Any change to the interpretive setting creates a change in the pattern of visitor attention to the whole milieu.
According to the attention framework,this redistribution is the result of a combination of
moment-to-moment selectivity, motivated focusing,and depletion of the reserves of attention. In an interpretive environment dense with stimulation, the capacity of attention is likely to be depleted before all elements have received an adequate level of attention.
Also, in a densely stimulating environment,only the most distinctive elements are likely to receive attention because of the selectivity principle.
The limitations of attention require that designers plan the interpretive experiences carefully so that visitors distribute their attention to focus on important messages and objects.
