Psychology Research Guide: Citing Sources in APA Style

Library resources for Psychology courses!

Why cite your sources?

Citing sources is an essential part of the writing process for several reasons:

  • Avoid Plagiarism!
  • Give proper credit to other author(s) whose ideas/research influenced your own.
  • Give your readers an opportunity to check out some of the authors that made your work so interesting!
  • Show your reader where your information came from and its' accuracy.
  • Get better grades!

What should you cite?

  • Facts, statistics, figures and other information that you are using and are not common knowledge.
  • Directly quoting someone else's words or ideas that appear in another publication.
  • Sources that need to be cited typically include: books, book chapters, journal articles, websites, audiovisual materials, dissertations, theses etc. 
  • If you are unsure, it's always safer to cite your source!

APA Citation

Welcome to APA Style

APA style was developed with the goal of implementing a set of guidelines for scientific writing, and is largely used in psychology, nursing, business and related fields. Very exciting!

We'll take a look at two important aspects of APA style:

In-text citations: The writer includes an abbreviated citation within the text of the paper.

Reference page: A more detailed citation list at the end of the paper that corresponds with the author's in-text citations.

 

 

APA Citation Examples

APA uses the Author-date system for in-text citations, below are some examples:

One Author:

The water in Pittsburgh, PA was shown to have dangerously high levels of lead from 2010-2018 (Smith, 2018).

Research by Smith (2018) proved that there was high levels of lead in the Pittsburgh, PA water supply from 2010-2018.

Two Authors:

Luzerne County's juvenile court system incarcerated a much higher percentage of juveniles than the PA statewide average (Gomez & Williams, 2019).

According to Gomez and Williams (2019), Luzerne County's juvenile court system incarcerated a much higher percentage of juveniles the PA statewide average.

Three or more authors:

Global warming will make Phoenix, AZ uninhabitable by 2050 (Johnson et al., 2016).

Johnson et al. (2016) proved that global warming will make Phoenix, AZ uninhabitable by 2050.

 

 

Let's take a look at some examples from an APA reference list:

Example book with one author:

Author Last Name, First Initial. (publication year).  Title of book.  Publisher.

Slotkin, R. (1973).  Regeneration through violence: The mythology of the American frontier, 1600-1860.  Wesleyn University Press.

Example book with two authors:

Albarelli, D. & Gennari, J. (2018).  Halloween: Celtic origins.  Carnegie Mellon University Press.

Example Journal article:

Author Last Name, First Initial. (publication year).  Title of article.  Journal Title, Volume #(Issue #), page #s. DOI

Mckelvey, K. (2019).  Silence is golden. Introvert Studies, 8(3), 200-207.  https://doi.org./10.1039/is0001234

Some notes:

**If the citation goes onto more than one line, all subsequent lines need a hanging indent.

**Include the DOI if the article has one.**

**If the article does not have a DOI, and has a working URL (not from a library/academic database), then include that.

**If the article is from an academic database (Ebsco, JSTOR etc.) and has a DOI then include it.  If it does not have a DOI then end the reference after the page numbers, don't include any database info.

Webpage from a website:

Author's Last Name, First Initial. (date of publication). Webpage title.  Website Title. URL

Hedges, C. (2019, December 15).  Hope lies in the streets. Truthdig. https://www.truthdig.com/articles/hope-lies-in-the-streets/

Some notes:  

**When citing a webpage, use as specific a date as possible.  This might just be the year, might be the year and month, or possibly the exact date.

**If the citation goes onto more than one line, all subsequent lines need a hanging indent.
