“…In adults, neural attenuation for bimodal synchrony is thought to reflect more efficient processing and has been documented in both early sensory and later attentional responses (Belse et al, 2004;Pilling, 2009;van Wassenhove, Grant, & Poepple, 2005), whereas attenuation has only been observed in later going attentional responses in infants (Hyde et al, 2011, Grossmann et al, 2006Reynolds et al, 2014;Vogel et al, 2012). Inconsistencies in the functional brain response between different experimental contexts in infants should not be taken as a limitation of the work, as most current views of multimodal processing and intersensory perception in adults conclude that context has a large effect on how, when, and where the brain is engaged (e.g., van Atteveldt et al, 2014;Matusz, Retsa, & Murray, 2016;Murray, Lewkowicz, Amedi, & Wallace, 2016). However, the fact that neural attenuation for bimodal synchrony has been documented exclusively in later attentional processing in infants but often appears during earlier sensory processing in adults may reflect a genuine developmental difference between infants and adults in efficiency and time course.…”
