Gesture & Memory

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, 2018).

Retrieval & Memory Modification

Memory is a dynamic system which continuously adapts and changes to accommodate new information. When information is retrieved from memory it becomes reactivated in such a way that memories become plastic and can be disrupted or enhanced by the present context (e.g., Hupbach, Gomez, & Nadel, 2009). Our research investigates the conditions under which memory is made most adaptable such as exploring the how different types of retrieval and contextualization of information (Overoye, James, & Storm, 2021) can potentiate new learning.
