|Description:||Philip Carr's note
actually raises a few interesting questions:
If one adopts a computational theory of mind, how can one avoid postulating
I fully agree with that. If, as assumed , e.g., in the Minimalist Program
(Chomsky 1995) syntax is considered an optimal solution to interface
conditions (i.e. constraints imposed by the Conceptual-Intentional and the
Articulatory-Perceptual systems), then all postulated syntactic
steps are interpreted as mental processes/operations.
Now, I'm a theoretical linguist and would gladly be corrected by psycho-
and neurolinguists, but the way I see it, we nevertheless have the same
problems as in the 1960s/1970s:
1. How can we measure the number/complexity of mental processes?
Philip Carr mentions the ill-fated Derivational Theory of Complexity
(DCT) which assumed that postulated analyses were taken to be analyses of
on-line mental operations . As Fodor et al (1974) showed, experimental data
seemed to undermine the DCT.
One problem, e.g., was that sentences apparently involving more
transformations sometimes turned out to be easier to process: in the
Standard Theory adjectives in a pre-modifier function such as 'the
small cat' were sometimes supposed to be derived from underlying relative
clauses, i.e. the cat which is small (cf. Fodor et al 1974: 327).
Note first of all, that a lot of the sentences considered more complex in
the Standard Theory would receive a much simpler Minimalist analysis
(direct merger of Adj in pre-modifier position, no underlying relative
clause). So I think looking at the results of the 1960s/1970s experiments
and reinterpreting from a Minimalist perspective might actually yield a few
interesting results. [For the Minimalist junkies out there: this might not
be easy as I first thought. Chomsky (2000) e.g. claims that long-distance
AGREE is simpler than MOVE, which actually is COPY+MERGE+AGREE. If we just
look at syntax this might suggest that AGREE should be less complex than
MOVE. Yet, I wonder whether long-distance AGREE isn t more complex for LF
since it involves another PROBE-GOAL search whereas identifying copies of
moved elements might be easier.]
However, another point is that the human parser might use non-grammar
information in addition to grammar, i.e. some kind of heuristic principle
(cf. Fodor et al 1974; and as far as I know there are still enough
psycholinguists out there subscribing to this hypothesis but feel free to
correct me if I'm wrong). So is there a parser that doesn't just
use grammatical info and if so, how can we disambiguate the influence of
2. What are the predictions towards grammatical complexity and mental work
load in other theories?
Take e.g. the latest grammatical theory:
Construction Grammar (cf. Fillmore and Kay 1999; Goldberg 2003). In
Fillmore and Kay's (1999; also in Goldberg's 2003) version of Construction
Grammar a sentence can also be the combination/parallel activation of a
number of constructions.
So Goldberg, e.g., considers 'What did Liza buy the child' to consist of 6
types of constructions: 1)the six lexical items, 2) the ditransitive
constructions, 3) the question construction, 4) the Subj-Aux inversion
construction, 5) the VP construction and 6) three NP construction (2003:
Has anyone ever thought about testing whether an increased number of
constructions leads to greater computational work load?
3. And what about neuronal activity? As far as I can see a lot of the 1960
s/1970s studies showed that allegedly higher complexity didn't result in
prolonged comprehension time. But what about increased neuronal activity?
Has anyone so far carried out an fMRI (functional magnetic resonance
imaging) study on increased neuronal network activation as an effect of
syntactic complexity? And if so, do these studies also contrast production
and processing of sentences?
