How to Cite References Containing Lead Authors With the Same Surname and Publication Date

Tyler

 

 

by Tyler Krupa

In a previous post, I provided guidelines on how to properly cite different groups of authors with the same lead author and publication date. As shown in that post, when you have two or more references of more than three surnames with the same year and they shorten to the same form (e.g., both Smith, Jones, Young, Brown, & Stanley, 2001, and Smith, Jones, Ward, Lee, & Stanley, 2001, shorten to Smith et al., 2001), you need to clarify which one you are citing each time. To do this, on the second and all subsequent citations, you should cite the surnames of the first two authors and of as many of the next authors as necessary to distinguish the two references, followed by a comma and et al. (see the sixth edition of the Publication Manual, p. 175).

Smith, Jones, Young, et al., 2001

Smith, Jones, Ward, et al., 2001

Now let’s add a twist and use references that contain different lead authors with the same surname and year of publication. Do you know what you should do differently? Let’s find out by looking at the following references:

Jones, B. T., Corbin, W., & Fromme, K. (2001). A review of expectancy theory and alcohol consumption. Addiction, 96, 57–72. http://dx.doi.org/10.1046/j.1360-0443.2001.961575.x

Jones, S. E., Oeltmann, J., Wilson, T. W., Brener, N. D., & Hill, C. V. (2001). Binge drinking among undergraduate college students in the United States: Implications for other substance use. Journal of American College Health, 50, 33–38. http://dx.doi.org/10.1080/07448480109595709

On the second and all subsequent citations, are you tempted to add the names of the additional authors to distinguish the two references? Although this seems like a logical way to proceed, because the lead authors are not the same person, you should instead include the lead author’s initials in all the text citations (for more information about when to use author initials for text citations, see my recent post). Therefore, the text cites for these two references would be as follows:

Correct:

First citation: Previous studies (e.g., B. T. Jones, Corbin, & Fromme, 2001; S. E. Jones, Oeltmann, Wilson, Brener, & Hill, 2001) have shown that . . .

Subsequent citations: Both B. T. Jones et al. (2001) and S. E. Jones et al. (2001) produced similar results . . .

Incorrect:

First citation: Previous studies (e.g., Jones, Corbin, & Fromme, 2001; Jones, Oeltmann, Wilson, Brener, & Hill, 2001) have shown that . . .

Subsequent citations: Both Jones, Corbin, and Fromme (2001) and Jones, Oeltmann, et al. (2001) produced similar results . . .

or

Subsequent citations: Both B. T. Jones, Corbin, and Fromme (2001) and S. E. Jones, Oeltmann, et al. (2001) produced similar results . . .

In these citations, because the lead authors are different, the lead author’s initials should be included in all text citations, regardless of how often they appear. In addition, there is no need to add the names of the additional authors to distinguish the two references on the second and subsequent citations because the initials before the surnames of the lead authors already accomplish that.

When to Use Author Initials for Text Citations

Tyler

 

 

by Tyler Krupa

You probably already know that references in APA Style are cited in text with an author–date system (e.g., Adams, 2012). But do you know how to proceed when a reference list includes publications by two or more different primary authors with the same surname? When this occurs, include the lead author’s initials in all text citations, even if the year of publication differs (see the sixth edition of the Publication Manual, p. 176). Including the initials helps the reader avoid confusion within the text and locate the entry in the reference list. For example, let’s look at the following two references and their corresponding text citations.

References

Campbell, A., Muncer, M., & Gorman, B. (1993). Sex and social representations of aggression: A communal-agentic analysis. Aggressive Behavior, 19, 125–135. http://dx.doi.org/10.1002/1098-2337(1993)19:2<125::AID-AB2480190205>3.0.CO;2-1

Campbell, W. K., Bush, C. P., & Brunell, A. B. (2005). Understanding the social costs of narcissism: The case of the tragedy of the commons. Personality and Social Psychology Bulletin, 31, 1358–1368. http://dx.doi.org/10.1177/0146167205274855

Text Citations

First citation: Many studies (A. Campbell, Muncer, & Gorman, 1993; W. K. Campbell, Bush, & Brunell, 2005) have shown . . . .

