are attending to that message

,©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.

Broadbent's Filter Model: sensory memory - ✔✔holds all incoming

information for a fraction of a second, transfers all information to the next

stage

Broadbent's Filter Model: filter - ✔✔identifies attended message based on

physical characteristics, only attended message is passed on to the next

stage

Broadbent's Filter Model: detector - ✔✔processes the information received

to determine the meaning of the message

Broadbent's Filter Model: short-term memory - ✔✔receives output of

detector, holds information for 10-15 seconds and may transfer it to long-

term memory

What could Broadbent's model not explain? - ✔✔participant's name gets

through, participants can shadow meaningful messages that switch from

one ear to another, effects of practice on detecting information in

unattended ear

Evidence for late selection - ✔✔selection of stimuli for final processing may

not occur until after information has been analyzed for meaning, McKay

(1973)

McKay (1973) - ✔✔in attending ear, participants heard biasing words, at

test participants had to choose which was closest to the meaning of

attended to message, results: meaning of the biasing word affected

participants' choice, were unaware of the presentation of the biasing words

Treisman's Attenuation Theory: intermediate-selection model - ✔✔attended

message can be separated from unattended message early in the

information-processing system, selection can also occur later

Treisman's Attenuation Theory: attenuator - ✔✔analyzes incoming

messages in terms of physical characteristics, language, and meaning,

attended message is let through the attenuator at full strength, unattended

message is let through at a much weaker strength

Treisman's Attenuation Theory: dictionary unit - ✔✔contains words, each of

which have thresholds for being activated, words that are common or

important have low thresholds, uncommon words have high thresholds

Divided attention - ✔✔enables people to simultaneously do two things that

were difficult at first, Spelke et al, Schneider and Shiffrin

Spelke et al. - ✔✔after hours of practice, participants could read and

categorize dictated words
