Abstract: Humans are specialized in eye-hand coordination through a complex visuospatial system. When a tool is observed, the motor areas of the brain are activated and, when grasped, it is sensed as a part of the body. One approach to understanding the underlying mechanisms behind this process regards the analysis of visual attention. Vision influences the spatial interaction with tools and plays a crucial role in the perception of an object’s affordances. In this study, we employ eye-tracking technology to investigate whether Lower Palaeolithic stone tool morphology influences visual attention during visual exploration and manipulation. Our results suggest that the handaxe morphology has a moderate influence on the visual scanning of the tool. In contrast, visual exploration of the chopper is only influenced by the weight of the tool. The different visual behaviours exerted by these two technologies suggest divergences in the visuospatial process underlying the interaction with these tools.
