THE USE OF REFERENCE SIGNALS IN A VISUAL VIGILANCE TASK. II. REFERENCE SIGNALS DISPLAYED WHEN DEMANDED AND WHEN ARBITRARILY PROGRAMMED,
Abstract
The purpose of this experiment was to determine whether or not performance on a visual vigilance task is aided by displaying reference signals adjacent to the display constituting the vigilance task. Four conditions were studied. In a control condition the adjacent reference display was never employed. In a second condition the observers could demand activation of the reference display whenever they wished, and reference signals were generated during the activation period. In a third condition the experimenter activated the reference display at arbitrarily chosen intervals and reference signals were generated during the activation period. In a fourth condition the experimenter activated the reference display at arbitrarily chosen intervals but reference signals were never generated. Ninety-six observers were employed, 24 in each condition. (Author)
