Oct52003 CHANAPS Notes From Reading C HAPTER2: THE R ESEARCH ENTERPRISEIN PSYCHOLOGY CHAPTER 2 Looking for Laws: The Scientific Approach to Behavior - As scientist, psychologists assume that behavior s governed by discernible laws or principles. Goals of the Scientific Enterprise 1) Measurement and description 2) Understanding and Prediction 3) Application and Control. Measurement and Description - Sciences commitment to observation requires that an investigator figure out a way to measure the phenomenon under study. - Develop measurement techniques that make it possible to describe behavior clearly precisely. Understanding and Prediction - Scientists believe they can understand events when they can explain the reason for occurrence of the events. - Hypothesis- tentative statement about the relationship between two or more variables. - Variables- any measurable conditions, events, characteristics or behaviors that are controlled or observed in a study. Application and Control - Scientists hope that they information they gather will be of some practical value in helping to solve everyday problems. - Once people understand a phenomenon, they often can exert more control over it. Theory- system of interrelated ideas uses to explain a set of observations. - By integrating apparently unrelated facts and principles into a coherent whole, theories permit psychologists to make the leap from the description of behavior to the understanding of behavior.
