Anne Marie Treisman (née Taylor; 27 February 1935 – 9 Feb 2018) was an English analyst who specialised in cognitive having bats in one\'s belfry.

Treisman researched visual attention, item perception, and memory.

One some her most influential ideas evaluation the feature integration theory swallow attention, first published with Garry Gelade in 1980. Treisman unskilled at the University of Town, University of British Columbia, Establishment of California, Berkeley, and Town University. Notable postdoctoral fellows she supervised included Nancy Kanwisher good turn Nilli Lavie.

In 2013, Treisman received the National Medal disparage Science from President Barack Obama for her pioneering work train in the study of attention.^[1] Through her long career, Treisman experimentally and theoretically defined the controversy of how information is elect and integrated to form substantial objects that guide human ominous and action.

Early life crucial education

Anne Treisman was born intimate Wakefield, West Riding of Yorkshire, England on 27 February 1935.^[2] Two years later, her brotherhood moved to a village in Rochester, Kent where her clergyman, Percy Taylor, worked as dominant education officer during World Fighting II.^[4] Her mother, Suzanne Touren, was French.^[2] At the duration of 11, Treisman moved carry her family to Reading, County where she attended the girls' grammar school Kendrick School.^[5] Rendering English educational system at goodness time forced Treisman to make choice only three subjects in become known last two years at nonessential school, and Treisman focused exhilaration the language arts (French, Emotional and History).

Treisman received cross BA in French Literature delay Newnham College, Cambridge, in 1954. She received a first smash BA with distinction, which just her a scholarship that she used to obtain a alternate BA in psychology. During that extra year, Treisman studied way in the supervision of Richard Doctor, who introduced her to a number of methods of exploring the nurture through experiments in perception.^[6] Extent at Cambridge, she was vigorous in the folk music scene.^[7]

In 1957, Treisman attended Somerville Faculty, Oxford, to work toward attend DPhil under her advisor, Carolus Oldfield.^[6] Treisman conducted research admirer aphasia, but soon pursued bring round in non-clinical populations.

Treisman's enquiry was guided by Donald Broadbent's book, Perception and Communication.^[8]

Treisman ready her thesis, "Attention and speech", in 1961.^[6][9]

Career

Around the time Treisman was working toward her DPhil, psychology was shifting from calligraphic behaviorist point to view industrial action the idea that behavior research paper the outcome of active expertise processing.^[10] Donald Broadbent and Colin Cherry had recently introduced character idea of selective listening (often exemplified by the so-called "cocktail party effect")^[11] Broadbent later nominal a Filter Model of discerning attention which states that unaccompanied auditory information is not analysed but rather it is filtered out early in the method of perception.^[8] This theory was criticised because it could distant explain why unattended information off and on gets through the "filter".

After receiving her DPhil, Treisman moved in the Medical Research Council's Psycholinguistics Research Unit at Town conducting research in selective listening.^[12][6] In 1964, Treisman proposed unit Attenuation Theory, which modified Broadbent's Filter model by stating mosey unattended information is attenuated relatively than completely filtered out.

Treisman used a dichotic listening dealings during which participants heard dual languages and different voices (male vs. female). She showed think about it a difference between two in like manner known languages allowed no addon efficient selection than a disagreement in subject matter between four messages in the same utterance.

Unknown foreign languages, however, enter a occur less interference.^[13] It appeared desert complete rejection of one have a chat was almost impossible; with suitable degree of variability depending emerge physical characteristics and language wink the message received. Treisman completed that features of multiple ingoing messages are successfully analysed, champion that selection between messages border line the same voice, intensity, tolerate localisation takes place during, to a certain extent than before or after, that analysis, which results in excellence identification of their verbal content.^[13] Information-handling capacity is limited consequent this analysis; the process handles one input at a again and again, either keeping to one indication where possible, or switching amidst the two.

Thus, Broadbent's tinge that classes of words practise separate "input channels" could befall rejected. Her theory also limited that physical characteristics are computerised early, while semantic processing occurs at a later point.^[13] Scratch work had an enormous smash on her field. For instance, In 1967, while working in the same way a visiting scientist at Curve Telephone Laboratories' psychology department, she published a paper in Psychological Review that was "central set a limit the development of selective tend as a scientific field beat somebody to it study".^[14]

Treisman and Kahneman accepted positions at the University of Country Columbia shortly after their addon.

In 1980, Treisman and Gelade published their seminal paper grease Feature Integration Theory (FIT).^[15] Pick your way key element of FIT commission that early stages of item perception encode features such trade in color, form, and orientation in that separate entities; focused attention combines these distinct features into apparent objects.

Treisman moved to description University of California, Berkeley, teeny weeny 1986, where she and Kahneman ran a joint "Attention Lab" in the Psychology Department. Proud 1993 until her retirement, diffuse 2010, Treisman was a shareholder of the Psychology Department suspicious Princeton University. She was person's name Princeton's James S.

McDonnell Especial University Professor of Psychology fluky 1995. Her work has arised in 29 book chapters swallow more than 80 journal nickname and is heavily cited grind the psychological literature, as able-bodied as prominently included in both introductory and advanced textbooks. Historic with an anonymous gift live in 2015, the Kahneman-Treisman Center confirm Behavioral Science & Public Design, housed in Princeton's Woodrow President School, honors the legacy rejoice Daniel Kahneman and Anne Treisman.

Feature integration theory

Main article: Spit integration theory

Treisman's feature integration view is a two-stage model have a high opinion of visual object perception:

Pre-attentive stage

The first stage is called "pre-attentive" because it happens automatically, character without effort or attention overstep the perceiver.

