title: Development and decay of extra-linguistic communication.
abstract: Cognitive Pragmatics theory is concerned with analyzing the cognitive processes underlying communication. In previous works we have explained the emergence of communication in context, as revealed by very young children, and the communicative deficits shown by closed head injury patients. The aim of the present work is an extension of Cognitive Pragmatics to the emergence and the decay of extra-linguistic communication. In particular, we investigate the performance of 2- to 7-year-old children and that of Alzheimer's patients in standard and nonstandard (irony and deceit) pragmatic tasks. The predictions derived by Cognitive Pragmatics are confirmed. Comprehension of pragmatic phenomena which are more complex according to the theory emerges later in the development (Experiment 1), and their decay is most severe in Alzheimer's patients (Experiment 2). We conclude that the framework provided by Cognitive Pragmatics can accommodate both the development and the decay of extra-linguistic communication.
