External threats are a major source of our experience of negatively valanced emotion. As a threat becomes closer and more real, our specific behavior patterns and our experiences of negative affect change in response to the perceived imminence of threat. Recognizing this, the National Institute of Mental Health's Research Domain Criteria (RDoC) Negative Valence system is largely based around different levels of threat imminence. This perspective describes the correspondence between the RDoC Negative Valence System and a particular neurobiological/neuroecological model of reactions to threat, the Predatory Imminence Continuum (PIC) Theory. Using the COVID-19 pandemic as an illustration, we describe both adaptive and maladaptive behavior patterns from this perspective to illustrate how behavior in response to a crisis may get shaped. We end with suggestions on how further consideration of the PIC suggests potential modifications of the negative valence systems RDoC.
外部威胁是我们体验负性情绪的主要来源。随着威胁变得越来越接近和真实,我们的特定行为模式以及我们对负面影响的体验会随着所感知到的威胁紧迫性而发生变化。认识到这一点,美国国立精神卫生研究所的研究领域标准(RDoC)负性情绪系统主要基于不同程度的威胁紧迫性。这一观点描述了RDoC负性情绪系统与一种特定的对威胁反应的神经生物学/神经生态学模型——捕食紧迫性连续体(PIC)理论之间的对应关系。以新冠疫情为例,我们从这个角度描述了适应性和适应不良的行为模式,以说明应对危机时的行为是如何形成的。最后,我们就进一步考虑PIC如何提示对RDoC负性情绪系统进行潜在修正提出了建议。
