Humans organise their social worlds into social and nonsocial events. Social event segmentation refers to the ability to parse the environmental content into social and nonsocial events or units. Here, we investigated the role that perceptual information from visual and auditory modalities, in isolation and in conjunction, played in social event segmentation. Participants viewed a video clip depicting an interaction between two actors and marked the boundaries of social and nonsocial events. Depending on the condition, the clip at first contained only auditory or only visual information. Then, the clip was shown containing both auditory and visual information. Higher overall group consensus and response consistency in parsing the clip was found for social segmentation and when both auditory and visual information was available. Presenting the clip in the visual domain only benefitted group agreement in social segmentation while the inclusion of auditory information (under the audiovisual condition) also improved response consistency in nonsocial segmentation. Thus, social segmentation utilises information from the visual modality, with the auditory cues contributing under ambiguous or uncertain conditions and during segmentation of nonsocial content.
人类将他们的社交世界组织成社交和非社交事件。社交事件分割是指将环境内容解析为社交和非社交事件或单元的能力。在这里，我们研究了来自视觉和听觉模态的感知信息，无论是单独还是结合，在社交事件分割中的作用。参与者观看了一段描述两个演员之间互动的视频剪辑，并标记了社交和非社交事件的边界。根据条件的不同，剪辑最初只包含听觉或视觉信息。然后，显示包含听觉和视觉信息的剪辑。在社会分割和听觉和视觉信息都可用的情况下，发现整体组共识和解析剪辑的响应一致性更高。仅在视觉域中呈现剪辑有助于提高社会分割的组一致性，而听觉信息的包含（在视听条件下）也提高了非社交分割的响应一致性。因此，社会分割利用来自视觉模态的信息，而听觉线索在模糊或不确定条件下以及在非社交内容的分割中提供帮助。
