Channels of Communication & Brain Functioning: Pilot fMRI Study

Study Overview
=================
Brief Summary
-----------------
Communication is a social process involving individuals exchanging messages. It is usual to observe different reactions according to the manner of communication, the manner in which such information is exchanged. In this work, it will be examined how different communication modalities cause different reactions in a person. We make the assumption that each communication modality is based on a different brain network.

Detailed Description
-----------------
This work will use the Process Communication Model (PCM) that is a tool based on human behavior, created by Taibi Kahler. It helps to understand how people interact and communicate. In order to communicate well with a person, it is convenient to use an adapted channel of communication. PCM focuses on the mastery of fundamental communication skills that are required to adapt and connect with all types of people. The sets of adaptive communications skills are learning, assessing, adapting, predicting and resolution. PCM defines six basic personality types, and four different channels of communication. Each one has one or several favourite channels of communication. On the whole, there are the following four channels of communication: Prescriptive, Informative-Interrogative, fostering, Emotional-Ludic. In the prescriptive channel, the interlocutor should be firm and determined, without being aggressive. The informative/interrogative channel requires a neutral tone of voice, showing no particular emotion. The interlocutor should emphasize using questions as a tool to communicate with the person. The ludic/emotive channel emphasizes exclamations, interjections, and allows expressing one's desires and urges, with immediate reactions without thinking them twice. The fostering channel allows sharing one's emotions and feelings with the interlocutor in a close, warm, and caring way. These channels refer to both the used words and to the non-verbal part of communication (gestures, mimic, tone of voice). This study aims to characterize the brain regions involved in the response to the different channels of communication.
