Which of the following statements about interactionism is true?

Interactionism is a philosophical concept that emphasizes a reciprocal relationship between the mind and body, positing that both can influence one another. The notion that there is a two-way interchange is a central tenet of interactionism. For instance, this perspective supports the idea that mental states (such as beliefs or desires) can affect physical states (like bodily responses), and vice versa.

In contrast, the other options reflect misunderstandings of interactionism. The assertion that the mind does not influence the body negates the core principle of interactionism. Proposing a "perfect synchrony without interaction" misrepresents the interactionist view, as it implies that the mind and body operate in isolation instead of engaging in a dynamic relationship. Lastly, claiming that interactionism is the same as psycho-physical parallelism disregards the fundamental differences between the two concepts, where parallelism suggests that mental and physical processes run parallel but do not influence each other, differing significantly from the interactionist perspective.
