PSY550 Wk3 – Informed Consent and Debriefing
PSY550 Wk3 – Informed Consent and Debriefing
Psychology students need the ability to create informed consent and debriefing forms that adequately state the purpose of studies to the participants in an ethical manner. In your capstone class (your last class), it is an expectation that you have a created a consent and debriefing form for your research proposal. It could be beneficial if you create this assignment around the topic you would like to research.
Before you begin the assignment, view the APA website and read the ethics listings.
Using the GCU Library, research consent and debriefing forms. Locate two to four scholarly resources to support your form.
Create an informed consent form and a debriefing form that explains the nature and true purpose of the study (students may adapt the examples from the textbook, see pages 76-77). Be sure to cite your sources at the conclusion of the document.
While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.
This assignment uses a scoring guide. Please review the scoring guide prior to beginning the assignment to become familiar with the expectations for successful completion.

How does the scientific method point towards truth? What is truth, and how do you know when you have found it?
PSY 550 Week 1 Discussion 2 Latest-GCU
Contrast deductive and inductive reasoning, and explain how they can each be used to generate a hypothesis.
PSY 550 Week 2 Discussion 1 Latest-GCU
Define reliability and validity in your own words. Briefly describe the different types of reliability and validity, including why it is important to conduct a study that is reliable and valid.
PSY 550 Week 2 Discussion 2 Latest-GCU
Stanley Milgram’s obedience to authority experiment is one of the most controversial studies in psychology’s history. Considering this example as well as others, critique such experiments from an ethical standpoint.
PSY 550 FINAL EXAM
Question 1
For each of the following examples, explain whether the researcher has made a correct decision or has made a Type 1 or Type 2 error. Explain why.
- Dr. G rejects the null hypothesis although the independent variable had no effect.
- Dr. R rejects the null hypothesis when it is false.
- Although the independent variable had an effect, Dr. E does not reject the null hypothesis
.Question 2
Explain the value of reversal designs (ABA designs) in single-case research.
Question 3
explain how a one-way analysis of variance works. How do you use between- and within-group variability?
Question 4
After watching nursery-school children, Ken Garoo wants to test the hypothesis that some toys are more fun to play with than others. He decides to compare “fun” toys (blocks) with “unfun” toys (stuffed animals). He also wishes to see if there is a sex difference, as well, so sex is added as an independent variable. A) What kind of design is needed? B) Diagram it out. C) Assuming 20 subjects are needed per cell, how many subjects are needed for this study?
Question 5
Bill Board is “lording” his SAT score over his friend, Rhoda Dendron, who took the ACT. “You only got a 25 in math,” he chortled, “while I got a 300 in math.” Given that the SAT has a ? of 500 and a ? of 100, and the ACT has a ? of 20 and a ? of 5, what is wrong with Bill’s logic (give the answer in both z scores and percentile ranks)
Question 6
Describe a two-matched groups design. How is the matching done?
Question 7
Chuck Wagon is very excited about the within-subjects approach. “Now I’ll never need to run large numbers of subjects again,” he says. However, Chuck has forgotten that within-subjects designs may be a) useless, b) impossible, c) confounded by order effects, or d) impractical when excessive subject time spent in an experiment makes data inaccurate. Give an example of each of these four objections.
Question 8
 A researcher has studied subjects’ ability to learn to translate words into Morse code. He has experimented with two treatment conditions: in one condition, the subjects are given massed practice; they spend 8 full hours on the task. In the other condition, subjects are given distributed practice; they also spend 8 hours, but their practice is spread over four days, practicing 2 hours at a time. After the practice, all subjects are given a test message to encode; the dependent variable is the number of errors made. The researcher has matched the subjects on intelligence. The results are in the following table. Decide which statistical test would be appropriate, carry out the test, and evaluate the outcome. Assume a significance level of .05 and that the direction of the outcome has not been predicted.
Question 9
Explain the pros and cons of longitudinal, cross-sectional, and sequential designs.
Question 10
Define the term quasi-experiment and discuss the pros and cons of this research method.
