“…From birth, infants resonate with the emotions of others, reacting to others' distress signals with personal distress (Dondi, Simeon & Caltran, 1999;Geangu, Benga, Stahl & Striano, 2010). As infancy ends, emotional contagion begins to be replaced with other-focused responses (Zahn-Waxler, Radke-Yarrow, Wagner & Chapman, 1992;Svetlova, Nichols & Brownell, 2010). For example, infants as young as 12 months spontaneously help others to retrieve an accidentally displaced object (Liszkowski, Carpenter, Striano & Tomasello, 2006;Warneken &Tomasello, 2006, and 2-year-olds will often attempt to repair harm they have caused (Barrett, Zahn-Waxler & Cole, 1993;Kochanska, Gross, Lin & Nichols, 2002).…”
