Aberrant salience, defined as the inappropriate attribution of significance to neutral stimuli, is increasingly recognized as a critical mechanism in the onset of psychotic disorders. In young individuals at ultra-high risk (UHR) for psychosis, abnormal salience processing may serve as a precursor to full-blown psychotic symptoms, contributing to distorted perceptions and the onset of psychotic ideation. This review examines current literature on aberrant salience among UHR youth, exploring its neurobiological, psychological, and behavioral dimensions. Through a comprehensive analysis of studies involving neuroimaging, cognitive assessments, and symptomatology, we assess the consistency of findings across diverse methodologies. Additionally, we evaluate factors contributing to aberrant salience, including neurochemical imbalances, dysregulation in dopamine pathways, and environmental stressors, which may jointly increase psychosis vulnerability. Identifying aberrant salience as a measurable trait in UHR populations could facilitate earlier identification and targeted interventions. Implications for clinical practice are discussed, highlighting the need for specialized therapeutic approaches that address cognitive and emotional dysregulation in salience attribution. Recent research underscores the importance of aberrant salience in early psychosis research and advocates for further studies on intervention strategies to mitigate progression to psychosis among UHR individuals.
异常显著性,定义为对中性刺激赋予不适当的重要性,越来越被认为是精神障碍发病的关键机制。在处于精神病超高风险(UHR)的年轻人中,异常显著性处理可能是全面精神病症状的先兆,导致感知扭曲和精神病性观念的出现。本综述考察了当前关于UHR青年异常显著性的文献,探讨其神经生物学、心理学和行为学维度。通过对涉及神经影像学、认知评估和症状学的研究进行全面分析,我们评估了不同方法研究结果的一致性。此外,我们评估了导致异常显著性的因素,包括神经化学失衡、多巴胺通路失调和环境应激源,这些因素可能共同增加精神病易感性。将异常显著性确定为UHR人群中可测量的特征有助于早期识别和针对性干预。讨论了对临床实践的影响,强调了需要专门的治疗方法来解决显著性归因中的认知和情绪失调问题。最近的研究强调了异常显著性在早期精神病研究中的重要性,并主张进一步研究干预策略,以减轻UHR个体发展为精神病的进程。
