Abstract:
A number of researchers have investigated how vocabularies are organised in terms of their depth. This work provides only a partial picture of vocabulary organisation, however, because of the limited aspects of knowledge analysed, and the testing methods employed. There are no standardised tests of vocabulary organisation, and this lack has undoubtedly contributed to the inconclusive results of studies in this area. What vocabulary researchers need is a valid and reliable test of vocabulary organisation. This thesis examines some of the problems which need to be confronted in the development of a tool of this sort. The thesis described a test of Lexical Organisation (LOT) in which test takers are asked to select the strongest collocation in a set of three words. This test was able to distinguish native speakers from non-native speakers, but it was not sensitive enough to distinguish learners at different levels of proficiency. A revised version of LOT, the Two-choice LOT (TCLOT), was more successful in this regard. TCLOT proved to be a reliable test, but its validity as a test of vocabulary organisation was not fully confirmed. The thesis considers the implications of these results for theories of vocabulary size and organisation, and for models of vocabulary which attempt to describe vocabulary knowledge in terms of a small number of orthogonal dimensions.
