Hyposensitivity, also known as Sensory under-responsitivity, refers to abnormally decreased sensitivity to sensory input. Hyposensitivity is especially common for autistic people and is more often seen in children than adults and adolescents due to masking. Those experiencing this have a harder time stimulating their senses than normally.
Empirical models based on nonlinear regression are usually preferred over the use of some transformation of the data that linearizes the stimulus-response relationship. [ 11 ] One example of a logit model for the probability of a response to the real input (stimulus) x {\displaystyle x} , ( x ∈ R {\displaystyle x\in \mathbb {R} } ) is
Sensory modulation refers to a complex central nervous system process [1] [45] by which neural messages that convey information about the intensity, frequency, duration, complexity, and novelty of sensory stimuli are adjusted. [46] SMD consists of three subtypes: Sensory over-responsivity. Sensory under-responsivity; Sensory craving/seeking.
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.
Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response. [1] Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated.
Emotional responsivity is connected to broader psychology concepts about emotions. People exhibit emotions in response to outside stimuli. People exhibit emotions in response to outside stimuli. Positive affective stimuli trigger feelings of pleasure such as happiness; negative affective stimuli trigger feelings of displeasure such as disgust ...
The BAS, FFFS, and BIS are dependent systems, and current research attempts to define under what task situations and to what degree they interact. A rewarding stimulus may activate all three systems to some extent such that high scores on a BAS-related behavioral trait, for example, may include high BAS, low FFFS, and low BIS activations. [3]
Not many studies have been done on sensory overload, but one example of a sensory overload study was reported by Lipowski (1975) [35] as part of his research review on the topic that discussed the work done by Japanese researchers at Tohoku University. The Tohoku researchers exposed their subjects to intense visual and auditory stimuli ...
