peer-reviewed papers available in three electronic
repositories. Analysis of the articles indicated that
sentiments indeed impact on software practices and
artifacts such as productivity, collaboration, and
source code. Evidence indicated to which extent pos-
itive and negative sentiments tend to impact software
practices and artifacts.
Considering that there are sentiments associated
with positive and negative polarity that were marked
as not specified in the selected studies regarding soft-
ware practices, there is still room for further inves-
tigation on the associated sentiments to the specific
impacts. Moreover, there is a tendency of a consider-
able set of open source software projects to have reg-
ular release cycles and to adopted the so called fre-
quent releases. We plan to investigate sentiments in
this context and to which extent they influence soft-
ware productivity. We also want to investigate how
programmers sentiments vary between releases.
