The effects of fixation, attention, and report on the frequency and duration of visual disappearances
The effects of fixation, attention, and report on the frequency and duration of visual disappearances
Subjects viewed steadily two luminous dots with various instructions as to where to fixate and attend, and what disappearances to report. An analysis of the results showed that the frequency and duration of disappearances was significantly influenced by fixation, attention, and report. A control indicated that the attention effect was not simply due to missing unattended events. It was suggested that these uncontrolled factors might have confounded some of the visual disappearance research results and that attention might be the primary determinant of the meaningful perceptual unit effect.

Abstract
Subjects viewed steadily two luminous dots with various instructions as to where to fixate and attend, and what disappearances to report. An analysis of the results showed that the frequency and duration of disappearances was significantly influenced by fixation, attention, and report. A control indicated that the attention effect was not simply due to missing unattended events. It was suggested that these uncontrolled factors might have confounded some of the visual disappearance research results and that attention might be the primary determinant of the meaningful perceptual unit effect.
