Quizplus · Accepted Answer

Treisman's attenuator produces two levels of output, where the attended message is amplified and the unattended message is still present but reduced in strength. The other components mentioned do not produce two levels of output. Treisman's filter only allows one message to pass through, McKay's dictionary unit matches incoming stimuli to stored representations, and Broadbent's detector identifies specific features of stimuli but does not produce two levels of output.
