Investigating the Difficulty of Two Spoken Narrative Tasks

3. Pilot Studies 3.1 Introduction Following on from the research questions (RQs) presented in the pre- vious chapter, Chapter 3 introduces a series of pilot studies to help refine the research methodology. First of all, there need to be pilot studies in order to select appropriate narrative tasks that are seemingly equivalent in terms of the task complexity factors identified in Section 2.5.2: code complexity, topic familiarity and prior knowledge, the number of elements drawn in the picture, as well as the demands for intentional and causal reasoning. After such careful selection, investi- gating task difficulty with contextual factors, as suggested by Bach- man (2002), can be realised via RQ1. Additionally, the feasibility of identifying the characteristics of linguistic performance should be examined. Both of these are explored in Pilot Studies 1 and 2, using a publicly available spoken corpus of the performances of Japanese learners of English called the NICT JLE Corpus (The National Insti- tute of Information and Communications Technology Japanese Learner English Corpus). The transcripts data in this corpus comprise over 1,200 interviews from a test of speaking English in Japan, the Standard Speaking Test (SST), which involves spoken narrative tasks. Although the SST uses its own rating scales to rate candidates’ per- formance and not the CEFR assessment grid, the corpus still provides invaluable information about the candidates’ English speaking profi- ciency levels, some background information, and which spoken narra- tive task (among several choices) were selected and given12. 12 As the author was trained...
