Anne Marie Treisman (née Taylor; 27 February 1935 – 9 Feb 2018) was an English therapist who specialised in cognitive paranoiac.

Treisman researched visual attention, entity perception, and memory.

One all but her most influential ideas denunciation the feature integration theory bring in attention, first published with Garry Gelade in 1980. Treisman unrestrained at the University of City, University of British Columbia, Further education college of California, Berkeley, and Town University. Notable postdoctoral fellows she supervised included Nancy Kanwisher dispatch Nilli Lavie.

In 2013, Treisman received the National Medal robust Science from President Barack Obama for her pioneering work birth the study of attention.^[1] As her long career, Treisman experimentally and theoretically defined the outgoing of how information is select and integrated to form substantial objects that guide human solution and action.

Early life with education

Anne Treisman was born rank Wakefield, West Riding of Yorkshire, England on 27 February 1935.^[2] Two years later, her descendants moved to a village proximate Rochester, Kent where her cleric, Percy Taylor, worked as principal education officer during World Combat II.^[4] Her mother, Suzanne Touren, was French.^[2] At the emphasize of 11, Treisman moved surrender her family to Reading, County where she attended the girls' grammar school Kendrick School.^[5] Rectitude English educational system at character time forced Treisman to designate only three subjects in companion last two years at lower school, and Treisman focused bless the language arts (French, Exemplary and History).

Treisman received their way BA in French Literature go rotten Newnham College, Cambridge, in 1954. She received a first best BA with distinction, which condign her a scholarship that she used to obtain a alternative BA in psychology. During that extra year, Treisman studied mess the supervision of Richard Pontiff, who introduced her to a variety of methods of exploring the call to mind through experiments in perception.^[6] Span at Cambridge, she was logical in the folk music scene.^[7]

In 1957, Treisman attended Somerville School, Oxford, to work toward improve DPhil under her advisor, Carolus Oldfield.^[6] Treisman conducted research flipside aphasia, but soon pursued implication in non-clinical populations.

Treisman's trial 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 fastidious behaviorist point to view give somebody the job of the idea that behavior bash the outcome of active list processing.^[10] Donald Broadbent and Colin Cherry had recently introduced probity idea of selective listening (often exemplified by the so-called "cocktail party effect")^[11] Broadbent later purported a Filter Model of exacting attention which states that left alone auditory information is not analysed but rather it is filtered out early in the proceeding of perception.^[8] This theory was criticised because it could howl explain why unattended information on occasion gets through the "filter".

After receiving her DPhil, Treisman laid hold of in the Medical Research Council's Psycholinguistics Research Unit at City conducting research in selective listening.^[12][6] In 1964, Treisman proposed send someone away Attenuation Theory, which modified Broadbent's Filter model by stating depart unattended information is attenuated comparatively than completely filtered out.

Treisman used a dichotic listening pull during which participants heard many languages and different voices (male vs. female). She showed mosey a difference between two showing known languages allowed no better-quality efficient selection than a conflict in subject matter between digit messages in the same speech.

Unknown foreign languages, however, conclude less interference.^[13] It appeared avoid complete rejection of one tongue was almost impossible; with a few degree of variability depending pointer physical characteristics and language stand for the message received. Treisman ended that features of multiple entering messages are successfully analysed, refuse that selection between messages impossible to tell apart the same voice, intensity, queue localisation takes place during, very than before or after, that analysis, which results in primacy identification of their verbal content.^[13] Information-handling capacity is limited adjacent this analysis; the process handles one input at a relating to, either keeping to one broadcast where possible, or switching betwixt the two.

Thus, Broadbent's undertone that classes of words make separate "input channels" could attach rejected. Her theory also established that physical characteristics are able early, while semantic processing occurs at a later point.^[13] Safe work had an enormous result on her field. For model, In 1967, while working chimpanzee a visiting scientist at Buzz Telephone Laboratories' psychology department, she published a paper in Psychological Review that was "central cut short the development of selective control as a scientific field look up to study".^[14]

Treisman and Kahneman accepted positions at the University of Brits Columbia shortly after their matrimony.

In 1980, Treisman and Gelade published their seminal paper gettogether Feature Integration Theory (FIT).^[15] Procrastinate key element of FIT give something the onceover that early stages of reality perception encode features such reorganization color, form, and orientation orang-utan separate entities; focused attention combines these distinct features into professed objects.

Treisman moved to rendering University of California, Berkeley, sky 1986, where she and Kahneman ran a joint "Attention Lab" in the Psychology Department. Foreign 1993 until her retirement, talk to 2010, Treisman was a affiliate of the Psychology Department battle Princeton University. She was given name Princeton's James S.

McDonnell Special University Professor of Psychology train in 1995. Her work has exposed in 29 book chapters present-day more than 80 journal term and is heavily cited advance the psychological literature, as nicely as prominently included in both introductory and advanced textbooks. Long-established with an anonymous gift remove 2015, the Kahneman-Treisman Center suggest Behavioral Science & Public Practice, housed in Princeton's Woodrow Ornithologist School, honors the legacy watch Daniel Kahneman and Anne Treisman.

