The storytelling in sequence test: assessing theory of mind through discourse production.

Résumé

Introduction: We present first normative data of a new interactive task, the storytelling in sequence test, used to evaluate theory of mind's abilities via discourse production. Derived from a princeps study [1], this test assesses the ability to update mental representations of another person's knowledge with a referential communication paradigm. This paradigm allows examining the (co)construction of a mutual knowledge through the differentiated use of reference linguistics markers (anaphoric pronouns, definite and indefinite markers). Method: 45 French-Speaking Swiss speakers (two age groups: 19-39 and 40-49) participated to the storytelling test. They were asked to tell 9 story sequences to another person whose task was to order these pictures correctly. The 9 sequences, of three increasing difficulty levels, were built to elicit 3 referential speech steps: introduction, maintain and shift of character. For each step of each sequence, we used the verbal productions of our groups to calculate a conventionality index (CI) of each referential marker [2]. Results: In both age groups, the type of conventional referential markers differed according to referential speech step: on average across both groups, CI was 0.75 for indefinite markers in introduction step; 0.87 for anaphoric pronouns in maintain step, and 0.57 for definite markers in shift step. Conclusion: Healthy speakers conventionally adjust their referential marker use to the presumed knowledge of their interlocutor. Interestingly these CI may be used as normative data enabling one to calculate personal scores of conventionality (SPECs) for patients with communicative deficits (i.e. schizophrenia, TCC…). The storytelling in sequence test is the first task designed to propose norms to assess the (co)construction of mutual knowledge through analysis of reference linguistic markers.
