Which of the following is NOT a clinically recognized name of a common phobia?

The term "sociophobia" is not a clinically recognized name for a common phobia. While the concept it implies—fear of social situations—does exist and relates closely to social anxiety disorder, it is not a formal term used in clinical settings. Instead, social anxiety disorder is the proper diagnosis used by mental health professionals to describe excessive fear or anxiety in social situations.

In contrast, zoophobia refers specifically to a fear of animals, agoraphobia is a well-established phobia concerning fear of open or crowded spaces, and alonophobia suggests a specific fear of being alone, which aligns with common definitions in the context of anxiety disorders. Thus, while the others are acknowledged phobias, sociophobia lacks the same recognition, making it the correct answer to the question regarding which is not clinically recognized.
