PSYCH 100B Lecture 1: Week 1 Lecture 1
Document Summary
Needs no evidence, we don"t stop to question them. Ex: belief that soup makes a cold better. Based on authority, somebody you trust told you so, or "everybody" knows. Maintain belief, despite counter evidence, hard to sway ppl. Ex: eat soup again, even if you got sick again after eating soup. Evidence based (empirical aka evidence that is gathered that are objective and unbiased) Change our theory of the cause and e ect. "will to doubt," constantly questioning the evidence, always trying to prove yourself wrong. Start with hypothesis (idea that something is related to something else) (cid:8775) Ex: many ppl believe that tv watching a ects children"s behavior, watching violent tv programs --> aggressive behavior. Take survey and ask parents how much violent tv does the child watch per week and how would they rate their children"s violent behavior. Predictor variable = tv hrs per week (cid:8775) Use this variable to nd something out about the criterion variable.
