Note: Your in-text citation, if you are referring to this figure in other parts of your paper, would simply be (see Figure 1) and your reference list will include the source, which would be S. Sternberg's article in this case, if we use the example above.
If you are reading about an interview conducted by someone else found in a particular resource, you should choose the reference format most suitable appropriate for the source. For e.g. If you read the interview in a magazine, you might want to cite it like an article from an online magazine (see examples in Periodicals (Articles) tab).
The example below is cited like a web document found on a particular website, with the qualifier [Transcript] to indicate the material type. The date element is the date the transcript was created or made available. If no date is known, use (n.d.).
