literary terms synthesis

Animal testing is necessary to save human lives. Incidents have happened where humans have died or have been seriously harmed for using drugs that had not been tested on animals (Smith 2008).   

Animals feel pain in a way that is physiologically and neuroanatomically similar to humans (Chowdhury 2012).   

Animal testing is not always used to assess the toxicology of a drug; sometimes painful experiments are undertaken to improve the effectiveness of cosmetics (Turner 2015) 

Animals in distress can suffer psychologically, showing symptoms of depression and anxiety (Panatta and Hudson 2016). 

Whenever you report to a friend the things several other friends have said about a film or CD you engage in synthesis.  People synthesize information naturally to help other see the connections between things they learn;  for example, you have probably stored up a mental data bank of the various things you've heard about particular professors.  If your data bank contains several negative comments, you might synthesize that information and use it to help you decide not to take a class from that particular professor.  Synthesis is related to but not the same as classification, division, or comparison and contrast.  Instead of attending to categories or finding similarities and differences, synthesizing sources is a matter of pulling them together into some kind of harmony.  Synthesis searches for links between materials for the purpose of constructing a thesis or theory.

The basic research report (described below as a background synthesis) is very common in the business world.  Whether one is proposing to open a new store or expand a product line, the report that must inevitably be written will synthesize information and arrange it by topic rather than by source.  Whether you want to present information on child rearing to a new mother, or details about your town to a new resident, you'll find yourself synthesizing too. And just as in college, the quality and usefulness of your synthesis will depend on your accuracy and organization.

In the process of writing his or her background synthesis, the student explored the sources in a new way and become an expert on the topic.  Only when one has reached this degree of expertise is one ready to formulate a thesis.  Frequently writers of background synthesis papers develop a thesis before they have finished.  In the previous example, the student might notice that no two colleges seem to agree on what constitutes "co-curricular," and decide to research this question in more depth, perhaps examining trends in higher education and offering an argument about what this newest trend seems to reveal.  [ More information on developing a research thesis .] 

On the other hand, all research papers are also synthesis papers in that they combine the information you have found in ways that help readers to see that information and the topic in question in a new way.  A research paper with a weak thesis (such as: "media images of women help to shape women's sense of how they should look") will organize its findings to show how this is so without having to spend much time discussing other arguments (in this case, other things that also help to shape women's sense of how they should look).  A paper with a strong thesis (such as "the media is the single most important factor in shaping women's sense of how they should look") will spend more time discussing arguments that it rejects (in this case, each paragraph will show how the media is more influential than other factors in that particular aspect of women's sense of how they should look").

Because each discipline has specific rules and expectations, you should consult your professor or a guide book for that specific discipline if you are asked to write a review of the literature and aren't sure how to do it.

[See also " Preparing to Write the Synthesis Essay ," " Writing the Synthesis Essa y," and " Revision ."]

Regardless of whether you are synthesizing information from prose sources, from laboratory data, or from tables and graphs, your preparation for the synthesis will very likely involve comparison . It may involve analysis , as well, along with classification, and division as you work on your organization. 

Sometimes the wording of your assignment will direct you to what sorts of themes or traits you should look for in your synthesis.  At other times, though, you may be assigned two or more sources and told to synthesize them.  In such cases you need to formulate your own purpose, and develop your own perspectives and interpretations.  A systematic preliminary comparison will help. Begin by summarizing briefly the points, themes, or traits that the texts have in common (you might find summary-outline notes useful here).  Explore different ways to organize the information depending on what you find or what you want to demonstrate ( see above ).  You might find it helpful to make several different outlines or plans before you decide which to use.  As the most important aspect of a synthesis is its organization, you can't spend too long on this aspect of your paper!

