Visual Scanning of Known and Unknown Target Lengths.
Katz, Leonard; Wicklund, David A.
This experiment was designed to test the hypothesis that subjects must know the length of the viewing matter they will be scanning before the target is presented in order to scan efficiently. Adult subjects were required to scan visually for a predetermined item. Targets were one, two, or four letters in length and the pairs of slides shown on each trial were presented via modified Lafayette projection tachistoscopes. Subjects went through two identical sessions. A precise analysis of the data is not presented, but the results--provided in narrative and table format--suggest information that should be of interest for further research. (RB)
