Award winning Emotiv EPOC+ research grade 14 Channel Mobile EEG designed for practical contextualized research and advanced BCI applications. Previous work has demonstrated that a commercial gaming electroencephalography (EEG) system, Emotiv EPOC, can be adjusted to provide valid auditory event-related potentials (ERPs) in adults that are comparable to ERPs recorded by a research-grade EEG system, Neuroscan. The aim of the current study was to determine if the same was true for children. An adapted Emotiv EPOC system and Neuroscan system were used to make simultaneous EEG recordings in nineteen 6- to 12-year-old children under “passive” and “active” listening conditions. In the passive condition, children were instructed to watch a silent DVD and ignore 566 standard (1,000 Hz) and 100 deviant (1,200 Hz) tones. In the active condition, they listened to the same stimuli, and were asked to count the number of ‘high’ (i.e., deviant) tones. Intraclass correlations (ICCs) indicated that the ERP morphology recorded with the two systems was very similar for the P1, N1, P2, N2, and P3 ERP peaks ( r =.82 to.95) in both passive and active conditions, and less so, though still strong, for mismatch negativity ERP component (MMN; r =.67 to.74). There were few differences between peak amplitude and latency estimates for the two systems. An adapted EPOC EEG system can be used to index children’s late auditory ERP peaks (i.e., P1, N1, P2, N2, P3) and their MMN ERP component. Introduction An auditory event-related potential (ERP) is the average pattern of electrical activity generated by neurons in response to a particular auditory event. Auditory ERPs can be measured without a listener’s overt attention. Such “passive” auditory ERPs are a useful means of investigating the role of auditory processing in people who find it difficult to pay attention to stimuli, to make decisions about stimuli, or plan overt responses to stimuli. Thus, passive auditory ERPs have proved useful for investigating auditory processing in attention deficit hyperactivity disorder (ADHD; ), schizophrenia (); autism (); developmental dyslexia (); and specific language impairment (). ![]() A limitation of passive auditory ERPs is that they are typically measured using research-grade equipment housed in a laboratory. Such settings can be intimidating for many people, particularly children and adults with cognitive disorders. Fortunately, recent research has shown that a commercial “gaming” electroencephalography (EEG) system, called “EPOC” by Emotiv (), can be adapted to produce valid ERPs. Examined auditory ERPs in “passive” (standard and deviant tones are ignored) and “active” (deviant tones are counted) listening conditions in adults, using an adapted EPOC system and a research-grade Neuroscan system. They found high reliability for the “late auditory ERP” peaks (i.e., P1, N1, P2, N2, and P3) but not for the “mismatch negativity” component (MMN; see ). The EPOC system has also been successfully used to measure the auditory P3 response (; ) and the visual P3 response (; ).

Considered together, the outcomes of these seminal studies suggest that the EPOC system can be adapted to record valid auditory P1, N1, P2, N2, and P3 ERP peaks in adults. To our knowledge, no study has yet tested if an adapted EPOC system can produce valid auditory ERPs in children. This cannot be inferred from previous validation studies done with adults because children have (1) different ERPs to adults due to cortical and cognitive immaturity (;;; ); (2) “noisier” ERPs than adults (); and (3) more difficultly keeping still during long test sessions than adults, so their EEG (and ERP) responses may be contaminated to a greater degree by electrical noise generated by movement. The aim of the current study was to test the validity of children’s passive and active auditory ERPs measured via an adapted EPOC system. In line with an analogous adult study (i.e., ) we predicted that the adapted EPOC system would produce valid ERPs for the highly reliable late auditory ERP peaks (P1, N1, P2, P2, P3) but invalid ERPs for the less reliable MMN component. Participants Participants were twenty-one children (11 females, 10 males) aged between 6 and 12 years (M = 9.23, SD = 1.80). Parents or guardians of the children provided written informed consent for their child’s participation (see for information-consent form), and children were reimbursed $15 for their time. Participants were required to have normal hearing and vision, and no history of epilepsy. One child was excluded from the study due to a reported hearing loss; another child was excluded because the EPOC event-markers failed to record; and a third was excluded due to a condition coding error. Therefore, the final sample included 18 children.
