Exam 2: Research Methodology

Before psychologists can begin a research project, they must receive approval from:

Researchers investigated whether mood affects participants' ratings of jokes. Participants in the first mood group read sad statements. In the second group, participants read neutral statements. In this study, the participants who read the sad statements constituted the:

Researchers have used driving simulators to investigate whether talking on a cellphone impairs the ability to drive. The published studies show that using a cellphone has a detrimental effect on attention to driving. One valid criticism of these studies is that:

Lily is studying a participant's arousal level when watching a violent video. She is likely to use:

When confounds are present in an experiment, they result in:

A researcher would be likely to use a reaction time study in order to see how quickly mental processes proceed when a person solves a problem. Reaction time is an example of:

If a researcher wants to see how quickly a person can process complex information, that researcher is likely to use:

If a researcher wants to assess participants' feelings at various times during the day and in many different locations, a useful methodology would be:

Students who study a little for tests tend to make more errors on tests; students who study a lot, tend to make fewer errors. If a researcher collected data on such test scores, she would likely spot:

Jamal wants to find out whether the customers of his coffee shop prefer that he add booths or keep his tables and chairs. A researcher would be likely to use what kind of study to help him?

A limitation of EEG recording in brain research is that:

Dr. Lasagna tests a new diet. Overweight adults are weighed and placed into one of two groups so that the weight of the groups is equal to start with. One group of adults is given the new diet and the other is placed on a waiting list. After three months, Dr. Lasagna observes that the group on the new diet weighs less. In this example, the independent variable is:

When two variables are correlated, it is not clear which one is a causal variable and which is an effect. This ambiguity reflects:

A study of the experiences of a person with an extremely rare brain disorder is likely to make use of:

Dr. Bloomin wants to investigate the impact of talking to plants on their growth. He decides to talk to a group of 40 tulips each day for six weeks. A second group is not talked to at all. After six weeks he discovers that the tulips he talked to are five centimetres taller than the tulips not talked to. This study is best described as:

If a researcher wanted to study the behaviour of protesters that were in a closed group and did not easily admit new people, the researcher would probably use what approach to study them?

If you want to know how far apart scores in a data set tend to be, you could use the:

Researchers assess the baseline performance of people with respect to a given behaviour so they can identify what happens to behaviour when they manipulate a variable. The use of baseline groups and groups that experience a manipulation of a variable is characteristic of:

Researchers are likely to choose a correlational design when:

The most basic principle of research set forth in the Nuremburg Code is:
