Document Summary

Participants were instructed to point their eyes at the dot and to make judgments about the cross shown just off to the side. However, the dot itself briefly changed to another shape. If participants were not warned about this (and so were not paying attention to the dot), they routinely failed to detect this change even though they had been pointing their eyes right at the dot the whole time. If participants were warned, though, and therefore alert to possible changes, then virtually all participants detected the change. Participants fail to see the shape if they are not warned before, even though they were staring at it. Fail to notice a change in the scene when there is flash between the two pics shown. Early model: the attended inputs are privileged from the start, so the unattended inputs receive little analysis.
