“…In many cases, gestures carry information that is not carried in speech. Considerable research has shown that information carried solely by gesture can facilitate learning, thinking and understanding in both children and adults in a broad range of tasks including conservation (e.g., Church, Ayman-Nolley, & Mahootian, 2004; Ping & Goldin-Meadow, 2008), word learning (McGregor, Rohlfing, Bean, & Marschner, 2009), problem solving (Beilock & Goldin-Meadow, 2010; Singer & Goldin-Meadow, 2005; Tversky & Kessell, 2014), sentence memory (Thompson, Driscoll, & Markson, 1998), asymmetry (Valenzeno, Alibali, & Klatzky, 2003), math (e.g., Alibali & DiRusso, 1999; Cook, Duffy, & Fenn, 2013; Cook & Goldin-Meadow, 2006; Goldin-Meadow et al, 1999; Segal, Tversky, & Black, 2014), math analogies (Richland & McDonough, 2010), cyclical and simultaneous time (Jamalian & Tversky, 2012), story understanding (Beattie & Shovelton, 1999), and more.…”
