AA = Avoid Anthropomorphism

Do not assign uniquely human qualities to inanimate objects. For instance, results do not think and the literature does not believe. Inanimate objects or concepts can perform actions, such as supporting theories, demonstrating effects, and so forth, but they cannot engage in {\em strictly} human activities such as thinking and believing.

See Section 2.04 (Precision and Clarity - Attribution), p. 39 of the APA Publication Manual for further details.

A/O = Avoid And/Or Constructions

Avoid ``and/or'' constructions because they are awkward to read, even though the usage of this construction is quite common in informal writing. The conjunction or is inherently inclusive when used by itself. To indicate an exclusive or, we need to pair with the word either, and we can amplify the exclusivity by including the phrase but not both.

Wrong:The participants reported using alcohol and/or tabacco within the previous week.
Right (inclusive or):The participants reported using alcohol or tabacco within the previous week.
Also Right (inclusive or):The participants reported using alcohol, tabacco, or both within the previous week.
Also Right (exclusive or):The participants reported using either alcohol or tabacco within the previous week.
Also Right (exclusive or):The participants reported using either alcohol or tabacco (but not both) within the previous week.

AWO = Awkward Word Order

Clear writing depends on a logical word order; placing words in an awkward order can obscure the meaning entirely or confuse the reader. The word reordering symbol, , may have been used to suggest an alternative word order. A frequent mistake is to place an interruptive word, such as however at the beginning of a sentence (or worse yet, a paragraph) when there are no continuing ideas to interrupt.

The APA Publication Manual does not provide further details.

BL = Biased Language

It is very important to make sure that our language is unbiased. We need to avoid equating people with their age, gender, race, ethnicity, or sexual orientation. We must (a) describe at the appropriate level of specificity, (b) be sensitive to labels, and (c) acknowledge participation.

One of the most common mistakes is using male and female as nouns, when they should only be used as adjectives. Since male and female can refer to the gender of any living entity, they can be seen as equating people with their gender. The terms, men and women, however, cannot apply to non-human entities and avoid this problem. Additionally, the term homosexuals equates people with their sexual orientation. Although unwieldy, this group of people should be referred to as lesbians, gay men, and bisexual people. Also keep in mind that homosexuality refers to a sexual orientation and not to any specific behavior. There is no such thing as "homosexual behavior."

See Section 2.12 (Linguistic Devices - Guidelines to Reduce Bias in Language), pp. 61-76 of the APA Publication Manual for further details.

CS = Comma Splice

A comma splice occurs when a comma has been used incorrectly in an attempt to splice two ideas together. Usually, this error occurs when two independent clauses have been joined with a comma, rather than (a) a comma and a coordinating conjunction, (b) a semi-colon, or (c) a semi-colon and a coordinating conjunction. A comma alone is not strong enough to hold two independent clauses together.

Wrong:The participants were shown to a workstation, they were then instructed to read and sign the consent form.
Right:The participants were shown to a workstation, and they were then instructed to read and sign the consent form.
Also Right:The participants were shown to a workstation; they were then instructed to read and sign the consent form.
Also Right:The participants were shown to a workstation then were instructed to read and sign the consent form.

Note that the first correct example uses the simple comma and coordinating conjunction option. Although the second correct example uses the semi-colon option, it isn't really necessary in this particular example because commas are not used elsewhere. If the sentence contained one or more dependent clauses set off from the rest of the sentence with commas, then the semi-colon must be used to give greater clarity by signaling the reader that this conjunction is a major one (i.e., of two independent clauses).In the third alternative, the sentence has been rewritten to have a compound verb, eliminating the second independent clause altogether. The sentence also could have been rewritten to change one of the independent clauses into a dependent clause.

IPP = Imprecise use of a Personal (or impersonal) Pronoun

Only personal pronouns should be used to refer to people. Using the pronoun it to refer to a person is as creepy as using the relative pronoun that to refer to people.

Wrong:The participants that were assigned to the control group were taken to a separate room.
Right:The participants who were assigned to the control group were taken to a separate room.

IRP = Imprecise Use of a Relative Pronoun

The relative pronoun which is used with nonrestrictive clauses (clauses that do not change the meaning of the sentence), and the relative pronoun that is used with restrictive clauses (clauses that do change the meaning of the sentence). Also, keep in mind that restrictive clauses must not be separated from the rest of the sentence by commas, and non-restrictive clauses must be set off by commas. To use which and that precisely, first decide if the clause is restrictive or non-restrictive; if the former, use that and no commas; and if the latter, use which and commas. You can never correctly use that with commas or which without commas!

Wrong:The debriefing form, that was printed on letterhead, was provided after the session was concluded.
Also Wrong:The debriefing form which was printed on letterhead was provided after the session was concluded.
Right:The debriefing form that was printed on letterhead was provided after the session was concluded.
Also Right:The debriefing form, which was printed on letterhead, was provided after the session was concluded.

Note that in the two wrong examples, we cannot tell if the author intended for the detail about letterhead to change the meaning of the sentence if it were left out. In the first correct example, the author clearly intended for the reader to consider the letterhead paper to be so important that the meaning of the sentence would change if it had been eliminated. In the second correct example, the author clearly intended for the reader to consider the letterhead paper to be a secondary and less important matter. It is important to follow the rules outlined here about the precise use of which and that (with appropriate commas) to signal the reader whether the clause is restrictive or non-restrictive. These rules apply even when several clauses in a row use the same relative pronoun.

See Section 2.10 (Relative Pronouns and Subordinate Conjunctions - Pronouns), p. 55 of the APA Publication Manual for further details.

