Clinical Psychology Vocabulary Practice Test

What term describes a lack of emotional responsiveness often observed in some mental health conditions?

Apathy Flat affect Anhedonia Blunted affect

Correct Answer:

Flat affect

Explanation:

Emotional expression is observed as affect—the outward display of emotion through facial expression, voice, and gestures. When that expression is essentially absent or severely diminished, we call it flat affect. This term captures the noticeable lack of emotional responsiveness clinicians look for in some mental health conditions, even if the person’s internal feelings might differ. Among the options, flat affect uniquely describes this complete or near-complete reduction in outward emotional display. Apathy is about motivation and drive, not the expressed emotion. Anhedonia refers to not enjoying activities, not to how emotions are shown. Blunted affect means reduced expressiveness but not to the point of being nearly absent, so it’s less extreme than flat affect.
