Linguistic relativity and the color naming debate

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The concept of Linguistic relativity concerns the relationship between language and thought, about whether and how language influences thought. This question has led to research in multiple disciplines—especially anthropology, cognitive science, linguistics, and philosophy. Among the most popular and controversial theories in this area of scholarly work is the theory of linguistic relativity (also known as the Sapir–Whorf hypothesis). An often-cited "strong version" of the claim, first given by Lenneberg in 1953 proposes that language structure in some way determines how we perceive the world. A "weaker version" of this claim posits that language structure influences the world view of speakers of a given language, but does not determine it.[1]

There are two formal sides to the color debate, the universalist and the relativist. The universalist side claims that our biology is all the same, so color terminology development has absolute universal constraints—while the relativist side claims that the variability of color terms cross-linguistically points to more culture-specific phenomena. Because color exhibits both biological and linguistic aspects, it has become a deeply studied domain that addresses the linguistic relativity question between language and thought.[2]

The color debate was made popular in large part due to Brent Berlin and Paul Kay’s famous 1969 study and their subsequent publishing of Basic Color Terms: Their Universality and Evolution.[3] Although most of the work on color terminology has been done since Berlin & Kay’s famous study, other research predates it, including the mid-nineteenth century work of William Ewart Gladstone and Lazarus Geiger, which also predates the Sapir–Whorf hypothesis, as well as the work of Eric Lenneberg & Roger Brown in 1950s and 1960s.

Universalist view[edit]

Berlin and Kay[edit]

The universalist theory that color cognition is an innate, physiological process rather than a cultural one was started in 1969 by Brent Berlin and Paul Kay in the study detailed in their book Basic Color Terms: Their Universality and Evolution.[3] The study was intended to challenge formerly prevailing theory of linguistic relativity set forth by chief linguistic figures Edward Sapir and Benjamin Lee Whorf in the Sapir–Whorf Hypothesis. They found universal restrictions on the number of basic color terms (BCTs) a language can have, and the ways the language can use these terms. The study included data collected from speakers of twenty different languages from a number of different language families. Berlin and Kay identified eleven possible basic color categories: white, black, red, green, yellow, blue, brown, purple, pink, orange, and gray. To be considered a basic color category, the term for the color in each language had to meet certain criteria:

  1. It is monomorphemic
  2. It is monolexemic (for example, blue, but not bluish)
  3. Its signification is not included in that of any other color term (for example, crimson is a type of red)
  4. Its application must not be restricted to a narrow class of objects (for example, blonde is restricted to hair, wood)
  5. It must be psychologically salient for informants (for example, "the color of grandma's freezer" is not psychologically salient for all speakers)

In case of doubt, the following "subsidiary criteria" were implemented:

  1. The doubtful form should have the same distributional potential as the previously established basic color terms (for example, you can say reddish but not salmonish)
  2. Color terms that are also the name of an object characteristically having that color are suspect, for example, gold, silver and ash
  3. Recent foreign loan words may be suspect
  4. In cases where lexemic status is difficult to assess, morphological complexity is given some weight as a secondary criterion (for example, red-orange might be questionable)

Berlin and Kay also found that, in languages with fewer than the maximum eleven color categories, the colors found in these languages followed a specific evolutionary pattern. This pattern is as follows:

  1. All languages contain terms for black and white.
  2. If a language contains three terms, then it contains a term for red.
  3. If a language contains four terms, then it contains a term for either green or yellow (but not both).
  4. If a language contains five terms, then it contains terms for both green and yellow.
  5. If a language contains six terms, then it contains a term for blue.
  6. If a language contains seven terms, then it contains a term for brown.
  7. If a language contains eight or more terms, then it contains a term for purple, pink, orange, and/or gray.

