Listening comprehension is an active skill, which sets in motion a series of linguistic and non-linguistic mechanisms. It involves developing the ability to listen in order to understand what others are saying. In addition, to evaluate this skill, the tests used would consist of the administration of oral commands, the transmission of stories after which comprehension would be evaluated through questions. People who begin with the development of dementia have more difficulty in correctly understanding irony and in general present worse performance in all tests assessing oral comprehension.
