PSY/335 Week 2 Team Assignment Proposal Worksheet

Complete the University of Phoenix Material: Proposal Worksheet.

Each member of the team chooses an article from a journal in the university library (see below) and answers the 4 questions in the Proposal Worksheet document. Then everyone in the team reviews the other members' submissions of answers 1-4 for each of their articles. After reviewing each team member's submission, answer the following two questions as a team:

1. What is your research question?

2. What is your hypothesis?


Now here's a final note for everyone to keep in mind: decide on a topic that the team wants to find these research study articles on because the team will choose one of the subjects that you will have presented in the Week 2 proposal worksheet to focus on for the Methods Paper due Week 3. Using one of the research questions and hypothesis you all agreed on in Week 2 for this subject, the team will create your own imaginary study around the subject, and then write the paper during Week 3.


The team will then submit a paper that includes each team member's article review (the four questions answered with the article citation) and the team answers to the two questions.

NOTE: The articles you choose must be articles in journals in the University's library. Those are the only articles that qualify for this assignment.

                                             Proposal Worksheet

Each team member will pick an article for this worksheet. Replicate these set of questions for each team member for this worksheet.

Team member name:

Citation of article:

1. What is the author’s goal?

2. What questions remain unanswered?

3. If I had to design an experiment to test this hypothesis, what would I do?

4. What are the independent, dependent, and control variables?


After reviewing each team member’s submission, answer the following questions as a team:

1. What is your research question?

2. What is your hypothesis?

Read the following scenarios and match each scenario with the correct type of experimental design.

1.      _____ Two classes of children are studied regarding the effects of a new teaching method in science.  One group received the new method of instruction, while the other group uses the standard, traditional method of instruction. Both classes are measures for achievement before and after the teaching methods.

2.      _____ Divide your subjects in half.  One group receives one treatment of the independent variable and the other group receives a different treatment of the independent variable. Subjects were all told they were going to see a video of a therapist's session after which they would rate the quality of the session. The groups differed in that the subjects in one group were told that prior evaluations indicated that the therapist was effective whereas subjects in the other group were told that the evaluations indicated the therapist was not effective. These different subjects were used for the two levels of the independent variable: subjects were in either the "effective therapist" or the "ineffective therapist" condition.

3.      _____ All subjects perform at all levels of the independent variable.  Subjects diagnosed as having attention deficit disorder were each tested on a concentration task after receiving medication. All subjects were tested four times, once after receiving one of the four doses. Each subject was tested under eachof the four levels of the independent variable-dose of medication.

4.      _____ A small group is measured for the amount of anxiety they experience in math class (baseline).  They are taught a relaxation method and measured again to measure anxiety in math class.

5.      _____ To study verbal commands in canines, during week 1 the baseline is recorded for how many times a dog chased a cat.  During week 2, dog was verbally scolded (treatment) when the dog chased the cat, and the chasing behavior was recorded.  During week 3, the chasing behavior was recorded without the verbal scolding (treatment).
