NCT04708561

Brief Summary

This study aims to assess speech therapy's effectiveness in understanding other people's thoughts (implied) using written stories. The main objective is to examine whether the therapy improves understanding of the stories worked on in the sessions. We also explore whether the observed progress is maintained one month after the end of treatment and whether it is generalized to neuropsychological tests, video material, and the participants' daily lives. This therapy will be administered to four individuals with brain lesions, for six weeks, at the rate of two weekly sessions of one hour.

Outcome Measures

Primary Outcomes (3)

  • Change from the score on the written task of comprehension of non-literal language 48 hours after the end of the therapy

    The non-literal language comprehension task includes written stories ending with a character's utterance that can be interpreted literally (e.g., "I'm mad at you" to signify her nervousness); ironically (e.g. "it was a fantastic play" to mean the play was bad); as an indirect request (e.g., "Caramels look good" to ask for a caramel); like a lie (e.g. "it was very nice"); like a faux-pas (e.g., criticizing a person without knowing that he or she hears everything). Following these stories, the participant must answer the question: "What does the character mean? ". Each story is scored 0-1-2 depending on the accuracy of the answer. The total score is thus obtained by adding the points received for each of the questions in the task's stories. The stories will be administered twice before the therapy (baselines) and directly (24-48 hours) after the last session of the therapy to analyze the change of performance.

  • Change from the score on the written task of comprehension of non-literal language 1 month after the end of the therapy

Following these stories, the participant must answer the question: "What does the character mean? ". Each story is scored 0-1-2 depending on the accuracy of the answer. The total score is thus obtained by adding the points received for each of the questions in the task's stories. The stories will be administered twice before the therapy (baselines) and one month after the last session of the therapy to analyze the long-term change of performance.

  • Maintenance from the score on the written task of comprehension of non-literal language 1 month after the end of the therapy

    The non-literal language comprehension task includes written stories ending with a character's utterance that can be interpreted literally (e.g., "I'm mad at you" to signify her nervousness); ironically (e.g. "it was a fantastic play" to mean the play was bad); as an indirect request (e.g., "Caramels look good" to ask for a caramel); like a lie (e.g. "it was very nice"); like a faux-pas (e.g., criticizing a person without knowing that he or she hears everything).

The total score is thus obtained by adding the points received for each of the questions in the task's stories. The stories will be administered 24-48 hours and one month after the last session of the therapy to analyze the maintenance of performance.

Behavioral: Speech and language therapy

Interventions

The intervention focuses on understanding the thoughts of the characters. Twenty written stories will be used, which end with statements that can be interpreted literally, ironically, as a lie, a request or a faux-pas (maladroitness). At the end of each story, the participant should explain what the characters want to mean by their statement. To help the participant in his understanding of the character's intention, he will be asked: 1\) To mention as many intentions as possible that can be associated with the target statement presented out of context (eg: "it's hot here" that can be interpreted literally, ironically, as a lie or a request) and to imagine contexts in connection with interpretation; 2. Analyze the relevant elements of the context (environment, the relationship between the characters, knowledge of the characters); 3. To judge the probability of the possible interpretations (pt 1) by justifying using the elements of the context analyzed previously (pt 2).
