Studying Behavior: 1 Chapter 2: Studying Behavior Scientifically Gathering evidence: 1. identify a question of interest 2. gather information and form a hypothesis 3. test hypothesis by conducting research 4. analyze, draw a conclusion, and report findings 5. build a body of knowledge ▯ ie. a theory A theory is a set of formal statements that explain how and why certain events are related to one another. A variable is any characteristic or factor that can vary. ▯ ie. people’s sex, height, GPA Since a variable can mean a variety of different things, we must give our variables an operational definition, meaning the specific procedures used to produce of measure the variable. Social desirability bias is the tendency to respond in a socially acceptable manner rather than according to how one really feels. Reaction time is how rapidly someone can respond to a stimuli. Unobtrusive measures are when researcher record behavior in a way that keeps participants unaware that certain responses are being measured. Archival measures are when researchers use records or documents that already exist. Descriptive research seeks to identify how humans and other animals behave in a natural setting. ▯ ie. case studies, naturalistic observation, and surveys Case Study: • an in-depth analysis of an individual, a group, or an event. • enables close studying of a given phenomenon. • can challenge the validity of a theory or belief. • may provide new ideas and hypothesis. • poor determiner of cause-effect relationship. • difficult time using case studies to generalize to different group of people since they are so specific. Studying Behavior: 2 Naturalistic Observation: • observation of behavior in a natural setting where the researcher avoids influencing behavior. • limited biases, with the exception of the own researcher’s bias in interpretation of information. • poor determiner of cause-effect relationship. Survey Research: • gaining information about a topic by administering questionnaires or interviewing people. • surveys a particular population, all the individuals we are interested in drawing a conclusion about, and a sample, a subset of individuals drawn from the larger population of interest. • representative sample: reflects the important characteristic of the population. • random sampling: every member of the population has equal chance of being chosen to participate. • efficient in gathering large amounts of data. • cannot determine the cause-effect relationship. Correlation Research: • examines relationships between two variables (scatterplots). • does not establish causat
