One of the weak points of the present critics of AI is their lack of an alternative cognitive theory. In the paper the outline of such a theory is sketched, based on (one reading) of Piaget's genetic epistemology. This is used to clarify the ambiguity of the terms 'symbol' and 'representation', thereby making it possible to suggest a reconciliation of the positions of the critics and defenders ...

Mythili Menon and Roumyana Pancheva; University of Southern California We provide evidence for the ambiguity in color terms (e.g., green) between a gradable and nongradable reading, as proposed in [5]. The evidence comes from color terms in Malayalam. Expressions for color exhibit different morphosyntactic behavior in attributive and predicative positions, and in comparatives, as opposed to oth...

We report the results of one acceptability rating study and two self-paced reading studies on form-meaning mismatch in interpretation past-under-past complement clauses English. Across three experiments, we find an off-line on-line preference for backward-shifted interpretation, line with predictions structural approach to ambiguity when assuming a processing morphological transparent interpret...

We propose a formal system for representing the available readings of sentences displaying quan-tifier scope ambiguity, in which partial scopes may be expressed. We show that using a theory of scope availability based upon the function-argument structure of a sentence allows a deter-ministic, polynomial time test for the availability of a reading, while solving the same problem within theories ...

In this paper I argue that the ‘ambiguity’ between mention-all and mentionsome readings of questions can be resolved when we relate it to the decision problem of the questioner. By relating questions to decision problems, I (i) show how we can measure the utilities of both mention-all and mention-some readings of questions, and (ii) give a natural explanation under which circumstances the menti...