In addition to following this evolutionary pattern absolutely, each of the languages studied also selected virtually identical focal hues for each color category present. For example, the term for "red" in each of the languages corresponded to roughly the same shade in the Munsell color system. Consequently, they posited that the cognition, or perception, of each color category is also universal.[3]

Additional universalist arguments[edit]

A later study supporting this universal, physiological theory was done by Kessen, Bornstein, and Weiskopf. In this study, sixteen four-month-old infants were presented with lights of different frequencies corresponding to different colors. The lengths of habituation were measured and found to be longer when the infant was presented with successive hues surrounding a certain focal color than with successive focal colors. Kessen, Bornstein and Weiskopf therefore claim that the ability to perceive the same distinct focal colors is present even in small children.[4]

Research before Berlin and Kay (1969)[edit]

Gladstone and Geiger[edit]

In their paper Language and thought: Which side are you on anyway?, Regier et al. discuss the presence of a universalist perspective on the color debate in the mid nineteenth century.

"In the mid-nineteenth century, various scholars, notably William Gladstone (1858) and Lazarus Geiger (1880), noted that the speakers of ancient written languages did not name colors as precisely and consistently – as they saw it – as the speakers of modern European languages. They proposed a universal evolutionary sequence in which color vocabulary evolves in tandem with an assumed biological evolution of the color sense".[5]

Gladstone was a Homeric scholar and in his writings, notably Studies on Homer and the Homeric Age, expressed that because there was virtually a lack of color terminology in Homeric Greek literature, Greeks could probably not see color as we can today.

" ... that the organ of color and its impressions were but partially developed among the Greeks of the heroic age".[6]

Geiger expanded on Gladstone's ideas by looking at other classic works and hypothesized that man gradually became aware of color over time. He posited the idea that this awareness was connected to the order colors came up in the spectrum, starting with longest wavelengths.[7]

Lenneberg & Roberts[edit]

Lenneberg and Roberts presented their paper The Denotata of Color Terms[8] at the Linguistic Society of America in 1953. In this paper they reported their findings on color recall in Zuni speakers. Zuni has one color term for yellow and orange, and Lenneberg and Roberts' study reported that Zuni speakers encountered greater difficulty in color recall for these colors than English speakers who have available terms to distinguish them. Brown and Lenneberg attributed this effect to the property of codability.

Linguistic codability is the ease with which people can name things and the effects of naming on cognition and behavior.[9]

Brown & Lenneberg[edit]

Brown & Lenneberg published A Study in Language and Cognition[10] in 1954, where they discussed the effect of codability on recognition. In their experiment they used a series of Munsell chips to test color recall and recognition in English speakers. Their findings suggested that the availability of a basic color term in a given language affected the retention of that color in recall testing. Brown & Lenneberg linked their study to Lenneberg & Roberts' 1953 findings on color recall in Zuni speakers.

Relativist view[edit]

Initially, Berlin and Kay's theory received little direct criticism. But in the decades since their 1969 book, a significant scholarly debate has developed surrounding the universalism of color terminology. Many relativists find significant issues with this universalism. Barbara Saunders and John A. Lucy are two scholars who are prominent advocates of the opposing relativist position.

Barbara Saunders[edit]

Barbara Saunders believes that Berlin and Kay's theory of basic color terminology contains several unspoken assumptions and significant flaws in research methodology. Included in these assumptions is an ethnocentric bias based on traditions of Western scientific and philosophical thought. She regards the evolutionary component of Berlin and Kay's theory as "an endorsement of the idea of progress" and references Smart's belief that it is "a Eurocentric narrative that filters everything through the West and its values and exemplifies a universal evolutionary process of modernization."