A synthesis essay should be organized so that others can understand the sources and evaluate your comprehension of them and their presentation of specific data, themes, etc. The following format works well: 

The introduction (usually one paragraph)     1.    Contains a one-sentence statement that sums up the focus of your synthesis.     2.    Also introduces the texts to be synthesized:             (i)  Gives the title of each source (following the citation guidelines of whatever style                     sheet you are using);               (ii)  Provides the name of each author;             (ii)  Sometimes also provides pertinent background information about the authors,                    about the texts to be summarized, or about the general topic from which the                    texts are drawn. 

The body of a synthesis essay: This should be organized by theme, point, similarity, or aspect of the topic.  Your organization will be determined by the assignment or by the patterns you see in the material you are synthesizing.  The organization is the most important part of a synthesis, so try out more than one format.     Be sure that each paragraph :     1.     Begins with a sentence or phrase that informs readers of the topic of the paragraph;     2.     Includes information from more than one source;     3.     Clearly indicates which material comes from which source using lead in phrases and             in-text citations.  [Beware of plagiarism:  Accidental plagiarism most often occurs             when students are synthesizing sources and do not indicate where the synthesis              ends and their own comments begin or vice verse.]     4.    Shows the similarities or differences between the different sources in ways that make             the paper as informative as possible;     5.    Represents the texts fairly--even if that seems to weaken the paper! Look upon             yourself as a synthesizing machine;  you are simply repeating what the source says,             in fewer words and in your own words.  But the fact that you are using your own              words does not mean that you are in anyway changing what the source says. 

Conclusion. When you have finished your paper, write a conclusion reminding readers of the most significant themes you have found and the ways they connect to the overall topic.  You may also want to suggest further research or comment on things that it was not possible for you to discuss in the paper. If you are writing a background synthesis, in some cases it may be appropriate for you to offer an interpretation of the material or take a position (thesis).  Check this option with your instructor before you write the final draft of your paper. 

• What do you like best about your peer's synthesis? (Why? How might he or she do more of it?);
• Is it clear what is being synthesized? (i.e.: Did your peer list the source(s), and cite it/them correctly?);
• Is it always clear which source your peer is talking about at any given moment? (Mark any places where it is not clear);
• Is the thesis of each original text clear in the synthesis? (Write out what you think each thesis is);
• If you have read the same sources,
• did you identify the same theses as your peer? (If not, how do they differ?);
• did your peer miss any key points from his or her synthesis? (If so, what are they?);
• did your peer include any of his own opinions in his or her synthesis? (If so, what are they?);
• Where there any points in the synthesis where you were lost because a transition was missing or material seems to have been omitted?  (If so, where and how might it be fixed?);
• What is the organizational structure of the synthesis essay? (It might help to draw a plan/diagram);
• Does this structure work?  (If not, how might your peer revise it?);
• How is each paragraph structured?  (It might help to draw a plan/diagram);
• Is this method effective?  (If not, how should your peer revise?);
• Was there a mechanical, grammatical, or spelling error that annoyed you as you read the paper?  (If so, how could the author fix it?  Did you notice this error occurring more than once?)  Do not comment on every typographical or other error you see.  It is a waste of time to carefully edit a paper before it is revised!

• Synesthesia
• Definition & Examples
• When & How to Use Synesthesia

I. What is Synesthesia?

In literature, synesthesia (sin-uh s-thee-zhee-uh), (also spelled synaesthesia) is a rhetorical device that describes or associates one sense in terms of another, most often in the form of a simile. Sensations of touch, taste, see, hear, and smell are expressed as being intertwined or having a connection between them. The term is derived from the neurological condition of the same name, where some people experience an actual link between their senses, where one sense stimulates another—for instance, they may feel like they hear a color, smell a shape, or taste a texture. A person that experiences synesthesia is referred to as a synesthete . As a literary technique, synesthesia reflects this condition.

Synesthesia’s presence in literature is usually through a person or narrator that is characterized as being synesthete, which allows authors to uniquely express that character’s sensations and experiences. But, the feeling of synesthesia isn’t something that all authors are familiar with—on the contrary, it is more rare than common. So, it is actually a unique literary device that we don’t see in everyday writing.