Subsequent citations: Both A. Campbell et al. (1993) and W. K. Campbell et al. (2005) provided participants with . . . .

As you can see from the examples above, even though the year of publication differs in the two Campbell references, the lead author’s initials should be included in all text citations, regardless of how often they appear.

Although this rule seems straightforward, one thing that trips up some writers is how to proceed when different lead authors with the same surname are also listed in other references in which they are not the lead author. To help illustrate what should you do, let’s look at the earlier Campbell examples again, but now let’s add some additional references.

References

Brown, Y., & Campbell, W. K. (2004).

Campbell, A., Muncer, M., & Gorman, B. (1993).

Campbell, W. K., Bush, C. P., & Brunell, A. B. (2005).

Smith, L. N., Campbell, A., & Adams, K. (1992).

Although you may be tempted to include the initials every time the surname Campbell appears in the text citations, note that per APA Style, the initials should be included only when Campbell is the lead author. Therefore, initials should be used for only two of the above four references in the text citations.

Text Citations

First citation: Many studies (Brown & Campbell, 2004; A. Campbell, Muncer, & Gorman, 1993; W. K. Campbell, Bush, & Brunell, 2005; Smith, Campbell, & Adams, 1992) have shown that . . .

Subsequent citations: . . . as was done in previous studies (Brown & Campbell, 2004; A. Campbell et al., 1993; W. K. Campbell et al., 2005; Smith et al., 1992).

Another related item to note is that if the reference list includes different lead authors who share the same surname and first initial, you should provide the authors’ full first names in brackets (see the Publication Manual, p. 184).

References

Janet, P. [Paul]. (1876).

Janet, P. [Pierre]. (1906).

Text Citations

(Paul Janet, 1876; Pierre Janet, 1906)

Accentuate the Appositive

Daisiesby Stefanie

Rose is a rose is a rose is a rose. —Gertrude Stein, “Sacred Emily”


One of the delights of life is that there is usually more than one way to describe something, and often those details matter. I may walk into a room and see a rose, a dog, and a book (I admit, my house is very messy). But that rose is of the Claude Monet variety, grown in my neighbor’s tucked-away garden. That dog is a tricolor beagle that never barks. That book with the oddly literal title is the fifth and final novel of a supernatural mystery series. The details of these items are what differentiate them from the other roses, dogs, and books that might be in the same vicinity (like I said, my house is messy).
 
An appositive is a restatement of what a thing is, in different terms, that adds to the understanding of that thing’s identity. The appositive can be short or long, restrictive or nonrestrictive; an appositive appears next to the noun it is renaming.
 
Appositives are usually set off by commas. That is, they are usually of the nonrestrictive variety, in that they provide extra information but the sentence is clear and complete even without them. By “set off,” I mean that when a nonrestrictive clause appears in the middle of a sentence, commas go both before and after the appositive (see also section 3.22 of the Publication Manual of the American Psychological Association, 6th ed., p. 83, for additional examples).

The flower, a carefully cultivated and locally grown Claude Monet rose, drew the eye of my visitor.

My faithful dog, a tricolor beagle whose main claim to fame is his complete failure as a watchdog, didn’t even stir when the stranger entered the room.

The visitor touched the cover of the book on the end table, Blood Debt by Tanya Huff.

Restrictive appositives are essential for meaning and do not take commas (see section 4.03 of the Publication Manual, p. 89). Note in the examples below that because the narrator has more than one brother and because there is more than one blockbuster movie, the specific names offered in the appositives are necessary and thus should not be cordoned off with commas.

My brother John is much more reasonable than my brothers Paul and George.

The blockbuster movie Independence Day was blaring at a ridiculous volume from the other room.

