| − | Triesman's attenuation model is a similar theory to that of Broadbent, but it has one exception. Rather than completely 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]]s. Triesman proposes that one conversation in the party example would be like having one faucet completely 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. | + | Triesman's attenuation model is a similar theory to that of Broadbent, but it has one exception.
