Spoken communication is only one of many types of human interaction with the environment. The aim of this thesis is to propose a theory of spoken communication based on basic principles of cognition, which govern all our behaviour. To this end, two established theoretical positions are integrated: 1) the skilled intentionality framework (an enactive view of cognition) and 2) a discriminative approach to human communication. According to the resulting theory, communication is a skilful shaping of an interlocutor's envi- ronment which serves to fulfil the agent's positively biased expectations about her own situation. Language is presented as an assemblage of sociomaterial regularities that make this skilful behaviour possible. The suggested perspec- tive is radically action-oriented, in contrast with traditional representational, content-based approaches. The proposed view is then applied to two specific phenomena widely studied within speech sciences (namely categoricality of speech and turn taking) and is confronted with selected empirical findings. Possibilities of empirical testing of the suggested theory are discussed.

In the last decades of the eighteenth century, urban lives were touched by a series of innovations in the technology and aesthetics of illumination. Unfamiliar combinations of new fuel sources and auxiliary equipment (for example, curtains, blinds, glass, mirrors and lampshades) meant that cities looked and felt different during both the day and the night. The spheres of elite, popular, public and private culture explored, exploited and were fascinated by the cultural value of light. Through four case studies in the aesthetics of urban illumination, my thesis demonstrates how the acquisition of skills for the manipulation of transparent and reflective surfaces were crucial when negotiating a balance between self-expression and standards of taste, morality, gender and class. Rather than relying upon canonical examples of the period’s fascination with light, such as the high Romantic idealization of nature’s sunrises and sunsets, my thesis investigates more everyday encounters with light in the built environment: the fashionably genteel pastime of transparent painting; the gendering of light to design both domestic interiors and female identity; the appropriation of patrician top-lighting for public buildings of education and exhibition; and the popularity of illuminated spectacles in commercial pleasure gardens. I argue that these new possibilities of lighting temporarily enabled new possibilities of subjectivity. My historical phenomenology suggests that the formation of perception between 1780 and 1840 was actively directed towards changes in the world through a finely-attuned consciousness of light.

How we approach a poem changes it. Recently, it has been suggested that one readerly approach - a bodily orientation characterised by distance, suspicion, and resistance - risks becoming reflexive, pre-conscious, and predominant. This use-oriented reading allows us to destabilise, denaturalise, dissect, defend, and define poetic texts through its manifestation in contemporary literary critique, yet it is coming to be regarded as the sole manner and mood of intelligent, intellectual engagement. In this thesis, I demonstrate the need to pluralise this attentive orientation, particularly when it comes to contemporary lyric poetry. I suggest how an overlooked mode of response might foster a more receptive mode of approach: the 'co-creative' response. Lyric poems mean to move us, and they come to mean by moving us. Recent 'simulation theories of language comprehension', from the field of cognitive neuroscience, provide empirical evidence that language processing is not a product of a-modal symbol manipulation but rather involves 'simulations' by certain classes of neurons in areas used for real-world action and perception. As habituation and abstraction increase, however, these embodied simulations 'streamline', becoming narrow schematic 'shadows' of once broad, qualitatively rich simulations. Poems, I suggest, seek to reverse this process by situationally novel variations of language, coming to mean in the broadly embodied sense in which real-world experiences 'mean'. Readers are asked to 'enact' the poem, to 'co-create' its meaning. Where critique traditionally requires that readers resist enactive participation in the aim of objective analysis, the co-creative response - a response 'in kind' by imitation, versioning, or hommage - asks readers to receive and carry forward the enactive unfolding of a poem with a composition of their own. I assert that, by thus responding with - rather than to - poems, we might foster an attentive stance of active receptivity, thereby coming to understand poems as the enactive phenomena they are.
