Stimulus

Psychologist: Some psychologists mistakenly argue that because dreams result from electrical discharges in the brain, they must be understood purely in terms of their physiological function. They conclude, against Freud, that dreams reveal nothing about the character of the dreamer. But since dream content varies enormously, then even if of dreams, they cannot completely explain the phenomenon of dreaming.

    It is used to support the author's conclusion, not the psychologists' conclusion. The "But" pivot signals that we have switched from talking about the psychologists ("They conclude") and are now hearing the author's thoughts. The author is using this premise as part of his attempt to undermine the anti-Freudian psychologists.

    According to this answer choice, somewhere in this paragraph we read, it says: a fully satisfactory account of dreams must allow for the possibility of their revealing significant information about the dreamer. We don't have anything like that. The closest we have is electrical discharges are not a fully satisfactory account of dreams because they don't explain the fact that dream content varies a ton.

  3. Bad Conclusion Match12% picked this

    It is used to suggest that neither Freud’s theory nor the theory of anti-Freudian psychologists can completely explain

    In reality, it is used to suggest that "electrical discharges cannot completely explain the phenomenon of dreaming", which is used to suggest that "psychologists are mistaken to argue that dreams must be understood purely in terms of their physiological function". Freud is not part of the author's conclusion (or evidence). He's sort of an just an aside within this paragraph. If anything, though, we think that our author is probably in sympathetic agreement with Freud.

    Out of Scope: difficulty Bad Conclusion Match It isn't being used to say that a complete explanation will be difficult. It is just used to say that the psychologists' "electrical discharges" explanation is not complete.

    Why this is right

    This might not be what we predicted, but it seems like we can make it work. What is a claim that some psychologists use to argue against a view of Freud's? They argue, because dreams result from electrical discharges, dreams reveal nothing about the character of the dreamer. The author is saying, "if it's all just electrical discharges, then why does the content of the dream vary so much from person to person (and from dream to dream)? Even if dreams are caused by electrical discharges, the way they manifest uniquely in different people suggests that dreams do reveal something about the character of the dreamer." It seems like the claim the psychologists use to argue against Freud would be, "dreams must be understood purely in terms of physiological function", and the author is using this claim we're being asked about to undermine that claim.

    Skill tested: Role · how this choice captures the argument's function is the move to repeat next time.
