Reader Expectation Research:
The Science
“The empirical test, which I demand as a scientist, is that I would show it to people before and after… they were able to follow it much more clearly when I used the Gopen method… putting things where the reader expects.”

Reader expectation research is consistent with decades of work in cognitive psychology and psycholinguistics.
The central premise and interrelated concepts of George David Gopen’s Reader Expectation Approach are supported by independent research in cognitive psychology and psycholinguistics. Studies by Glanzer & Cunitz (1966), Clark & Haviland (1977), Vande Kopple (1982), and Pickering & Gambi (2018), confirm that readers of English process and retain information more easily when writers place content in locations that match reader structural expectations.
The Central Premise of REA
Readers bring structural expectations to every sentence and paragraph.
Readers take the great majority of their clues for making sense of a sentence not from what the words are nor from what they might mean, but rather from where in the sentence they show up.— George David Gopen
Supporting Research
In “Predicting While Comprehending,” Martin J. Pickering and Chiara Gambi demonstrated that language comprehension operates through active prediction. Readers continuously anticipated upcoming linguistic content at multiple levels, including syntactic structure.
Interrelated Concepts of REA
I. Depleting “reader energy” impedes comprehension.
At the beginning of each reading experience, readers summon the necessary reader energy which will be required to bring that experience to a closure. When readers find all the material they expect to find in all the places they expect to find it, they use the minimal amount of reader energy. If these structural expectations are continually violated, readers are forced to divert energy from understanding the content of a passage to unraveling its structure. — George David Gopen

Pickering and Gambi also illustrated that readers processed information more efficiently when it arrived in the location in which it was expected to arrive. When information the readers expected was not located in the expected location, additional cognitive resources were required to reanalyze the text; this in turn reduced comprehension by increasing the difficulty of processing.
II. Context controls meaning.
Readers perceive from left to right and through time as they read the English language. Anything that appears whether a word, a phrase, a clause, or anything larger, appears in the context of what has preceded it. REA directs the writer to establish context, sentence by sentence. — George David Gopen
Supporting Research
In “Comprehension and the Given-New Contract,” Herbert H. Clark and Susan E. Haviland discovered that readers of English expect sentences to open with familiar, contextualizing information and to close with new, emphasized information. They termed this “the given-new contract.”
III. Good writing is always characterized by a reader’s sense of moving forward.
Moving forward in a sentence is directly connected to a reader’s expectation of where they might be going from here. Anytime a reader has to turn back, confusion can ensue and reader energy can be wasted. — George David Gopen

Clark and Haviland also showed that when sentences are structured so that Given information comes first and New information follows, readers process them more easily and remember them better. Reversing the order of the information presented increased processing difficulty and decreased retention, even though the factual content was identical.
IV. Well-controlled sentence connectivity improves the flow of thought.
For a reader to follow the progression of a writer’s thought, each sentence must announce as soon as possible how it connects backward. When readers can make these connections without effort, they progress through a paragraph with a minimal expenditure of reader energy— George David Gopen
Supporting Research
In “The given-new strategy of comprehension and some natural expository paragraphs,” William J. Vande Kopple demonstrated that readers integrate new information directly into the memory node holding the given information from the preceding sentence. When each sentence opens with information that connects backward to what preceded it, readers build connected understanding across a paragraph without effort. When that backward connection is absent or unclear, readers must expend additional cognitive resources searching for the link — interrupting the forward progression of their comprehension.
V. Readers emphasize words that appear in a sentence’s “stress positions.”
The human need for closure extends to the act of reading — operating at the level of every individual sentence. Readers naturally emphasize the material that arrives at the end of a sentence. We refer to that location as a ‘stress position.’ — George David Gopen
Supporting Research
In his 1885 book, Memory, Hermann Ebbinghaus first identified what he termed the serial position effect. He found that memory recall accuracy varies based on the item’s linear position in a series.
In “The serial position effect of free recall,” B. B. Murdock plotted the serial position effect curve — detailing the primacy effect and the recency effect located at either end of the curve’s characteristic U-shape (image below). The primacy effect is the phenomenon of remembering the first item in a series better than items in the middle. The recency effect is the phenomenon of remembering the last item in a series better than even the first.
In “Serial Position Effect,” Glanzer & Cunitz (1966) explained that the recency effect exists because the last items in a sequence remain active in short-term memory at the moment of recall.

From Research to Results: REA’s Real-world Impact
The research collected here represents an independent body of scientific literature that has arrived at conclusions consistent with the concepts George David Gopen developed through his own close analysis of how readers respond to prose. That the findings of cognitive psychology and psycholinguistics align so precisely with REA is not coincidental — it is confirmation. For over four decades, tens of thousands of professionals have experienced the results of REA firsthand: Many who had never succeeded in getting a grant funded before adopting REA found themselves succeeding with every grant application thereafter. To see what that looks like in practice, explore the real-world outcomes of REA training at leading institutions worldwide.
