==Treisman's Attenuation Model==

==Treisman's Attenuation Model==

Triesman's attenuation model is a similar theory to that of Broadbent, but it has one exception. Rather than completly blocking "irrelevant" information, Triesman proposes that the mind merely reduces the scale of the information. This attenuation is similar to having water running through two [[faucet|faucets]]. Triesman proposes that one conversation in the party example would be like having one faucet completly open (the primary conversation) and your name being the second faucet (you receive it, but you miss the rest of the conversation.) In a nutshell, this theory states that the mind does not block other information, but that it instead limits information, and lets through important information.[http://books.google.com/books?id=wGti6_4Qn_QC&pg=PA115&lpg=PA115&dq=Treisman%27s+Attenuation+Model+and+faucet&source=web&ots=wqyBweaV2q&sig=0Fe6UcYVzD4WujNFlK7y6IrnFSo&hl=en&sa=X&oi=book_result&resnum=1&ct=result] Examples of blocked information would be, for example, the word "chair" which, in the party situation, would be irrelevant to your conversation.

==The Deutsch-Norman memory selection model==

==The Deutsch-Norman memory selection model==

Unlike the previous models, the Deutsch-Norman theory states that a second selection process occurs in the procedure of determining what is and what is not irrelevant information.[http://books.google.com/books?id=wGti6_4Qn_QC&pg=PR7&lpg=PR7&dq=Deutsch-Norman+memory+selection+model&source=bl&ots=wqyBwebN2r&sig=iMnT7HzriL0IfDjrgT6IrCGrC-g&hl=en&sa=X&oi=book_result&resnum=2&ct=result#PPA116,M1] In this model, received information is filtered for size, proximity, and other factors that determine how much attention is paid to an object, an example being as follows

<big><big><big>A</big></big></big>    <small><small><small>A</small></small></small>

As per the memory selection model, more attention was paid to the larger A, followed by a close inspection, which noticed the smaller A.
