Document Summary

Psyc 110 - lecture 2 - intro to psychometrics. No known limits to the amount of information that can be stored. Estimated to outprocess our best man-made supercomputers by 100x. Evolution has shaped our brains into taking short cuts. One shortcut is the tendency to connect even unrelated things. Use the theory to make a prediction: prediction. Design an experiment to test the prediction: experiment. Most direct and conclusive way to test a hypothesis. Independent variable dependent variable result. Independent variable is manipulated (ex. happy pill) Dependent variable stays the same across the study (ex. mood questionnaire) Mnemonic: the dependent variable depends on the independent variable . Same subject will be given multiple manipulations/conditions across time. Usually multiple subjects, but can be a single subject. Much less conclusive than experimental design, but still useful. No manipulation of variables, rather it is the observation of already existing variables.
