Sensory overload can result from the overstimulation of any of the senses. Hearing : loud noise, or sound from multiple sources, such as several people talking at once. Sight : crowded or cluttered spaces, bright lights, strobing lights, or environments with much movement such as crowds or frequent scene changes on television.
Hypokalemic sensory overstimulation is a neurological disorder characterized by a subjective experience of sensory overload and a relative resistance to lidocaine local anesthesia. The sensory overload is treatable with oral potassium gluconate .
Sensory cravings, [13] including, for example, fidgeting, impulsiveness, and/or seeking or making loud, disturbing noises; and sensorimotor-based problems, including slow and uncoordinated movements or poor handwriting. Sensory discrimination problems, which might manifest themselves in behaviors such as things constantly dropped. [citation needed]
People diagnosed with sensory processing disorder are also known to potentially exhibit more stimming behaviors. [4] Stimming has been interpreted as a protective response to overstimulation, in which people calm themselves by blocking less predictable environmental stimuli, to which they have a heightened sensitivity.
Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin.
AVE effects on the EEG are found primarily over the sensory-motor strip, frontally, and in the parietal lobe (somatosensory) regions and slightly less within the prefrontal cortex. [ 3 ] It is within these areas where motor activation, attention , executive function , and somatosensory (body) awareness is primarily mediated.
Writing in 1985, C. E. M. Hansel discovered weaknesses in the design and possibilities of sensory leakage in the ganzfeld experiments reported by Carl Sargent and other parapsychologists. Hansel concluded the ganzfeld studies had not been independently replicated and that "ESP is no nearer to being established than it was a hundred years ago."
In psychology, Jeanne Siaud-Facchin uses the term by defining it as an "exacerbation des sens" [2]: 37 that characterizes gifted individuals: for them, the sensory information reaches the brain much faster than the average, and the information is processed in a significantly shorter time.
