Testing nesting: A bibliography on the effect of self-embedding and
centre- embedding on ease of processing.

This bibliography reflects the joint efforts of various members of the
Linguist network (listed below) and arises out of a query that I
posted in early December 95.

I asked for information about *empirical* work on centre-embedding
examples like (1).

(1) The dog the stick the fire burned beat bit the cat.
         N1       N2       N3    V3    V2   V1

TERMINOLOGY

I deliberately used the term `centre-embedding' as the term which
other people have applied, but I should of course have called it
`self-embedding'.  In the following I shall try to distinguish the
two, as CE for `centre- embedded sentence' and SE for `self-embedded
sentence', though I don't actually think either concept is at all
clear. Some people use `nesting' instead of `centre-embedding'.  The
clearest examples of unprocessable SEs are of one very specific type,
like (1): object-relative inside object-relative modifying the first
noun, i.e.  abstractly `N1 N2 N3 V3 V2 V1'.

CHOICE EXAMPLES

Though I asked for publications, some people very kindly supplied
relevant raw data as well:

  English: "The claim that the link between convection heating and the
time and energy which can be saved by baking biscuits in a convection
oven rather than a conventional oven is not obvious at first sight is
undoubtedly true."  (Annabel Cormack)

  Classical Greek: "Ancient Greek did possessor constructions with
  center-embedding as the unmarked case:
    [teen [tou prosoopou] phusin]
    the   the    face     nature
    'the nature of the face' (Plato, Politicus 257d)

  This happened even with two possessors (!!):

    [to  [tees  [tou   ksainontos]  tekhnees] ergon]
    the  the    the    wool-carder    art     work
    'the work of the art of the wool-carder'        (Plato, Politicus 281a)

    [ta   [tees   [toon polloon]  psykhees]   ommata]
    the   the     the    many      souls      eyes
    'the eys of the souls of the many'   (Plato, Sophist 254a)

    The data is to appear in my article `Syntax outranks phonology'
    (Phonology 12.3), which, however, has little to do with
    center-embedding.  The data given here are just cannon-fodder in a
    paper on the syntax-phonology interface." (Chris Golston)

This is presented chronologically, in the hope of giving some
impression of the lean years of the 70s and 80s. I haven't seen all
these references yet, so the comments should all be taken with a pinch
of salt.

  Various experiments in which Ss read a SE and judged its
grammaticality, paraphrased it, or repeated it. Results showed that
embedding as such causes difficulty *only* where the meaning is
unhelpful, suggesting that we may not use a push-down store to keep
track of word order, but just follow meaning in linking verbs and
nouns.

  CEs are harder with SEE or LIKE as their embedded verb than with
  e.g. HIT or SLAP, because of the ambiguous subcategorisation.

  "If I provided context in which the constituent propositions are
separately stated antecedents, as in a story, then some naive
listeners understood such sentences [as (1)] at least some of the
time. (Some listeners seemed to balk on them no matter what.)

         Then the fire began to burn the stick.
         The stick jumped out of the fire and beat the dog.
         The dog turned and bit the cat.

        The dog the stick the fire burned beat bit the cat.

  My difficulty was how to produce the twice-embedded sentence with
  appropriate intonation. And this appears to me to provide a simple
  explanation for the difficulty understanding it.
    [.... examples omitted]
  One generally singles out one thing at a time--that is indeed the
  nature of the act of singling something out.

  The fact that some [SEs] are easier to understand, and the things
  that make them easier to understand, put that presumption [that the
  syntax is unprocessable] in serious question."

  "Each of these studies has a number of conditions testing a bunch of
   possible theories. We have found some quite interesting things:
   different in a number of ways from what was predicted by every theory
   that I know (including what was in my thesis)." (Ted Gibson)

  "I've done some psycholinguistic and PET studies investigating the
  processing of single center-embedded sentences.  The upshot of these
  studies are that subjects find even single center embedded sentences harder
  to process than right-branching sentences."  NB CE, not SE, but still
  relevant! Stromswold is karin at ruccs.rutgers.edu. The abstract follows:

  Positron Emission Tomography (PET) was used to determine regional
 cerebral blood flow (rCBF) when 8 normal right-handed males read and
 made acceptability judgments about sentences.  rCBF was greater in
 Broca's area (particularly in the pars opercularis) when subjects
 judged the semantic plausibility of syntactically more-complex
 sentences as compared to syntactically less-complex sentences.  rCBF
 was greater in left perisylvian language areas when subjects had to
 decide whether sentences were semantically plausible than when
 subjects had to decide whether syntactically identical sentences
 contained a nonsense word.  The results of this experiment suggest
 that overall sentence processing occurs in regions of left perisylvian
 association cortex.  The results also provide evidence that one
 particular aspect of sentence processing (the process that corresponds
 to the greater difficulty of comprehending center-embedded than
 right-branching relative clause sentences) is centered in the pars
 opercularis of Broca's area.  Although it is impossible to ascertain
 with certainty what this process is, it is likely to be related to the
 greater memory load associated with processing center-embedded
 sentences.
