Catharsis

From the Greek for cleansing; Aristotle used it for what tragedy achieves through pity and fear, and commentators have read it as purgation, purification or clarification. Breuer and Freud turned it into a clinical method of emotional discharge, and empirical psychology turned it into a testable claim that expressing an emotion reduces it. On this site catharsis means a subjectively felt release of emotional tension after expression, exertion or immersion, without any assumption that the cause of the tension has changed.

Where the site uses it

Studies behind it

The works the definition rests on, with the level of evidence each was appraised at.

  • Aristotle (c. 335 BCE). Poetics.

    Level E Classical text

  • Breuer, J., & Freud, S. (1895). Studien über Hysterie [Studies on hysteria].

    Level E Book

    Supports historical claims about the cathartic method and abreaction. Uncontrolled case reports cannot show whether the method was effective.

  • Pennebaker, J. W. (1997). Writing about emotional experiences as a therapeutic process. doi:10.1111/j.1467-9280.1997.tb00403.x

    Level D Review
