Previous findings revealed that social ostracism reduces people's sense of agency and body ownership, and vicarious ostracism reduces agency. Given theoretical claims that other's and own behavior may be cognitively represented similarly, we compared the impact of first-hand and vicarious social ostracism on agency and ownership, using both explicit and implicit measures. Participants were separated into target group and observer group, to experience first-hand or vicarious ostracism or inclusion. We used a virtual Cyberball game to induce social ostracism or inclusion; and virtual hand illusion, where participants could freely control a virtual hand by moving their real hands, for agency and ownership measurements. Findings show that, both first-hand and vicarious ostracism reduced agency and ownership in both explicit and implicit measures. While the implicit measures were affected by first-hand and vicarious experience equally, the explicit measures showed a stronger reduction of agency and ownership for first-hand than for vicarious experience.
先前的研究结果表明，社会排斥会降低人们的能动感和身体所有权感，而替代性排斥会降低能动感。鉴于理论上认为他人和自己的行为在认知上可能有相似的表征，我们使用显性和隐性测量方法，比较了亲身经历的和替代性的社会排斥对能动感和所有权感的影响。参与者被分为目标组和观察组，以体验亲身经历的或替代性的排斥或接纳。我们使用虚拟的Cyberball游戏来引发社会排斥或接纳；并使用虚拟手错觉，即参与者可以通过移动自己的真实手部来自由控制一只虚拟手，以测量能动感和所有权感。研究结果表明，无论是亲身经历的还是替代性的排斥，在显性和隐性测量中都会降低能动感和所有权感。虽然隐性测量受到亲身经历和替代性经历的影响相同，但显性测量显示，与替代性经历相比，亲身经历对能动感和所有权感的降低作用更强。
