This paper provides an example essay formatted in APA style. This style is commonly used for papers and articles in the social sciences, such as psychology, sociology, education, economics, and certain physical sciences. Many colleges and universities use APA as their standard citation and formatting rules. Before we dive into an example APA paper, we’ll take a look at some of the fundamentals of APA style including paper formatting, in-text citations, and the reference page. After exploring those elements, the remainder of the response will include a long hypothetical example essay in APA style complete with an introduction, body paragraphs, and conclusion. Let’s get started!
General Paper Formatting in APA Style
The basic formatting rules of an APA style paper include:
- Use 12-point Times New Roman font.
- Include a running head at the top of each page that is flush left and contains the title in all capital letters. The running head should be no more than 50 characters, including spaces.
- On the title page, the full title should be centered and typed in upper and lowercase letters. Do not underline, bold, or italicize the title.
- Below the title, type your name (without titles such as Dr. or Ms.), followed by your institutional affiliation.
- Include page numbers in the upper right corner of every page, beginning with the title page counting as page one. The running head appears on this page as well.
- Double space the entire paper, including references, block quotes, tables, and figures.
- Use one-inch margins on all sides of the paper without exception.
- Indent the first line of each paragraph by half an inch using the tab key. Do not use the space bar for indentation.
- Order pages consistently, including title page, abstract page if abstract is included, body of paper with introduction and conclusion, reference page, appendices if applicable, and tables/figures if needed.
With the basics of formatting out of the way, let’s examine in-text citations and the reference page in APA style.
In-Text Citations and Reference List
In-text citations direct readers to specific sources used within the text of the paper and correspond to entries in the reference list at the end. They involve the author’s last name followed by the publication year enclosed in parentheses. For example, “According to Smith (2020).”
When there is no author listed, use the first few words of the source title in italics followed by the publication year. For example, (“The effects of caffeine on behavior,” 2022).
APA in-text citations provide the page number for a direct quotation or paraphrase. For example, “Smith argued that caffeine has limited health risks (2020, p. 23).”
The reference list appears at the end of the paper on its own page with the label “References” centered and in bold at the top. List references alphabetically by author’s last name or title if there is no author. Double space the entire reference list.
Let’s now take a look at a lengthy hypothetical example essay with APA formatting:
The Effect of Caffeine Consumption on Sleep Quality
Caffeinated beverages such as coffee and tea are commonly consumed throughout the world for their stimulating effects. Caffeine is a known disruptor of sleep patterns and overall sleep quality, leading many experts to caution moderate intake in the evenings. This paper will examine the relationship between caffeine consumption and sleep quality based on current scientific literature. Specifically, it will address typical dosages found to inhibit sleep, the biological mechanisms involved, and dietary recommendations for improving sleep hygiene.
Caffeine is one of the most widely used psychoactive substances in the world (Childs & de Wit, 2008). Its popularity stems from the manner in which it acutely improves mood, alertness, and cognitive performance (Glade, 2010). Caffeine’s mechanism of action as an adenosine receptor antagonist lends itself to sleep disturbances as well (Nehlig, 2010). Adenosine plays a key role in facilitating sleep drive and homeostasis, and caffeine interferes with these processes. Laboratory-based research has clearly demonstrated moderate to high caffeine doses ranging from 200 mg to 500 mg, equivalent to 1-3 cups of coffee, taken close to bedtime can lead to sleep latency increases from 5-30 minutes on average (Ruxton, 2008; Palagini et al., 2013). Higher doses of over 500 mg have produced even more substantial sleep disruptions including decreased total sleep time and sleep efficiency (Palagini et al., 2013; Drake et al., 2013).
The biological mechanisms underpinning caffeine-induced sleep impairments center around its antagonism of adenosine A1 and A2A receptors in the central nervous system (Fredholm et al., 1999). By blocking adenosine receptor activity, caffeine prevents its normal inhibitory and sedative effects on wake-promoting regions like the basal forebrain while simultaneously stimulating excitatory pathways (Nehlig, 2010). These combined actions override the body’s sleep drive signals and make falling asleep and remaining asleep more difficult even when tired (Drake et al., 2013). Some evidence also implicates enhanced noradrenergic activity as caffeine triggers the release of norepinephrine, a stress hormone linked to alertness (Childs & Rogers, 2017). Together, caffeine’s blockade of adenosine and stimulation of norepinephrine neurotransmission interfere with sleep at multiple levels of the brain.
In light of the well-established link between caffeine and poor sleep outcomes, certain lifestyle recommendations may help counter its effects and promote better sleep hygiene. Firstly, avoiding caffeine intake 6 hours prior to bedtime is advised to allow sufficient time for half of the caffeine consumed to clear the system (Golomb et al., 2017). For sensitive individuals or those with sleep problems already, even a shorter cutoff time may be necessary. When caffeine cannot be eliminated, lowering intake amounts can make a difference as well. Many experts suggest a daily ceiling of 400 mg, equivalent to 4 cups of coffee, to limit the chance of sleep issues manifesting (Smith et al., 2020). Maintaining consistent sleep-wake patterns, exercising regularly during the day, and limiting screen time before bed are additional sleep-supportive behaviors that may offset any remaining negative impact of caffeine on sleep (Babson et al., 2017). With proper behavioral strategies, caffeine consumption during waking hours need not necessarily sabotage a restful night’s sleep.
Scientific literature provides ample evidence caffeine exerts disruptive effects on sleep through its antagonism of adenosine receptors and enhancement of norepinephrine levels in the brain regions that regulate alertness and sleep-wake cycles. While enjoyable in moderation, caffeine is best eliminated from the daily routine close to bedtime to optimize sleep quality. Limiting intake amounts regardless of timing and incorporating additional healthy sleep habits can further help minimize caffeine-induced sleep disturbances. With an informed understanding of caffeine’s mechanisms of action and appropriate mitigation strategies, individuals can continue enjoying caffeinated beverages during the day without compromising nighttime rest.
We have examined a hypothetical APA formatted example essay on the effects of caffeine consumption on sleep quality. Please note there are still a few minor adjustments that could be made, such as adding paragraph headers, revising sentence structure in places, or including additional citations. The general structure, formatting, and citation conventions modeled meet the basic standards of APA style. I hope this example provides useful insight into writing longer papers using APA guidelines.
