For the HUMAN PARTICIPANTS STUDY, address the following points:
1) Begin by citing the article using author(s) last name(s) and year of publication, and
providing a brief introductory statement. A hypothesis is an educated guess that the researcher
makes before completing the study about what he or she will find. What hypotheses or research
question do the researchers have in regard to the study? What are the basic points that the
researchers use to support the formation of the hypothesis?
2) Clearly indicate what behavioral phenomenon is being studied and show that you
understand the phenomenon by defining it.
3) A population is the large group of all people to whom the results of the study would apply.
For example, if I did a study using 100 healthy babies and their mothers looking at the relationship
that develops over the first year of life, my population would be all healthy babies with mothers.
If I do a study about 50 pregnant high school students to see what effect the pregnancy has on
academic performance, my population would be all girls who become pregnant during the high
school years. What would the population be for the study?
4) A sample is the group of people who actually participated in the study. In the above
examples, the 100 healthy baby/mother pairs are the sample, and the 50 pregnant high school
students are also a sample. For your study, identify the sample, including number of participants,
and distribution of males and females. Tell me two additional things about the characteristics of
the people who make up the sample. Evaluate how well the sample represents the population of
interest. Explain your answer. Note that the preferred term for humans is “participant” even if the
researchers use “subject” in the article.
5) Identify the manipulated independent variable(s), and the measured dependent
variable(s in the study. Indicate any variables that are being controlled by the researchers.
Identify the research design and briefly describe the research procedure. Address any procedural
concerns that you might have about the research design. What are the ethical issues that might be
raised for this study and how are they addressed by the researchers?
6) What are the results of the study? Do they support the researcher’s original hypothesis,
or provide a clear answer to the original question? Why or why not? Suggest a potential follow-
up question for future research. NOTE: Do not use terms such are prove, disprove, proof, truth,
or true in referring to the meaning of research results. A single study does not establish proof or
truth.
