An Example How can we decide who is right about the effects of  something like sex in the media?  Some say it increases the likelihood children will have sex  earlier Some conclude that it does not. Is there a more scientific way to determine the answer?  Social psychologists believe there is.

Social Psychology:  An Empirical Science  A fundamental principle of social psychology is  that social influence can be studied  scientifically. The results of some of the experiments you  encounter may seem obvious Social psychology concerns everyday topics  you may already be familiar with

Social Psychology:  An Empirical Science  Three types of answers to these  questions:  observational method correlational method experimental method. Probably familiar from some  other psych class, but we’ll  go over it in terms of social  psych.

Social Psychology:  An Empirical Science  Each is a powerful tool in some ways and a  weak tool in others.  Involves choosing the right method, maximizing  its strengths, and minimizing its weaknesses.

Going back to that example Could it be something else? Personality  Disposition Seeking out sexy  media Having sex earlier Third-variable problem: when a third  variable causes a relationship between  two other variables

Social Psychology: An Empirical Science  “I knew Obama would win!” Once we know the winner of a political election,  the outcome seems inevitable and easily  predictable The same is true of findings in psychology  experiments. It seems like we could have easily predicted  the outcomes—once we know them.

Social Psychology: An Empirical Science  The trick is to predict what will happen in an  experiment before you know how it turned out.  Hindsight Bias Tendency for people to exaggerate how much they  could have predicted an outcome after knowing that it  occurred.

    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.
