* Research in Psychology as in all fields of science has two focuses of interest. * Basic Research = is concern with the quest for knowledge regardless of whether it has immediate practical value. * Applied Research = seeks to improve the human condition by discovering something that can be put to practical used. * When the scientist work, strive to find relationships between observable variables. For example, Robert Boyle found a direct relationship between the temperature of a gas and its volume under certain conditions. * By knowing one, the other can be predicted
* By manipulating one, the other can be controlled.
* But psychologists use several methods of relating variables to predict, control, and understand behavior. How do psychologist work? What methods do they use
* As with all science, psychology is interested in discovering a new information that can be verified by other researchers. The methods that psychologists use include: experimental method, observational, survey, test method and case histories. * Experimental Method = is the most widely used of scientific ways of getting information. The method can be used outside the Laboratory as well as inside under controlled conditions. * The experimental method is a matter of Logic, not of location * However, most of the experimentation takes place in “special laboratories” chiefly because * The control conditions commonly require special equipment that is best housed and used in one place. * Variable = one of the varying factors being studied in experimental or other research * Independent variable = this is the factor under experimental control to which the changes being studied are related because we change it independently * Dependent variable =depends on these changes under investigation. * The experimenter, before making any actual observation defines and analyzes the problem under consideration in what he...
