Individual and ensemble perception are key processes for successful interaction with objects in our environment that focus on single objects or the extraction of summary information from groups of objects, respectively. The underlying mechanism(s) are still being investigated, including how the perception of individual versus ensembles is impacted by the number of target objects. While previous studies have used primarily simplistic stimuli, it is unknown how this translates to the real world. To address this gap, we conducted a computer-based experiment where participants had to remember and indicate via mouseclick either the position of a single object or the average position of all target objects within a naturalistic scene. We investigated differences in individual versus ensemble perception as they relate to scene encoding (initial scene presentation time: 50, 100, or 800 ms) and set size (3, 6, or 10 objects). Results indicated that scene encoding time had a similar effect on both, individual and ensemble locating accuracy, which increased with more encoding time. However, set size modulations revealed distinct effects on the two processes: For individual perception, locating accuracy was generally higher and improved for smaller set sizes. In contrast, for ensemble perception, smaller set sizes were associated with lower locating accuracy, particularly at shorter encoding times such as 50 ms. These findings suggest that individual and ensemble perception is influenced differently by the (amount of) task-relevant information. Ultimately, this points to a complementarity of these processes, in supporting real-world actions under different contexts.