With regards to Berlin and Kay's research, Saunders criticizes the translation methods used for the color terms they gathered from the 78 languages they had not studied directly. Like many others, she also questions the effectiveness of using the Munsell color system in the elicitation of color terminology and identification of focal hues. She feels that "use of this chart exemplifies one of the mistakes commonly made by the social sciences: that of taking data-sets as defining a (laboratory) phenomenon which supposedly represents the real world", and entails "taking a picture of the world for the word and then claiming that that picture is the concept". Finally, she takes issue with the anomalous cases of color term use that she believes Berlin, Kay and Merrifield disregarded in their work on the World Color Survey for the purpose of purifying their results.[11]

In Saunders' 1997 article with van Brakel, they criticize the amount of weight given to study of physiological color perception as support for the universalism of color terminology. They primarily criticize the idea that there is an autonomous neuro-physiological color pathway, citing a lack of concrete evidence for its existence.[12]

Saunders is also bothered by the overall de-contextualization of color terminology and the failure of universalists to address the limitations of their methodologies. She points out that:[11]

"Ordinary colour talk is used in a variety of ways – for flat coloured surfaces, surfaces of natural objects, patches of paintings, transparent objects, shining objects, the sky, flames, illumination, vapours, volumes, films and so on, all of which interact with overall situation, illumination, edges, textures, patternings and distances, making the concept of sameness of colour inherently indeterminate".

John Lucy[edit]

John A. Lucy's criticisms of Berlin and Kay's theory are similar to those of Saunders and other relativists, primarily focusing on shortcomings in research methodologies and the assumptions that underlie them.

Lucy believes that there are problems with how linguistic analysis has been used to characterize the meanings of color terms across languages. Referential range (what a color term can refer to) and grammatical distribution (how the term can be used) are two dimensions Lucy believes are critical to defining the meaning of a term, both of which "are routinely ignored in research on color terms which focuses primarily on denotational overlap across languages without any consideration of the typical use of the terms or their formal status." He also feels that any attempt to contrast color term systems requires understanding of each individual language and the systems it uses to structure reference.

Lucy also believes that there is significant bias present in the design of Berlin and Kay's research, due to their English-speaking and Western points of view. He thinks the use of the Munsell color system demonstrates their adherence to the ideas that "speech is about labeling accuracy" and that, "Meaning is really about accurate denotation," which he believes, "...both derive directly from the folk understandings of English speakers about how their language works." He refers to Conklin's study of Hanunóo[13] as a demonstration of what a study might reveal about a language's color term system when such bias is not present. He demonstrates that "an 'adequate knowledge' of the system would never have been produced by restricting the stimuli to color chips and the task of labeling". (original emphasis).

In summation, he feels that the approach universalists have taken in researching color term universals sets up a procedure that "...guarantees both their discovery and their form," and that, "It does not really even matter whether the researchers involved are open-minded and consciously willing to recognize relativism as a possible outcome—because the universalist conclusion is guaranteed by their methodological assumptions."[14]

Recent scholarship[edit]

Scholarship on color vision has proceeded in three principal domains within the last twenty years. There have been revisions to the Berlin & Kay hypothesis; in response, there have been continued challenges to that hypothesis; and lastly, the field of vision science has expanded to explore hue categorization at a perceptual level, independent of language-based distinctions, possibly offering compromise in the two polar theories.

Revisions of the Berlin & Kay Hypothesis[edit]

In 1999 Paul Kay and Luisa Maffi published an article entitled Color Appearance and the Emergence and Evolution of Basic Color Lexicons,[15] in which they outline a series of revisions in response to data collected in the World Color Survey (WCS) and to Stephen Levinson and his work on the language Yélî Dnye in Papua New Guinea (see below).[16] While upholding an evolutionary track for the addition of basic color terms to any given lexicon, they outlined a series of three Partition Rules (i.e., superordinate rules that determine the evolution of BCTs [mentioned above]):

  1. Black and White (Bk&W): Distinguish black and white.
  2. Warm and Cool (Wa&C): Distinguish the warm primaries (red and yellow) from the cool primaries (green and blue).
  3. Red: Distinguish red.

The ordering of these rules is reflective of the data of the overwhelming majority of languages studied in the WCS. However, exceptions do exist, as was accounted for by Yélî Dnye and other languages within the WCS. Furthermore, they also propose a 0) rule, one which simply states: partition. Such a rule is necessary to motivate the specification of later basic color terms, namely those that can no longer be brought about by application of rules 1)–3).