Using appositives well can add detail and life to your writing. If you have comments or questions about appositives, please write to styleexpert@apa.org or leave a comment below!

How to Cite a Data Set in APA Style

Timothy McAdooby Timothy McAdoo

Whether you’re a "numbers person" or not, if you’re a psychology student or an early-career psychologist, you may find yourself doing some data mining.  Psychologists are increasingly encouraged to provide their data online for other researchers to use and analyze.  And big-data psychologist is one of the hot new jobs in the industry.

Because big data is a big deal, you’ll want to know how to cite a data set.

Reference Example

U.S. Department of Health and Human Services, Substance Abuse and Mental
    Health Services Administration, Office of Applied Studies. (2013). Treatment
    episode data set -- discharges (TEDS-D) -- concatenated, 2006 to 2009
[Data
    set]. doi:10.3886/ICPSR30122.v2

Because this data set has a DOI, the reference includes that DOI. For data sets without a DOI, the URL should be included in the reference, like this: "Retrieved from http://www.icpsr.umich.edu/SDA/SAMHDA/30122-0001/CODEBOOK/conc.htm"

Also note that the name of the data set is italicized. And, a description of the material is included in brackets after the title, but before the ending period, for maximum clarity.

big dataIn-Text Citation Example

The in-text citation for this reference would be "U.S. Department of Health and Human Services, Substance Abuse and Mental Health Services Administration, Office of Applied Studies (2013)" or "(U.S. Department of Health and Human Services, Substance Abuse and Mental Health Services Administration, Office of Applied Studies, 2013)."  Of course, if you cite that a number of times, you’ll probably want to abbreviate the author name.

Related Documents

Data sets sometimes have many other documents associated with them (e.g., reports, papers, and analyses about the data; tests and measures used to procure the data; user manuals; code books). When you are citing one of these related items, whether instead of or in addition to the data, be sure to describe the format in brackets after the title. For example, in this example from the APA Style Guide to Electronic References, Sixth Edition, "Data file and code book" is used to describe the format:

Pew Hispanic Center. (2004). Changing channels and crisscrossing cultures:
    A survey of Latinos on the news media
[Data file and code book]. Retrieved
    from http://pewhispanic.org/datasets/

The in-text citation would be "Pew Hispanic Center (2004)" or "(Pew Hispanic Center, 2004)."

For more about big data, you may be interested in these pages on the APA website:

Note: I modified this post on 12/23/2013 to include the DOI of the data set in the first reference example.

The First Thanksgiving: A Tale of Common Knowledge

Vintage-thanksgiving-clip-art-turkey-in-top-hat-with-restaurant-menus by The APA Style Radio Theatre

 

(Crowd noises, conversation, chairs squeaking, gradually give way to the sound of a gavel)

CHAIR: Ladies and gentlemen. . . . Settle down, if you please. Thank you. I hereby call to order the Autumn Assembly of the North American Society of Professional Nitpickers. On behalf of the entire group, I’d like to offer our appreciation to the Catering Committee for the delightful holiday repast we’ve just enjoyed. The turkey was roasted to a turn, the pies were superb, and the wine pairings were expertly chosen (aside from the sauterne and sauerkraut, but I shall not quibble with this fine Baltimore tradition).

In our refreshed state, let us now turn to the business at hand: establishing the core content of common knowledge about Thanksgiving. Now, as we all know, the first Thanksgiving was celebrated in Massachusetts in 1621. . . .

(Commotion)

CHAIR: Order! Order! (gavel) The chair recognizes the delegate from Virginia.

VIRGINIA: Without wishing to be disagreeable in any way, I must respectfully contradict that statement. It’s common knowledge in Virginia that the first Thanksgiving was celebrated at Berkeley Hundred on December 4, 1619—a full year before the arrival of the Pilgrims in the New World.

