This document discusses interests and how they develop in children. It notes that interests have both subjective and objective aspects, with the subjective focusing on feelings and the objective on observable behaviors. Interests are generated through three types of learning - trial and error, identification with admired people, and guidance from others. A child's interests can be identified by observing their activities, questions, conversations, reading materials, drawings, wishes, and self reports. The document also states that all individuals have both inborn and acquired interests that show individual differences.
