Demonstration Part 2

You will be presented with another stimulus. Again, focus on the flashing green circle in the centre of the stimulus. Press the play button when you are ready to begin.

What happened to the yellow dots as you viewed this stimulus?

Most people see the yellow dots disappear when shown as part of a stimulus that is rotating, but not when shown in a stationary stimulus. Because the dots only disappear in the context of a moving stimulus, this phenomenon is called motion-induced blindness (MIB). In MIB, the points that vanish are still sensed, but perception of those areas is prevented from reaching consciousness.

One question is whether motion-induced blindness actually requires motion to work. Click next to test whether motion is needed for MIB.
