Sensory adaptation is a neurological process that reduces sensitivity to constant stimuli, allowing focus on changes in the environment. It affects all senses and can vary among individuals, especially those with autism spectrum disorders (ASD), who may experience heightened sensitivities. This adaptation is crucial for cognitive efficiency but can also lead to overlooking important stimuli.

Sensory adaptation is a neurological process that decreases our sensitivity to constant stimuli, allowing us to focus on dynamic changes in our environment
Cognitive Efficiency
Sensory adaptation allows us to efficiently process sensory information by filtering out irrelevant or non-changing aspects of our environment
Individual Perceptual Set
The degree of sensory adaptation can vary based on the strength of the stimulus and an individual's prior experiences and expectations
While beneficial for navigating our sensory environment, sensory adaptation can also cause us to overlook critical information
Sensory adaptation can occur in all senses, such as touch, smell, taste, sight, and hearing
Autism Spectrum Disorders (ASD)
Individuals with ASD may experience atypical sensory sensitivities, including diminished sensory adaptation, which can result in challenges when processing repetitive or intense sensory information
Variations in Sensory Adaptation
Sensory adaptation can manifest differently among individuals, depending on their perceptual experiences and sensitivities
Habituation is a behavioral response to repeated stimuli, while sensory adaptation is an automatic physiological process that reduces the neural response to a constant stimulus
Ticking Clock
A person may habituate to the sound of a ticking clock, choosing to ignore it after determining it poses no danger or need for attention
Visual Adaptation
Under certain conditions, visual adaptation can cause parts of an image to disappear from awareness
While habituation involves a decrease in behavioral response and is a form of learning, sensory adaptation is an innate physiological response

Role of sensory adaptation in attention focus
Allows ignoring constant stimuli to concentrate on changing environmental aspects needing response.
01
Sensory adaptation occurrence location
Happens at sensory receptors and neural pathways with reduced response to ongoing stimulus over time.
02
Factors influencing degree of sensory adaptation
Stimulus strength and perceptual set, latter shaped by experiences and expectations affecting sensory interpretation.
