Use a narrative citation when the author's name is part of your sentence:

• Nadeau (2012) stated that chocolate is delicious.

• According to Nadeau (2012), chocolate is delicious.

Use a parenthetical citation to cite information that does not belong in the sentence grammatically:

• Chocolate is, in fact, delicious (Nadeau, 2012).

• As one author argued, "chocolate is delicious" (Nadeau, 2012, p. 1).
