“…Some ERPs, for example, are thought to be correlated with specific cognitive processes, such as differentiating different auditory stimuli from one another or understanding words. These ERPs commonly occur at around 300 or 400 ms after stimulus onset (e.g., Kutas & Hillyard, 1980, Sur & Sinha, 2009). The use of ERP measures with the race IRAP in the current study was entirely exploratory, and thus no specific predictions were made pertaining to the ERPs waveforms that might emerge.…”

“…The process of averaging allows the researcher to distinguish the brain's normal background activity from the activity produced by the stimuli presented in the experiment (Sur & Sinha, 2009). In effect, each EEG signal for a particular set of stimuli is collated and averaged to produce a single waveform for each site, and then these waveforms are averaged across 1 In deciding to employ EEG during exposure to an IRAP, we are not suggesting that neural activity reveals a causal variable in a behavior-analytic sense.…”

“…ERPs occurring later are called 'cognitive' or 'endogenous'. These ERPs are sensitive to alternations in subject's mental state reflecting meaning of the stimulus (Kuperberg, 2008;Sur & Sinha, 2009). They examine information processing and reflect the manner in which the subject evaluates the stimulus.…”

Event-related potentials (ERPs) are characterised as brain voltage fluctuations associated in time with some physical or mental occurrence and represent a non-invasive technique reflecting activity of complex neuronal networks responsible for new stimuli detection and discriminative behaviour of individuals. ERPs are measured using electroencephalography and their applications became widespread since 1960s of the last century. This review brings introduction into the ERPs technique and characteristics of the individual ERPs components (particularly wave P300, Contingent Negative Variation, Mismatch Negativity and Bereitschaftspotential). In addition, it summarizes changes of ERPs associated with neurologic and psychiatric diseases and finally, it mentions possible use of this approach for purposes of experimental psychology.

“…Its versatility enables investigators to ask pertinent research questions about the relative timing of neural events in a large variety of domains, including language, cognition, and the study of various psychiatric disorders 10 such as schizophrenia, bipolar affective disorder, depression, and alcohol dependence disorder, and it offers substantial advantages over alternative methods of neuroimaging, such as functional magnetic resonance imaging (fMRI). Some of these include its excellent temporal resolution, which elucidates brain activity down to the millisecond.…”

Within the field of cognitive neuroscience, functional magnetic resonance imaging (fMRI) is a popular method of visualizing brain function. This is in part because of its excellent spatial resolution, which allows researchers to identify brain areas associated with specific cognitive processes. However, in the quest to localize brain functions, it is relevant to note that many cognitive, sensory, and motor processes have temporal distinctions that are imperative to capture, an aspect that is left unfulfilled by fMRI's suboptimal temporal resolution. To better understand cognitive processes, it is thus advantageous to utilize event-related potential (ERP) recording as a method of gathering information about the brain. Some of its advantages include its fantastic temporal resolution, which gives researchers the ability to follow the activity of the brain down to the millisecond. It also directly indexes both excitatory and inhibitory post-synaptic potentials by which most brain computations are performed. This sits in contrast to fMRI, which captures an index of metabolic activity. Further, the non-invasive ERP method does not require a contrast condition: raw ERPs can be examined for just one experimental condition, a distinction from fMRI where control conditions must be subtracted from the experimental condition, leading to uncertainty in associating observations with experimental or contrast conditions. While it is limited by its poor spatial and subcortical activity resolution, ERP recordings' utility, relative cost-effectiveness, and associated advantages offer strong rationale for its use in cognitive neuroscience to track rapid temporal changes in neural activity. In an effort to foster increase in its use as a research imaging method, and to ensure proper and accurate data collection, the present article will outline -in the framework of a paradigm using semantic categorization to examine the effects of antipsychotics and schizotypy on the N400 -the procedure and key aspects associated with ERP data acquisition.