II. Example of Synesthesia

The following sentences provide several examples of synesthesia:

• The bright field of wildflowers smelled like purple, magenta, yellow, white and green.
• The stars sounded like piles of diamonds.
• Her voice was as smooth as pudding.
• The scent of smoke burned my skin.
• The blueberry tasted round in my mouth, the same flavor as a circle.

III. Importance of Synesthesia

Synesthesia allows authors to deliver another level of description in literature. It challenges readers to think out of the box and reinterpret their senses as they know them. Most importantly, though, synesthesia is a unique device that very few authors employ, making it quite notable and distinctive when an author does use it.

IV. Examples of Synesthesia in Literature

The beloved children’s fantasy novel The Phantom Tollbooth is rich with descriptions that use synesthesia. The author Norton Juster is a synesthete, and he used his own sensory perceptions to inspire parts of the book, as you can see in the following passage from Chapter 10: A Colorful Symphony:

“I don’t hear any music,” said Milo. “That’s right,” said Alec; “you don’t listen to this concert—you watch it. Now, pay attention.” As the conductor waved his arms, he molded the air like handfuls of soft clay, and the musicians carefully followed his every direction. “What are they playing?” asked Tock, looking up inquisitively at Alec. “The sunset, of course. They play it every evening about this time.” “They do?” said Milo quizzically. “Naturally,” answered Alec; “and they also play morning, noon and night, when, of course, it’s morning, noon and night. Why, there wouldn’t be any color in the world unless they played it.”

Here, Juster uses synesthesia in the book’s fantasy world to express the idea of a connection between music and colors. Alec explains that the sunset they see every day is actually created by instruments that play colors instead of musical notes. He also tells Milo to “watch” the concert, rather than listen to it, because the instruments will create the colors of the sunset; and all of the colors in the world.

In Inferno of the epic poem The Divine Comedy, Dante uses synesthesia to emphasize a place’s harshness:

E’en such made me that beast withouten peace, Which, coming on against me by degrees Thrust me back thither where the sun is silent.

Here, Dante refers to a place “where the sun is silent.” Our perception of the sun is usually associated with our sense of sight (its brightness) and touch (its heat), but not with any sort of sound. By asserting that the sun is silent, Dante is highlighting the fact that it is absent from the place he is describing. His description has a greater impact than “the sun can’t be seen” or “there is no heat”—“silent” suggests a dark, lifeless, cold and colorless place that never sees the sun.

V. Examples of Synesthesia in Pop Culture

Synesthesia is a popular device in modern advertising, particularly in the food industry. Brands often relate the experience of eating or drinking their product to some other sensory experience—for instance, a brand of chewing gum may suggest that chewing their gum will make you feel a blast of icy cold air. The classic candy Skittles does this in the commercial below:

Skittles uses synesthesia as inspiration for their slogan “Taste the Rainbow.” As we know, a rainbow is an illusion in nature that we only experience through our sight. Skittles plays with the audience’s senses by tempting them to “taste the rainbow” rather than merely see it.

In the Pixar film Ratatouille, Remy is a rat with a very special talent for food. In the scene below, when Remy tastes food, he has an extraordinary sensory experience:

Here, Remy doesn’t just taste the flavors of the strawberries and the cheese. In fact, he doesn’t comment on the flavor at all—instead, each time he takes a bite he hears music and visualizes shapes and designs. When it comes to eating, Remy experiences synesthesia, which could be the secret to his skills.

VI. Conclusion

In conclusion, synesthesia is a unique rhetorical device not found in everyday writing and literature. It uses words to express a completely different form of sensory perception that forces audiences to step outside their normal understanding of taste, touch, sight, smell, and sound and imagine a relationship between them.

Synthesis & theme

Synthesising the content of your analysis means you need to explain and provide an original interpretation of what you've read by highlighting relationships (or lack thereof), between your sources.

