Identifying the \u27aboutness\u27 of highly structured expository documents

The increases in commercial documentation over the past 50 years and the permeation of computers into all areas of business has led to a major increase in the individual\u27s reading load. This thesis proposes a method of writing procedural documentation to enable rapid appreciation of the \u27aboutness\u27 of such material, thus making the reading task more efficient. The method is derived from a document structure which is used as a basis for the development of rules to construct a hierarchy of in-text headings which encapsulates the \u27aboutness\u27 of the text. Reading efficiency is achieved through needing to only interpret the headings to understand what the document is about. The method was tested by having control and experimental groups complete the same series of questions, answers to which were derived from a set of documents. The set used by participants in the experimental group contained headings structured according to the proposed method; the set used by participants in the control group contained headings which were not structured according to the proposed method. All variables other than headings were negated or neutralised. Answer accuracy and completion times of the groups were compared. On average the experimental group, who used documents containing headings structured according to the proposed method, had 7.5% better accuracy and completed the questions in 13.5% less time overall. These improvements are assumed to be due to the differences in heading effects

A framework for the design of usable electronic text

This thesis examines the human issues underlying the design and usability of electronic text systems. In so doing it develops a framework for the conceptualisation of these issues that aims to guide designers of electronic texts in their attempts to produce usable systems. The thesis commences with a review of the traditional human factors literature on electronic text according to three basic themes: its concern with perceptual, manipulatory and structural issues. From this examination it is concluded that shortcomings in translating this work into design result from the adoption of overly narrow uni-disciplinary views of reading taken from cognitive psychology and information science which are inappropriate to serve the needs of electronic text designers. In an attempt to provide a more relevant description of the reading process a series of studies examining readers and their views as well as uses of texts is reported. In the first, a repertory grid based investigation revealed that all texts can be described in reader-relvant terms according to three criteria: why a text is read, what a text contains and how it is read. These criteria then form the basis of two investigations of reader-text interaction using academic journals and user manuals. The results of these studies highlighted the need to consider readers' models of a document's structure in discussing text usability. Subsequent experimental work on readers' models of academic articles demonstrated not only that such models are important aspects of reader-text interaction but that data of this form could usefully be employed in the design of an electronic text system. The proposed framework provides a broad, qualitative model of the important issues for designers to consider when developing a product It consists of four interactive elements that focus attention on aspects of reading that have been identified as central to usability. Simple tests of the utility and validity of the framework are reported and it is shown that the framework both supports reasoned analysis and subsequent prediction of reader behaviour as well as providing a parsimonious account of their verbal utterances while reading. The thesis concludes with an analysis of the likely uses of such a framework and the potential for electronic text systems in an increasingly information-hungry world

Anaphoric resolution of zero pronouns in Chinese in translation and reading comprehension

The primary aim of the thesis is to investigate some of the processes of reading Chinese text by means of comparing and analysing approximately 100 parallel translations of four texts from Chinese to English. The translations are answers to A Level examination questions. The focus of the investigation is interpretation of the zero pronoun, a common phenomenon in Chinese, which often requires explicitation when translated into English. The secondary aim is to show how translation gives evidence of comprehension, as shown by the variation in interpretation of zero pronouns. The thesis reviews relevant psycholinguistic research into reading, particularly reading of Chinese text. This is followed by reviews of relevant research into translation as a reading activity, and a discussion of its role in language teaching and testing.The core of the thesis is the discussion of the zero pronoun in Chinese, including discussion of anaphoric choice - the writer's decision on when to use zero in preference to an explicit anaphoric form - and of anaphoric resolution - how a reader decides what a zero pronoun refers to. Anaphoric resolution may be problematic for less experienced readers of Chinese owing to its lack of rich morphological inflection which, in other languages, provides the reader with information. Some of the key ideas on anaphoric choice and resolution are then applied to the analysis of the data in the parallel translations. It would appear that factors in Chinese texts which have an effect on comprehending zero pronouns are antecedent distance, topic persistence, abstraction, multiplicity of arguments and the meaning of the verb. Characteristics of the reader which may affect comprehension of the zero pronoun include personal schemata which may lead to elaborative inferences. On the basis of the data I suggest that mark schemes could be devised on a scalar system encompassing optimal solution, proximal solution and nonsolution, which might help to solve the problem of variability in marking translation.A by-product of the thesis, and an avenue for further research, is the apparent close relationship between idea units, clause length, punctuation breaks and antecedent distance in Chinese texts and saccade length and working memory capacity in the reader of Chinese

Augmentative communication device design, implementation and evaluation

The ultimate aim of this thesis was to design and implement an advanced software based Augmentative Communication Device (ACD) , or Voice Output Communication Aid NOCA), for non-vocal Learning Disabled individuals by applying current psychological models, theories, and experimental techniques. By taking account of potential user's cognitive and linguistic abilities a symbol based device (Easy Speaker) was produced which outputs naturalistic digitised human speech and sound and makes use of a photorealistic symbol set. In order to increase the size of the available symbol set a hypermedia style dynamic screen approach was employed. The relevance of the hypermedia metaphor in relation to models of knowledge representation and language processing was explored.Laboratory based studies suggested that potential user's could learn to productively operate the software, became faster and more efficient over time when performing set conversational tasks. Studies with unimpaired individuals supported the notion that digitised speech was less cognitively demanding to decode, or listen to.With highly portable, touch based, PC compatible systems beginning to appear it is hoped that the otherwise silent will be able to use the software as their primary means of communication with the speaking world. Extensive field trials over a six month period with a prototype device and in collaboration with user's caregivers strongly suggested this might be the case.Off-device improvements were also noted suggesting that Easy Speaker, or similar software has the potential to be used as a communication training tool. Such training would be likely 10 improve overall communicative effectiveness.To conclude, a model for successful ACD development was proposed

Genre-based literacy pedagogy: the nature and value of genre knowledge in teaching and learning writing on a university first year media studies course

A thesis submitted to the Faculty of Humanities, Uniiversity of Luton, in partial fulfilment of the requirements for the degree of Doctor of PhilosophyIn the teaching and learning of literacy, descriptions of text have a problematic status as a result of the growing understanding of literacy as both a cognitive process and a social practice. In the teaching of academic subjects at university, student text is not usually an object of study. The research in this thesis draws on a language based theory oflearning to place textual description at the centre of the teaching and learning of both literacy and academic subjects at university. Participant observation and practice-based research methods were used to implement a form of text-oriented literacy teaching and to explore its compatibility with processes and practices orientations to literacy. Over an eighteen month period, systemic functional grammar was used to investigate and describe the texts of a film studies classroom and the descriptions were used in genre based literacy pedagogy. The effects of the pedagogy are measured in terms of students' performance in an end of course assignment, students' accounts of their writing processes, and student and subject-tutor perception of the text description and the pedagogy. In the thesis, a linguistic description of a key curriculum genre -a Taxonomic Film Analysis -is presented. An account is given of the pedagogy by means of which this essay genre was represented in the film studies classroom as a realisation of choices from linguistic, conceptual and activity systems. Systemic functional grammar-based text description is seen to have provided a means whereby a literacy tutor could collaborate with a subject tutor to provide a subject-specific form of literacy teaching which was evaluated as relevant by students and tutors. The account and the evaluation help to clarify the role that description of text can play in relation to processes and practices ofliteracy use in the teaching and learning of literacy in a film studies classroom and have implications for the teaching and learning of literacy at university more generally
