see, this is the problem with syntax

Here I am, desperately scouring as many textbooks as I can lay my hands on, for tomorrow’s Sentence Processing lecture.

My eye falls on this sentence:

The fireman told the man that he had risked his life for to install a smoke detector.

And I scan the surrounding text for something to do with the “for to V” construction. Maybe the exposition is of the effect of nonstandard syntax on reading times? But that’s got nothing to do with it. It’s a garden path sentence, so you’re not even meant to be able to entertain the “for to V” option, because it’s meant to be an ungrammatical sequence making you reanalyse ([The fireman told [the man that he had risked his life for] to install a smoke detector]).

So, I have reanalysed. But since [The fireman told the man [that [he had risked his life for to install a smoke detector]]] is not “ungrammatical”, the sentence is only ambiguous, not a true garden path. I think.

And this is why phonology is so much better.

speaker as hearer

[Language post]

I’ve been impressed by the boldness of Fernández and Smith Cairns in devoting a chapter to “The Speaker” ahead of the chapter on “The Hearer” in their textbook Fundamentals of Psycholinguistics.

It’s one of the great fundamentals that there isn’t really a good model of how speech production works from a psycholinguistic perspective. The best established and most influential models of speech production certainly deal with linguistic units such as syllables or phonemes, but they don’t go any closer to articulation than that. These units serve as the input to whatever motor processes generate speech movements, but the motor processes themselves are generally treated as quite separate, if not trivial. (Fernández and Smith Cairns’s diagram of speech production has “articulatory system” well outside the box of interesting processes in their diagram at the start of the chapter.) The ‘perception’ side is generally much better understood than the ‘production’ side of things, so tackling production ahead of perception/comprehension is an interesting step.

But more striking – there’s a whole section of the Speaker chapter devoted to Producing Speech After It Is Planned. So might this be a place to find new insights linking mentally represented symbols to articulation? even tentatively, as befitting an introductory text?

Well, no – the section is acoustic, not articulatory. Shame! There’s a head diagram with the articulators labelled, but the diagrams are waveforms and spectrograms, not x-ray pellet tracings or EPG outputs. Not even so much as a diagram of a mass on a spring to help the reader feel warm and fuzzy.

It’s a perfectly fine section on the acoustic properties of consonants and vowels, I should add, but it does make you wonder what they’re going to talk about in the “Hearer” chapter now that all this talk of sine waves and formant transitions is out of the way.

looking back

“Few researchers feel that they have direct access to all of the truth that is worth seeking. Naturally, one looks to one’s contemporaries for help, but unless we hold with particular rigidity to the view that historical development is a matter of monotonically nondecreasing progress, with the present always ipso facto more enlightened than the past, there is no reason not to treat our intellectual ancestors with similar respect.”

parodies

English can allow the word-initial sequence ʃr. English can allow word-final sequences like -lfths. English words can be multisyllabic without being morphologically complex. English prose sentences can conform to highly regular rhythmic patterns.

shred /ʃrɛd/
twelfths /twɛlfθs/
military territory

Three cream scones please – Kate Snow will share Paul’s.
Thirty happy laddies whistled loudly all the way to Portmahomack.
Innocent mineral magazines reappeared yesterday.
Don’t you want a fundamental macaroni explanation?

But these are all rarities – these phonotactic sequences, this morpho/phonological fact, the extended consistency of these rhythmical patterns – they illustrate what is unusual about the forms of English, not what is typical.

So I’m wondering – we can play around with things like these (and a noted psycholinguist and a renowned anglicist are in print with apparently independent and beautifully elaborate manipulations of prose rhythm) and presumably there is something to be learned from the exercise – but what is that something?

“Our understanding of the complex and ‘irregular’ structure of ordinary prose can be sharpened,” says Angus McIntosh, “by exposure to … simple but abnormally iterative structures…” But how? Read this aloud, with a Tum-ti-ti rhythm:

Note, in a triangle having an angle of ninety degrees that the square that is made with its base the hypotenuse equals in area the sum of the squares that are made on the sides which are forming the right angle.