With respect to the evolution of color terms within a given lexicon, Kay & Maffi further outlined the possibilities of different trajectories of evolution, though all of those numerically possible are not attested in the World Color Survey. Another significant contribution of this article is a discussion of the Emergence Hypothesis (see below), its relation to Yélî Dnye, and its motivation for the authors' revision of evolutionary trajectories.

Opposition to Berlin & Kay et al.[edit]

Here are three approaches to such critiques:

  1. That brought about by implications within the taxonomic structure of the B&K model (as seen further in Berlin's treatment of ethnobiological systems of classification[17])
  2. That as seen in research in color perception in children and infants
  3. That brought about by specific fieldwork

Anna Wierzbicka and Universals of Visual Semantics[edit]

In an article titled The Semantics of Colour: A New Paradigm,[18] Wierzbicka discusses three main critiques of the Universalist approach:

  1. The inability to prove the existence of true color terms (i.e., those based on variations in hue) in languages that lack a superordinate word for color in their taxonomies
  2. The lack of inquiry into the semantic range of any given language's assumed color naming.
  3. That the Western Universalist tradition "[imposes] on other languages and cultures one's own conceptual grid" and does not reflect " 'the native's point of view'", citing Malinowski in the latter.[19]

With regard to 1), she states that "the basic point ... is that, in many languages, one cannot ask the question, 'What color is it?'" The assumption oscillates between two versions: on one hand she argues that languages with no superordinate word for color simply do not have minimal color terms. On the other hand, she argues that even if one contests the first point (i.e., agree that languages that lack a word for color still have color terms), the fact that one cannot ask the question she posits (above) means that color is not a salient semantic domain in these languages. In the structure of her Natural Semantic Metalanguage,[20] color does not constitute a semantic "primitive", though she argues for many others cross-linguistically. (For more on the NSM related to color terms, see Theoretical Linguistics 29:3.)[21]

Pitchford & Mullen: The developmental acquisition of basic colour terms[edit]

This study[22] compares the evolutionary model of color terms of Berlin & Kay to the acquisition of color terms in children (something which has been thought to lag behind other lexical acquisitions). Their study proceeds to three main questions:

  1. Are color terms acquired late?
  2. Are basic color terms acquired in a fixed developmental order?
  3. What factors may influence the acquisition of basic color terms?

With regard to 1), they find that color terms are not acquired any later than other relevant lexemes to distinguish objects. It had been thought, for example, that since color is not necessarily unique to a given object, and diverse objects are more likely to share common color than a common shape, that color terms lagged behind shape terms in development. This was found not to be the case.

Second, they found no correlation between the order of color term acquisition in children and in languages generally. It was found that gray and brown are learned later in development; there was no preference for the six primary color terms over the remaining three secondary ones. The similarity between the acquisition of these terms in children and in language vocabularies was assumed to be comparable, since even in current notions of the B&K hypothesis the evolutionary order of color terms is thought to be based on universals of neurophysiology. While some studies in neurophysiology have shown greater salience for the basic color terms (and thus correlate their earlier evolutionary status), neurophysiology has not been able to account for such phenomena as intuitive separations of warm and cool colors (the second partition rule posited by Kay [see above] is essential to such early-onset warm/cool distinctions, yet is overridden in language with a yellow/green/blue color term).[15]

Levinson & Yélî Dnye[edit]

Yélî Dnye is a language isolate spoken on Rossel Island (Yela) in Papua New Guinea. Among observations about the class, derivation, usage of and disagreement over color naming words in Yélî Dnye is a critique of the BCT-model's assumption that languages which have not yet fully lexicalized the semantic space of color (as was posited to be universal in the original and subsequent B&K papers [1969[3] &1978[23]]) with the use of all eleven basic color names do so by use of the fewer composite terms that they do possess (by B&K's criteria for Yélî Dnye, three). As Stephen C. Levinson argues using methodology similar to that used by B&K for their initial tests and later for the WCS, there are simply regions of the color spectrum for which Yélî Dnye has no name, and which are not subsumed by larger composite categories, even despite the inventive nature of color terms in Yélî Dnye that fall outside the criteria for "basic" status. Given the fact that such color naming words are extremely inventive, (a "semi-productive" mode of adjectival derivation is the duplication of related nouns), Levinson argues that this is highly detrimental to the BCT-theory, insomuch that Yélî Dnye is "a language where a semantic field of color has not yet jelled", and thus one not open to universal constraint.[16]

