  3. Purpose and Goals Class  Provide a general toolbox for behavioral science * Emphasis on experiment design  * Emphasis on social/personality research Science Concepts Nature of science Logic of experiments Experiment design Statistics: Basic Stats T-Tests Factorial ANOVA Planned Contrast Regression Moderated Multiple Regression Techniques: Question design Writing tips

  4. FACTORIAL DESIGN Self Esteem, External Support, and Height JudgmentsHarber, Yeung, & Iacovelli, Emotion, (in press).

  5. Subjects Have High or Low Esteem, and….

  6. High or Low External Resources

  7. Factorial Design Factor 1: ??? Esteem: Low vs. High Factor 2: ??? External resource: Present vs. Absent How many questions does this design address? • Main effect Esteem • Main effect External Resource • Interaction of Esteem X Resource

  8. Factorial Design

  14. Loyalty in Organizations • Measures • Observations • Relationships • Hypotheses • Theory

  15. Develop Theory Cognitive Dissonance: drive to align experience with beliefs. Explain Human Nature “WHY” Test Hypotheses Severe Initiation  Liking of fraternity "HOW" Reveal Relationships Severe Initiation  Liking of fraternity Frat boys: mad  glad??? Observe Behav. Liking of fraternity Initiation rites “WHAT”

  16. How are the Elements of Science Organized? Relationships Experiments Observations Theory

  17. Hierarchy Model of Science Theory Hypothesis Experiment Measures/ Observations

  18. Where Does the Fly Belong on the Hierarchy?

  19. Theory Observations/Measures Hypotheses Experiments Mandela (Recursive) Model of Science

  20. Cross Chatter of Science Theory Observations/ Measures Hypotheses Experiments Experiments Observations/Measures Hypotheses

  21. THEORY--DEFINED A theory is a set of interrelated constructs (concepts), definitions, and propositions that present a systematic view of phenomenon by specifying relations among variables, with the purpose of explaining and predicting phenomena (Kerlinger & Lee, p. 11).

  22. Jigsaw Puzzle Model of Science Data = Pieces Correlations = Joining of pieces to form larger pieces  Hypotheses = Ways of organizing pieces: “All same- colored pieces go together.” Theory = The entire puzzle, or enough of it to predict where missing pieces go and connect AND NOW WE WILL TEST A HYPOTHESIS …..

  23. THEORY AND SEEING HMAS Sydney Sunk in Indian Ocean 1941; Found (in part) Via Cog. Psychology 2008 http://www.npr.org/2011/09/27/140816037/how-psychology-solved-a-wwii-shipwreck-mystery Bartlett's War of the Ghosts schema research, ca. 1930 Create "deviation maps" from Bartlett's original subjects Apply same method to German sailors' stories

  24. Behaviors Behaviors * People will help a fellow shopper pick up spilled groceries after they, themselves, break a stranger’s camera. * People who form ambivalent romantic relationships tend to be unsure about the existence of a supreme being. * Paying children to do a task that they already like doing will make them like the task less. * Young children are more likely to freely explore if they have non-depressed mothers. * People become more loyal believers in a cult if the cult’s own predictions don’t come true. * People who tend to avoid close relationships also tend to be more mentally rigid. Theories As Organizers of Behavior Cognitive Dissonance Attachment Theory

  26. Hypotheses Unburdened by Data Each [social psychology] deception study leads to a breakdown in [societal] trust. Sissela Bok Our most important protections in a new world will be our old values. David Gergen, Editor at Large, U.S. News and World Report January 3, 2000
