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.


This project is regarding the Motion controlled wheelchair for disabled. We are going to control motorized wheelchair using a head band having motion sensor and Arduino as controller. Problem: “often disabled who cannot walk find themselves being burden for their families or caretakers just for moving around the house. Disabled who are paralysed below head, who may not have functioning arms cannot control joystick controlled electric wheelchair.” This project is to solve their problem using a motion sensor to control their wheelchair. We are aiming towards building a more affordable, unique, low maintenance and available for all kind of head-controlled wheel chair.

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.

AbstractThe goal of this paper is to address the syntax of certain oblique nominals in Blackfoot (Algonquian) that are introduced by a set of verbal prefixes called linkers. In the literature, an oblique nominal introduced by a verbal affix always shows certain properties of objects, e.g., agreement. This type of affix is analyzed as forming a complex verb with the main verb via head movement, and the oblique nominal is treated as an object of the complex verb. However, this paper demonstrates that oblique nominals introduced by linkers in Blackfoot do not show certain object properties even though the linker looks like it forms a complex verb. Building on the lack of object properties, linker phrases are proposed to be adjuncts. As proposed for adjuncts generally (e.g., Stephanov, Arthur. 2001. Late adjunction and minimalist phrase structure. Syntax 4(2). 94–125), this paper proposes a late merge analysis for linker phrases. Within an Agree-based model (Chomsky, Noam. 2000. Minimalist inquiries: The framework. In Roger Martin, David Michaels & Juan Uriagereka (eds.), Step by step: Essays on minimalist syntax in honor of Howard Lasnik, 89–155. Cambridge, MA: The MIT Press, 2001. Derivation by phase. In Michael Kenstowicz (ed.), Ken Hale: A life in language, 1–52. Cambridge: The MIT Press) where the derivation proceeds by phases (Chomsky 2008), a linker phrase, as an adjunct, lacks the relevant features to participate in the derivation via Agree, and thus it merges late at the end of a given phasal derivation such as vP. When spell out applies, the linker linearizes with a [V-v] complex in the base position, i.e., vP, giving its surface appearance as a verbal affix. Under this view, a linker does not lead to formation of a complex verb as it does not undergo head movement to the verb, unlike applicative affixes, consistent with the absence of object properties.

AbstractIn this paper I discuss three properties of Brazilian Pomeranian, a Germanic language spoken in Espirito Santo, Brazil by descendents who emigrated in the 19th century. These three aspects of the verbal system are: 1. The relation between complex complementizers, a two-infinitive system, and split infinitives, previously discussed in van Gelderen (1993, 1998) and Schallert (2012, 2013), 2. Verb Projection Raising (VPR), as discussed by Riemsdijk 2002, Haegeman 2007, Salzmann 2011, and Brandner & Salzmann 2012, and 3. Verb-Second positioning of verbal clusters, previously discussed in Vos (2005). I discuss novel Pomeranian data from the perspective of the literature on these three topics, which have been thus far studied largely separately from one another. An integrated discussion sheds light on the nature and the proper analysis of these three phenomena. I argue that these phenomena are caused by the “weaknesses” of T. The weakness of T can be resolved “downward” by copying features onto T under selection by a higher head (agree), or can be resolved “upward” under head movement of T.
