“…According to Foshay and Moller (1992), HPT is an applied field, not a discipline; as such, its ''theory is likely to develop through the synthesis of models from cognate fields and underlying disciplines' ' (p. 708). Numerous authors have attempted to identify those particular cognate fields and disciplines-among them, Brethower (1995), Dean (1996), Dean and Ripley (1997), Foshay and Moller (1992), Gayeski (1995), Pershing et al (2008), Rosenberg, Coscarelli, and Smith Hutchison (1992), Schwen, Kalman, and Evans, (2006), and Sugrue and Stolovitch (2000). Although a wide variety of cognate fields have been postulated to be foundational to the HPT field, those most frequently cited are psychology, systems theory, organizational development, instructional systems design, and communications theory.…”
