Why do researchers in the area of mental imagery need to be concerned about experimenter expectancy?
a. Experimenters might somehow convey their hypotheses to the participants.
b. Experimenters typically expect participants to perform very well on imagery tasks.
c. When experimenters expect a certain outcome in their research, the participants unconsciously produce results that contradict this expectancy.
d. Experimenter expectancy typically increases the magnitude of individual differences.
Question 2Psychologists have studied how deaf individuals perform on mental rotation tasks when they are fluent in American Sign Language. The research shows that these individuals:
a. make more errors than people who use spoken communication.
b. make fewer errors than other people, because they are accustomed to viewing a scene from a different perspective.
c. make fewer errors than other people, because they are not distracted by various sounds in the surrounding area.
d. make the same number of errors as other people.
Question 3Suppose that you are reading an article about visual imagery. The researchers point out that experimenter expectancy might have influenced the results of this study. One example of this possibility would be:
a. the participants tried to ruin the researchers' results by refusing to follow directions.
b. the participants tried to answer as quickly as possible, so they could leave early.
c. the researchers' expectations could have influenced the participants' responses.
d. the researchers used a heuristic when trying to explain the results of this study..
