Answer:
The correct answer is Introspection
Explanation:
From the given question, from the history of psychology, we can asses Dave's claim using what is called Introspection
Introspection refers to the training of participants to report elements of specific sensory experiences.
Introspection is also the scrutiny of one's personal  feelings and conscious thoughts.

I don’t know what type you need but you could watch if you have Netflix the docuseries evil genius, when they see us, murder to mercy: the cyntoia brown story, worlds most wanted, or the social dilemma. For school I would probably watch the social dilemma because it’s more of a current thing that you might be able to relate to more and explain it more thoroughly. But if you go under the documentary genre on Netflix there are so many more to choose from. All the examples I listed are on Netflix but you might be able to find some of them on websites like myflixer.to if you don’t have Netflix.
