    Brief History

    Psychological research on reading was donein the early 1900s by E. B. Huey and others

    According to Huey (1908): . . .to completelyanalyze what we do when we read wouldalmost be the acme of a psychologistsachievements, for it would be to describe very

    many of the most intricate workings of thehuman mind . . . .

    With the rise of Behaviorism in the early partof the last century, especially within Americanpsychology, the focus shifted to studying

    behaviors that were more observable thanreading (more simple learning and moresimple learners)

    As cognitive psychology became increasingly

    dominant during the latter half of the century,reading (and human thinking in general)again became a phenomenon to study

    How might we think about reading?

    Perhaps because oflasting effects ofBehaviorism, many earlymodels of reading still had

    a very stimulus-driven,or text-driven feel

    In these early models, theassumption was thatinformation in the text is

    taken in by the reader Information was seen to

    flow from the bottom up

    An Early Bottom-Up Model of

    Reading, LaBerge & Samuels (1972)

    Letters are perceived asvisual patterns, and withlearning, come to be

    recognized as letters Letters are mentally

    combined and recognizedas words

    Words are successivelyrecognized as phrases,sentences, etc.

    Not the whole story

    To test such a text-driven model, you cannow be a subject in an experiment thatEdmund Burke Huey performed 100 yearsago (with slightly different technology)

    When you click the mouse or spacebar, youwill see an asterisk ( * ) appear on the screento orient you. A vertical list of items (letters orwords) will then appear under the asterisk

    See how many of the items you can read inthe time you are given (if possible, read outloud, in a rapid but comfortable pace)

    Did you finish the whole list?

    If you are like most adult readers, you hadtime to read all the items on all the lists

    Click to advance each screen again

    What does this demonstrate?

    We do not read letter by letter, building upwords from individual letters

    The lists contained successively more letters

    List 1: 1 letter per line List 2: 4 letters per line

    List 3: 8 letters per line

    However, the lists were not displayed forproportionately longer times

    All lists were displayed for 8 seconds

    You just replicated classic findings

    You read the short words (4 letter words inList 2) just as quickly as you read singleletters (List 1); both were displayed for only 8seconds

    Even though List 3 contained eight timesmore letters than List 1, you did not needeight times longer to read it

    In studies with more precise timing, peopleeven read short words more quickly thansingle letters, a phenomenon that has cometo be called the word superiority effect

    Alternative models of reading

    Theoretical modelsemphasizing theexpectations andprediction abilities ofreaders have come to beknown as top-downmodels
