Scientific method Hypothesis Prediction Experimental design Variables Independent Dependant Groups Experimental Control Test Analysis scientific theory if it cant be tested it is not scientific theory Schachter s Theory Anxiety reduction is one of the things that causes humans to seek out the company of others Testing the theory if you manipulate the level of anxiety making some people very anxious and some not at all What you should see is that the people experiencing high levels of anxiety should want to be with other people more than the others with lower anxiety The experiment People placed in a lab told if they were to be shocked if they made a mistake some people were told theyd receive a small shock others told it would be a very large shock This is meant to manipulate and control the level of anxiety Subject is allowed to wait in a room alone or a room with people Making a prediction what you expect to observe in the experiment typically about subjects behavior what the subject will do If the theory is right and we have an experiment The prediction is that the proportion of people who want to wait with others will be higher in the high anxiety group then in the low anxiety group The indepentant variable Cause variable you directly control and manipulate In this experiment the level of anxiety Dependent variable Effect a measure of what the subject does in the experiment measures the magnitude of the effect In this experiment it is what the subject does how many people choose to be alone and how many people choose to be in the room of people 60 of high anxiety chose to wait with others 32 of low anxiety chose to wait with others The prediction is about the dependant variable it is predicting what the dependant variable is going to be Analysis The prediction was fulfilled There is evidence to support the claim that anxiety Scientific Research Introduction Experimental research Scientific method Experimental design Extraneous variables Limitations Correlational research Correlation Examples Limitations Casual conclusions Third variable prob Experimental research the strongest most powerful research we can do
