Exceptions:

- Titles of video games

- Titles of surveys (unless this is the title of a book)

- Names of websites

Idem, ibidem, op. cit.

These are not used in APA style. Always use the Author (Year) and (Author, Year) formats.

Important Notes:

1. Each reference cited in text must appear in the reference list and vice-versa.

2. When citing two or more works together, arrange the in-text citations alphabetically in the same order in which they

appear in the reference list:

Past research (Gogel, 1990, 2006, in press) demonstrates that…

Recent research in developmental psychology has explored this issue (e.g., Bergstrom et al., 2006; Clément, 2010; Harris &

Corriveau, 2011; Harris & Koenig, 2006; Heyman, 2008; Heyman & Legare, in press; Koenig & Harris, 2005).

(Allern & Bale, 2012; Allern et al., 2019) [if the second author’s surname in the Allern et al. citation is after Bale]

(Allern et al., 2019; Allern & Bale, 2012) [if the second author’s surname in the Allern et al. citation is before Bale]

3. If you want to include several different citations in one set of brackets, they should be in alphabetical order, separated by a

semi-colon:

(Durie, 2003; McShane & Travaglione, 2007; Ministry of Education, 1996)

4. To cite more than one work by the same author(s), list the surname of the author(s) and then each different year of

publication, separated by a comma:

(Ministry of Education, 1996, 1999)

For groups of authors with the same lead author and different co-authors, also separate the citations with a comma, unless

they have the same year of publication:

According to previous research (see Whiteley et al., 2010, 2013) there is…

Styles can be combined:

(Durie, 2003; Ministry of Education, 1996, 1999; Whiteley et al., 2010)

5. Quoting two almost identical sets of authors with the same year of publication, spell out as many author names as

necessary in the in-text citation to tell them apart:

First citation in text:

(Marewski, Gaissmaier, & Gigerenzer, 2010)

(Marewski, Gaissmaier, Schooler, et al., 2010)

Subsequent citations in text:

(Marewski, Gaissmaier, & Gigerenzer, 2010)

(Marewski, Gaissmaier, Schooler, et al., 2010)

Notes: Only use “et al.” if there is more than one author missing from the in-text citation. List as many authors as necessary to

distinguish between references.

6. When citing a multi-volume work that has been published over the course of a number of years, use the date range as the

publication date in both the in-text citation and reference list:

In-text citation:

(World Health Organization, 2000–2006)

Entry in references list:

World Health Organization. (2000–2006). WHO annual report. Geneva: World Health Organization.

7. Citing different authors with the same surname, include the necessary initials after the surname in all in-text citations,

regardless of the year of publication:

(L.-J. Chen, 1993)

(Y. G. Chen, 2001)

(D. Jackson, 2018; M. C. Jackson et al., 2017)

Notes: Never include initials for subsequent authors in in-text citations. Entries in the final list of references are written

normally. Names in in-text citations must be organized according to the final list of references.

8. Citing different authors with the same surname and first name initial, include these authors’ full first names in the in-text

citations, regardless of the year of publication:

(Laura Green, 2009)

(Lorenzo Green, 2003)

(Leonard Green & Myerson, 2013)

Notes: Never include the full first name of subsequent authors in in-text citations. Names in in-text citations must be organized

according to the final list of references.

9. When making a general mention to a website (including, but not limited to, social media) it is not required that you include

an in-text citation and entry in the references list. Simply add the general URL:

News agencies like CNN provide breaking news coverage to millions of people every day on their website

(http://www.cnn.com) and Twitter account (http://twitter.com/CNN). In our first investigation, we analyzed the

content of CNN’s Twitter feed during the year 2012.

10. When quoting or summarizing a particular passage, include the specific page or paragraph number as well:

The painting was assumed to be by Matisse (Powell, 1989, Chapter 6), but later analysis showed it to be a forgery (Murphy,

1999, p. 85).

The patient wrote that she was unimpressed by the doctor’s bedside manner (Smith, 2006, para. 2)

11. You should italicize the name of a newspaper, magazine, or journal no matter where they appear in your manuscript, so

that it will always be The Economist, New York Times, etc., both in the text and reference list.

12. Use secondary sources sparingly, for instance, when the original work is out of print, unavailable through usual sources, or

not available in English. The words “as cited in” in the parenthetical reference indicate you have not read the original

research. Only include the secondary source in the reference list; the original work is merely cited in the text.

13. Always separate in-text citations from parenthetical text with commas around the year and never with squared brackets.

 structures (see Ellis et al. [2008] for recent meta-analyses).

✓ structures (see Ellis et al., 2008, for recent meta-analyses).

14. Use a shortened title (the first three words, or the full title if it is short) as the author in works without authors (e.g.,

newspaper articles ).

As discussed in “Economics nudging” (2017), governments…

(“All 33 Chile miners,” 2010)

15. An alternative to “et al.” in in-text citations is “and colleagues”, but this alternative can never been used in parenthetical

citations

Unpublished material

(phone calls, memos,

Do not include in the reference list

Important Notes:

Each reference cited in text must appear in the reference list and vice-versa.

Arrange entries in alphabetical order by the surname of the first author.

During, J. (2005).

Escalas, J. (2013).

Jacobus, M., Keller, E. F., & Shuttleworth, S. (Eds.). (2013).

Scott, A. J. (2012).

If authors have the same surname, alphabetize them according to their first initial.

Johnson, A. (2004).

Johnson, I. (2002).

If there are entries with identical authors, order them chronologically, earliest first.

Escalas, J. (n.d.).

Escalas, J. (2013).

Escalas, J. (2014).

Escalas, J. (in press).

If there are entries with identical authors published in the same year, organize them in the reference list alphabetically by the

title of the article or chapter. Then assign letter suffixes to the year (a, b, c, etc.).

Berndt, T. J. (1981a). Age…

Berndt, T. J. (1981b). Effects…

Johnson, I. (in press-a). Publishing…

Johnson, I. (in press-b). United…

If different entries begin with the same author, entries that have only that one author come before entries with more than

one author.

Johnson, I. (2004).

Johnson, I., & Chen, C. (2000).

If different entries begin with the same author, alphabetize by the second author. If the second author is the same, use the

third, and so forth.

Berndt, T. J., Keefe, K., & Smith, A. (1995).

Berndt, T. J., Sharp, C., Burley. K. (Eds.). (2000).

Berndt, T. J., Sharp, C., Garcia, A., & Burley. K. (2001).

Berndt, T. J., Zwitter, B. (2000).

Referencing works by two different authors with the same surname and first name initial, include their full first name in

square brackets after the initials in the references list. This is applicable to first authors only:

Do not use acronyms/abbreviations of organization that are authors in the final references list, use only the full version of the

name (exception: if in the text only the acronym is used, then use it as well in the final references list). There is always a full

stop at the end of the name of the organization.

European Association for International Education. (2014).

International Organization for Migration. (2018).

The capitalization of surnames beginning with a particle (e.g., de, d’, van, or von) depends on the origin of the name (usually,

Dutch names with lower case, Belgian/Flemish names with upper case). Always confirm in the author’s institutional page.

When having two or more works by the same author and year, for which in the references list the full date is provided (ex:

newspaper articles, Tweets, press releases,…) use the letters a,b,c,… to distinguish the different works. In the in-text citation

use only the year, do not add the month and day.
