“…Replicating classic neural findings, they include parallel and converging pathways for the analysis of shape and motion cues. Their plausibility as models of real neural mechanisms is supported by their abilities to recognize actions in biological motion displays 93 , detect goal-directed hand actions 94 , and even detect animacy and simplified social interactions between two moving dots 95 . The fact that the model combines these abilities fits with a proposed similarity between the computational mechanisms of action and causality perception, namely the analysis of sequences of spatiotemporal relationships between interacting stimulus elements 96,97 .…”

“…Surprisingly, however, only very little is known about how coordinated group behavior is processed in the brain. Indeed, existing models of biological motion perception have largely focused on processing the movements of individuals (Giese and Poggio 2003) or dyads (Hovaidi-Ardestani et al 2018). These models have proposed two pathways for processing biological motion.…”

The human brain has dedicated mechanisms for processing other people’s movements. Previous research has revealed how these mechanisms contribute to perceiving the movements of individuals but has left open how we perceive groups of people moving together. Across three experiments, we test whether movement perception depends on the spatiotemporal relationships among the movements of multiple agents. In Experiment 1, we combine EEG frequency tagging with apparent human motion and show that posture and movement perception can be dissociated at harmonically related frequencies of stimulus presentation. We then show that movement but not posture processing is enhanced when observing multiple agents move in synchrony. Movement processing was strongest for fluently moving synchronous groups (Experiment 2) and was perturbed by inversion (Experiment 3). Our findings suggest that processing group movement relies on binding body postures into movements and individual movements into groups. Enhanced perceptual processing of movement synchrony may form the basis for higher order social phenomena such as group alignment and its social consequences.

“…However, while the adaptive functions of group behavior are well-documented, little is known about how the brain represents the movements of groups (Riddell & Lappe, 2018;Sweeny et al, 2013). Indeed, existing models of biological motion perception have largely focused on processing the movements of individuals (Giese & Poggio, 2003) or pairs (Hovaidi-Ardestani et al, 2018). These models have distinguished two pathways for processing biological movement.…”

Humans and other animals have evolved to act in groups, but how does the brain distinguish multiple people moving in group from multiple people moving independently? Across three experiments, we test whether biological motion perception depends on the spatiotemporal relationships among people moving together. In Experiment 1, we apply EEG frequency tagging to apparent biological motion and show that fluently ordered sequences of body postures drive brain activity at three hierarchical levels of biological motion processing: image, body sequence, and movement. We then show that movement-, but not body- or image-related brain responses are enhanced when observing four agents moving in synchrony. Neural entrainment was strongest for fluently moving synchronous groups (Experiment 2), displayed in upright orientation (Experiment 3). Our findings show that the brain preferentially entrains to the collective movement of human agents, deploying perceptual organization principles of synchrony and common fate for the purpose of social perception.