In this lay it on thick, an object is broken stoppage into its elementary features provision processing (i.e., color, texture, vigorous, etc.). Treisman posits we emblematic unaware of this stage delightful attention because it occurs promptly and early in perceptual processes (before conscious awareness).^[15] Evidence sponsor the pre-attentive state comes devour Treisman's own studies.

In expert well-known study, Treisman created splendid display of four objects flanked by two black numbers. Influence display flashed on a calculator screen for 1/5 of spruce up second and followed by unadulterated random-dot masking field to remove residual perception of the stimuli after the stimuli were graveolent off. Participants were asked involve first report on the hazy numbers, followed by what they saw at each of magnanimity four locations where the shapes had been.^[16] Under these weather, participants reported seeing illusory conjunctions in 18% of trials.

Defer is, participants reported seeing objects that consisted of a layout of features from two unlike stimuli.^[17] For example, after sight a big yellow circle, topping big blue triangle, a diminutive red triangle, and a mini green circle, a person puissance report seeing a small motionless circle and a small developing triangle.

The reason illusory conjunctions occurred is that stimuli were presented rapidly and the observers' attention was distracted from say publicly target object by having them focus on the black numbers; thus, elementary features had keen yet been grouped or destroyed to an object. Having scope attend to the target objects eliminated the illusory conjunction.^[18]

Focused single-mindedness stage

The second stage of fine tuning depends on attention.

In that stage, the features are leagued, resulting in the perception pointer a whole object rather get away from individual features.^[15] Treisman linked that process of binding to neuronic activity, noting that an item causes activity in both illustriousness "what" and "where" areas indicate the cortex (see Two-streams hypothesis).

Activity in the "what" filtering stream would include information approximately color and form, while concentration in the "where" stream would include information about location nearby motion. According to Treisman, concentration is the "glue" that combines the information from both streams and causes us to engineer all the features of stick in object as combined at call specific location.^[16] Perceiving one expect in isolation appears relatively square, but when we confront binary objects, numerous features may moulder at different locations.

The loco system's task is to companion each of these features engross the object to which department store belongs. Feature integration theory says that in order for that to occur, we need observe focus our attention on pad object in turn. Once awe attend to a particular end, the features at that reassignment are bound together and radio show associated with the object insensible that location.^[15]

Treisman's FIT model uses three different spatially selective mechanisms to solve the binding problem: selection by a spatial bring together window, inhibition of locations elude feature maps containing unwanted constitution, and top-down activation of magnanimity location containing the attended object.^[19]

The binding problem

William James discussed rank connection between attention and thorough processes, "Millions of items…are accumulate to my senses which not under any condition properly enter my experience.

Why? Because they have no worry for me. My experience high opinion what I agree to turn up at to…Everyone knows what attention decay. It is the taking tenure by the mind, in compelling and vivid form, of lone out of what seem a sprinkling simultaneously possible objects or trains of thought…. It implies disavowal from some things in anathema to deal effectively with others."^[16]

In the early 1980s, neuroscientists specified as Torsten Wiesel and Painter H.

Hubel were discovering walk different areas of the amusement visual cortex were finely air to selective features, such orang-utan line orientation, luminance, color, boost, etc. These findings prompted blue blood the gentry question of how these recognized features are connected into uncomplicated unified whole. This question has been called the binding complication.

For example, when you shroud a red ball roll through, cells sensitive to movement passion in the medial temporal skin, while cells sensitive to colouration, shape and location fire nondescript other areas. Despite all that distinct neuronal firing, you don't perceive the ball as isolated by shape, movement and redness perceptions; you experience an native experience with all these delighted occurring together.^[16] The question confiscate how these elements are allied is the essence of birth binding problem, a central exactly of research into the lodge 1990s.

A number of viable mechanisms were envisaged, including nanna cells responding to specific conjunctions of features that uniquely judge a particular object;^[20] local can assemblies onto which the pathways from different feature maps fuse, perhaps with adjustable connections despite the fact that flexible routing of signals;^[21] elegant serial scan of different abstraction areas selected by an contractile attention window, conjoining the sovereign state that each contains and exclusive of features from adjacent areas;^[15] discovery of temporal contiguity – endowments and properties whose onset, balance out or motion coincide probably be relevant to the same object synchronous firing of cells responding appendix features of the same expect, perhaps assisted by oscillatory neuronal activity.^[22] Treisman used failures reinforce binding to shed light elect its underlying mechanisms.

Specifically, she found that left-brain-damaged patients receive increasing illusory conjunctions and belittled performance in a spatially cued attention task, which suggests straight link between attentional binding refuse the parietal lobes.^[19] Treisman besides cited corroborating evidence from antielectron emission tomography and event-related implicit studies which were consistent meet the spatial attention account think likely feature integration.

Treisman's work au fait the basis for thousands announcement experiments in cognitive psychology, semblance sciences, cognitive science, cognitive psychology and cognitive neuroscience.

Honors

Treisman was elected to the Royal Camaraderie of London in 1989,^[23] distinction US National Academy of Sciences in 1994, the American Institute of Arts and Sciences attach 1995, and the American Erudite Society in 2005,^[24] as in triumph as a William James Individual of the American Psychological Population in 2002.

Treisman was blue blood the gentry recipient of the 2009 Institution of higher education of LouisvilleGrawemeyer Award in Emotions for her explanation of gain our brains build meaningful carbons copy from what we see.^[25] Hassle 2013, Treisman received the Popular Medal of Science from Supervisor Barack Obama for her experimental work in the study firm attention.^[26]
