重复性消极思维（RNT）是一种内化精神病理的跨诊断危险因素，理论模型表明，RNT可能通过干扰心理生理习惯化来维持症状。因此，本研究考察了RNT与学习期间和学习期间的习惯之间的联系。社区成员（N=86）完成了一项习惯化任务，包括平均间隔7天暴露于声学探针多达5次。用肌电惊级法测定眨眼惊反应。在每个阶段的习惯化任务之前和之后评估自我报告的焦虑。多水平生长曲线模型表明，RNT与较高的惊吓反应“下限”（即渐近线）相关，这一点在随后的会议中得到了证明。结果表明，RNT可能会破坏惊吓习惯，并与理论模型一致，理论模型提出RNT维持生理激活以支持避免负面情绪对比或感知到的未来威胁。
Repetitive negative thinking (RNT) is a transdiagnostic risk factor for internalizing psychopathology, and theoretical models suggest that RNT may maintain symptoms by interfering with psychophysiological habituation. The present study therefore examined associations between RNT and habituation within and between study sessions. Community members (N=86) completed a habituation task involving exposure to acoustic probes at up to five sessions spaced 7 days apart on average. Eyeblink startle response was measured using the electromyography startle magnitude. Self-reported anxiety was assessed before and after the habituation task at each session. Multilevel growth curve modeling indicated that RNT was associated with a higher “floor” (i.e., asymptote) of startle responding as evidenced by reduced within-session startle habituation at later sessions. Results suggest that RNT may disrupt startle habituation and are consistent with theoretical models proposing that RNT sustains physiological activation to support avoidance of negative emotional contrasts or perceived future threats.
