Michael Kubovy

Michael Kubovy (born 1940) is an Israeli American psychologist known for his work on the psychology of perception and psychology of art.

His writings and research of visual and auditory perceptual organization helped to rekindle interest in the Gestalt School of Psychology in the late 20th century: a "rebirth" of Gestalt Psychology.

He served in the IDF and in 1967, when the Six-Days War broke out, while he was a graduate student, he fought with the "Jerusalem Brigade" (composed of Jerusalem residents, including many students and faculty from the Hebrew University of Jerusalem) in Tourgeman House at the border crossing between Israel and Jordan known as "Mandelbaum Gate."

He earned his Master's degree under Daniel Kahneman (1968) and his doctoral degree under Amos Tversky (1972), both in psychology and both from the Hebrew University of Jerusalem.

The doctoral dissertation was titled Normative and Informational Aspects of Social Influence (1971).

Kubovy began his academic career at University of Illinois Urbana-Champaign in 1971, first as a postdoctoral researcher (advised by Emanuel Donchin) investigating human information processing by means of electroencephalography, and then as Visiting Assistant Professor (1972-1973).

He later served as Assistant Professor and Associate Professor at Yale University (1973-1979) and as Associate Professor and Professor at Rutgers University–New Brunswick (1980-1987).

In collaboration with the cognitive scientist James E. Cutting and the scientific programmer R. M. McGuire, Kubovy invented an auditory analog of the random-dot stereogram (Kubovy et al., 1974).

The striking stimulus was created "by presenting eight simultaneous and continuous sine waves to both ears and by either phase-shifting or frequency-shifting one of them relative to its counterpart in the opposite ear. Particular tones were shifted in sequence such that a melody was heard which was undetectable by either ear alone."

An application to echoic memory soon followed (Kubovy & Howard, 1976).

In November 1977, Kubovy and the psychologist James R. Pomerantz organized a two-day symposium under the auspices of the Psychonomic Society.

At the preceding meeting of the Society, they observed "cognitive psychologists' desire for a phenomenological and intellectual interaction with Gestalt psychology."

Kubovy and Pomerantz later noted that "our colleagues mentioned Gestalt as some might praise a novel like Lolita: with faint embarrassment, brought on by concern that one's audience might think one enjoyed it for the wrong reasons."The participants—who included Fred Attneave, Irving Biederman, Albert Bregman, Norma Graham, Julian Hochberg, Béla Julesz, Daniel Kahneman, Roger Shepard, and Michael Turvey, among others—agreed to contribute to a subsequent volume in which they would "convey the speculative and metatheoretical ground of their research" in the Gestalt tradition, in addition to "the solid data and carefully wrought theories that are the figure of their research."

An important outcome of this work was the finding that action consequences are underweighted (Healy & Kubovy, 1978; 1981), which means "in signal detection terms, [that] this result is consistent with empirically measured criterion shifts being closer to neutral than would be expected from an ideal observer model link. This work was summarized in Kubovy & Healy (1980).

This is reflected in publication of the edited collection Perceptual Organization (1981).

However, this work did lead to the theory of indispensable attributes (Kubovy, 1981).

Published as Perceptual Organization (1981), the volume was introduced by Kubovy and Pomerantz: "Perceptual organization has been synonymous with Gestalt psychology, and Gestalt psychology has fallen into disrepute. In the heyday of Behaviorism, the few cognitive psychologists of the time pursued Gestalt phenomena. But today, Cognitive Psychology is married to Information Processing. (Some would say that it was a marriage of convenience.) After the wedding, Cognitive Psychology has come to look like a theoretically wrinkled Behaviorism; very few of the mainstream topics of Cognitive Psychology make explicit contact with Gestalt phenomena. In the background, Cognition's first love—Gestalt—is pining to regain favor."The book (reprinted by Routledge in 2017 ) was pivotal to Gestalt phenomena entering the mainstream of psychological science.

In subsequent years, Kubovy led multiple studies of perceptual organization, building the foundation for a new area of perceptual research.

Much of this work concentrated on developing new methodologies that allow one "to explore perceptual organization more rigorously than had hitherto been possible. These methodologies rely on the spontaneity and the multistability of grouping while taking care to minimize the effects of whatever voluntary control observers might have over what they see."

Then followed a decade of attempts to show that pitch was as much a carrier of "form" in auditory perception (Kubovy & Daniel, 1983).

