 Singhal's approach to E-E theory is based on works of Albert Bandura, specifically, the social learning theory and social cognitive theory.Singhal's work in E-E has investigated the dimensions of paradoxes, contradictions, and audience members' struggles in the process of media-stimulated change, a process involving parasocial interaction, peer communication, and collective efficacy.He notes that E-E has been successfully incorporated in hundreds of social change projects and as a field of communication research and practice, E-E "...continues to make richer, deeper, and wider connections with other social science and humanistic disciplines."
