Dichotic Listening Experiment - Answers -Receive different messages in each ear to
test attended information vs. unattended
Broadbent's Filter Model - Answers -Early-selection model
Filters message before incoming information is analyzed for meaning
Sensory Memory - Answers -Holds all incoming information for a fraction of a second,
then transfers it all to the next stage
Filter - Answers -part of Broadbent's Filter model, only allows the attended message to
be passed on to the next stage
Detector - Answers -Part of Broadbent's Filter Model that processes all information to
determine higher level characteristics of the message
Short-Term Memory - Answers -Holds small amount of information for about 10-15
seconds before potentially transferring it to long-term memory
Treisman's Attenuation Theory - Answers -Intermediate-selection model
Attended message can be separated from unattended message early in the information-
processing system
Selection can also occur later
Attenuator - Answers -part of Treisman's Theory, it analyzes the incoming message in
terms of physical characteristics, language, and meaning
the attended message is much stronger than the unattended
Dictionary Unit - Answers -A component of Treisman's attenuation model of attention.
This processing unit contains stored words and thresholds for activating the words.
Divided Attention - Answers -simultaneously do two things at once
