Document Summary
2) deutch & deutch"s late selection theory, places broadband selective filter after perceptual processes. Do register and assign everything meaning but then selective filter decides what you pass on to conscious awareness. Deutsch and deutsch"s late selection theory moved the selective filter from before perception to after the perceptual process. Instead of complete selective filter, have an attenuator weakens but doesn"t eliminate input from unattended ear. Then some gets to perceptual processes, so still assign meaning to stuff in unattended ear, just not high priority. Treisman"s attenuation theory replaced the selective filter with an attenuator, which selectively allows the attended message to be processed to a greater extent than the unattended message. Sensory register attenuator perceptual process conscious. Acronym: johnson & johnson and heinz catch-up can be anywhere: still debate about which theory is best, but the three theories are pivotal in our understanding of selective attention.
