The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases. Therefore, motivation be optimized at medium levels (Olson & Hergenhahn, 2013). Modern day relevancy in evolutionary psychology as far as education exists and remains relevant today. Given the innate human predisposition to acquire language, for example, schools should stress bilingual learning even in the early stages of education (Olson & Hergenhahn, 2013). Evolutionary psychology certainly remains relevant in psychotherapy today. It is important for therapists to be familiar with human development over the years and to truly understand why people are the way they are and why they behave the way they do in different situations and in different environments.
