Which motivation theory centres on the idea that people are driven to engage in activities to develop or demonstrate their skills?

Competence motivation is a theory that centers on the idea that people are driven to engage in activities to develop or demonstrate their skills. If someone successfully performs a challenging task and receives praise from family or peers for it, then they will experience a belief in their competence in that achievement domain. This theory was given by Susan Harter which suggests that people (in her case, she was specifically referencing children) will move toward activities they feel a greater competency in and shun subjects that are more challenging. She developed an instrument, called the 'Perceived Competence Scale for Children,' which distinguished areas of competence. The scale has four domains : ·         physical, ·         cognitive ·         social ·         Self-worth
