TEST THURSDAY!! Chapter Two Notes: 8/27/09 Research Methodology The Scientific Method Depends of Theories, Hypotheses, and Research -The four goals of psychological science are: 1. To describe (what) 2. To predict (when) 3. To control (what causes) 4. To explain (why) The Scientific Method: Theory - a useful theory will organize a wide range of observations and descriptive data; a good theory will follow some testable predictions Hypotheses - testable predictions; can reject or revise theory; done in advance to protect against biases Research - clearly define the VARIABLES (the things that you are measuring) also called operational definitions Operational Definitions - variables Data Analysis - the data drives the researcher, have to follow the data to make testable predictions Replication - good studies can be replicated by other individuals and still give the same results; the theory is supported and the data is replicated -One way we can learn to behave is by mimicking the behaviors of powerful others, if that is true than we can make more specific predictions. Example: kids watching aggressive films vs. kids watching exciting films but not aggressive. - CONFOUNDING VARIABLES : have to have only one variable, films both have to be exciting, but one has to be aggressive. What are the Three Main Types of Studies in Psychological Research? -There are three main types of studies in psychological research: descriptive, correlational, and experimental -Correlational : allows you to make predictions -Descriptive : observe and describe -Experimental : Causality, finding out the cause of something * Correlational and Descriptive don’t allow you to get at the cause of something Descriptive Studies -Researchers observe and describe naturally occurring behaviors to provide a systematic and objective analysis -Naturalistic observation and participant observation Observing is an Unobtrusive Strategy Don’t want to do anything that make the observee act differently Data collected by observation must be defined clearly and collected systematically Bias may occur in the data because the participants are aware they are being observed or because