Organise and categorise your content into themes or patterns. Examples of themes include:

• Chronological
• Geographical
• Theory, issue or question
• Importance (most to least); or
• Topical (general to specific).

How not to write.

Smith (1970) reported that bilbies come out at night and eat chocolates. Jones (1972) described the variety of beetles eaten by bilbies on their daytime trips. Wheeler (1974) reported that bilbies eat only apples.

How to write.

The elusive bilby has provoked considerable disagreement over such essential facts as whether it is diurnal or nocturnal, and what constitutes its staple diet. Smith (1970) considered them to be nocturnal whereas Jones (1972) reported that they are daytime foragers. A similar disagreement about food preference can be observed in Smith (1970) who  reported bilbies had a fondness for chocolate, and in Jones (1974) who believed bilbies eat beetles and Wheeler (1974) who maintained that apples were the staple food. However, neither chocolate nor apples are indigenous to the bilby habitat, and it seems improbable that they are the main foodstuffs for bilbies.

Chapter 7: Synthesizing Sources

Learning objectives.

At the conclusion of this chapter, you will be able to:

• synthesize key sources connecting them with the research question and topic area.

7.1 Overview of synthesizing

7.1.1 putting the pieces together.

Combining separate elements into a whole is the dictionary definition of synthesis.  It is a way to make connections among and between numerous and varied source materials.  A literature review is not an annotated bibliography, organized by title, author, or date of publication.  Rather, it is grouped by topic to create a whole view of the literature relevant to your research question.

Your synthesis must demonstrate a critical analysis of the papers you collected as well as your ability to integrate the results of your analysis into your own literature review.  Each paper collected should be critically evaluated and weighed for “adequacy, appropriateness, and thoroughness” ( Garrard, 2017 ) before inclusion in your own review.  Papers that do not meet this criteria likely should not be included in your literature review.

Begin the synthesis process by creating a grid, table, or an outline where you will summarize, using common themes you have identified and the sources you have found. The summary grid or outline will help you compare and contrast the themes so you can see the relationships among them as well as areas where you may need to do more searching. Whichever method you choose, this type of organization will help you to both understand the information you find and structure the writing of your review.  Remember, although “the means of summarizing can vary, the key at this point is to make sure you understand what you’ve found and how it relates to your topic and research question” ( Bennard et al., 2014 ).

As you read through the material you gather, look for common themes as they may provide the structure for your literature review.  And, remember, research is an iterative process: it is not unusual to go back and search information sources for more material.

At one extreme, if you are claiming, ‘There are no prior publications on this topic,’ it is more likely that you have not found them yet and may need to broaden your search.  At another extreme, writing a complete literature review can be difficult with a well-trod topic.  Do not cite it all; instead cite what is most relevant.  If that still leaves too much to include, be sure to reference influential sources…as well as high-quality work that clearly connects to the points you make. ( Klingner, Scanlon, & Pressley, 2005 ).

7.2 Creating a summary table

Literature reviews can be organized sequentially or by topic, theme, method, results, theory, or argument.  It’s important to develop categories that are meaningful and relevant to your research question.  Take detailed notes on each article and use a consistent format for capturing all the information each article provides.  These notes and the summary table can be done manually, using note cards.  However, given the amount of information you will be recording, an electronic file created in a word processing or spreadsheet is more manageable. Examples of fields you may want to capture in your notes include:

• Authors’ names
• Article title
• Publication year
• Main purpose of the article
• Methodology or research design
• Participants
• Measurement
• Conclusions

  Other fields that will be useful when you begin to synthesize the sum total of your research:

• Specific details of the article or research that are especially relevant to your study
• Key terms and definitions
• Strengths or weaknesses in research design
• Relationships to other studies
• Possible gaps in the research or literature (for example, many research articles conclude with the statement “more research is needed in this area”)
• Finally, note how closely each article relates to your topic.  You may want to rank these as high, medium, or low relevance.  For papers that you decide not to include, you may want to note your reasoning for exclusion, such as ‘small sample size’, ‘local case study,’ or ‘lacks evidence to support assertion.’

