sansning

Sansning is a term used in Swedish and Danish to denote sense perception—the experience of sensing environmental stimuli through the body's sensory systems. It covers the major modalities of vision, hearing, touch, taste, and smell, as well as internal senses such as proprioception. In everyday language, sansning can refer to the act of perceiving as well as to the faculties by which perception occurs.

Physiologically, sansning begins with specialized receptors that transduce physical or chemical stimuli into neural signals. These signals travel via sensory nerves to the central nervous system, where initial processing occurs in brain regions such as the thalamus and sensory cortices. Perception emerges when the brain interprets and integrates these signals with memory, context, and expectation, producing a conscious experience rather than mere detection.

Cognitive and developmental aspects: Sansning is influenced by attention, prior knowledge, and context, leading to phenomena such as perceptual constancies and illusions. It develops from infancy and can be altered by aging, disease, or injury. Pathologies can affect parts of the perceptual pathway, producing deficits like agnosias or sensory losses, while other conditions can distort interpretation of sensory input.

Usage and related terms: In scientific and philosophical contexts, sansning is often equated with perception, though some distinctions between sensation and perception are drawn depending on language and discipline. The term remains common in Scandinavian languages for everyday talk about sensing as well as formal discussions of sensory processing.
