Mass univariate analysis of event-related brain potentials/fields II: Simulation studies.
Mass univariate analysis is a relatively new approach for the study of ERPs/ERFs. It consists of many statistical tests and one of several powerful corrections for multiple comparisons. Multiple comparison corrections differ in their power and permissiveness. Moreover, some methods are not guaranteed to work or may be overly sensitive to uninteresting deviations from the null hypothesis. Here w...
متن کاملMass univariate analysis of event-related brain potentials/fields I: a critical tutorial review.
Event-related potentials (ERPs) and magnetic fields (ERFs) are typically analyzed via ANOVAs on mean activity in a priori windows. Advances in computing power and statistics have produced an alternative, mass univariate analyses consisting of thousands of statistical tests and powerful corrections for multiple comparisons. Such analyses are most useful when one has little a priori knowledge of ...
متن کاملCluster-based computational methods for mass univariate analyses of event-related brain potentials/fields: A simulation study
BACKGROUND In recent years, analyses of event related potentials/fields have moved from the selection of a few components and peaks to a mass-univariate approach in which the whole data space is analyzed. Such extensive testing increases the number of false positives and correction for multiple comparisons is needed. METHOD Here we review all cluster-based correction for multiple comparison m...
متن کاملEvent-related brain dynamics.
Event-related potentials (ERPs) provide evidence of a direct link between cognitive events and brain electrical activity in a wide range of cognitive paradigms. It has generally been held that an ERP is the result of a set of discrete stimulus-evoked brain events. A recent study, however, provides new evidence to suggest that some ERP components might be generated by stimulus-induced changes in...
متن کاملEvent-related brain
The perception of complex auditory events such as speech and music depends upon a listener’s ability to extract temporal patterns from the ongoing acoustic input. Auditory pattern perception is influenced by stimulus-related factors such as the rate of presentation and frequency separation among elements composing the pattern,1-3 and more subjective factors such as the listener’s knowledge and ...
