Did you ever play the party game where multiple items are displayed on a tray;

everyone gets to look at the tray for one minute, then the tray is removed and

you write down as many items as you can remember?

 

That is because of the way the brain processes information. Earlier in this series

we said the purpose of the cover, is to attract the readers’ attention. When it

does, the reader’s mind very rapidly decides to activate memory and process

the information. Or not.

 

Assuming the reader decides to pay attention - the information goes to short

term memory. If you’ve played the “What’s-on- the- tray?” game, you probably

noticed that short-term memory has very limited capacity and short storage time.

In a bright mind on a good day, short term memory holds seven items. It lasts

less than 1 minute. For many, especially those with low literacy and high stress,

it holds less. And here’s the thing: the more items on the tray, the less you

remember. When short-term memory hits capacity, it dumps everything.

 

The parlor game is easier when the items on the tray are organized -- ”chunked”

into groups of related items. Chunking helps the mind associate the items with

something it already knows. Association gives the brain a place in to put the

information in long-term memory, so you can recall it.  Maybe the tray contained

kitchen utensils (spoon, can opener, peeler), bathroom items (toothbrush, comb,

soap) and writing implements (pencil, pen, marker). These chunks are easier to

think about than a bunch of stuff.

 

It’s the same with printed information: use subheads to chunk a list of items into

logical groups that link the information to something the reader already knows.

 

SAM says that in Superior health education materials, lists are grouped under

descriptive subheadings with no group having more than five items.

 

The Beginnings Parent’s Guide’s  Home Safety Checklist for infants up to 12

weeks old in the is a good example. It’s on page 25; take a look.  The instruction

is divided into four chunks: fire safety, sleep safety, burn safety and air safety.

Each chunk covers one to three items. In addition to increasing comprehension,

this chunking makes the checklist look and feel do-able.
