The morphology-phonology interface: Isolating to polysynthetic languages

Given the substantial variation in the nature of the grammatical word (GW) across languages, this paper addresses the question of whether the Phonological Word (PW) exhibits the same degree of variation or rather abstracts away from it due to the typically flatter nature of the phonological hierarchy. Various types of languages are examined, focusing on isolating and polysynthetic languages—opposite ends of a word structure continuum. It is demonstrated that, indeed, the PW exhibits substantially less variation across languages than might be expected on the basis of the differences in GW structure. Furthermore, it is shown that an additional constituent (i.e., the Clitic Group, renamed Composite Group) is required between the PW and the Phonological Phrase to fully account for the interface between morpho-syntactic and phonological structures

Impact of Prenatal Immune System Disturbances on Brain Development

As research into various aging-associated neurodegenerative disorders reveals their immense pathophysiological complexity, the focus is currently shifting from studying changes in an advanced disease state to investigations involving pre-symptomatic periods, possible aberrations in early life, and even abnormalities in brain development. Recent studies on the etiology of schizophrenia and autism spectrum disorders revealed a profound impact of neurodevelopmental disturbances on disease predisposition, onset and progression. Here, we discuss how a prenatal immune challenge can affect the developing brain—with a selective focus on the impact on microglia, the brain's immune cells—and the implications for brain aging and its associated risk of developing Alzheimer's diseas

The Effect of Focus on Creaky Phonation in Mandarin Chinese Tones

Previous studies of the prosodic realization of focus in Mandarin Chinese show an expansion of the pitch range of lexical tones. It is less clear, however, whether focus affects the Creaky Phonation (CP) that often co-occurs with the Dipping third tone (T3), and to some extent, also with the Falling fourth tone (T4). This study investigates the effect of focus on the acoustic properties of the four Mandarin tones, and while it confirms the expansion of the pitch range under focus, it does not find that focus affects CP in T3; it only finds an effect of focus on CP in T4. Both the F0 and CP patterns are also considered in relation to the Functional Load Hypothesis, specifically, the relationship between the contrastive properties of a language and the manifestation of prominence

Acoustic properties of word and phrasal prominence in Uzbek

Based on a large-scale corpus of experimental data produced by 8 native speakers of Tashkent Uzbek, we assess the presence of canonical word-final stress in real words spoken in three dialogue types: without focus, with contrastive focus, and with new information focus on the target. The first context provides baseline information regarding the manifestation of stress, in the absence of additional focus properties. By comparing the latter two contexts with the former, we are also able to assess the acoustic manifestation of the two types of focus. The most noteworthy properties of the final syllable are its relatively long duration and sharp falling contour, potentially serving as the cues to lexical stress, and enhanced by both types of focus. Due to the word-final position of stress, however, the patterns we observe could also be consistent with boundary properties, a possibility we consider as well. In addition, we briefly compare the prosodic patterns we observe in Uzbek with similarly collected data in Turkish. We find that the prominence patterns in Uzbek, while not particularly strong, are nevertheless stronger than those in Turkish, and also exhibit crucial differences. Implications for Turkic prosody more generally are also suggested

Palatalization in Romanian — Acoustic properties and perception

This paper presents the results of an acoustic study of fricatives from four places of articulation produced by 31 native speakers of Romanian, as well as those of a perceptual study using the stimuli from the acoustic experiment, allowing for a direct comparison between acoustic properties and perception. It was found that there are greater acoustic differences between plain and palatalized labials and dorsals as compared to coronals. The acoustic results were paralleled by the perceptual findings. This pattern departs from cross-linguistic generalizations made with respect to the properties of secondary palatalization. A likely source of the differences is the fact that previous studies of secondary palatalization typically involved stops which tend to exhibit various enhancement phenomena at the coronal place of articulation. Since the enhancement generally involves additional frication, this is not a useful strategy for fricatives at the coronal, or any other place of articulation. These findings form the basis of a discussion highlighting the differences between enhanced and non-enhanced secondary palatalization

Perceptual Confusion of Mandarin Tone 3 and Tone 4

In connected speech, the acoustic properties of Mandarin tones undergo modifications not observed in isolation. The current study investigated the perceptual distinction between Mandarin tones in connected speech, focusing on Tone 3 and Tone 4, which have been reported to share a similar initial falling contour. The current study also tested whether syllables produced with focus and / or in certain syllable positions affect the tonal perception. In a forced choice perception task, participants heard syllables extracted from three syllable words previously recorded in short dialogues, and were instructed to select one of four characters representing corresponding monosyllabic words differing only in tone. The accuracy results showed that Tone 4 was much more successfully identified than Tone 3. Nonetheless, after using a d-prime analysis to control for an observed T4 response bias, we found the same level of perceptibility of T3 and T4. Furthermore, the two tones were better perceived when a tone was produced in a focus context or at the edge of a word, confirming the effect of prosodic structure on tonal perception
