Mental State Inferences Abilities Contribution to Verbal Irony Comprehension in Older Adults with Mild Cognitive Impairment

Abstract EN

Objective.

The present study examined mentalizing capacities as well as the relative implication of mentalizing in the comprehension of ironic and sincere assertions among 30 older adults with mild cognitive impairment (MCI) and 30 healthy control (HC) subjects.

Method.

Subjects were administered a task evaluating mentalizing by means of short stories.

A verbal irony comprehension task, in which participants had to identify ironic or sincere statements within short stories, was also administered; the design of the task allowed uniform implication of mentalizing across the conditions.

Results.

Findings indicated that participants with MCI have second-order mentalizing difficulties compared to HC subjects.

Moreover, MCI participants were impaired compared to the HC group in identifying ironic or sincere stories, both requiring mental inference capacities.

Conclusion.

This study suggests that, in individuals with MCI, difficulties in the comprehension of ironic and sincere assertions are closely related to second-order mentalizing deficits.

These findings support previous data suggesting a strong relationship between irony comprehension and mentalizing.
