Story tellers have been found to use a variety of evaluative strategies to express their judgments and perspectives while telling a story. However, the classification of strategies varies among studies in the literature, which makes it difficult to compare these studies or apply the strategies to new sets of data. These studies were mainly conducted in English; thus, classifications based on English forms cannot be used in other languages. The present study aims to establish a valid and reliable classification of evaluative strategies. Twenty-nine native Japanese speakers were asked to narrate a picture story, “Frog, Where are You?”, and evaluative clauses and phrases in the narratives were extracted based on the linguistic forms. Evaluative clauses and phrases were then classified based on the functions they serve in their immediate context. More specifically, evaluative clauses were categorized into four types: (a) references to “frames of mind,” (b) references to judgments, (c) references to intentions, purposes, etc., and (d) references to hypotheses, guesses, etc. Evaluative expressions were categorized into five types: (a) references to “frames of mind,” (b) references to judgments, (c) attitudes, (d) information complement, and (e) relationships of events or background information. This classification provides a more reliable and objective framework than measures used in previous studies.
