Verb Tense: An Overview

Verb tenses place actions in time, expressing whether the actions already took place (past), are currently taking place (present), or will be taking place (future). In scholarly writing, the most common verb tenses we use are the following:

Use the simple present to describe a general truth, an action that is happening now, or an action that occurs on a regular basis:

Example:  The hospital admits patients whether or not they have proof of insurance.

Use the simple past tense to describe an action that took place at a specific point in the past:

Example:  Zimbardo (1998) researched many aspects of social psychology.

Use the future tense to describe an action that will take place at a particular point in the future (particularly useful when writing abstracts for papers):

Example:  In this Breadth section, I will discuss literature pertaining to current healthcare policy.

Verb Tense: APA Guidelines

In addition to calling for consistency and accuracy, APA formatting calls for the use of specific verb tenses for paraphrasing and analyzing research. Generally speaking, research results should be described in the past tense because the research took place at a particular moment in the past:

ExampleSmith (2011) found that...

However, you may refer to findings that still hold true in the present tense:

Example:  Smith (2011) found that the treatment is effective.
