This study investigated the distribution of visual attention along a handheld tool depending on functional tool practice and its position in peripersonal or extrapersonal space. We created a tool with two functional parts placed at the tool’s middle and end. Participants held the tool over a display such that functional parts were aligned with stimuli for a(More)
Despite attentional prioritization for grasping space near the hands, tool-use appears to transfer attentional bias to the tool’s end/functional part. The contributions of haptic and visual inputs to attentional distribution along a tool were investigated as a function of tool-use in near (Experiment 1) and far (Experiment 2) space. Visual attention was(More)
Researchers acknowledge the interplay between action and attention, but typically consider action as a response to successful attentional selection or the correlation of performance on separate action and attention tasks. We investigated how concurrent action with spatial monitoring affects the distribution of attention across the visual field. We embedded(More)
