When you use someone else's words or ideas in your papers, you should create In-text citations (within the paper) and References list citations (at the end of the paper). Each In-text citation should lead to a References list citation, and each References list citation should come from an In-text citation.
Use the Publication manual of the American Psychological Association (7th ed.) to correctly cite your sources and format your research papers.
