NEWS: Canadiens won! Ladies win appeal to sue Dr. Phil Pervy Stunt Dead birds litter Quebec farm Science An objective approach to knowledge - a challenge because the scientiFc method grew out of our better effort to understand nature around us (worked very well for physics, chem, bio but in social psych sometimes the tools for the scientiFc method don’t Ft the phenomena we are trying to understand in social psychology (ex. what is the meaning of life? abstract constructs and things that are more at the spiritual level, the scientiFc tools do not help us answer those questions and we will be limited in the number of questions we can ask and sometimes we have to take human nature and morph it into the lab so we can study it. Lab Study Video: - experimenter showing face of card to two people who have to guess what shape is on the back and when they get it wrong they get shocked. the boy continuously gets it wrong and gets shocked and when the girl guesses he just pretends it is right so that she does not get shots. - Dependent variable: the effects of ____ on ______ * (this blank is the dependent variable); in this case the dependent variable is ESP abilities; ESP is a construct that is brought into the lab and we need a way of measuring the variable and “operationally deFne it”; ESP ability is considered as ________ (the number of correct responses you give to these cards) in the lab. ESP is the global construct that we need to operationally deFne as above. - independent variable: the effects of ____* (this is the independent variable); in this situation it was “negative reinforcement” Science - Questions may be biased - want to be able to use techniques or approaches or procedures that will be systematic and reproducible. When I conduct an experiment and write a paper, in the procedure section I want to describe what I did in detail so that if you wanted to copy the study you could replicate the study successfully with my Fndings. The more that people get the same Fndings, the more conFdence we have in the Fndings. If people Fnd different things in the same studies than we have a problem; therefore we need systematic procedures. - what is not objective often is what the question are that we ask. Science does not tell us what are important questions to ask. We ask questions based on theories and conceptual models which can be biased by a number of in±uences. .. - our tools allow us to be systematic and producible but the questions may be biased - process systematic and reproducible - we must come up with criteria to help us come up with the material we will be studying Jan 11th; 215
