Copy machine… You are copying papers and a lady asks to use thecopy machine do you let her? What percent of people will say yes?- 60%-80%Subject’s Age? Mood? Subject Status?-Gender?Compliance (Men saying yes to women: chivalry) Time of day?Document Imp.? Subject’s # of copies?These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- A lot of factors MAY influence compliance- We must distinguish between dispositional matters and situational matters.Age= Personality Time of Day=Situational Document Imp.=Situational Subject Status= Sit.Mood= Sit. Gender=Person. # of copies=Sit. - How can we eliminate the ?? - Focus one 1 quality. - To determine what influences compliance keep all variables the same except one. In this case the argument quality is strong rather than no argument at all.- No argument = The Control of the experiment while the strong argument= the experimental variable.- 95% of people said yes to her strong argument. Coin toss Ladies Argument Quality Compliance-Coin toss decides whether the lady gives a strong argument or not. -We can assume the only difference in the groups is that they received different arguments.Random Assignment- Assigning people to different groups in an experiment in such a way that everyone has an equal chance of being in each condition/groupIf the lady observed the subject and decided they looked agreeable then she would decide on her argument meaning agreeableness influences argument quality. Possibilities: 1. -Using random assignment eliminates a third variable to influence argument quality and compliance. 2.-Is it possible to conclude compliance caused her argument quality?-NO – can’t have an effect before the cause3.Only one possibility is logical: argument quality influences compliance.Not concluding that Agreeableness DOES NOT influence compliance.We can conclude that our independent variable – x – influenced the dependent variable – y IIndependent variable- the variable the is manipulated (Argument Quality)Dependent variable- the variable the is measured (compliance)Third Condition is a weak argument “May I use the copy machine because I need to make some copies” 95%
