Step 1: Understanding the Concept:
Psychological attributes are traits that vary from person to person and influence their behavior.
Interest is a preference for a particular activity or a liking for engaging in it. It is primarily driven by personal satisfaction and enjoyment.
Aptitude, on the other hand, is an individual's potential or underlying capacity to learn a specific skill or perform a certain task with training.
One can have high interest in an activity even if they have low aptitude for it, and vice versa.
Step 2: Detailed Explanation:
In the case of Ananya, the question provides specific indicators to help classify her attribute:
- She sings and plays the guitar "whenever she is free," which indicates a voluntary preference.
- The phrase "although she is not a great singer" explicitly tells us that her performance level or skill is not high. This suggests she might not have a high musical aptitude.
- Most importantly, the text says "her spirits lift when she sings along." This describes the emotional reward and psychological well-being she derives from the activity.
Analyzing the options:
(A) Aptitude: If the text said Ananya was a natural at music or could learn any song in minutes, this would be the answer. Since she is "not a great singer," aptitude is not the attribute being highlighted.
(B) Personality: This refers to the overall pattern of characteristics. While singing might be a part of her lifestyle, "Interest" is the more specific psychological term for liking an activity.
(C) Interest: This perfectly fits the scenario. Interest is defined by engagement for pleasure rather than for demonstrating skill.
(D) Intelligence: This refers to her general cognitive capacity (which she likely uses for her medical studies), but her singing hobby is a matter of personal preference, not a measure of her global intelligence.
Step 3: Final Answer:
Ananya's singing is a leisure activity that provides her with emotional joy and satisfaction.
Since the motivation is liking and enjoyment rather than skill or potential, the attribute is Interest.
