Crosslinguistic Variation

We propose a theory of head displacement that replaces traditional Head Movement and Lowering with a single syntactic operation of Generalized Head Movement. We argue that upward and downward head displacement have the same syntactic properties: cyclicity, Mirror Principle effects, feeding upward head displacement, and being blocked in the same syntactic configurations. We also study the interaction of head displacement and other syntactic operations, arguing that claimed differences between upward and downward displacement are either spurious or follow directly from our account. Finally, we show that our theory correctly predicts the attested crosslinguistic variation in verb and inflection doubling in predicate clefts.

This chapter examines polysynthetic word formation in Inuit (Eskimo-Aleut), using the presence and variable ordering of a closed class of adverbs within verbal complexes as a diagnostic device to evaluate the adequacy of different accounts of word formation. It is argued that a head movement account of Mirror Principle orders within Inuit words undergenerates with respect to the observed variation in adverb ordering, particularly if a fixed hierarchy of adverbial functional projections is assumed, as in Cinque (1999). Instead, it is shown that an analysis that employs a right-headed structure, XP-sized phasal words, and Ernst’s (2002) semantically based framework of adverb licensing better captures the observed variation.

AbstractBlast exposure can injure brain by multiple mechanisms, and injury attributable to direct effects of the blast wave itself have been difficult to distinguish from that caused by rapid head displacement and other secondary processes. To resolve this issue, we used a rat model of blast exposure in which head movement was either strictly prevented or permitted in the lateral plane. Blast was found to produce axonal injury even with strict prevention of head movement. This axonal injury was restricted to the cerebellum, with the exception of injury in visual tracts secondary to ocular trauma. The cerebellar axonal injury was increased in rats in which blast-induced head movement was permitted, but the pattern of injury was unchanged. These findings support the contentions that blast per se, independent of head movement, is sufficient to induce axonal injury, and that axons in cerebellar white matter are particularly vulnerable to direct blast-induced injury.

Verb Doubling

When a verb or verb phrase is fronted from a clause lacking any other verbs either a copy of the displaced verb occurs or a dummy verb ‘do’ is inserted. Most languages employ the same strategy for both verb and verb phrase fronting. Here, I present two African languages, Asante Twi and Limbum, where displacement of a single verb results in a verb copy while a full verb phrase triggers do-support when fronted. Both V and VP-fronting show the same syntactic properties within each language. A reverse pattern of verb doubling with VP-fronting but do-support with V-fronting is unattested. I propose an analysis of both strategies in terms of different orders of application between post-syntactic head movement and copy deletion. In interaction with the type of V-movement, remnant VP or head-to-spec movement, this derives all three attested patterns to the exclusion of the unattested one.

Mirror Principle

We argue for a unified account of head movement and lowering in which lowering is in essence the covert movement counterpart of head movement. This proposal is supported by the existence of successive cyclic lowering (evidenced by relative prefix formation in Ndebele), in which complex heads built by lowering have the Mirror-Principle-obeying structure expected under a head movement derivation. It also predicts that lowering can feed head movement, giving the appearance of long head movement, which we argue is the case in Mainland Scandinavian V2.

I make two proposals in this article: (a) an economy condition on the operation Copy, which states that Copy should apply to as small an element as possible, and (b) the “two types of head movement” hypothesis, which states that Universal Grammar allows head movement via substitution as well as head movement via adjunction. I argue that with these proposals, we can not only explain two generalizations about what I call headless XPs, but also attribute crosslinguistic variation in the applicability of these generalizations to parameters that are responsible for the availability of multiple specifiers.

Purpose The aim of the study was to explore the potential of performance on a Danish sentence repetition (SR) task—including specific morphological and syntactic properties—to identify difficulties in children with developmental language disorder (DLD) relative to typically developing (TD) children. Furthermore, the potential of the task as a clinical marker for Danish DLD was explored. Method SR performance of children with DLD aged 5;10–14;1 (years;months; n = 27) and TD children aged 5;3–13;4 ( n = 87) was investigated. Results Compared to TD same-age peers, children with DLD were less likely to repeat the sentences accurately but more likely to make ungrammatical errors with respect to verb inflection and use of determiners and personal pronouns. Younger children with DLD also produced more word order errors that their TD peers. Furthermore, older children with DLD performed less accurately than younger TD peers, indicating that the SR task taps into morphosyntactic areas of particular difficulty for Danish children with DLD. The classification accuracy associated with SR performance showed high levels of sensitivity and specificity (> 90%) and likelihood ratios indicating good identification potential for clinical and future research purposes. Conclusion SR performance has a strong potential for identifying children with DLD, also in Danish, and with a carefully designed SR task, performance has potential for revealing morphosyntactic difficulties.

Pure Tones

Twelve blindfolded subjects localized two different pure tones, randomly played by eight sound sources in the horizontal plane. Either subjects could get information supplied by their pinnae (external ear) and their head movements or not. We found that pinnae, as well as head movements, had a marked influence on auditory localization performance with this type of sound. Effects of pinnae and head movements seemed to be additive; the absence of one or the other factor provoked the same loss of localization accuracy and even much the same error pattern. Head movement analysis showed that subjects turn their face towards the emitting sound source, except for sources exactly in the front or exactly in the rear, which are identified by turning the head to both sides. The head movement amplitude increased smoothly as the sound source moved from the anterior to the posterior quadrant.

Minimalist Framework

The current paper examines the syntactic properties of HA stripping: a type of ellipsis. Within the Minimalist framework, the paper adopts the PF-Deletion approach to show that stripping in HA is derived firstly by the movement of the remnant constituent from TP to Focus Position (FP), and, secondly, by the deletion of the TP. These two operations are licensed by the Ellipsis feature (E) located in the focus head F°. Thus, on the one hand, the paper contributes to the existing body of literature supporting the hotly-debated issues on the movement of the stripping remnants, and on the other, enriches the very minimal HA studies on ellipsis. The findings show that HA stripped constituents must move to Spec, FP, before the TP- deletion process. Two pieces of evidence in support of the focus movement to FP spring from Island sensitivity and p-stranding facts in HA.