MASSACHUSETTS: Oh, not this again! Sure, a boat load of people landed in Virginia and declared a “yearly and perpetual day of thanksgiving to Almighty God.” But everybody knows the first Thanksgiving was celebrated in Plymouth Colony in 1621. It’s on TV every year—the Peanuts special, the Macy’s Thanksgiving Day Parade. You ever see anybody dressed up on a float as Captain John Woodleaf? No! It’s Miles Standish!

VIRGINIA: Apparently the honorable delegate from Massachusetts is unable to do the math—or the history, if he considers a cartoon to be a valid source of historical data on the Plymouth parvenus.

(Angry shouts of “Who you calling a parvenu?” etc., are interrupted by the sound of a pistol shot fired in the air.)

TEXAS: Glad I got your attention, ’cause I can settle this right now. The first Thanksgiving was celebrated in El Paso, Texas, by feller named Juan de Oñate. April 30, 1598. Write that down, boys, it’s official. Common knowledge, you might say.

FLORIDA: If we’re going to count non-English settlers, what about my Huguenots? They celebrated a day of thanksgiving in June 1564 for their safe escape from France. It was right near Jacksonville.

MASSACHUSETTS: Yeah, OK, they could be contenders. But where are they now?

FLORIDA: They were all slaughtered by Admiral Menéndez in 1565.

(Silence)

ILLINOIS: Forget this colonial stuff. We celebrate Thanksgiving today because of the federal holiday, which was started in 1863 by Abe Lincoln.

VIRGINIA: George Washington did it first.

NEW YORK: And FDR did it last!

(Hubbub)

CANADA: Can I just point out that no one is addressing the real problem, which is that you’re all celebrating Thanksgiving in the wrong month. Now in Canada, we . . .

(Cries of “Sit down!”, “So?”, and “But you’re Canada!” drown out the rest of his speech.)

CHAIR: Ladies and gentlemen, there has been sufficient discussion. Let us proceed to the Showing of the References.

(Paper rustles as each delegate produces a list of references to substantiate his or her point.)

CHAIR: From the Showing of the References, it is clear that each of you has a well-supported claim to be representing common knowledge about the first Thanksgiving. Your information is factual, not mere opinion; it is well-established in the community in which it is used; and it is supported by evidence. These are the three criteria for common knowledge, and you have met them. I move that we adjourn to the bar for football. All in favor say “Aye.”

CHORUS: Aye!

CHAIR: The motion carries. Happy Thanksgiving, everyone!

Thanksgiving-Chef-VintageGraphicsFairy1
Moral:
Facts that are common knowledge in one setting may need to be backed up by citations in another. Common knowledge is not an opinion (“Tamales are better than turkey”) but a fact (“Thanksgiving is always on Thursday”).

Pluralize Numbers and Abbreviations Without Apostrophes

DB2



by David Becker

A common mistake people make is to include apostrophes when pluralizing a number or an abbreviation. Apostrophes are generally used in contractions and to indicate the possessive case, but they are not used to form plurals of numbers and abbreviations in APA Style.

For instance, writing “the 1960’s” when referring to that entire decade is incorrect; instead, one should write “the 1960s.” The same rule applies to the plural form of any other type of number, such as describing someone’s age (e.g. “clients in their 80s”), and is discussed further in section 4.38 on page 114 of the Publication Manual.

A similar rule in section 4.29 on page 110 applies to abbreviations. Just as with numbers, don’t include an apostrophe when pluralizing abbreviations. For example, when pluralizing an acronym, such as “CV” for “curriculum vitae,” all you need to do is add an s to the end, as in “CVs.” This rule also applies to standalone letters, as in “The students all received As.” For abbreviations that end with a period, such as “Ed.” to indicate an editor in a reference list entry, add an s before the period, as in “Eds.” When pluralizing an italicized abbreviation, remember not to italicize the s, as in “ps.” Just don’t add an apostrophe.

For more information, take a look at our other posts on punctuation in APA Style. Punctuation is also covered in more detail on pages 87–96 of the Publication Manual. And, of course, please feel free to comment on this post or contact us with any of your style questions.

