Answer:
John's positive self-concept
Step-by-step explanation:
Self-concept is generally considered as our internal perceptions of our actions, abilities and unique characteristics, a mental image of who you are as an individual. In other words, it is an overarching idea one has about who he or she is physically, emotionally, socially, spiritually, and in any other way. John's belief in himself that he is good with construction toys portrays his positive self-concept.