This short video demonstrates how a nursing researcher might create a summary table.

7.2.1 Creating a Summary Table

  Summary tables can be organized by author or by theme, for example:

For a summary table template, see http://blogs.monm.edu/writingatmc/files/2013/04/Synthesis-Matrix-Template.pdf

7.3 Creating a summary outline

An alternate way to organize your articles for synthesis it to create an outline. After you have collected the articles you intend to use (and have put aside the ones you won’t be using), it’s time to identify the conclusions that can be drawn from the articles as a group.

  Based on your review of the collected articles, group them by categories.  You may wish to further organize them by topic and then chronologically or alphabetically by author.  For each topic or subtopic you identified during your critical analysis of the paper, determine what those papers have in common.  Likewise, determine which ones in the group differ.  If there are contradictory findings, you may be able to identify methodological or theoretical differences that could account for the contradiction (for example, differences in population demographics).  Determine what general conclusions you can report about the topic or subtopic as the entire group of studies relate to it.  For example, you may have several studies that agree on outcome, such as ‘hands on learning is best for science in elementary school’ or that ‘continuing education is the best method for updating nursing certification.’ In that case, you may want to organize by methodology used in the studies rather than by outcome.

Organize your outline in a logical order and prepare to write the first draft of your literature review.  That order might be from broad to more specific, or it may be sequential or chronological, going from foundational literature to more current.  Remember, “an effective literature review need not denote the entire historical record, but rather establish the raison d’etre for the current study and in doing so cite that literature distinctly pertinent for theoretical, methodological, or empirical reasons.” ( Milardo, 2015, p. 22 ).

As you organize the summarized documents into a logical structure, you are also appraising and synthesizing complex information from multiple sources.  Your literature review is the result of your research that synthesizes new and old information and creates new knowledge.

What is Synthesis

What is Synthesis? Synthesis writing is a form of analysis related to comparison and contrast, classification and division. On a basic level, synthesis requires the writer to pull together two or more summaries, looking for themes in each text. In synthesis, you search for the links between various materials in order to make your point. Most advanced academic writing, including literature reviews, relies heavily on synthesis. (Temple University Writing Center)  

How To Synthesize Sources in a Literature Review

Literature reviews synthesize large amounts of information and present it in a coherent, organized fashion. In a literature review you will be combining material from several texts to create a new text – your literature review.

You will use common points among the sources you have gathered to help you synthesize the material. This will help ensure that your literature review is organized by subtopic, not by source. This means various authors' names can appear and reappear throughout the literature review, and each paragraph will mention several different authors. 

When you shift from writing summaries of the content of a source to synthesizing content from sources, there is a number things you must keep in mind: 

• Look for specific connections and or links between your sources and how those relate to your thesis or question.
• When writing and organizing your literature review be aware that your readers need to understand how and why the information from the different sources overlap.
• Organize your literature review by the themes you find within your sources or themes you have identified.

Synthesis and Literature Reviews

Why do we seek to understand the ways that authors or sources “converse” with one another?

So that we can synthesize various perspectives on a topic to more deeply understand it .

In academic writing, this understanding of the “conversation” may become the content of an explanatory synthesis paper – a paper in which you, the writer, point out various various themes or key points from a conversation on a particular topic.

Or, another assignment that you may complete in college is a literature review , which applies your synthesis skills. Literature reviews are often found in the beginning of scholarly journal articles. Literature reviews synthesize previous research that has been done on a particular topic, summarizing important works in the history of research on that topic.

• Literature reviews can be arranged by topic or theme , much like a traditional explanatory synthesis paper.
• Literature reviews can also be arranged chronologically , according to various time periods of research on a topic (i.e., what was published ten years ago, five years ago, and within the last year, for example).
• Finally, literature reviews can be arranged by discipline or field (i.e., what is the current research being done by biologists on this topic? What is the current research being done by psychologists on this topic? What is the current research being done by [insert academic discipline] on this topic?).

