Stimuli, conditions and trial structures. A Examples of stimuli used in the main study. Top panel: tools presented at 45, 0, and 315 degrees. Bottom panel: tools presented at 135, 180, and 225 degrees. B Four study conditions resulting from the combination of three different action goals (indicated by goal cues) and two sets of stimulus orientations. C Trial structure and timing of the main experiment, using an event-related design. D Trial structure and timing of the visual tool use localizer task with a block design. E Trial structure and timing of the background study on structure-based (i.e., grasping to displace or move) vs. function-based pantomimed grasping of tools, utilizing a block design
