Which of the following sequences best reflects the order of events in a typical experimental session?
Suppose a researcher studying social anxiety in children uses a measure of “fidgeting” that indexes hyperactivity instead of social anxiety.
What type of validity is this measure lacking?
In order to maximize the likelihood that experimental and control groups are similar before any treatment is begun, researchers typically use:
Researchers are likely to choose a correlational design when:
In correlational studies, we cannot interpret which variable may be the cause and which variable may be the effect. This phenomenon is known as:

Another word for replication is:
Scientists conduct , which involves the careful and systematic collection of data.
The values in a data set span from 60 to 90. If a researcher knows this, then the researcher is aware of the:
One criticism that is made of many experimental studies in psychology is that:
Based on your text’s discussion of scientific inquiry, the goals of psychological science include each of the following EXCEPT
behavior and mental processes.
What does it mean for a theory to be falsifiable?
What do we mean when we say that inferential statistics allow researchers to make generalizations?
How do theories reflect the law of parsimony?
Psychologist Jean Piaget observed children to see how they solved problems. Over the course of many studies, he was able to spot general patterns of behavior. This led him to connect different concepts and behaviors within a single:

In which of the following ways are conducting research with humans versus animals different?
A researcher believes that presenting possible suspects in a lineup one at a time instead of in a group would lead to more accurate identification of the true suspect. This belief represents a(n):
In scientific research, a researcher’s expectations about a study can lead to systematic errors in observation. This phenomenon is called:
In what way are a scatterplot and a correlation coefficient similar?
Jafar conducted an experiment with student participants enrolled in his PSY 101 class. He investigated their reactions to advertisements that used humor. When analyzing his results, he should take into
The systematic recording of overt behavior of human and nonhuman animals in their natural environment involves what research
A researcher studying attention-deficit/hyperactivity disorder is gathering information on how many children receive an attention-deficit/ hyperactivity disorder diagnosis each year. Which of the four primary goals of science is she addressing?
Something that can be measured or manipulated by an experimenter is considered:
According to your text, variables, by definition, can:
If a researcher created two groups by assigning the first 30 people to the experimental group and the last 30 to the control group, the process would violate the principle of:
Bai is conducting a study on learning. When she manipulates an independent variable, it is possible that some other factor, such as noise in the hall, can affect learning in one of the groups but not in the other. This possibility reflects the presence of:
When researchers study multiple groups and report the means for each group, they are reporting:
If a researcher wanted to study the behavior of protesters who were in a closed group and did not easily admit new people, the researcher would probably use which of the following approaches to study
One of the four main goals of science is explanation. The main goal of scientists addressing this goal is to explain:
A research team told one group of people it would hear a set of jokes that were funny and a second group that it would hear jokes that were not funny. A third group was not told anything about the jokes. The jokes in all conditions were the same. Research with this design is:
When a researcher joins a social group and talks to the members in order to study that group, the approach is referred to as:
Casey is using statistical techniques to examine whether children with autism differ in the amount of self-esteem they report as compared to children without autism. She finds a significant difference, which suggests that the results of her analysis:
When two variables are correlated, it is not clear which one is a causal variable and which is an effect. This ambiguity reflects:
The variable that a researcher manipulates in an experiment is called the:
If a researcher believes that participants in a single group will score differently from one another on a task, the researcher can find out if that is true by looking at the:
Philippe wants to study the number of times that close friends touch each other in their interactions. His interpretations of this behavior would need to take into consideration:
In which of the following types of study do researchers examine the extent to which variables are naturally related in the real world (that is, there is NO attempt by the researcher to influence the relation among the variables)?
How are a theory and a hypothesis different?
Which of the following best represents a medium negative correlation?
Data collection is particularly problematic when a researcher uses participant observation because:
Which of the following statements is true of serendipity in science?