Examples like this show that the rhythms of ordinary prose include the raw materials for artfully constructed ‘abnormal’ structures, but doesn’t that just creatively exaggerate or parody the characteristics of naturally occurring text, rather than also providing much basis for insight into these forms?

segment sceptics

Selected, in chronological order

• Paul (1886), according to Abercrombie (1991): “In contrast to Pike’s view that a stretch of speech has a natural segmentation is the view that it is an indissoluble continuum, with no natural boundaries within it. This view is at least a hundred years old. It is clearly stated, for example, by Hermann Paul in his Principien der Sprachgeschichte in 1886. The word, he says, is ‘eine continuerliche reihe von unendlich vielen lauten,’ ‘a continuous series of infinitely numerous sounds,’ as HA Strong translates it in Principles of the History of Language. … As he puts it, ‘… A word is not a united compound of a definite number of sounds, and alphabetical symbols do no more than bring out certain characteristic points of this series in an imperfect way.’” (Abercrombie 1991: 29-30)

• Twaddell (1935) – the phoneme is “a fiction, defined for the purpose of describing conveniently the phonological relations among the elements of a language, its forms,” p53; “it is meaningless to speak of ‘the third phoneme … of the form sudden’, or to speak of ‘an occurrence of a phoneme’. What occurs is not a phoneme, for the phoneme is defined as the term of a recurrent differential relation. What occurs is a phonetic fraction or a differentiated articulatory complex correlated to a micro-phoneme. A phoneme, accordingly, does not occur; it ‘exists’ in the somewhat peculiar sense of existence that a brother, qua brother, ‘exists’ – as a term of a relation,” p49.

• Firth (1935) – “It is all rather like arranging a baptism before the baby is born. In the end we may have to say that a set of phonemes is a set of letters. If the forms of a language are unambiguously symbolised by a notation scheme of letters and other written signs, then the word ‘phoneme’ may be used to describe a constituent letter-unit of such a notation scheme” (Firth 1957 [1935]: 21)

• Firth (1948) – on using literacy-inspired transcriptions as a basis for phonological analysis (from the 1930s onwards, the writings of JR Firth show him distancing himself from over-reliance on transcriptions in alphabetic notation, for phonological analysis): “The linearity of our written language and the separate letters, words, and sentences into which our lines of print are divided still cause a good deal of confused thinking in due to the hypostatization of the symbols and their successive arrangement. The separateness of what some scholars call a phone or an allophone, and even the ‘separateness’ of the word, must be very carefully scrutinized” (Firth 1957 [1948]: 147).

• Ladefoged (1959) – quoted by Lüdtke (1969: 151): “The ultimate basis for the belief that speech is a sequence of discrete units is the existence of alphabetic writing. This system of analysing speech and reducing it to a convenient visual form has had a considerable influence on western thought about the nature of speech. But it is not the only possible, nor necessarily the most natural, form of segmentation.”

• Lyons (1962), commenting on Firth: “the practical advantages of phonemic description for typing and printing should not of course be allowed to influence the theory of phonological structure. It has been argued that phonemic theory has been built on the ‘hypostatisation’ of letters of the Roman alphabet: cf Firth, [‘Sounds and Prosodies,’ 1948], p134”

• Abercrombie (1965) is quoted by Lüdtke (1969: 151) as saying, “The phoneme … is not something which has a ‘real existence’.”

• Lüdtke (1969) – abstract, “the phoneme segment is not a natural item but a fictitious unit based on alphabetic writing”

• Householder (1971), summarised by Vachek (1989: 25): “[Householder] formulates the question whether, instead of postulating Chomskyan artificial underlying forms, it would not be more realistic to regard the graphical shapes of words as starting points from which the language user obtains their spoken, phonological shapes.”

• Linell (1982) – a whole book providing comprehensive, detailed coverage of the topic, Written Language Bias in Linguistics.

• Kelly and Local (1989) – the question of notation – aim to avoid doing phonetic transcription with the same symbols as are then used for doing phonological transcription/analysis.

• Abercrombie (1991) – “Segment, then, is the name of a fiction. It is a transient moment treated as if it was frozen in time, put together with other segments to form a ‘chain’ rather than a ‘stream’ of speech. Methodologically it is a very useful fiction. A segment, isolated from the flow of speech, can be taken out of its context, moved into other context, given a symbol to represent it, compared with segments from other languages, placed in systems of various sorts, singled out for special treatment in pronunciation teaching; and used in dialectology, speech therapy, the construction of orthographies. (The same is true, of course, of speech-sound and phone. They do not give rise, however, to the possibility of a word for the process, ‘segmentation.’)” (p30)

• Faber (1992) – “segmentation ability, rather than being a necessary precursor to the innovation of alphabetic writing, was a consequence of that innovation” (p112); “segmentation ability as a human skill may have been a direct result of (rather than an impetus to) the Greek development of alphabetic writing. Thus, the existence of alphabetic writing cannot be taken eo ipso as evidence for the cognitive naturalness of the segmentation that it reflects” (p127)

• Derwing (1992) – “the segment (or phoneme) may not be the natural, universal unit of speech segmentation after all, and that the orthographic norms of a given speech community may play a large role in fixing what the appropriate scope is for these discrete, repeated units into which the semi-continuous, infinitely varying physical speech wave is actually broken down.” p200

• Port & Leary (2005) in Language, 81

• Port (2006), ‘The graphical basis of phones and phonemes.’

• Ladefoged (2005) – “We should even consider whether consonants and vowels exist except as devices for writing down words … [they] are largely figments of our good scientific imaginations,” p186; “We also lose out in that our thinking about words and sounds is strongly influenced by writing. We imagine that the letters of the alphabet represent separate sounds instead of being just clever ways of artificially breaking up syllables,” p190; “the division of the syllable into vowels and consonants is not a natural one. Alphabets are scientific inventions, and not statements of real properties of words in our minds. … vowels and consonants are useful for describing the sounds of languages. But they may have no other existence,” p191; “The alphabet, which regards syllables as consisting of separate pieces such as vowels and consonants, … is a clever invention allowing us to write down words, rather than a discovery that words are composed of segment-size sounds,” p198.

• Silverman (2006) – p6, p11-13, and elsewhere.

• Lodge (2007): “There has been a long history of warnings against the notion of the phonological segment (eg Paul 1890, Kruszewski 1883, Baudoin de Courtenay 1927), as pointed out succinctly by Silverman (2006). Later the concept was criticised by Firthian prosodists (see Palmer 1970) and more recently reviewed by Bird & Klein (1990); the most recent exposé of the misguided acceptance of alphabetic segmentation in phonology can be found in Silverman (2006).”

 

language acquisition upside down

One place where the thorny problems of linguistic theory become most obvious and demand the most determined engagement is in the area of child language acquisition. (The other, I think, is language variation and change, unless I just say that because these are what I find the most interesting.)

Take the concept of language structure. The belief that language has structure is, naturally, fundamental to the discipline of linguistics. But it is possible to understand this in radically different ways.

According to Hirsh-Pasek and Golinkoff in their book, Origins of Grammar, theorising about child language is generally done according to one of two broad approaches, which they characterise as “outside-in” versus “inside-out”. “Outside-in” includes social-interactional theories and cognitive theories; “inside-out” includes the various permutations of nativism.

One of these approaches, they say, “contends that language structure exists outside the child, in the environment.” If I didn’t tell you any more, would you be able to say which of the two options – ‘interactionist’ or ‘nativist’ – was being described here?

In fact, HP&G are referring to social-interactional/cognitive theories as believing that language structure exists outside the child (nativist theories rely instead on the innate language-specific knowledge).

Now it is quite possible that some theorists on the interactionist side do believe in language structure as having some sort of real-if-‘abstract’, independent existence. This would betray itself by, for example, the use of terms like “finding” or “discovering” things like “units” (or the boundaries between units) such as segments, morphemes, phrases, clauses in the ambient language. Such interactionists would then share with nativists the view that (spoken) language embodies or comprises real-if-‘abstract’ units organised in a real-if-‘abstract’ structure, and as the job of speakers is to produce speech with these properties, so the job of the listener is to recognise or calculate the identity of the units in what they hear and the relations between these units.

But a much more interesting prospect is the type of ‘interactionist’ approach that does not impute such reality to language structure at all. That is the view that the raw data of spoken language must be clearly distinguished from the analysis which an observer (lay or specialist) might undertake of it. In other words, there is no implicit structure lurking there in speech, whether phonological or syntactic: structures are inferred by analysts and act as handy descriptive/analytical tools, but they’re not really there. It is a serious criticism of some schools of thought that they treat the analysts’ analysis as being in fact what language is composed of – as though analytical constructs such as noun, verb, IP, DP, etc, actually are somehow or somewhere embodied in utterances. It’s one thing to say that when linguists want to get a handle on what people produce/hear they need to identify units and categorise things – these units and categories are convenient as technical descriptions in order that specialists can spot patterns and talk to each other about them. It’s another thing to say that spoken language consists of these units and categories such that the linguist’s task is to discover them (rather than impose them).*

As Joseph et al (2001: 60) put it, “whereas for the psychologistic structuralist speech comes about through implementation of the speaker’s knowledge of a systematic linguistic structure, for Firth the systematic structure is a linguist’s fiction, resulting from the attempt to understand speech.”** Thus (for example) the nativist scours the child’s productions in order to establish which aspects of linguistic structure must have unfolded in their mind by that point – the more interesting varieties of interactionism make use of structure, on paper, in the analysis, only as a tool to understanding what the child understands.

If both sides in the field of language acquisition, the interactionist and the nativist, share the conceptualisation of the linguist’s task as being one of discovering linguistic structure that actually exists out there/in language, then the differences between the two approaches shrink rather dramatically. But when this conceptualisation is not shared, it makes the ‘interactionist’ approach much harder to evaluate on ‘nativist’ terms, for one thing, and more importantly it keeps the idea of “language structure” where it belongs, in the realm of open questions needing discussion. Linguistic descriptions are convenient (-to-the-linguist) if not indispensible ways of categorising bits of utterances, but they have no life of their own.

anybody’s guess

Everyone blames phonological representations for language-related impairments, or deficits in phonology-related tasks like nonsense-word repetition. But what is a phonological representation? What do impaired phonological representations look like? In what specific ways do they differ from unimpaired representations, and how can you tell? What does it all mean?!

Munson (2006) in a commentary on Gathercole’s keynote article in Applied Psycholinguistics expatiates thus, and I can only concur:

Although there are many different perspectives on the factors that drive nonword repetition performance, we can all agree that the relationship between nonword repetition and word learning is due to the association of these constructs with phonological representations. The relevant question to ask, then, concerns the nature of phonological representations themselves. What are they? Textbook descriptions of these generally posit that they look something like the strings of symbols that we are taught to transcribe in phonetics classes. However, phonetic transcriptions, even narrow ones, are abstractions of the signals that are being transcribed. The level of detail that they code is ultimately related more to the perceptual abilities of the listener, the degrees of freedom in the symbol system, and a priori assumptions about the quantity of detail that is relevant for transcription than to the signal being transcribed and its associated phonological representation.

What, then, do “real” phonological representations encompass? What is being represented? The answer to that is anyone’s best guess. Representations themselves are latent variables. We can never see them, we can only posit them as explanations for the sensitivity that people have to variation and consistency in the speech signal in different tasks. (p578)

A welcome reality check in perhaps a slightly unexpected place, even though, of course, it still doesn’t solve the fundamental problem. Everybody’s preferred solution for testing the true nature of implicit phonological representations is different, and inadequate to different degrees and in different ways, but in the nature of the concept of phonological representations itself, that is simply how it has to be.
