Exam 2: Research Methods in Psychology

In psychology,the definition of a behavior to be measured that is explicitly based on the procedures that will be used to measure the behavior is referred to as a(n)____________ definition.

Why do experiments allow conclusions about cause and effect relationships?

The small group of participants observed in a research study are referred to as the:

Five students had the following scores on a psychological test: 10,10,15,25,and 40.The median of these five scores is:

Double-blind experiments help prevent:

Participants in a study are sent to listen to a lecture either in a lecture hall filled with natural light or in a lecture hall with no windows and completely artificial light.Before leaving the lecture,they fill out a mood survey.What is the independent variable in this study?

The main difference between a correlational study and an experiment is that in a correlational study:

Correlations are useful for:

You believe that frustration causes people to drive faster.To test your prediction,you assign participants to two conditions.Group One participants are given 60 seconds to complete a task that cannot be completed in 60 seconds.Each subject is given 10 trials.Group Two participants read a simple paragraph and answer one question.Each subject is given 10 trials.Both groups of participants are then placed in driving simulators where their speed is monitored.In this experiment,the dependent variable is:

Scientists must hold the belief that behavior is at least somewhat predictable.

A researcher who uses a coding system instead of a study participant's actual name is sensitive to the APA ethical guideline of ____________.

Professor Lee needs to complete a research study.She has a very small budget,needs to cover a large number of participants,and needs to complete her research within three months.Which method would BEST meet her objectives?

When internationally known scientist Jane Goodall studies primates in Africa,she uses:

If students in Dr.Johnson's class want an "A," they must agree to be participants for Dr.Johnson's research project.Which ethical principle is being violated?

You cannot use the results of a correlational study to explain the causes of behavior.

Which assumption do all scientists make?

Professor Hornstein conducted a study that confirmed that children who play with toy guns commit more acts of aggression on the elementary school playground.Professor Kahey conducted a follow-up study and reached the same conclusion.Professor Wiggen's follow-up study did not reach the same conclusions.What can you conclude about Professor Hornstein's research?

In a formal experiment,the group that is NOT subjected to the independent variable is the ____________ group.

To determine gender differences in the play activities of young children,you might visit a preschool playground and use:
