Speech paired with gesture has been shown to
enhance memory for spoken information when compared to speech alone (Beattie & Shovelton, 1999; Goldin-Meadow, 2014; Koumoutsakis, et al., 2016 ; Macoun & Sweller, 2016, Valenzeno, Alibali, & Klatzky, 2003). Further,
when gestures provide information that goes beyond what is presented in speech,
listeners readily insert information from gesture into their recollection of
that speech (Cassel, McNeill, & McCullough, 1998; Kelly, et al., 1999). Our research asserts that such
profound effects of gesture on memory are the result of the formation of an
integrated representation of gesture and speech in memory – one which is uniquely
co-activated during retrieval whereby retrieval of speech leads the
co-activation of gestural information (Overoye & Storm, 2018). Additionally, our work examines the boundaries for when gesture and
speech are integrated and explore potential mechanisms by which gestures become
co-activated during retrieval of speech (Overoye & Storm, in prep).
Both producing and observing gestures has been shown to influence how people think and remember (e.g., Goldin-Meadow, 2014). In some cases, gesture enhances our ability to solve problems and remember (Beilock & Goldin-Meadow, 2010; Carlson et. al., 2014; Congdon et. al., 2017; Kang & Tversky, 2016) while in others it can potentially lead us astray (Broaders & Goldin-Meadow, 2010; Gurney, Pine, & Wiseman, 2013). Our research explores whether people are aware of the impact of gesture on their own thought and memory by examining how gestures influence judgements of learning, truth, and confidence.
