Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Sensory substitution and sensory augmentation are the same thing. | Sensory substitution and sensory augmentation are two different concepts in neuroscience. Sensory substitution involves using one sense to replace or supplement another sense, while sensory augmentation involves enhancing an existing sense beyond its natural capabilities. |
| Sensory substitution is only used for people with disabilities. | While sensory substitution can be helpful for individuals with disabilities, it has potential applications for anyone looking to enhance their perception of the world around them. For example, some researchers have explored using auditory cues to help drivers navigate traffic more safely by alerting them to nearby vehicles they may not see visually. |
| Sensory augmentation always requires technology or external devices. | While many examples of sensory augmentation involve technology or external devices (such as hearing aids), there are also ways to augment senses through training and practice alone (such as improving visual acuity through eye exercises). |
| The brain cannot adapt to new forms of sensory input from sensory substitution or augmentation techniques. | The brain is highly adaptable and can learn to interpret new forms of information from alternative senses over time with practice and training, allowing individuals who use these techniques to develop a richer understanding of their environment than they would otherwise have access to through traditional senses alone. |
