Seventeen subjects searched for, and then monitored, 3, 6, or 9 stationary targets in order to
detect and shoot 3 threats. The targets were located in an area 1200 left and right and 900 …

Measurements were made of subjects' head movements as they found and memorized the
position of targets located around them. Four factors were manipulated: the size of the field …

Seventeen subjects were presented with stationary targets at random locations in an area
120 left and right and 90 deg upwards from straight ahead. Targets would change shape to …
