No bones about it (or are there?)
Title
No bones about it (or are there?): evaluating markedness constraints on structural representations of the phonology skeleton.
Creator

Abstract/Description
Linguistic research suggests that speakers represent syllable structure by a CV-frame. CVC syllables are more frequent than VCC ones. Further, the presence of VCC syllables in a language asymmetrically implies the presence of CVC syllables. These typological facts may reflect grammatical constraints. Alternatively, people's preferences may be due solely to their sensitivity to the statistical properties of sound combinations in their language. I demonstrate that participants in an auditory...
Show moreLinguistic research suggests that speakers represent syllable structure by a CV-frame. CVC syllables are more frequent than VCC ones. Further, the presence of VCC syllables in a language asymmetrically implies the presence of CVC syllables. These typological facts may reflect grammatical constraints. Alternatively, people's preferences may be due solely to their sensitivity to the statistical properties of sound combinations in their language. I demonstrate that participants in an auditory lexical decision task reject VCC nonwords faster than CVC nonwords, suggesting that the marked VCC syllables are dispreferred relative to CVC syllables. In a second experiment, I show that people are also sensitive to the distribution of these frames in the experiment. Findings indicate that syllable structure is represented at the phonological level, that individuals have preferences for certain syllables, and that these preferences can not be accounted for by the statistical properties of the stimuli.

Time, space, and Shakespeare: Temporal and spatial disturbances at the point of cultural contact
Title
Time, space, and Shakespeare: Temporal and spatial disturbances at the point of cultural contact.
Creator
Murray, Jessica L., Florida Atlantic University, Low, Jennifer A.
Abstract/Description
Cultural geographic theory uses dramatic language (place ballets , time-space routines, temporal rhythms , etc.) to describe how humans sense and dwell in places. Because the theory contemplates human behavior enacted upon a stage, it is applicable to theater studies. This thesis asserts that Hamlet's, Othello's, and Antony's treacherous lifeworlds undermine their spatiotemporal senses and initiate quests similar to those described by Anne Buttimer as searches "for order, predictability, and...
Show moreCultural geographic theory uses dramatic language (place ballets , time-space routines, temporal rhythms , etc.) to describe how humans sense and dwell in places. Because the theory contemplates human behavior enacted upon a stage, it is applicable to theater studies. This thesis asserts that Hamlet's, Othello's, and Antony's treacherous lifeworlds undermine their spatiotemporal senses and initiate quests similar to those described by Anne Buttimer as searches "for order, predictability, and routine, as well as [...] for adventure and change" ("Grasping" 285). Hamlet's revenge plot is a pursuit of order and reclamation of his identity at Elsinore. Desdemona's murder is Othello's attempt to salvage his character, which he believed sullied by infidelity. Alexandria offers Antony a life opposite Rome's and sets him on a course of indecisiveness. These plays demonstrate that, at the point of cultural contact, routines are interrupted and identities destabilize. Tragically, the characters lose themselves in the turmoil.

Theoretical and experimental studies of multisensory integration as a coupled dynamical system

Theoretical and experimental studies of multisensory integration as a coupled dynamical system.

Abstract/Description
Perception and behavior are mediated by a widely distributed network of brain areas. Our main concern is, how do the components of the network interact in order to give us a variety of complex coordinated behavior? We first define the nodes of the network, termed functional units, as a strongly coupled ensemble of non-identical neurons and demonstrate that the dynamics of such an ensemble may be approximated by a low dimensional set of equations. The dynamics is studied in two different...
Show morePerception and behavior are mediated by a widely distributed network of brain areas. Our main concern is, how do the components of the network interact in order to give us a variety of complex coordinated behavior? We first define the nodes of the network, termed functional units, as a strongly coupled ensemble of non-identical neurons and demonstrate that the dynamics of such an ensemble may be approximated by a low dimensional set of equations. The dynamics is studied in two different contexts, sensorimotor coordination and multisensory integration. First, we treat movement coupled to the environment as a driven functional unit. Our central hypothesis is that this coupling must be minimally parametric. We demonstrate the experimental validity of this hypothesis and propose a theoretical model that explains the results of our experiment. A second example of the dynamics of functional units is evident in the domain of multisensory integration. We employ a novel rhythmic multisensory paradigm designed to capture the temporal features of multisensory integration parametrically. The relevant parameters of our experiment are the inter-onset interval between pairs of rhythmically presented stimuli and the frequency of presentation. We partition the two dimensional parameter space using subjects perception of the stimulus sequence. The general features of the partitioning are modality independent suggesting that these features depend on the coupling between the unisensory subsystems. We develop a model with coupled functional units and suggest a candidate coupling scheme. In subsequent chapters we probe the neural correlates of multisensory integration using fMRI and EEG. The results of our fMRI experiment demonstrate that multisensory integration is mediated by a network consisting of primary sensory areas, inferior parietal lobule, prefrontal areas and the posterior midbrain. Different percepts lead to the recruitment of different areas and their disengagement for other percepts. In analyzing the EEG data, we first develop a mathematical framework that allows us to differentiate between sources activated for both unisensory and multisensory stimulation from those sources activated only for multisensory stimulation. Using this methodology we show that the influences of multisensory processing may be seen at an early (40--60 ms) stage of sensory processing.
