  1. Research Methods in Psychology

  2. Historical Psychology Research • Modern sophistication was not always present • Psychology’s roots exist in Philosophy and the natural sciences which sprung from it • Rene Descartes’ disagreement with dualism (the concept that mind and body are separate and distinct)

  3. Historical Psychology Research, cont. • Wilhelm Wundt founded the first psychology laboratory in 1879 • He tried to test his theories and statements by collecting ‘scientific’ data • Although unreliable and cumbersome, his method of introspection led to the use of the scientific method in psychology • Introspection: a method of self-observation in which participants report their thoughts & feelings in carefully controlled situations

  4. Psychologists, like researchers in all other sciences, use the scientific methodto test their ideas empirically How Do Modern Psychologists Develop New Knowledge?

  5. How Do Modern Psychologists Develop New Knowledge? • What is the scientific method? • A step-by-step process for empirical investigation of a hypothesis under conditions designed to control biases and subjective judgments • Psychologists obtain empirical results from experiments using the scientific method

  6. The Scientific Method Gathering Objective Data Developing a Hypothesis Perform Controlled Test(s) Analyze the Results Publishing, criticizing, & replicating the Results

  7. The Steps of the Scientific Method Gathering objective data Data: Information gathered by researcher and used to test a hypothesis Developing a hypothesis Perform Controlled Test(s) Analyze the Results Publish, criticize & replicate the results

  8. The Steps of the Scientific Method Gathering objective data Hypothesis:A statement predicting the outcome of a scientific study Developing a hypothesis Perform Controlled Test(s) Analyze the Results Publish, criticize & replicate the results

  9. The Steps of the Scientific Method Gathering objective data Independent variable:The variable manipulated by the experimenter Developing a hypothesis Perform Controlled Test(s) Analyze the Results Publish, criticize & replicate the results

  10. The Steps of the Scientific Method Gathering objective data Developing a hypothesis Perform Controlled Test(s) Based on statistical analyses of results, the hypothesis is accepted or rejected Analyze the Results Publish, criticize & replicate the results

  11. The Steps of the Scientific Method Gathering objective data Developing a hypothesis Perform Controlled Test(s) Analyze the Results Researchers must find out whether their work can withstand the scrutiny of the scientific community Publish, criticize & replicate the results

  12. How Do Psychologists Develop New Knowledge? • What does empirical mean? • Relying on or derived from observation or experiment • Psychologists use empirical investigation • An approach to research that relies on sensory experience and observation as research data
