“…First, does the word "paradigm(s)" fit the "schools of thought" in a proper sense? The answer is largely controversial, and some authors have fairly proposed to use the word "sub-discipline" instead (Friman, Allen, Kerwin, & Larzelere, 1993), a suggestion that has been adopted by other studies in this field alongside the term "school" (Robins, Gosling & Craik, 1999;Tracy et al, 2005;Norcross, Karpiak & Santoro, 2005;Spear, 2007). Here, we will use the word "approach", "theory" or "trend" because the term "sub-discipline" or "school" might implicitly suggest that these views are completely incompatible with each other when they are not.…”
