Paper Abstract
In 1967 Ulric Neisser, studying how laypeople examined pictures, hypothesized that image
perception occurs in two stages, a pre-attentive stage in which the entire image is processed in
parallel, where a 'holistic' view of what is being displayed is formed, and a secondary stage in which
items or groups of items are examined by focal attention. Later, the proponents of Neisser's theory
suggested that the pre-attentive stage may bias the selection of the areas that will be subjected to
further analysis. This is easily seen in those dual interpretation figures; once one 'sees' the figure in
a certain way, it is very hard to instruct the eye-brain system to let go of that perception and 'see'
the figure in the alternative way. In medical image perception, Harold Kundel and Calvin Nodine
proposed a model of medical image interpretation that is based upon Neisser's two stages, and
have become so convinced of the influence of the 'holistic' view on the subsequent reading of the
image that they have recently questioned the traditional framework that determines how lesions are
found. In other words, as opposed to the traditional view of SEARCH THE IMAGE - DETECT A
POSSIBLE FINDING - IDENTIFY THE FINDING - DECIDE WHAT TO DO ABOUT THE IMAGE,
Kundel and Nodine have recently suggested a new framework: DETECT A POSSIBLE FINDING -
IDENTIFY THE FINDING - SEARCH THE IMAGE - DECIDE WHAT TO DO ABOUT THE IMAGE.
In light of this significant switch, we decided to investigate what happens when the 'holistic' view is
incorrect.
