I think the citation style depends on the journal that will publish your research article. My institution adopts the APA style and most of the journals I publish with use same.
The APA (American Psychological Association) Style is commonly used for social and behavioural sciences such as psychology, sociology, and education. The Modern Language Association developed the MLA Style for language and literature. I prefer to use the Name-Year system as recommended by the Council of Science Editors (CSE Style).
