“…Environmental stimuli including emotionally loaded stimuli, also referred to as affective stimuli, may capture and divert attention regardless of their relevance to ongoing tasks (Dolcos & McCarthy, 2006), affecting children's cognitive control processes (Tottenham et al, 2011;Schell & Crone, 2013) and eliciting a range of subjective and autonomic responses (McManis et al, 2001;Shapiro, Sgan Cohen, Parush, & Melmed, 2009;Sharp et al, 2006).

They found that among the children with developmental delays the calming effect was more pronounced compared to typically developing children.…”
