A 64-channel BioSemi ActiveTwo electroencephalography (EEG) system is currently being installed in the PLAN Lab. EEG is the recording of electrical activity along the scalp produced by neuronal firing. Derivatives EEG techniques include evoked related potentials (ERPs), which involves averaging the EEG activity time-locked to the presentation of a stimulus. Discrete ERP components reflect aspects of automatic cognitive processing, and are therefore critical to neurocognitive investigation. The primary advantages of ERP research include high temporal resolution (on the order of milliseconds), the use of non-invasive procedures, and the capacity for continuous processing measurement. EEG methodologies have been pivotal in mapping the neural correlates of cognitive bias as well as experimentally-induced changes in pathological biases.
