Document Summary
Used when the primary goal of research is to describe how children behave in their usual environments. Present identical situations to a number of children and record their behavior. Because every method has limitations, researchers often use a combination of techniques. Eeg/erps electrical activity of the brain fmri amount of oxygen in the brain fnirs amount of oxygen in blood (not going to get info) Erps are measures of changes in electrical activity that correspond to the presentation and processing of a stimulus. Result is a series of positive and negative deflections in the ongoing eeg time locked to a stimulus. Reliable marker of processing when participant can"t provide behavioral response. The degree to which independent measurements of a given behavior are consistent. The degree to which a test or experiment measures what it is intended to measure. Researchers have a vital responsibility to anticipate potential risks that the children in their studies may encounter.
