One-word substitution (personality and psychology): Identify the precise term for a person who is absorbed in his own thoughts and feelings rather than in external events or social interaction. Context: The focus is on inward orientation, self-reflection, and preference for one's inner world over outside stimuli. Instruction: Choose the best single-word substitute from the options.

Given data

• Description: One absorbed in personal thoughts and feelings more than in the external world.
• We must select the most accurate psychological term.

Concept / Approach
An introvert is a personality type characterized by inward focus, reflective thinking, and lower energy for large-group socializing. This distinguishes the term from labels that imply isolation or mere scholarship.

Elimination reasoning
Introvert — inwardly oriented; correct. ✅Scholar — educated/learned person; not necessarily inwardly focused. ❌Recluse — one who lives in seclusion; stronger social withdrawal than required. ❌Intellectual — values intellect/ideas; not inherently inward-looking. ❌

Verification / Example
‘‘He prefers quiet reflection to parties; he is an introvert.’’

Common pitfalls

• Confusing introversion with social anxiety or reclusion; introversion is about energy source and preference, not fear.

Final Answer
Introvert
