Abstract
The purpose of the experiment was to evaluate pre-defined
display formatting from the standpoint of response accuracy
and reaction time for use with a tactical information display
for the U.S. Navy. Subjects were required to retain a single
consonant probe in short term memory while searching one of
six pre-formatted displays for a target label. Upon detecting
the target a keyboard entry was made reflecting the data
associated with that target label. The subject was then
presented with a two or four letter set from which he was to
indicate the presence or absence of the memory probe. Reaction
time increased and response accuracy decreased to a
highly correlated and statistically significant level as the
number of elements in the display screen increased. The
secondary memory probe task was not found to have a statistically
significant effect on the search reaction time
among the 24 subjects who participated in the experiment.