Is It Sometimes Okay to Begin a Sentence With a Lowercase Letter?

Tyler

 

 

by Tyler Krupa

A basic grammar rule is that the first word in a complete sentence should be capitalized. But do you know how to proceed when a name that begins with a lowercase letter begins a sentence? Or whether it is okay to begin a sentence with a lowercase statistical term (e.g., t test or p value)?

Although the two examples listed above seem to be exceptions to the rule that the first word in a sentence should be capitalized, this is not the case. Note that per APA Style, the first word in a complete sentence should always be capitalized.

So what should you do when you come across the above examples in your writing? Getting it right is simple as long as you remember the following two guidelines (see sections 4.14 and 4.30 in the sixth edition of the Publication Manual):

1. If a name that begins with a lowercase letter begins a sentence, then it should be capitalized.

2. Do not begin a sentence with a lowercase statistical term (e.g., t test or p value), a lowercase abbreviation (e.g., lb), or a symbol that stands alone (e.g., α).

To help illustrate the first guideline, let’s look at the following example:

Correct:

Van Morrison and Smith (2012) interviewed 100 participants . . .

Incorrect:

van Morrison and Smith (2012) interviewed 100 participants . . .

In the example above, even though the usual presentation of the surname van Morrison begins with a lowercase v, it is correct to capitalize the first letter of the surname when the name begins a sentence. However, note that if the surname van Morrison is used later in the sentence or in references/citations, then the lowercase v is retained (e.g., At the conclusion of the participant interviews, van Morrison and Smith . . .). For more information on how to correctly capitalize author names, see the following post to our blog.

Now let’s look at an example that illustrates the second guideline:

Correct:

We used t tests to determine . . .

Incorrect:

t tests were used to determine . . .

Incorrect:

t Tests were used to determine . . .

Incorrect:

T tests were used to determine . . .

Note that in the example above, it is not okay to capitalize the statistical term at the beginning of the sentence because doing so changes the meaning of the statistic. Therefore, in instances such as these, it is necessary to recast the sentence. However, note that it is okay to begin a sentence with a capitalized statistical term (e.g., F tests indicated that . . .). For more information on how to format statistics in your paper, see the following post to our blog.

We hope these examples clear up this point of possible uncertainty. Still have questions? Leave us a comment.

Comma Usage and Compound Predicates

DB2





by David Becker

Time for a brief review of Grammar 101! As you know, a sentence has two major components—the subject and the predicate. The subject is the person, place, or thing that the sentence is about. The predicate says something about the subject. Here is a basic example with the subject in blue and the predicate in red:

Ritija scratched the cat’s head.

A compound predicate says two or more things about the subject. A common mistake people make is to insert a comma between two elements of a compound predicate. This comma adds a pause that creates distance between the subject and the predicate, so you should not include a comma in this case, just as you would not use a comma to separate a verb from its subject or object. Here is an example that demonstrates the correct and incorrect ways to write a sentence with a compound predicate:

Correct: Ritija scratched the cat’s head and rubbed his belly.
Incorrect: Ritija scratched the cat’s head, and rubbed his belly.

However, a compound predicate with three or more elements constitutes a list, so it would be correct to separate them with commas. Commas are essential in this case to distinguish one element of the compound predicate from the rest. (Don’t forget the serial comma!)

The cat closed his eyes, purred, and twitched his ears.

Also note that a sentence with a compound predicate is different from a sentence with two independent clauses joined by a conjunction. The latter requires a comma to create a pause between two distinct thoughts that could be separate sentences. Here’s an example:

Correct: Ritija scratched the cat’s head, and the cat purred.
Incorrect: Ritija scratched the cat’s head and the cat purred.

I hope this will help you avoid incorrect comma usage in the future. For more information on when and when not to use commas, see section 4.03, pages 88–89 of the Publication Manual. If you have any other questions, feel free to contact us or comment on this post.