Just like in an explanatory synthesis paper, a Literature Review offers  only  a report on what others have already written about. The Literature Review does not reflect the author’s own argument or contributions to the field of research. Instead, it indicates that the author has read others’ important contributions and understands what has come before him or her.

The Literature Review provides context for the author’s own new research. It is the basis and background out of which the author’s research grows. Context = credibility in academic writing. When authors have broad Literature Review, they demonstrate their credibility as researchers.

Synesthesia

Synesthesia definition, everyday life examples of synesthesia, examples of synesthesia in literature, example #1: the divine comedy (by dante alighieri).

Dante Alighieri’s The Divine Comedy contains a good synesthesia example in literature. In the first canto , the poet tells us about a place called “ Inferno .” He says,

“Back to the region where the sun is silent .”

Example #2: Ode to a Nightingale (By John Keats)

“Tasting of Flora and the country green, Dance, and Provencal song, and sun burnt mirth!”

“In some melodious plot , Of beechen green, Singest of summer in full throated ease.”

Keats associates the act of melodious singing with a plot covered with green beechen trees , and thus connects visual sense with the sense of hearing.

Example #3: King Lear (By William Shakespeare)

“Thou art a lady: if only to go warm were gorgeous, Why nature needs not what thou gorgeous wear’st, Which scarcely keeps thee warm.”

Example #4: A Tuft of Flowers (By Robert Frost)

“ The butterfly and I had lit upon, Nevertheless, a message from the dawn, That made me hear the wakening birds around, And hear his long scythe whispering to the ground…”

In the above excerpt, the speaker reveals a blend of sensory experiences he is experiencing. The speaker’s visual sense and his sense of hearing make him aware of his surroundings.

Example #5: Dying (By Emily Dickinson)

“With blue, uncertain, stumbling buzz, Between the light and me; And then the windows failed, and then could not see to see.”

Example #6: The Whole World Over (By Julia Glass)

“The word would fill her mind for a few minutes with a single color: not an unpleasant sensation but still an intrusion… Patriarch: Brown, she thought, a temple of a word, a shiny red brown, like the surface of a chestnut.”

These lines are comments spoken by Duffy, who thinks that Saga’s synesthesia is a distraction.

On This Page:

When you write a literature review or essay, you have to go beyond just summarizing the articles you’ve read – you need to synthesize the literature to show how it all fits together (and how your own research fits in).

Synthesizing simply means combining. Instead of summarizing the main points of each source in turn, you put together the ideas and findings of multiple sources in order to make an overall point.

At the most basic level, this involves looking for similarities and differences between your sources. Your synthesis should show the reader where the sources overlap and where they diverge.

Unsynthesized Example

Franz (2008) studied undergraduate online students. He looked at 17 females and 18 males and found that none of them liked APA. According to Franz, the evidence suggested that all students are reluctant to learn citations style. Perez (2010) also studies undergraduate students. She looked at 42 females and 50 males and found that males were significantly more inclined to use citation software ( p < .05). Findings suggest that females might graduate sooner. Goldstein (2012) looked at British undergraduates. Among a sample of 50, all females, all confident in their abilities to cite and were eager to write their dissertations.

Synthesized Example

Studies of undergraduate students reveal conflicting conclusions regarding relationships between advanced scholarly study and citation efficacy. Although Franz (2008) found that no participants enjoyed learning citation style, Goldstein (2012) determined in a larger study that all participants watched felt comfortable citing sources, suggesting that variables among participant and control group populations must be examined more closely. Although Perez (2010) expanded on Franz’s original study with a larger, more diverse sample…

Step 1: Organize your sources

After collecting the relevant literature, you’ve got a lot of information to work through, and no clear idea of how it all fits together.

Before you can start writing, you need to organize your notes in a way that allows you to see the relationships between sources.

