PS102 Lecture Notes - Lecture 2: Demand Characteristics, Logic Level
Document Summary
Deductive reasoning: reasoning from broad basic applied to specific situations. Biases: distorted beliefs based on a person"s subjective sense on reality. Inductive reasoning: proceeding from small specific situations to more general truths. Hypothetico-deductive reasoning: scientists begin with an educated guess about how the world works and then sets observation/hypothesis. Independent variables: condition or event that is thought to be a factor in changing another factor. Dependant variable: condition that you expect to change as a result of variations in the independent variable. Operationalize: develop a working definition of variable that allows you to test it. Descriptive research method: allows researchers to develop a relationship between variables of interest without specifying a casual relationship. Double blind effect- neither the participants nor the experimenters know who is receiving a particular treatment. Particularly useful for preventing bias due to demand characteristics or the placebo effect.
