Chapter 5 Research Methods in the Study of Abnormal Behavior Science and Scientific Methods science the pursuit of systematized knowledge through reliable observation Testability and Replicability - a scientific approach requires 1 that propositions and ideas be stated in a clear and precise way - statements, theories, and assertions, regardless of how plausible they may seem, must be testable in the public arena and subject to disproof - closely related to testability is the requirement that each observation that contributes to a scientific body of knowledge be replicable or reliable - whatever is observed must be replicable; that is, it must occur under prescribed circumstances not once, but repeatedly - if the event cannot be reproduced, scientists become wary of the legitimacy of the original observation The Role of Theory theory a formally stated and coherent set of propositions that purport to explain a range of phenomena, order them in a logical way, and suggest what additional information might be gleaned under certain conditions I.O.W. a theory is a set of propositions meant to explain a class of phenomena - a primary goal of science is to advance theories to account for data, often by proposing cause-effect relationships - a theory permits the generation of hypotheses to be tested in research hypothesis the specific prediction about the outcome of an experiment; it is based on the assumption that the theory in question is accurate I.O.W. hypotheses are expectations about what should occur if a theory is true - the generation of a theory is perhaps the most challenging part of the scientific enterprise - theories are constructions put together by scientists; in formulating a theory, scientists must often make use of theoretical concepts, unobservable states or processes that are inferred from observable data - a theoretical concept, such as acquired fear, is useful in accounting for the fact that some earlier experience can have an effect on current behavior - theoretical concepts can be linked to several different measurements, each of which taps a different facet of the concept - theoretical concepts are better defined by sets of operations that by a single operation The Research Methods of Abnormal Psychology - all empirical research entails the collection of observable data - there are many research methods in the study of abnormal behavior; the methods vary in the degree to which they permit the collection of adequate descriptive data and the extent to which they allow researchers to infer causal relationships The Case Study case study the collection of historical or biographical information on a single individual, often including experiences in therapy www.notesolution.com
