Binding accounts propose that action planning involves temporarily binding codes of the action's unique features, such as its location and duration. Such binding becomes evident when another action (B) is initiated while maintaining the Action Plan A. Action B is usually impaired if it partially overlaps with the planned Action A (as opposed to full or no feature overlap). In Experiment 1, in which participants bimanually operated two keys, we replicated these partial overlap costs. In Experiment 2, two participants sat side by side, each handling one key. We tested whether Action B would be affected by duration overlap with the planned Action A of another person similarly as by duration overlap with a planned Action A of the participant's other hand. Here, we found no partial overlap costs. However, in Experiment 3, proposing a common reward yielded partial overlap costs. This suggests that in joint action planning, another person's action plan can impact own actions through feature binding, but only with sufficient incentives to corepresent the other's actions (i.e., when goal achievement depends on both participants' performance). This furthers the understanding of how we represent other people's yet-to-be-executed action plans alongside our own. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
