Context Embedded Perception (CEP): A New Stem of the Verifiability Approach
The goal of this project is to develop a within-subject indicator of deceptive strategies to assess the veracity of utterances. We suggest that the qualitative differences between perceptual and contextual details can serve as a potential generator of deception strategy. While perceptual information is actually experienced and acquired directly by the senses, contextual information is virtual in its nature and based on semantic knowledge and relative conceptualizations. The contextual attributes are imposed on the perceptual details and frame them in time and space. Obviously, the truthfulness of perceptual details can be checked only when they are embedded in the context of time and space. Thus, the contextual details are those that confer the status of verifiability upon perceptual details. Based on those assumptions we are in process of establishing the Context Embedded Perception (CEP) measure to determine the veracity of provided utterance.
