Stimulus

Many uses have been claimed for hypnosis, from combating drug addiction to overcoming common phobias. A recent experimental study helps illuminate the supposed connection between hypnosis and increased power of recall. A number of subjects listened to a long, unfamiliar piece of instrumental music. Under subsequent hypnosis, half the subjects were asked in their movie recollections as the subjects in the first group were in their music recollections.

Answer choices

  1. Too Strong: many4% picked this

    Many of the claims made on behalf of hypnosis

    One claim made on behalf of hypnosis seems to be that "supposedly hypnosis leads to an increased power of recall". We could probably say that this claim is undermined by the results of this study. Half the subjects "remembered" scenes from a movie they never saw, so that doesn't sound like improved recall. "Many" doesn't have a precise quantitative beginning, but it's safe think "at least 5". One example is definitely not enough to justify "many". America has only had one President who was a reality TV star, and so it would be untrue for us to say "Many US Presidents have been reality TV stars".

  2. Too Strong: cannot8% picked this

    Hypnosis cannot significantly increase a person's power

    We definitely have some evidence that hypnosis's connection to recall is weird. It seems to have created false memories in the people who were asked about the movie they hadn't seen. But it's still possible that certain forms of hypnosis, in certain circumstances could significantly increase a person's power of recall. Maybe hypnosis has the power to elicit harder-to-reach "true" memories, if a person is asked the right sort of question (and it has the power to elicit "fake" memories, if a person is asked a misleading sort of question). If no other answer had better support, then we could call this the Most Supported answer because it has some support, but it's hard to say just from this one study that hypnosis cannot do [ _____ ] .

  3. Too Strong: inevitably10% picked this

    Recalling events under hypnosis inevitably results in

    This falls into the same bucket as (C). We know that within this study, some false memories were created, but it's too strong to say from this one study that this always happens; it's inevitable; it cannot be otherwise.

  4. Correct74% picked this

    What people recall under hypnosis depends to at least some extent

    Why this is right

    This is more softly-worded then other answers, so it's easier to support. Do we have any evidence that suggestion can play a role or have an effect on what people recall under hypnosis? Sure! People recalled scenes from a films they never saw. Since they didn't see any film, the question posed by the researchers suggested to them that they had seen a movie. It may even be that the music piece they heard suggested certain emotions or feelings that the hypnotized people recalled as though they were scenes from a movie. If what hypnotized people recalled wasn't affected in any way by suggestion, then it would be pretty unthinkable that people who were asked about the movie would start talking about a movie they never saw. There is an annoying aspect of this answer to me that may have troubled some students --- is it improper to say that you're recalling something, if it's a false memory? It almost feels like this answer should have been written as "what people claim to recall under hypnosis". But given how extreme the other contenders are and how soft and provable the wording here is, this is still our safest pick.

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

  5. Unsupported Comparison4% picked this

    Visual memory is enhanced more by hypnosis than is

    This study only featured hypnotized subjects trying to remember auditory memories. There were no visual memories they were being tested on recalling. We couldn't possibly support such a sweeping broad comparison from this one study that hypnosis has more effect on visual memory than on auditory memory.