One way to begin synthesizing the literature is to put your notes into a table. Depending on your topic and the type of literature you’re dealing with, there are a couple of different ways you can organize this.

Summary table

A summary table collates the key points of each source under consistent headings. This is a good approach if your sources tend to have a similar structure – for instance, if they’re all empirical papers.

Each row in the table lists one source, and each column identifies a specific part of the source. You can decide which headings to include based on what’s most relevant to the literature you’re dealing with.

For example, you might include columns for things like aims, methods, variables, population, sample size, and conclusion.

For each study, you briefly summarize each of these aspects. You can also include columns for your own evaluation and analysis.

The summary table gives you a quick overview of the key points of each source. This allows you to group sources by relevant similarities, as well as noticing important differences or contradictions in their findings.

A synthesis matrix is useful when your sources are more varied in their purpose and structure – for example, when you’re dealing with books and essays making various different arguments about a topic.

Each column in the table lists one source. Each row is labeled with a specific concept, topic or theme that recurs across all or most of the sources.

Then, for each source, you summarize the main points or arguments related to the theme.

The purposes of the table is to identify the common points that connect the sources, as well as identifying points where they diverge or disagree.

Step 2: Outline your structure

Now you should have a clear overview of the main connections and differences between the sources you’ve read. Next, you need to decide how you’ll group them together and the order in which you’ll discuss them.

For shorter papers, your outline can just identify the focus of each paragraph; for longer papers, you might want to divide it into sections with headings.

There are a few different approaches you can take to help you structure your synthesis.

If your sources cover a broad time period, and you found patterns in how researchers approached the topic over time, you can organize your discussion chronologically .

That doesn’t mean you just summarize each paper in chronological order; instead, you should group articles into time periods and identify what they have in common, as well as signalling important turning points or developments in the literature.

If the literature covers various different topics, you can organize it thematically .

That means that each paragraph or section focuses on a specific theme and explains how that theme is approached in the literature.

Source Used with Permission: The Chicago School

If you’re drawing on literature from various different fields or they use a wide variety of research methods, you can organize your sources methodologically .

That means grouping together studies based on the type of research they did and discussing the findings that emerged from each method.

If your topic involves a debate between different schools of thought, you can organize it theoretically .

That means comparing the different theories that have been developed and grouping together papers based on the position or perspective they take on the topic, as well as evaluating which arguments are most convincing.

Step 3: Write paragraphs with topic sentences

What sets a synthesis apart from a summary is that it combines various sources. The easiest way to think about this is that each paragraph should discuss a few different sources, and you should be able to condense the overall point of the paragraph into one sentence.

This is called a topic sentence , and it usually appears at the start of the paragraph. The topic sentence signals what the whole paragraph is about; every sentence in the paragraph should be clearly related to it.

A topic sentence can be a simple summary of the paragraph’s content:

“Early research on [x] focused heavily on [y].”

For an effective synthesis, you can use topic sentences to link back to the previous paragraph, highlighting a point of debate or critique:

“Several scholars have pointed out the flaws in this approach.” “While recent research has attempted to address the problem, many of these studies have methodological flaws that limit their validity.”

By using topic sentences, you can ensure that your paragraphs are coherent and clearly show the connections between the articles you are discussing.

As you write your paragraphs, avoid quoting directly from sources: use your own words to explain the commonalities and differences that you found in the literature.

Don’t try to cover every single point from every single source – the key to synthesizing is to extract the most important and relevant information and combine it to give your reader an overall picture of the state of knowledge on your topic.

Step 4: Revise, edit and proofread

Like any other piece of academic writing, synthesizing literature doesn’t happen all in one go – it involves redrafting, revising, editing and proofreading your work.

