American psychologist who proposed the therine “Ambiversion” (see Ambivert in Chapter 1.5. Key Psychological Concepts in Differential Psychology). Conklin considered ambiversion to be a psychological norm. The scientist explained the absence of a term for people who are neither introverts nor extroverts by the fact that psychoanalytic terminology was developed, first of all, to describe pathologies. Conklin believed that, unlike the other two types (introvert, extrovert), the ambivert is healthy, flexible, adaptive, and effective.
