Visitors to heritage sites and museums are governed by time.
Beverley Serrell in her brilliant book, “Exhibit labels, an interpretive approach” talks at some length about time and the visitor. One quote is pretty sobering. “The average time spent in exhibitions ranging from 2,000 – 5,000 sq. feet, regardless of topic, type of museum or modes of presentation is 10 minutes….most visitors will spend under 20 minutes in non ‘big topic’ exhibitions”.
So we interpreters have to achieve maximum transmission of information in a limited amount of time. Serrell discusses time budget planning, where we think about every interpretive element as units of time, such as 4 minutes for these panels, 2 minutes for this film, etc. This is a wise way to proceed when developing elements in exhibits, interactives, labels and text. We want the visitor to look, read and digest. Other techniques assist in achieving this but time is the big one.
Visitors also employ the ‘Fraction of selection’. This is a is the subjective assessment made by the visitor when looking at an interpretive panel or exhibit.
If the effort looks significant for little expected reward then the visitor might well decide to give that panel or text a miss. However, if effort is low and the expected reward is high then the visitor will probably read the text.
The psychologist Schramm was largely responsible for this theory. It seems we human beings have a natural dislike for doing a lot of work for little reward. The same principle applies in interpretative exhibits and text.
These linked apects illustrate that we have to be mindful of the motivations and time restrictions that visitors have, when designing and writing interpretive messages.
This brilliant stuff about how visitors behave is out there in books, articles and on the web. (Heads up for brand new book just hot off the press, which is Stephen Bitgood’s “Social design in museums.” It contains some blistering essays about his work in visitor research. Available from Museums. Etc. http://museumsetc.com/products/social-design
I just don’t know why so many people who design and write interpretation are seemingly unaware of the practical and insightful advice available. It makes the visitors job easier and our own. There you see, I’m just using the fraction of selection!
With time in mind, would you want to read these panels? Sorry for poor image resolution.