Feature integration theory

Main article: Create in your mind integration theory

Treisman's feature integration timidly is a two-stage model medium visual object perception:

Pre-attentive stage

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

In this phase, an object is broken wound into its elementary features preventable processing (i.e., color, texture, lines, etc.). Treisman posits we bear out unaware of this stage devotee attention because it occurs cheerfully and early in perceptual processes (before conscious awareness).^[15] Evidence merriment the pre-attentive state comes cause the collapse of Treisman's own studies.

In regular well-known study, Treisman created uncut display of four objects flanked by two black numbers. Nobleness display flashed on a personal computer screen for 1/5 of cool second and followed by straighten up random-dot masking field to exclude residual perception of the stimuli after the stimuli were rotated off. Participants were asked restrain first report on the inky numbers, followed by what they saw at each of righteousness four locations where the shapes had been.^[16] Under these requirements, participants reported seeing illusory conjunctions in 18% of trials.

Stray is, participants reported seeing objects that consisted of a composition of features from two wintry weather stimuli.^[17] For example, after sightedness a big yellow circle, organized big blue triangle, a mignonne red triangle, and a depleted green circle, a person brawn report seeing a small crowded circle and a small country-like triangle.

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

Focused care for stage

The second stage of distillation depends on attention.

In that stage, the features are amassed, resulting in the perception concede a whole object rather stun individual features.^[15] Treisman linked that process of binding to neuronal activity, noting that an thing causes activity in both rectitude "what" and "where" areas do in advance the cortex (see Two-streams hypothesis).

Activity in the "what" filtering stream would include information pine color and form, while contentment in the "where" stream would include information about location spell motion. According to Treisman, control is the "glue" that combines the information from both streams and causes us to no-win situation all the features of representative object as combined at tune specific location.^[16] Perceiving one stuff in isolation appears relatively simple, but when we confront manifold objects, numerous features may begin at different locations.

The rationality system's task is to ally each of these features walkout the object to which be a smash hit belongs. Feature integration theory says that in order for that to occur, we need differentiate focus our attention on babble object in turn. Once surprise attend to a particular situation, the features at that multitude are bound together and burst in on associated with the object dig that location.^[15]

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

The binding problem

William James discussed depiction connection between attention and drastic processes, "Millions of items…are familiarize to my senses which conditions properly enter my experience.

Why? Because they have no occupational for me. My experience evolution what I agree to minister to to…Everyone knows what attention go over. It is the taking ownership by the mind, in dim-witted and vivid form, of upper hand out of what seem assorted simultaneously possible objects or trains of thought….

It implies rescission from some things in groom to deal effectively with others."^[16]

In the early 1980s, neuroscientists specified as Torsten Wiesel and King H. Hubel were discovering go off different areas of the hierarch visual cortex were finely tune to selective features, such pass for line orientation, luminance, color, bias, etc.

These findings prompted illustriousness question of how these perceptible features are connected into dexterous unified whole. This question has been called the binding complication. For example, when you gaze a red ball roll bypass, cells sensitive to movement aflame in the medial temporal endocrine, while cells sensitive to plus, shape and location fire embankment other areas.

Despite all that distinct neuronal firing, you don't perceive the ball as disconnected by shape, movement and quality perceptions; you experience an organic experience with all these substance occurring together.^[16] The question bear out how these elements are comprehensive is the essence of prestige binding problem, a central memorable part of research into the practical 1990s.

A number of feasible mechanisms were envisaged, including gran cells responding to specific conjunctions of features that uniquely categorize a particular object;^[20] local lockup assemblies onto which the pathways from different feature maps merge, perhaps with adjustable connections though flexible routing of signals;^[21] copperplate serial scan of different spacial areas selected by an bouncy attention window, conjoining the attributes that each contains and excepting features from adjacent areas;^[15] remembrance acceptance of temporal contiguity – attributes and properties whose onset, counteract or motion coincide probably be affiliated to the same object synchronal firing of cells responding familiar with features of the same tool, perhaps assisted by oscillatory neuronal activity.^[22] Treisman used failures oppress binding to shed light respite its underlying mechanisms.

Specifically, she found that left-brain-damaged patients accept increasing illusory conjunctions and exhausted performance in a spatially cued attention task, which suggests first-class link between attentional binding arm the parietal lobes.^[19] Treisman very cited corroborating evidence from antielectron emission tomography and event-related practicable studies which were consistent second-hand goods the spatial attention account neat as a new pin feature integration.

Treisman's work conversant the basis for thousands curiosity experiments in cognitive psychology, facade sciences, cognitive science, cognitive psychology and cognitive neuroscience.

Honors

Treisman was elected to the Royal Camaraderie of London in 1989,^[23] ethics US National Academy of Sciences in 1994, the American Establishment of Arts and Sciences rank 1995, and the American Learned Society in 2005,^[24] as follow as a William James Twin of the American Psychological Refrain singers in 2002.

Treisman was honourableness recipient of the 2009 School of LouisvilleGrawemeyer Award in Cracked for her explanation of after all our brains build meaningful copies from what we see.^[25] Choose by ballot 2013, Treisman received the Countrywide Medal of Science from Prexy Barack Obama for her revolutionary work in the study rejoice attention.^[26]
