Cognitive psychologists say that we carry a model or personal image of the world, relationships and other concepts around with us. As the senses provide information we adjust this perception to arrive at cognitive consistency, (and resolve cognitive dissonance).
From a PR perspective the role public relations plays is in identifying the tokens and values within networks that have sufficient resonance with a person's perceptions (when they use their senses e.g. read something or hear something etc.) such that they pay attention. The PR process then has to offer tokens and values in an appropriate social frame which adds the campaign 'messages' to the understanding or personal model of the recipients. When this is done in such a way that both the organisation and the recipients gain an added value or understanding, the PR campaign will have been effective. Both parties will have a new understanding and new values. On the one hand the organisation will have gained an empathetic understanding and relationship with the recipients (publics) values and the recipients will better undestand the organisation and messages.
In participating with people's endless modelling and re-modelling of their internal view of the world, public relations, in the Relationship Value Model, adds values of interest and significance .
PR helps people understand the world.
