Jun 11, 2023 · Broadbent wanted to see how people could focus their attention (selectively attend), and to do this; he deliberately overloaded them with stimuli. One of the ways Broadbent achieved this was by simultaneously sending one message to a person’s right ear and a different message to their left ear.
Anne Treisman's feature integration theory (FIT), first proposed in 1980, holds that attention is critical to the formation of bound representations of objects and, by extension, it proposes that attention is critical to our conscious experience of those bound representations.

Colin Cherry noted that no matter how focused you were on one conversation if someone mentioned your name in another... you would be very likely to hear it. He called it the Cocktail Party Effect. A Dichotic Listening Task is when a user listens to two messages in both ears. How, though, can we ensure that the person listening is truly trying to fo...
Donald Broadbent developed the first model for the function of attention. Broadbent theorized that sensory organs took in the information and that the information was then funneled through a "bottleneck" where only a small portion of the overall information reached our working memory. The "Filter" that Broadbent theorized could focus on specific ph...
Interestingly, a student of Broadbent, Anne Treisman, continued his work and attempted to fill the holes in his theory. Sometimes psychologists refer to this model as the "leaky filter model" of attention, and similar to Broadbent's, it is classified as an early-selection process. Treisman said that within the filter of Broadbent's model, there wer...
In 1963, Deutsch and Deutschtheorized a late-selection model, which supposed that all information is selected for meaning analysis. After analyzing the meaning, the brain picks which parts are relevant and focuses on those. We also call this the pertinence model of attention. Deutsch and Deutsch believe you'll process the meaning of the information...
Normantook Deutsch and Deutsch's theory and refined it. One of the problems with Deutsh and Deutsch's theory was that unattended information is lost very quickly. Norman theorized that this is probably because short-term memory lasts only seconds without rehearsal. He found participants could remember the last few words of an unattended message if ...
Donald MacKayperformed some interesting studies on attention, specifically on late-selection models. First, participants were set up with a dichotic listening task. In the ear they were supposed to be paying attention to, they heard ambiguous sentences. "They were throwing stones at the bank." Is it a money bank or a river bank? In the other ear, t...
Later in 1987, two psychologists proposed a "multimode theory," which viewed attention as flexible and meant that we could filter out irrelevant information at any point. However, we are bottlenecked by our own processing ability, capacity, and effort.
Something important to remember is that in 2009, a study showed that lower working memory capacities result in a worse ability to focus. This is important because it shows attention may be tied to intelligence since working memory and intelligence are also closely correlated.
Sep 16, 2019 · I have discussed four subjects central to Anne Treisman’s groundbreaking work: rapid feature search versus slower conjunction search; set summary mean perception; perception in special populations; and depth perception in the face of binocular rivalry.

Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
Oct 20, 2023 · Treisman's Attenuation Model: Proposes that instead of filtering out information thoroughly, we lower the volume on unattended stimuli, thus "attenuating" them. Change Blindness: The failure to notice significant changes in a visual scene. Inattention Blindness: The inability to notice something fully visible because attention is directed ...

Jul 9, 2019 · Bold claims, and broad theoretical perspectives are often held to severe scrutiny. Anne Treisman’s Feature Integration Theory (FIT), proposed in its most famous form in Treisman and Gelade (1980), is a good example of this.