IS = Incomplete Sentence

All sentences must have a subject and a verb. This problem can be more frequent when the subject is a complex phrase, rather than a simple noun, especially when the verb is a state of being rather than an action.

Wrong:Trying to avoid the confusion of not having both a verb and a subject, especially in sentences with complex subjects, such as this one.
Right:Trying to avoid the confusion of not having both a verb and a subject, especially in sentences with complex subjects, such as this one, can be frustrating.

If you run into this error, print a draft of your work, circle each subject, and underline each verb. You may also find it helpful to think of a "reduced" version of the sentence with just the subject and verb, such as "Trying to avoid confusion can be frustrating." The subject and verb are much more obvious in this sentence than the example. Although this reduced form does not express the idea well, thinking about it can help you make sure to include both a subject and a verb in the more complex sentence.

There is no further detail in the APA Publication Manual because it is assumed that anyone writing in APA format should already know how to write in complete sentences.

ISC = Imprecise Use of a Subordinating Conjunction

It is important in scientific writing to use subordinate conjunctions (i.e., while, since, although, because, whereas) precisely. The first two examples, while and since, are particularly problematic because sometimes they imply temporal relationships, and sometimes they do not. Your writing will be clearer if while is reserved for linking actions that take place at the same time. Similarly, using since to link one event that follows another in time rather than to indicate a causal relationship will add clarity to your writing. Causal linkages can better be described using the subordinating conjunction because.

Wrong:While the data in Reeder and Pryor's (1992) first study were collected from undergraduates, their 1995 study used data collected from the community at large.
Right:Although the data in Reeder and Pryor's (1992) first study were collected from undergraduates, their 1995 study used data collected from the community at large.
Also Right:Whereas the data in Reeder and Pryor's (1992) first study were collected from undergraduates, their 1995 study used data collected from the community at large.

We note that it is actually highly unlikely that the data for the two studies were being collected at the same time, which is one valid interpretation of the incorrect wording.

NIC = Not an Independent Clause

When a coordinating conjunction is preceded by a comma that is not being used to punctuate a list, the comma and coordinating conjunction should indicate the beginning of an independent clause. If there is no such independent clause, then the comma must be removed.

Wrong: Prior to conducting the main analysis, the data were screened for outliers, and cases with large numbers of missing data points.
Right: Prior to conducting the main analysis, the data were screened for outliers and cases with large numbers of missing data points.

Including the comma as in the incorrect example leads the reader to expect an independent clause. When the reader gets to the period without having found a verb for what was thought to be an independent clause, the reader has to go back and try to figure out why the comma is there. The answer, of course, is that there is no reason for the comma to be there. Keep in mind that a compound verb, subject, or object with only two components will not need a comma to separate them.

See Section 3.02 (Comma), pp. 79-80 of the APA Publication Manual for further details.

NPA = Noun-Pronoun Agreement

Pronouns must agree with the nouns to which they refer in both gender and number. Singular nouns take singular pronouns; plural nouns must take plural pronouns; and gender-neutral nouns must take gender-neutral pronouns.

Wrong:Each participant was asked to provide their informed consent.
Right:Each participant was asked to provide his or her informed consent.

NVA = Noun-Verb Agreement

The subject and verb must agree in number: Plural subjects must be paired with plural verbs, and singular subjects must be paired with singular verbs. Very often, the confusion stems from intervening phrases or clauses between the subject and verb.

Wrong:The proportion of variance accounted for by the main effects were significant at the .05 level.
Right:The proportion of variance accounted for by the main effects was significant at the .05 level.

The plural word effects may be distracting and lead the writer to use the plural verb form even though the subject of the sentence is proportion, which is singular.

Note that the word data is always a plural word! The singular form of data is datum. Further, data is always plural in context.

See Section 2.07 (Agreement of Subject and Verb), pp. 44-47 of the APA Publication Manual for further details.

ROS = Run-on Sentence

A run-on sentence is one that contains too many independent clauses. These sentences may occur because the independent clauses are improperly punctuated or when there are simply too many ideas in the same sentence.

Wrong:The experimenter read the instructions aloud and the participants read and signed an informed consent form.

SI = Split Infinitive

It is important that the two elements of an infinitive are not split by any words, despite whether or not it "sounds right!" Adverbs, adjectives, and other modifiers simply cannot be placed inside an infinitive.

Wrong:The researcher used Tukey's HSD for post-hoc testing to further explore the differences between the cells of the ANOVA design.
Right:The researcher used Tukey's HSD for post-hoc testing to explore further the differences between the cells of the ANOVA design.

We frequently split infinitives in our spoken language, so often such phrases sound right, whereas the correctly worded phrasing sounds stiff and formal. We might or might not catch split infinitives in our spoken language, but they are very noticeable in written language.

SRC = Seriation Requires Commas

When there are three or more elements in a list, all elements must be separated from the others with a comma, and the last two elements must be separated from each other with a comma and a coordinating conjunction.. Although this last comma is optional in non-technical writing (you don't usually see it in novels, for instance), it is not optional in technical writing.

UPV = Unnecessary Passive Voice

It is important to avoid the passive voice when the subject is known. Only in very rare situations is the verb to be so heavily emphasized and the subject de-emphasized, in which case passive voice is okay. Also, if the subject of the action is unknown, then passive voice is okay.

= Paragraph Break Error

Add a paragraph break where indicated by the symbol because the main topic or central idea has shifted. Each paragraph should have only one major theme, and very long paragraphs with multiple themes should be avoided. If the symbol is preceded by the word no or has a line drawn through it, then do not break for a new paragraph at that location because very short paragraphs with the same major ideas should be avoided.
