The Research Process: Theories, hypothesis, and research questions (cont.) 4/9/2009 Testing a Hypothesis: An Example - Researcher A - Social cognitive theory: children learn behavior by watching models behave - Hypothesis: watching TV violence will increase kids’ aggressive behavior - Huge endowments, big donors to do research (600 children) - How much violent TV viewed - How much aggression on playground - Conclusion: TV violence increases aggression Cannot control the shows that the children watch, so the conclusion should be changed to “TV violence is related to aggression” - Researcher B - Catharsis theory: watching others behave allows “purging” of pent-up feelings - Hypothesis: watching TV violence will reduce kids’ aggressive behavior - Doesn’t have as much money (60 children) - Watch one of four clips (0, 5, 10, 20) - Number of hits on toys - Conclusion: TV violence decreases aggression (for these people, these lab conditions, and etc) because it’s not a representative sample Types of Hypotheses and Research Questions -

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
