What is an example of science not being public?

Elsevier's subscription-based business model Institutions must PAY to access AND publish research

What are the 3 important principles of the scientific method?

Empirical (i.e., obtained by making observations) Public Objection

What differentiates science from pseudoscience?

Gathering evidence from careful, systematic, and objective observations 1) Testable and refutable hypotheses 2) Objective and unbiased evaluation of available evidence 3) Actively tests and challenges its own theories and adapts the theories when new evidence appears 4) Grounded in past science

A statement that describes or explains a relationship between variables

Hypothesis *A hypothesis can lead to several different predictions

What kind of reasoning uses a FEW specific observations to produce a GENERAL hypothesis?

Premise statements

The ____ method involves seeking answer by logical reasoning

Rational method

The ____ is an approach to acquiring knowledge that involves formulating specific questions and then systematically finding answers

Scientific method

What method is used by behavioral scientists to answer questions?

Scientific method

Why does the scientific method combines several different methods of acquiring knowledge?

To avoid pitfalls of any individual method used by itself

What are some examples of pseudoscience in hearing and speech?

What are some problems with the method of authority?

-It does not always provide accurate information (e.g., authorities can be biased) -Answers obtained from an expert could represent subjective, personal opinion rather than knowledge -Assume that expertise in 1 area can be generalized to other topics (e.g., a famous athlete advertising) -People often accept an expert's statement without question -Not all experts are experts

What are the STEPS of the research process?

1) Find a research idea: select a topic and search the literature to find an unanswered question 2) Form a hypothesis 3) Determine how you will define and measure your variables 4) Identify the participants (human) or subjects (nonhuman) for the study. Decide how they will be selected, and plan for their ethical treatment. 5) Select a research strategy 6) Select a research design 7) Conduct the study 8) Evaluate the data 9) Report the results 10) Refine or reformulate your research idea

What are the steps of the scientific method?

1) Observe behavioral or other phenomena 2) Form a tentative answer or explanation (a hypothesis) 3) Use your hypothesis to generate a testable prediction 4) Evaluate the prediction by making systematic, planned observations 5) Use the observations to support, refute, or refine the original hypothesis

What are some potential solutions to prevent science from not being public?

1) Pay to have your article available in an open access journal 2) Pre-prints (some journals don't allow this; e.g., ASHA) 3) PubMed open access (i.e., if you have an NIH grant, they will make your article available after an initial embargo period)

Authority *For many questions, this is the quickest and easiest way to obtain answers

The methods of tenacity, intuition, and authority are good for answering some questions if you need an answer QUICKLY and if there are NO serious consequences for accepting a wrong answer The next two methods of acquiring knowledge are designed to place more ___ on the information and answers they produce

Demands

The method of authority can sometimes be called the method of ____ because people accept on faith any information that is given Accepting another's view of the truth without verification

Qualitative research

What are the limitations of the rational method?

The rational method "assumes" the premise statements are true People are not very good at logical reasoning *Sometimes the argument does not logically support the conclusion

____ research examines variables that typically vary in quantity (size, magnitude, duration, or amount) The results, or data, obtained from these measurements are usually numerical scores that can be summarized, analyzed, and interpreted using standard statistical procedures
