Orienting: to sensory events; spatial, non- spatial. Central executive: search, selection for further processing. Moving spotlight zoom lens gain resource allocation (costs and benefits) Inhibition of the surrounding area filter or sieve gate, channel bottleneck resource allocation ( costs and benefits) Controlled primarily controlled by top-down, conceptually- driven processes. Participants wore headphones, with an attended channel input (sound that they paid attention to) and an unattended channel input (sound that they ignored) Repeat what they were hearing in the attended ear.
