==Broadbent's Filter Model==

==Broadbent's Filter Model==

British researcher [[Donald Broadbent]] was the first researcher to present a hypothesis as to how attention would occur, and how one can focus on specific events. Broadbent’s filter model proposes that the mind blocks out information irrelevant to what one is focusing on, such as, say, ignoring another conversation going on at the same time.[http://www.csun.edu/~vcpsy00h/students/arousal.htm] This idea has received criticism owing to the following situation. Assume that you are at a party, engrossed in conversation with another partygoer, and you hear your name on the side. By all likelyhood, your attention would be diverted, which contridicts Broadbent's theory.

==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]]s. 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.
