Picking the Right Piece: How Action Intentions Shape Visual Search and Action Planning in Foraging

Resumen

Everyday behavior, like grocery shopping, often includes search for multiple objects of one kind. Such “visual foraging” tasks have recently received more attention in vision science. However, although object search is usually performed for object interaction, only few studies have been conducted with real objects. When interacting with real-world objects, factors such as the type of interaction and its precision requirements are likely to affect object selection. When high precision is required, actions are performed more carefully (e.g., with lower speed and a longer deceleration phase). In addition, action contexts—such as the type or endpoint of movements—affect adaptive movement planning and action parameters, including grasp point selection and movement speed. To investigate such influences in interactive real-world visual foraging, we asked participants to pick and place LEGO bricks defined by color and varied the precision requirements with different placing instructions. Movement analysis revealed that participants preferred nearby objects but also prioritized those beneficial to the task, such as larger objects when instructed to create a pile. This demonstrates that participants planned reach movements by balancing immediate movement costs with future precision demands. Our results emphasize that task and action context, such as placing requirements or the environmental layout, need to be considered for understanding visual selection in real-world situations.
