APA Style uses sentence-style capitalization for article titles in the reference list, which means only the first word and any proper nouns are capitalized (e.g., “Language production and serial order”).
Sentence-style capitalization is also used for book and webpage titles.
However, for the titles of journals, headline-style capitalization is used. This means all words except prepositions, conjunctions, and articles are capitalized (e.g., Journal of Communications Technology and Electronics).