As the latter shows the results were there, but were heterogeneous, perhaps even disappointing.

His book The Psychology of Perspective and Renaissance Art (1986) introduced the concept of "the robustness of perspective" and helped to bridge the disciplines of perceptual psychology, art history, and art criticism.

Michael Kubovy grew up in Israel, Czechoslovakia, and Argentina (because his father was an Israeli senior diplomat ).

Kubovy's book The Psychology of Perspective and Renaissance Art was published in 1986 by Cambridge University Press (paperback in 1988).

The book "recounts the lively history of the invention of perspective in the fifteenth century, and shows how, as soon as the invention spread, it was used to achieve subtle and fascinating aesthetic effects."

He was appointed Professor of Psychology at the University of Virginia in 1987, where he taught and directed a research laboratory in the Area of Cognitive Psychology for nearly 30 years, pursuing questions "in visual and auditory perception, cognition, psychology of visual art and music, the nature of pleasure, the philosophy of mind and the phenomenology of experience," conducting experiments with human observers, analyzing "visual and auditory patterns" and proposing "mathematical/statistical models of the data."

In his early work on statistical decision making, Kubovy studied the role of expected utility in perceptual decision making.

This wide-ranging study combines art historical observations, appeal to experimental psychology and concern with the philosophical literature in a text which is at once erudite and not needlessly difficult to read."The book was translated into several languages, including Italian (as La freccia nell'occhio in 1992) and Spanish (as Psicología de la perspectiva y el arte del Renacimiento in 1996). The title of the Italian translation (which means "The arrow in the eye") reflects Kubovy's original choice of the book title, disfavored by the English publisher.

These studies include, among others: Kubovy (1994), Kubovy & Wagemans (1995), Bertamini et al. (1997), Kubovy et al. (1998), Gepshtein & Kubovy (2000; 2005; 2007), Strother & Kubovy (2006), and Kubovy & Van Den Berg (2008).

It is here that Kubovy introduced the influential concept of "the robustness of perspective, later summarized by Yang & Kubovy (1999) as follows: "Viewed from the center of projection, a perspective picture presents the pictorial depth information of a scene.

Knowing the center of projection, one can reconstruct the depicted scene.

Assuming another viewpoint is the center of projection will cause one to reconstruct a transformed scene.

Despite these transformations, we appreciate pictures from other viewpoints."Kubovy also argued against the influential claim advanced by Nelson Goodman (in Languages of Art) that all visual experience (including perception of perspectival representations) was merely a convention. In his polemic against Goodman's notion that geometric rules of pictorial representation are established by consensus, Kubovy argued that"geometry does not rule supreme in the Land of Perspective [...] In fact, if in the Land of Perspective geometry plays a role analogous to the role played by Congress in the United States, then perception has the function of the Constitution.

Whatever is prescribed by the geometry of central projection is tested against its acceptability to perception.

If a law is unconstitutional, it is rejected and must be rewritten to accord with perception.

(p. 125)"The book received multiple accolades, described by Ernst Gombrich as "excellent," and by Samuel Egerton, Jr. as a volume "full of tantalizing observations which students of word and image will find endlessly applicable." The American philosopher and cultural critic David Carrier of Carnegie Mellon University summarized Kubovy's work as follows:"This clearly written, well illustrated book provides the best introduction I have read to the central problems [of perspective].

Starting with a highly original interpretation of Mantegna's Archers Shooting at Saint Christopher in which, Kubovy argues, the arrow entering the eye of the watching king is a metaphor for the art of perspective, he offers an account of Brunelleschi's pioneering experimentation with perspective, trompe l'oeil baroque ceilings, the effects of seeing perspectival pictures from 'off-center' positions, the highly complex perspective of Leonardo's Last Supper, and critique of Nelson Goodman's claim that perspective is merely a convention.

The melody embedded in the tonal arrays was the tune "Daisy Bell," selected for this recording because it was the first song performed by means of computer speech synthesis (used for the same reason in Stanley Kubrick's film 2001: A Space Odyssey, 1968).

The melody was called "cyclotean" by analogy to the "cyclopean image" in the perception of random-dot stereograms.

Over the years this led to two further developments summarized in two widely-cited overview articles (Kubovy & Van Valkenburg, 2001; Kubovy & Schutz, 2010).
