A Model of Eye Movements and Visual Attention

This paper introduces the EMMA model of eye movements and visual attention. EMMA provides a formal model of the temporal and spatial aspects of eye movements as they arise from shifts in visual attention. To implement the model, EMMA is integrated into the ACT-R/PM cognitive architecture (Anderson & Lebiere, 1998) and requires minimal modification of existing ACT-R/PM models. This paper details the EMMA model, theory, and implementation and also demonstrates how the extended framework helps to capture important aspects of behavior in an equation-solving task.
