Benefits and risks of cannabidiol? 9) What are the study's recommendations for minimizing risk? 10) What might be some limitations in generalizing the results of this s

Explanation / Answer

1. This was a naturalistic study because the participants were tested on memory and psychotomimetic symptoms when they were intoxicated by their own chosen marijuana, rather than having it administered by the experimenter.

2. The main challenge associated with a naturalistic study is that the independent variable cannot be manipulated by the experiments and can only be controlled through the process of selecting existing variables.

3. The somatic and behavioural variables in the study were memory and psychotemimetic symptoms.

4. Verbal memory was measured using the prose recall test and episodic memory was assessed using the source recall test.
