Final answer:
Entity theorists generally adopt mastery goals; incremental theorists generally adopt performance goals.
Step-by-step explanation:
The correct options are: a. Mastery; performance.
Entity theorists believe that abilities are fixed and predetermined, so they tend to focus on demonstrating their performance and proving their abilities. They are more concerned with the outcome and the desire to look smart and successful.
On the other hand, incremental theorists believe that abilities can be developed and improved through effort and learning. They are more interested in mastering the material and acquiring new knowledge and skills.
