Document Summary
Investigating how the brain produces behavior in humans. The scientific method: has at its roots in the principles of objectivity and replication or confirmation of results. Empirical method = level of objectivity observation . Replication: when neuropsychologists try to replicate their results to prove their findings were not a fluke. Control: the ability to manipulate something to determine the effects and cut out extremes and confounding variables that may cause a researcher to make false conclusions. Refers to having an appropriate comparison sample so that deviations from this sample can be observed. Hypothesis prediction that may be formed as a statement that can be rejected. Independent variable: variables that researcher manipulates to determine how the behavior is affected. Dependent variable: response or behavior that the experimenter measures. Converging operations: allows conclusions to be made based on different ways that a hypothesis is tested.
