Final answer:
Saying "I earned an A on my psychology test" versus "My instructor gave me a C on my psychology test" exemplifies internal and external attributions.
Step-by-step explanation:
When someone says "I earned an A on my psychology test" versus "My instructor gave me a C on my psychology test," they are exemplifying internal and external attributions. In the first statement, the person is attributing their grade to their own effort and abilities, which is an example of an internal attribution. In the second statement, the person is attributing their grade to their instructor's decision, which is an example of an external attribution.
