Description
Heleen Slagter and co-workers used brain imaging to watch conscious targets compete over time in PLOS ONE in 2010. The mind can only handle so much at once. That limit shows in the attentional blink: a second target seen too soon after a first is often missed. Theories agree the blink reflects competition for conscious access. The team scanned brains while subjects faced rapid streams with two targets.
Imaging revealed how brain activity for the targets rose and fell against each other. Neural competition, not simple erasure, seems to cause the blink. That view helps explain why the second target sometimes survives. It also links a classic psychology effect to measurable brain dynamics. Consciousness research gains a timed map of a bottleneck.
