Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth. Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory hyperesthesia".
The inability to focus on relevant stimuli and filter out unnecessary and excessive sensory stimuli displayed in schizophrenics is due to physiological sensory gating issues, and the paired click P50 test can be used to determine if an individual has abnormalities in sensory gating and is therefore prone to sensory overload. [17]
Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social, and emotional stimuli". [2]
Sensitivity to stimuli: low threshold with passive response. Individuals who become distracted and uncomfortable when exposed to sensation but do not actively limit or avoid exposure to the sensation. [86] Sensation avoiding: low threshold and active response.

[1] When reflecting human emotion and behavior, it is commonly defined as the tendency to react to stimuli with negative affective states (especially anger) and temper outbursts, which can be aggressive.
Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.
A small amount of definitive research has led to the belief that intensity, sensitivity and overexcitability are primary characteristics of the highly gifted. The association between OE and giftedness appears to be borne out in the research. [6] It appears that at the least OE is a marker of potential for giftedness/creativity.
Other symptoms include high responsiveness to stimuli and constant scanning of the environment. [2] In hypervigilance, there is a perpetual scanning of the environment to search for sights, sounds, people, behaviors, smells, or anything else that is reminiscent of activity, threat or trauma. The individual is placed on high alert in order to be ...
