cognitive effort that developers place in understanding a given code unit (e.g., a class). By following CDD design practices, it is expected that the coding units to be smaller, and, thus, easier to maintain and evolve. However, it is so far unknown whether these smaller code units that are designed through CDD are also easier to understand. In this work we aim to assess to what extent CDD improves code readability. To achieve this goal, we perform a survey answered by 102 professional software engineers. In the survey, we offer the participants our notion of readability and asked them to vote on which code fragment is more readable. Overall we observed that CDD improves code readability, but to some extent.
