Can affective overload be anticipated and prevented? This presentation introduces the Emotion Thresholds Methodology (ETM) for assessing affective tolerance—defined as the point at which a stimulus exceeds an individual's emotional capacity to sustain positive valence or regulated arousal. The model is based on three distinct thresholds: the Unpleasantness Threshold (UT), where valence turns negative; the Arousal Threshold (AT), where stimulation surpasses optimal activation; and the Compromised Pleasure Threshold (CPT), where both dimensions fail to maintain a pleasurable experience. These thresholds do not measure discrete emotions but serve as indirect indicators of affective compromise, identifying when a stimulus becomes emotionally taxing, aversive, or disengaging. Originally developed in sensory science, the model holds strong potential for broader application. In clinical contexts, thresholds can support the monitoring of affective responses in individuals with eating disorders, sensory sensitivities, or emotional dysregulation. In educational and occupational settings, they may inform emotionally sustainable environments. In public health and policy, they provide novel criteria to support psychoeducational strategies that align with emotional well-being. These thresholds are not intended to measure affective tolerance per se, but to enable a better assessment of the personal attitude that shapes one's response to emotional impulses. Although initial studies demonstrate sensitivity in detecting valence shifts (UT, CPT), operationalizing arousal thresholds (AT) remains methodologically challenging—particularly with simplified affective scales or low-arousal stimuli. By identifying the points at which emotional responses become concerning, the model offers a promising tool for shaping environments, guiding adaptive interventions, and promoting emotional agency. The methodology bridges psychophysics and affective science in ways that advance applied psychological research and reinforce its societal relevance.
