  1. Chapter 2.1:What is Research? Mr. McCormick Psychology

  2. Do-Now:(In Journal/With a Partner) In Journal: • For each of the following research topics, choose a research methodthat you think would be best used to gather the necessary information: • The shopping trends of 15-19 year-olds • The causes of eating disorders • The success of high school freshmen (throughout high school) in an urban setting • Playground behaviors of fourth-graders • The TV viewing habits of children, teens, young adults, middle-aged adults, and senior citizens • The effect of caffeine on test performance

  3. Experiments • Experiments begin with a hypothesis • (e.g. “Caffeine improves test performance”)

  4. Experiments • Experimenters must employ variables: • Independent Variable: • Manipulated/changed by experimenter to observe its effects (e.g. Coffee/Redbull) • Dependent Variable: • The effects/changes that occur in relation to the independent variable (e.g. improved test performance)

  5. Experiments • Experimenters divide participants into two groups: • Experimental Group: • Independent variable is applied (e.g. Coffee is given to participants) • Control Group: • Treated the same way as experimental group, but independent variable is not applied (e.g. No coffee is given to participants)

  6. Experiments Why would experimenters wish to employ an experimental and a control group?

  7. Review • A psychologist wishes to test the effects of cell phone use on driving. To do so, he creates an experiment in which 80 participants partake in a driving test. 40 participants must talk on their phone while driving, while 40 participants may not. Identify the following: • Hypothesis • Independent Variable • Dependent Variable • Experimental Group • Control Group

  8. Homework • Complete “Guided Reading Activity: 2-1” worksheet • Questions 1-10 • Use Textbook Chapter 2.1 (pgs. 35-41)
