W. Labov's & T. Labov's findings concerning their child grammar acquisition ("Learning the Syntax of Questions" in Recent Advances in the Psychology of Language, Campbell, R. & Smith, P. Eds, New York: Plenum Press, 1978) are interpreted in terms of different semantics of why & other wh-questions. Z. Dubiel.

We present a detailed process theory of the moment‐by‐moment working‐memory retrievals and associated control structure that subserve sentence comprehension. The theory is derived from the application of independently motivated principles of memory and cognitive skill to the specialized task of sentence parsing. The resulting theory construes sentence processing as a series of skilled associative memory retrievals modulated by similarity‐based interference and fluctuating activation. The cognitive principles are formalized in computational form in the Adaptive Control of Thought–Rational (ACT–R) architecture, and our (...) process model is realized in ACT–R. We present the results of 6 sets of simulations: 5 simulation sets provide quantitative accounts of the effects of length and structural interference on both unambiguous and garden‐path structures. A final simulation set provides a graded taxonomy of double center embeddings ranging from relatively easy to extremely difficult. The explanation of center‐embedding difficulty is a novel one that derives from the model' complete reliance on discriminating retrieval cues in the absence of an explicit representation of serial order information. All fits were obtained with only 1 free scaling parameter fixed across the simulations; all other parameters were ACT–R defaults. The modeling results support the hypothesis that fluctuating activation and similarity‐based interference are the key factors shaping working memory in sentence processing. We contrast the theory and empirical predictions with several related accounts of sentence‐processing complexity. (shrink)

The investigations reported here are the result of three lucky events. The first occurred in 1986. I had recently done the work reported in Pesetsky (1987), and received in the mail a copy of Kiss (1986). Since I had argued at length that D-linked wh-phrases do not display Superiority effects. I was astonished by a paradigm reported by Kiss, which appears here as example (98). These facts remained stubbornly in my mind for the next decade as an unsolved puzzle. Kiss (...) did not publish this paper in the form that I received — and, in fact, did not even recall discovering the crucial facts when she heard this work presented as a talk in 1998. But the facts are hers nonetheless. (shrink)

In explicit memory recall and recognition tasks, elaboration and contextual isolation both facilitate memory performance. Here, we investigate these effects in the context of sentence processing: targets for retrieval during online sentence processing of English object relative clause constructions differ in the amount of elaboration associated with the target noun phrase, or the homogeneity of superficial features (text color). Experiment 1 shows that greater elaboration for targets during the encoding phase reduces reading times at retrieval sites, but elaboration of non-targets (...) has considerably weaker effects. Experiment 2 illustrates that processing isolated superficial features of target noun phrases --- here, a green word in a sentence with words colored white --- does not lead to enhanced memory performance, despite triggering longer encoding times. These results are interpreted in the light of the memory models of Nairne 1990, 2001, 2006, which state that encoding remnants contribute to the set of retrieval cues that provide the basis for similarity-based interference effects.

“D-linked” wh-phrases such as 'which car' are known to increase the acceptability of sentences with island violations. One influential account of this attributes the effect to working memory: the D-linked filler is easier to retrieve at the site of the gap and this leads to the amelioration in acceptability. Such an account predicts that this effect should occur in general with non-trivial wh-dependencies, not just in island environments. An experiment is presented here to test this prediction. Wh-questions with both D-linked (...) and bare wh-phrases and with both island and non-island embedded clauses are presented to participants, who rate their acceptability on a 7-point scale. Results show that D-linking significantly increases acceptability in both island and non-island environments, in accord with analyses that attribute the effect to working memory. In addition, the increase in acceptability is uniform in both types of environments, suggesting that the island effect itself may not be attributable to working memory. (shrink)

In this article we provide evidence for a Minimalist account of English-type resumptive pronouns. Our findings provide empirical support for syntactic theories that, like Minimalist accounts, allow for competition among derivations. According to our account, resumptive pronouns are spell-outs of traces. For reasons of economy, the resumptive pronoun surfaces only when the derivation with the trace is precluded by syntactic principles. This account predicts that resumptive pronouns should only improve violations of constraints on representation, and not violations of constraints on (...) movement. We tested this prediction by conducting an acceptability judgment task with 36 native speakers of English. The results bore out our prediction; subjects preferred the resumptive pronoun over the trace in cases where the trace itself was illicit, but not in cases where only the movement operation was illicit.
