The term 'anhedonia' is most closely associated with which of the following concepts?

Anhedonia refers to the inability to experience pleasure or a loss of interest in activities that are typically enjoyable. This concept is often discussed in the context of various mental health disorders, particularly depression, where individuals may feel a pervasive sense of despair that diminishes their enjoyment of life. By definition, anhedonia specifically highlights the lack of pleasure, making it directly associated with this concept.

The other options do not align closely with the meaning of anhedonia. Fear relates to emotions that arise in response to perceived threats, guilt pertains to feelings of remorse or responsibility for wrongdoing, and energy refers to the physical or mental capacity to perform activities. None of these options capture the essence of what anhedonia represents, which is fundamentally about the absence or inability to experience pleasure.
