“…In general, the preschool children showed the expected P1-N250 response to the standard stimuli with frontocentral voltage distributions (Albrecht et al, 2000;Ceponiene et al, 1998;Ponton et al, 2000;Sharma et al, 1997;Sussman et al, 2008). Additionally, a negative frontocentral peak was observed at 350 ms latency.…”

“…The difference started already at 107 ms and lasted until 215 ms. This time window will develop into N1-P2 responses later in life (Albrecht et al, 2000;Ponton et al, 2000). It remains unclear what this early group difference specifically signifies besides differences in auditory cortex functions.…”

“…However, maturational changes in EEG occur rapidly already before school age (Albrecht et al, 2000;Choudhury et al, 2011;Ponton et al, 2000). The present study examined electrophysiological indices of auditory discrimination in children at preschool with and without risk factors for dyslexia.…”

“…With inter-stimulus intervals (ISIs) shorter than one second, the waveform of children younger than 10 years is characterized by P1 and N250 responses, emerging approximately 100 ms and 250 ms after stimulus onset (Sharma et al, 1997;Sussman et al, 2008). After 9 years of age, the N1-P2 complex starts to emerge and gradually grows in amplitude to adult values while the P1-N250 complex reduces in amplitude (Albrecht et al, 2000;Ceponiene et al, 2002;Ponton et al, 2000;Tonnquist, 1996, Wunderlich et al, 2006. The P1-N250 complex shows a fronto-central voltage distribution and has sources close to the auditory cortex (Parviainen et al, 2011;Ponton et al, 2002).…”

Event-related potentials to tones show differences between children with multiple risk factors for dyslexia and control children before the onset of formal reading instruction Hämäläinen, Jarmo; Lohvansuu, Kaisa; Ervast, Leena; Leppänen, Paavo H.T.Hämäläinen, J., Lohvansuu, K., Ervast, L., & Leppänen, P. (2015). Event-related potentials to tones show differences between children with multiple risk factors for dyslexia and control children before the onset of formal reading instruction. AbstractMultiple risk factors can affect the development of specific reading problems or dyslexia. In addition to the most prevalent and studied risk factor, phonological processing, also auditory discrimination problems have been found in children and adults with reading difficulties. The present study examined 37 children between the ages of 5 and 6, 11 of which had multiple risk factors for developing reading problems. The children participated in a passive oddball EEG experiment with sinusoidal sounds with changes in sound frequency, duration, or intensity. The responses to the standard stimuli showed a negative voltage shift in children at risk for reading problems compared to control children at 107-215 ms in frontocentral areas corresponding to P1 offset and N250 onset. Source analyses showed that the difference originated from the left and right auditory cortices. Additionally, the children at risk for reading problems had a larger late discriminative negativity (LDN) response in amplitude for sound frequency change than the control children. The amplitudes at the P1-N250 time window showed correlations to letter knowledge and phonological identification whereas the amplitudes at the LDN time window correlated with verbal short-term memory and rapid naming. These results support the view that problems in basic auditory processing abilities precede the onset of reading instruction and can act as one of the risk factors for dyslexia.

“…However, risetime dependent modulations of ERP components have not been studied in adults with dyslexia. Children's auditory ERP responses differ considerably from those measured in adulthood (Albrecht et al, 2000;Bishop et al, 2007;Tonnquist-Uhlen et al, 2003;Ponton et al, 2000;Pang and Taylor, 2000). Nevertheless, a little is known about ERP correlates of rise time processing in 8-10 year old children with dyslexia.…”
