Illustration of the task. After the participant has picked a bottle from a previous platform (cf. bottle already in the hand), they will transport it toward the next platform (a,b), onto which they will release it (c). Please note that a semi-transparent bottle has been added on the target platform (a,b) to help the participant fitting their bottle with the target zone and that the bottle turned red (c) when within the target zone.
