Note: SC = Scandinavia, GE = Germany, SP = Spain, LA = Latin America, JA = Japan, CH = China, AU = Australia, NZ = New Zealand, AF = Afrique Noire (Sub-Saharan Africa), EG = Egypt. It should be noted that more recently developed psychologies do not have an especially strong linkage to early philosophers and psychologists, but instead take up the discipline at a later point in its history. Furthermore, some national psychologies are not rooted in Western epistemological tradition. Thus, some “new” and indigenous psychologists make less reference to key figures in their origins than do other national country disciplines (e.g., Afrique Noire, Egypt).
