Document Summary

The research process: psychological research aims to use scientific methods to investigate human behaviours (cid:1006). Predi(cid:272)tio(cid:374)s: develop a question, where do research questions come from, previous research/literature, disbelief of other theories, observations from data, case studies, everyday observations, make predictions, hypotheses. If a condition is met, then these consequences should follow: help us move towards research designs, test the predictions, need a plan to carry out research. Intelligence tests: cognitive tests, physiological measures, activity in the body that is recorded, ex, electroencephalography (eeg, genes, sleep tracker. Descriptive research: naturalistic observation, observes animal/person in fairly natural setting. Investigates the relationship among psychological variables: correlation does not reflect causation, variables are related but do not cause each other, example: similarity and happiness, variable a: ratings of couple similarity, variable b: happiness measures. Investigates which variables cause behaviours, thoughts, emotions: manipulate variable a, see change in variable b, control for other factors.
