The purpose of this study was to reveal the characteristics of analysis units for measuring listening recall protocols. Following Jimura (2007a; 2007b), the present study focused on Idea Unit based on the definition provided by of Sakai (2005) and Tone Unit on provided by Brazil (1994). Eighty-three participants were asked to listen to passages and then write down everything they could remember from them. Each of the recall protocols were scored against the two analysis units. The scores of each analysis unit were analyzed mainly in terms of validity and reliability. The main findings are as follows: (1) the criteria of Idea Unit might be stricter than those of Tone Unit for the assessment of the protocols; (2) there was little difference between Idea Unit and Tone Unit with regard to the relationship with an external criterion measure, interrater reliability and internal consistency; and (3) the identjfIcation of Tone Unit boundaries was less reliable than that of Idea Unit boundaries. Finally, this study offered important research implications illustrating the data obtained by cluster analyses.
