Document Summary

N empirical method: method used to gather info i. e. standardized tests or measurements with a high level of objectivity. N replication: replication of results to make sure initial observations not fluke, ensures generalizability. N control: manipulate something to see its effects. N confounding variable: unwanted variable that may affect the outcome of the study. N hypothesis: prediction, formed as a statement that can be rejected. N independent variable: researcher manipulates it i. e. time of day. N dependent variable: response or behaviour that is measured i. e. test score. N since it is difficult for neuropsychology to use the scientific method because it would impossible and unethical in may situations, it uses: converging operations. S method of research where a common conclusion is reached by examining a number of studies that approach the question from a variety of diff. perspectives. S if there is a consensus in results, can be confident about the generalizability www. notesolution. com.