As Levinson points out, there is evidence that supports the emergence of BCTs through physical objects and words used to signify simultaneous properties such as lightness. As such, these terms do not cohere as a unique, separable semantic domain denoting hue (see Bornstein for this criterion). Over time, though, and through processes of semantic drift, such a domain can emerge. In response to work by Levinson and Lyons, Kay dubs this perspective the Emergence Hypothesis (EH). (See Levinson's article for a discussion on the co-existing evolutionary tracks for color words if one accepts both B&K's position and the Emergence Hypothesis.) Kay & Maffi (1999) incorporate the EH into their evolutionary track by removing from their model the assumption that languages begin by fully segmenting the color spectrum. This inverts their Partition Principles (see above), namely by placing 1) and 3) over 0) and 2). That is, languages partially segment the space into black, white, and red (i.e., 1) & 3)), and then the assignment to partition (0)) and split warm and cool colors (2)) accommodates the rest of the space. As Kay & Maffi explain, this is essential to explications of Y/G/Bu terms (e.g., Cree), which were previously incompatible with the model. However, this model also introduces the possibility for previously divergent evolutionary paths for color terms, since it is only after the rearrangement and reassignment of the Partition Principles that a language that derived from EH origins joins with a language that originally partitioned the whole of the color spectrum.[15]

Vision science and theoretical compatibility[edit]

Marc Bornstein's essay Hue Categorization and Color Naming: Physics to Sensation to Perception[24] separates an analytical review of vision science and color naming into three sections:

  1. Categorization: and its aids to both perceptual and cognitive functions generally
  2. Color Vision and Hue Categorization
  3. Color Naming (an unarticulated derivative of the first two ideas [see his companion essay Hue Categorization and Color Naming: Cognition to Language to Culture[25] for a further discussion of this point])

As a result, he summarizes both the findings of vision science (as it relates to color naming) and the linking of three separate but causally related processes within the study of color naming phenomena. He states that "the physics of color, the psychophysics of color discrimination, and the psychology of color naming are not isomorphic". The color spectrum clearly exists at a physical level of wavelengths (inter al.), humans cross-linguistically tend to react most saliently to the primary color terms (a primary motive of Bornstein's work and vision science generally [see Pitchford & Mullen above]) as well as select similar exemplars of these primary color terms, and lastly comes the process of linguistic color naming, which adheres both to universal patterns but demonstrates individual uniqueness. While one may have origins in its predecessor, variation among test subjects in vision science and linguistic variation demonstrate that it is not a process of whole causality. In his companion essay,[25] he demonstrates that this process of causality may indeed be reversed, which he explains through a set of "models of development":

  1. Undeveloped
  2. Partially developed
  3. Fully developed

In response, there are three ways that outside experience may affect this development: through (A) induction, (B) modification, or (C) deprivation. Thus the logical possibilities are 1A & 1C; 2A, 2B & 2C; and 3B & 3C. Using this format, he explains that developmental altering in hue categories "entail perceptual 'sharpening' and 'broadening'". He attributes this to either "maturation" (perceptually) or "experience". Such a conclusion is necessarily indeterminate because understanding of why certain hue categories are lost and others induced (cf. developmental processes above) "requires further exacting research". Coming from these two perspectives (i.e., those outlined in the causation above, and the models of development), this leads Bornstein to conclude that "there appear to be nontrivial biological constraints on color categorization [and that] ... the available evidence seems compatible with a position of moderate universality that leads to expectations of probabilistic rather than deterministic cross-cultural correspondence", and that "in color, relativism appears to overlay a universalist foundation".[25]
