Liminality as a lens on social meaning: A cross-variable analysis of gender in New Zealand English

<p>The variationist sociolinguistic enterprise has been successful in developing models of structural (i.e., language-internal) drivers of variation and change, but one of the barriers preventing the development of a parallel model accounting for social drivers is the difficulty in operationalising salience. Using a corpus of sociolinguistic interviews collected in Auckland, New Zealand between 2013 and 2015, this project examines the relationship between language variation and gendered identity, and proposes an analytical approach of liminality – of examining the linguistic practices of people who have crossed a culturally-reified category boundary – as a possible solution to the problem of identifying socially salient variables. The participants in this study are straight, queer, and transsexual native speakers of New Zealand English (NZE), representing two age groups that straddle the period of social change in the 1980s that saw a destabilisation of traditional gender roles in New Zealand. Variation in three linguistic systems is examined: adjectival modifiers (intensifiers and moderators), sibilants (/s/, /z/ and /ʃ/), and the vowels of NZE. The project uses established variationist and sociophonetic methodologies, as well as introducing a new metric for making comparisons across the vowel space as a whole. The findings show that speakers are able to encode their gendered identity across multiple variables, and that subtle linguistic signals can be used to affiliate with (or distance from) particular groups. The two most ‘distant’ groups are older straight men and younger [straight, queer, and transsexual] women, which this thesis argues is a reflection of the general societal criticism directed at young women by hegemonic masculinities. There is also evidence that the mainstreaming of queer identities in the wake of the 1986 decriminalisation of homosexuality has decreased the linguistic distance between straight and queer urban New Zealanders, demonstrating the relative rapidity with which social changes can be incorporated into the linguistic system. This study highlights the utility of studying variation across linguistic systems rather than in variables in isolation, and proposes a typology of variation based on the boundedness and dimensionality of the linguistic systems under investigation. The framework of liminality is found to be productive with respect to the role of gender in language variation, although future research will have to test whether this framework can be generalised to other dimensions of social identity that are perceived as categorical (e.g., ethnicity and heritage culture in immigrant communities).</p>

Response Category Functioning on the Health Care Engagement Measure Using the Nominal Response Model

As part of a scale development project, we fit a nominal response item response theory model to responses to the Health Care Engagement Measure (HEM). When using the original 5-point response format, categories were not ordered as intended for six of the 23 items. For the remaining, the category boundary discrimination between Categories 0 ( not at all true) and 1 ( a little bit true) was only weakly discriminating, suggesting uninformative categories. When the lowest two categories were collapsed, psychometric properties improved greatly. Category boundary discriminations within items, however, varied significantly. Specifically, higher response category distinctions, such as responding 3 ( very true) versus 2 ( mostly true) were considerably more discriminating than lower response category distinctions. Implications for HEM scoring and for improving measurement precision at lower levels of the construct are presented as is the unique role of the nominal response model in category analysis.

Neural Hierarchy of Color Categorization: From Prototype Encoding to Boundary Encoding

A long-standing debate exists on how our brain assigns the fine-grained perceptual representation of color into discrete color categories. Recent functional magnetic resonance imaging (fMRI) studies have identified several regions as the candidate loci of color categorization, including the visual cortex, language-related areas, and non-language-related frontal regions, but the evidence is mixed. Distinct from most studies that emphasized the representational differences between color categories, the current study focused on the variability among members within a category (e.g., category prototypes and boundaries) to reveal category encoding in the brain. We compared and modeled brain activities evoked by color stimuli with varying distances from the category boundary in an active categorization task. The frontal areas, including the inferior and middle frontal gyri, medial superior frontal cortices, and insular cortices, showed larger responses for colors near the category boundary than those far from the boundary. In addition, the visual cortex encodes both within-category variability and cross-category differences. The left V1 in the calcarine showed greater responses to colors at the category center than to those far from the boundary, and the bilateral V4 showed enhanced responses for colors at the category center as well as colors around the boundary. The additional representational similarity analyses (RSA) revealed that the bilateral insulae and V4a carried information about cross-category differences, as cross-category colors exhibited larger dissimilarities in brain patterns than within-category colors. Our study suggested a hierarchically organized network in the human brain during active color categorization, with frontal (both lateral and medial) areas supporting domain-general decisional processes and the visual cortex encoding category structure and differences, likely due to top-down modulation.

Early linguistic experience shapes bilingual adults’ hearing for phonemes in both languages

How do bilinguals represent category structure for phonemes in early acquired languages? /b/ and /p/ voice onset times (VOTs) are earlier and closer together in English than in Mandarin. Hence the category boundary and the steepness of the transition can show ‘tuning’ to language-specific acoustic structure (i.e., earlier boundary and steeper slope for English). As preregistered, we mapped identification functions of early English-Mandarin bilingual adults (N=66) on a /b/ - /p/ VOT continuum in each language. Individual bilingual-balance was derived using principal component analysis and entered into GLMMs of categorical boundary and slope. As predicted, VOTs were earlier for English than Mandarin. Early bilingual-balance predicted the slope of the transition between categories: Those who heard more English from an earlier age showed steeper slopes than those who heard more Mandarin. Findings are consistent with discrete representations for each language, and transfer of category structure from the earlier acquired language.

Silence and its mechanisms as the discursive production of the ‘normal’ in the early childhood classroom

In this paper, we aim to better understand and trouble the discursive (re)production of what is taken as the ‘normal’ in ‘inclusive’ early childhood classrooms. We do so by exploring the practices of the ‘including’ group, the so-called ‘normal, in relation to or in the presence of those who are variously labeled as ‘non-normal’. We highlight those mechanisms that are associated with silence and taboo, and through which the including group produces and maintains itself. We present data produced during a six-month ethnographic study in three early childhood classrooms in Australia. Using the notion of category boundary work in the analysis, we illuminate the practices of silence: ‘ignoring’, ‘moving away’, ‘turning away’ and ‘keeping silent’ through which children undertake the category work of the ‘normal’. The effect of this category work, we argue, is that disability or the diagnosed subject becomes ‘the elephant in the room’, strongly present but avowedly ignored. We draw out some considerations for practice in the concluding part of the paper.

Pattern Separation Contributes to Categorical Face Perception

Traditionally considered a memory structure, the hippocampus has been shown to contribute to non-memory functions, from perception to language. Recent evidence suggests that the ability to differentiate highly confusable faces could involve pattern separation, a mnemonic process mediated by the hippocampal dentate gyrus (DG). Hippocampal involvement, however, may depend on existing face memories. To investigate these possibilities, we tested BL, a rare individual with bilateral lesions selective to the DG, and healthy controls. Both were administered morphed images of famous and nonfamous faces in a categorical perception (CP) identification and discrimination experiment. All participants exhibited nonlinear identification of famous faces with a midpoint category boundary. Controls identified newly learned nonfamous faces with lesser fidelity, while BL showed a notable shift in category boundary. When discriminating face pairs, controls showed typical CP effects of better between-category than within-category discrimination — but only for famous faces. BL showed extreme within-category “compression,” reflecting his tendency to pattern complete following suboptimal pattern separation. We provide the first evidence that pattern separation contributes to CP of faces.
