Sensingaffects

Sensingaffects is a term used in cognitive and affective science to describe the bidirectional relationship between sensory processing and affective states. It refers to processes by which mood, arousal, and other emotional qualities alter perceptual thresholds, salience, and interpretation, as well as the ways sensory input can evoke, regulate, or modulate emotional experiences.

Mechanisms involve neural circuits across the sensory and limbic systems, including the amygdala, insula, anterior cingulate cortex, and prefrontal areas, as well as neuromodulatory systems involving dopamine and norepinephrine. Interoceptive pathways link bodily signals to affect, while multisensory integration combines information from different senses within an affective context. The effects can be rapid and automatic or more controlled, depending on attention and prior expectations.

Examples include anxiety increasing perceptual vigilance for threat-related cues, taste and flavor being intensified or dulled by mood, and pain perception shaped by emotional state. Sensory experiences can also serve as a regulatory mechanism, where calming stimuli reduce arousal and negative affect, or emotionally charged stimuli intensify sensory processing.

Methodology and challenges include psychophysical experiments, affect labeling, physiological measures, neuroimaging, and ecological momentary assessment. Difficulties involve disentangling causality (whether mood alters perception or vice versa), accounting for individual differences, and controlling context effects.

History and applications: the concept has roots in affective neuroscience and perception research and intersects with interoception and emotion–cognition studies. Applications span clinical assessment, user-interface design, marketing, and therapies such as pain management and exposure-based treatments. Related areas include interoception, multisensory integration, and mood-congruent processing.