Checklist for Synthesis

•   Do I introduce the paragraph with a clear, focused topic sentence?
•   Do I discuss more than one source in the paragraph?
•   Do I mention only the most relevant findings, rather than describing every part of the studies?
•   Do I discuss the similarities or differences between the sources, rather than summarizing each source in turn?
•   Do I put the findings or arguments of the sources in my own words?
•   Is the paragraph organized around a single idea?
•   Is the paragraph directly relevant to my research question or topic?
•   Is there a logical transition from this paragraph to the next one?

Synthesizing Sources

Welcome to the Purdue OWL

When you look for areas where your sources agree or disagree and try to draw broader conclusions about your topic based on what your sources say, you are engaging in synthesis. Writing a research paper usually requires synthesizing the available sources in order to provide new insight or a different perspective into your particular topic (as opposed to simply restating what each individual source says about your research topic).

Note that synthesizing is not the same as summarizing.  

• A summary restates the information in one or more sources without providing new insight or reaching new conclusions.
• A synthesis draws on multiple sources to reach a broader conclusion.

There are two types of syntheses: explanatory syntheses and argumentative syntheses . Explanatory syntheses seek to bring sources together to explain a perspective and the reasoning behind it. Argumentative syntheses seek to bring sources together to make an argument. Both types of synthesis involve looking for relationships between sources and drawing conclusions.

In order to successfully synthesize your sources, you might begin by grouping your sources by topic and looking for connections. For example, if you were researching the pros and cons of encouraging healthy eating in children, you would want to separate your sources to find which ones agree with each other and which ones disagree.

After you have a good idea of what your sources are saying, you want to construct your body paragraphs in a way that acknowledges different sources and highlights where you can draw new conclusions.

As you continue synthesizing, here are a few points to remember:

• Don’t force a relationship between sources if there isn’t one. Not all of your sources have to complement one another.
• Do your best to highlight the relationships between sources in very clear ways.
• Don’t ignore any outliers in your research. It’s important to take note of every perspective (even those that disagree with your broader conclusions).

Example Syntheses

Below are two examples of synthesis: one where synthesis is NOT utilized well, and one where it is.

Parents are always trying to find ways to encourage healthy eating in their children. Elena Pearl Ben-Joseph, a doctor and writer for KidsHealth , encourages parents to be role models for their children by not dieting or vocalizing concerns about their body image. The first popular diet began in 1863. William Banting named it the “Banting” diet after himself, and it consisted of eating fruits, vegetables, meat, and dry wine. Despite the fact that dieting has been around for over a hundred and fifty years, parents should not diet because it hinders children’s understanding of healthy eating.

In this sample paragraph, the paragraph begins with one idea then drastically shifts to another. Rather than comparing the sources, the author simply describes their content. This leads the paragraph to veer in an different direction at the end, and it prevents the paragraph from expressing any strong arguments or conclusions.

An example of a stronger synthesis can be found below.

Parents are always trying to find ways to encourage healthy eating in their children. Different scientists and educators have different strategies for promoting a well-rounded diet while still encouraging body positivity in children. David R. Just and Joseph Price suggest in their article “Using Incentives to Encourage Healthy Eating in Children” that children are more likely to eat fruits and vegetables if they are given a reward (855-856). Similarly, Elena Pearl Ben-Joseph, a doctor and writer for Kids Health , encourages parents to be role models for their children. She states that “parents who are always dieting or complaining about their bodies may foster these same negative feelings in their kids. Try to keep a positive approach about food” (Ben-Joseph). Martha J. Nepper and Weiwen Chai support Ben-Joseph’s suggestions in their article “Parents’ Barriers and Strategies to Promote Healthy Eating among School-age Children.” Nepper and Chai note, “Parents felt that patience, consistency, educating themselves on proper nutrition, and having more healthy foods available in the home were important strategies when developing healthy eating habits for their children.” By following some of these ideas, parents can help their children develop healthy eating habits while still maintaining body positivity.

In this example, the author puts different sources in conversation with one another. Rather than simply describing the content of the sources in order, the author uses transitions (like "similarly") and makes the relationship between the sources evident.
