From: Spatial analogies pervade complex relational reasoning: Evidence from spontaneous gestures
Examples of the different gesture types, taken from two participants’ explanations. Factor reference gestures (a, e) represent the factors as locations in space (yellow circles). Factor change gestures (b, f) represent increases and decreases as movements (straight yellow arrows). Causal relation gestures (c, g) represent causation as movement (curved yellow arrows). Whole system gestures (d, h) represent the behavior of the system as a whole and often involve multiple movement phases (multiple yellow arrows)
