Abstract
Visual foraging tasks, where participants collect items by touching or clicking on them, have become
popular for investigating visual search. They probe selective attention in multi-target contexts through
naturalistic goal-directed actions, unlike the button presses used in many other paradigms. Despite
their potential, such tasks had not been used to examine the interplay of attention and goal-directed
actions until now, even though this topic has been extensively studied with other paradigms and has
significant implications for understanding human visual behavior in the real world. In this study, we
applied the visual foraging paradigm to address this gap. We found that attentional prioritization of
one part in a two-part compound object is accompanied by a motor bias in the collecting action (stylus
tap) toward the prioritized part. This bias combines with motor precision demands, such as aiming
for stable contact points. Our findings show that action planning not only modulates the attentional
landscape at large but also that attentional asymmetries (e.g., prioritizing one object part) feed back
into the motor system, combining with motoric factors to refine goal-directed actions.
