Document Summary

Into adulthood: behavior in childhood predicts adult outcomes. Parents can accurately report their children"s early years. Learning objectives: describe the scientific method as a means for testing hypotheses and answering questions, compare correlational and experimental methods. Discuss special ethical issues that should be considered (i. e. , informed consent), and what precautions are taken to ensure that children are protected. We can"t always design a suitable experiment. Some researchers are solely interested in describing patterns/paths: a laboratory experiment permits a researcher to establish a causal association by manipulating the independent variable and assessing the effect on the dependent variable in a controlled setting. Observer bias = an observer"s tendency to be influenced by knowledge about the research design or hypothesis. Intervention = a program provided to improve a situation or relieve psychological illness or distress: in a natural experiment, the investigator measures the effect of a naturally occurring change.
