Sensory substitution
Sensory Substitution
Sensory substitution refers to the use of one sensory modality to supply environmental information normally gathered by another sense. It is a non-invasive technique used to compensate for the loss of one sense by feeding its information through another channel.
Pronunciation
/sɛnsəri sʌbstɪˈtjuːʃən/
Etymology
The term "sensory substitution" is derived from the Latin words "sensus" meaning "sense" and "substitutio" meaning "substitution".
Definition
Sensory substitution systems are devices that aim to compensate for the loss of a particular sense by providing the same information through another sensory channel. For example, visual information can be presented audibly or tactilely, and auditory information can be presented visually.
Related Terms
- Sensory Augmentation: This refers to the enhancement of the sensory perception system by providing additional input not normally received.
- Neuroplasticity: This is the ability of the brain to change and adapt in response to new experiences, including the use of sensory substitution devices.
- Assistive Technology: This is a broad term that includes any device, system, or design used to improve the functional capabilities of individuals with disabilities, such as sensory substitution devices.
Applications
Sensory substitution has been used in various fields such as medicine, psychology, and technology. In medicine, it is used to help individuals with sensory impairments, such as blindness or deafness. In psychology, it is used to study the plasticity of the brain and the flexibility of perception. In technology, it is used to develop assistive devices for individuals with sensory impairments.
Research
Research in sensory substitution aims to understand the underlying mechanisms of sensory perception and the brain's ability to adapt to new sensory inputs. This research has implications for the development of assistive technologies and the treatment of sensory impairments.
