why are you here? purpose of this part of the course - introduction to experimentalmethods in psychology • what you should be able to do by the end of the course basic experimental method and design basic statistics as they pertain to experimentation application of the above to other situations introduction to scientific writing and APA style
What is Psychology? • Psych = comes from the Greek word Psyche, meaning mind • -ology = the study of Thus, psychology is… The study of the mind & mental processes
How do we study mental processes? The Scientific Method • Theory • Hypothesis • Observation & Research Characteristics of Scientific Method: • Repeatable • Unbiased • Falsifiable
Goals of Science • Description • Prediction • Explanation
How do we measure mental processes? • Find an observable behavior that will indicate what’s going on in the mind • Example: Reaction Time • There is a way to observe and understand nearly all mental processes—we just have to find a way to do so via observable behavior
Components of the Experiment • Hypothesis • Participants • Independent & Dependent Variables • Collect & Analyze Data • Reach conclusions, revise theory and/or hypotheses, report to colleagues and others
Example Beer!
Theory: People do stupid things when they’re drinking
Participants • UConn male and female freshman intro to psychology students
Variables Independent Variable (IV) • Kind of Drinks (3 each) • Control = non-alcoholic (Coke) • Experimental condition = Beer • Manipulate between participants Dependent Variable (DV) • # of times each participant slurs, trips, etc.
Collect & Analyze Data Count # of times each participant trips IV Beer Coke DV # Times Trip 5.67 3.11
Reach conclusions • # of times trip: Ssalcohol > Ss non-alcohol • Results support Ho and general theory • Report results in journal publication, presentation, etc.
Experimental design • Variables: • independent: manipulated by the experimenter • dependent: measured by the experimenter • Reaction time study: • IV: the way in which the signal is passed on • 3 levels: left, right, alternate hand • DV: reaction time
