  • Title: The effects of eye movements, spatial attention, and stimulus features on inattentional blindness.
    Author: Koivisto M, Hyönä J, Revonsuo A.
    Journal: Vision Res; 2004 Dec; 44(27):3211-21. PubMed ID: 15482807.
    Abstract:
    Observers often fail to detect the appearance of an unexpected visual object ("inattentional blindness"). Experiment 1 studied the effects of fixation position and spatial attention on inattentional blindness. Eye movements were measured. We found strong inattentional blindness to the unexpected stimulus even when it was fixated and appeared in one of the expected positions. The results suggest that spatial attention is not sufficient for attentional capture and awareness. Experiment 2 showed that the stimulus was easier to consciously detect when it was colored but the relation of the color to the color of the attended objects had no effect on detection. The unexpected stimulus was easiest to detect, when it represented the same category as the attended objects.
