Which term refers to channeling unacceptable impulses into socially acceptable actions?

Sublimation is the term that refers to the process of channeling unacceptable or potentially harmful impulses into socially acceptable and constructive actions. This psychological defense mechanism allows individuals to express their emotions and instincts in a way that is not only socially acceptable but can also be beneficial to themselves and society at large. For instance, someone with aggressive tendencies might take up a sport or engage in physical exercise to release those pent-up feelings constructively.

In terms of the other concepts: rationalization involves justifying one's behavior with logical reasons rather than emotional ones, which doesn’t involve redirecting impulses. Displacement involves shifting emotional responses from the original source of distress to a more acceptable object or person, but it does not transform the impulse in a constructive way. Suppression refers to consciously choosing to ignore or forget distressing thoughts or feelings, rather than redirecting them. Therefore, sublimation stands out as the correct answer, emphasizing the positive transformation of impulses into acceptable actions.
