1. Introduction to Research What is behavioral research, and why it is conducted? What are the limitations of “everyday science” and intuition for understanding behavior? What is the scientific method and why do scientists use it? What is the difference between a fact and a value, and how do a scientist’s values influence his or her research? What are the goals of basic research and of applied research, and how do the two types of goals relate to each other? What benefits are there to be gained from learning how to evaluate research, conduct it, and think critically about it? What are the goals of descriptive, correlational, and experimental research? What are the advantages and disadvantages of each research approach? Behavioral Research: The goal of behavioral research is to discover, among other things, how people perceive their world, how they think and feel, how they change over time, how they make decisions, and how they interact with others. The statement made by behavioral researchers are empirical, which means that they are based on systematic collection and analysis of data, where data are information collected through formal observation or measurement. Why is behavioral research important? Increase our understanding of behavior. e.g. Autism • Provide methods for improving the quality of our lives. e.g. Racism, Sexism, Ethnocentrism Provide important information that complements other scientific approaches. e.g. social aspects of death as opposed to medical research Demonstrate the full range of capacities humans possess How do we understand our everyday behavior? Relying on our intuition. But do we really understand the reason of our behavior? Example. Nisbett & Wilson (1977) We can not get accurate information by simply asking people why they do what they do. Often provide valuable Insights about human behaviors. Why is it problematic? 1. We easily use intuition to understand human behaviors (or concepts). • Intuition makes the behavior seem natural • If they seem so natural to us, we take them for granted . 4. If they are taken for granted, we are not aware why the behavior is being performed. 5. Therefore, we can’t assess the reason for the behavior which is what we are really trying to understand. Scientific Methods What is the scientific methods? Being Objective 1. Free from the personal bias 2. Free from the investigator’s emotions 3. Replicable by others (scientists) 4. Open to other’s (scientists)’s scrutiny. Values Personal statements such as “abortion should not be permitted in this country”, “Good people will go to heaven when they die”. Facts Objective statements determined to be accurate through empirical study such as “there were over 20,000 homicides in the United states”. Scientific Methods Observing everyday behavior carefully. Drawing inferences from the observation. Constructing hypotheses or comprehensive theories . Choosing the best methods to prove your predictions. Analyzing the collected data and objectively interpret the data. Replicating the findings to generalize the findings. Basic Research It investigates fundamental questions about behavior without particular reason to study except to acquire a better knowledge of how these processes occur. e.g. memory for pictures, nerve impulse. It provides underlying principles that can be used to solve Specific problems. Applied Research It investigates issues that have implications for everyday life and provide solutions to everyday problems. e.g. what types of psychotherapy are most effective in reducing depression. It gives ideas for the kind of topics that basic research can study. The importance of Studying Research Methods •Evaluating Research Reports •Conducting Research •Thinking Critically about Research Behavioral Research Descriptive Research Survey & Interview Correlational Research Naturalistic Observation Converging Operations Experimental Research Research Descriptive Research Correlational Research Experimental Research Methods Strengths Drawbacks Allows capturing the complexities of everyday behavior. It provides a relatively detailed picture of what is occurred at a given time. Limited to providing static picture. Cannot answer how a certain behavior develops, what impact the behavior has, and why the behaviors was performed. Systematic Relationships among variables Pearson r correlation coefficient Allows testing of expected Relationships between and among variables and making of predictions. Cannot be used to identify causal relationships among the variables. Remains a possibility that some other variable caused the observed variable to be correlated. Causal relationships of more than two variables ANOVA MANOVA It allows drawing of conclusion about the causal relationships among variable. Cannot experimentally manipulate many important Variables.
