Since written English is often highly redundant, much of the material can be omitted
without any loss of meaning; a large proportion of information in a text can be
absorbed using peripheral vision and nonvisual informaton. Words that are highly
likely to occur in a given context do not have to be checked by looking directly at
them - peripheral vision can check that they are what is expected even while the eye
is fixating elsewhere.
When you read the message below are you using more visual or nonvisual
information? What you see or what you expect to see?

RANDOM LIMITATIONS
• There is a limit to how much can be seen at
any one time, and that limit in terms of
random letters is four or five.
• There is a limit to the rate at which the brain
can identify random letters in reading, and
that rate is four or five letters per second.
SNEEZE FURY HORSES WHEN AGAIN
WORDS
• When letters are organized into words readers
can generally identify the equivalent of ten or a
dozen letters or more.
• The amount of visual information required to
identify a single letter is cut by half if the letter
occurs in a word.
• You don’t read each letter individually. Your brain
processes them as words.
EARLY FROSTS HARM THE CROPS
NONVISUAL INFORMATION FROM
SENSE
• One glance at a meaningful sentence of English
words allows you to see everything – all 25 letters
– four or five words instead of four or five letters.
• The amount of visual information available to the
brain in each demonstration was the same, but
with a sequence of words that make sense you
can read much more in the same amount of time.
