Course Format Lectures on Monday and Wednesday
Given by me (Dr. Cutting) Overview of the main issues in research methodology
Exams (3) are in the lecture sections (45%) Class research project (15%)
Labs on Thursday or Friday (depending on your section) Given by your TAs
• Charles Coey (sections 02 & 04)• Andrew Monroe (sections 03 & 05)
“Hands on” experiences with research In-lab exercises (15%) Group research project (15%) Journal exercises (10%)
Why take research methods?
“Because it is required”
Other good reasons: Psychology is a science You may need to conduct a study Reading and evaluating other studies Making decisions in your daily lives Become a “better thinker”
Course Objectives
Basically the "nuts and bolts" of putting together and completing a research project in psychology. Learning to review the primary literature
Getting a research idea Development and execution of a research plan
Basic analysis of research results. Presentation of the results
Course Requirements 3 Exams (45%)
Each is cumulative. Each exam will be worth 15% of your final grade.
Homework exercises (10%) 2 journal article summary assignments
Lab Assignments (30%) Lab exercises (15%) Lab Group research project (15%)
Research project (15%) Project Proposal (5%) Final APA style manuscript(10%)

Exercise: How do we know?
Write down two things that you “know”.
Write down HOW you “know” those things.
Methods of Inquiry Type of knowledge
Objective - having “real” existence outside of a person’s mind
Subjective - existing in a person’s mind
Ways of knowing Analysis - finding supporting evidence
Acceptance - taking as true

Methods of Inquiry The scientific method
A method used to test and analyze claims about behavior
Uses scientific methods of systematic observation and experimentation.
Scientific Method write down two generalizations that you have observed about people’s behavior.
Step 1: Observation Pay attention to the world around you, look for generalizations
Two kinds of generalizations• Descriptive generalizations – just describe how it is/what was seen, without making predictions
• Cause and effect generalizations – makes predictions about the observed relationship between two (or more) things.
Scientific Method Step 2: Develop a theory or hypothesis An explanation for the observed behavior(s)• May be based on past research, common sense, intuition, logic, etc.
Scientific Method Step 3: Generate a testable prediction Need to specify how your hypothesis can be tested.
Falsification is at the heart of the scientific method• More on this next lecture
Scientific Method Step 4: Make systematic observations Observational and experimental methods
• What are the relevant variables?• How do we measure the variables?• What needs to be controlled?
Much of the rest of this course deals with these
Scientific Method Step 5: Evaluate your evidence
Refutes theory Supports theory Leads to the revision of the theory Consider alternative theories
Psychic watch repair Uri Geller, famous psychic. In Australia (and other places), would “heal” watches in audiences and even over radio.
How did he do it? Geller’s claim: Psychic energy from him.
Psychic watch repair Problem:
Someone else replayed tape of the broadcast and found it worked then too
Alternative explanation: Old watches usually not working because oil gummed up. Heat of hands is sufficient for a short time.
Experimental Solution: Add a control group
