Explain the role of each sensory system in human behavior.
1. Sight
Sight allows humans to see their physical environment. This sense helps us to make judgements and navigate our environments more safely. People who are unable to see must rely on other senses to do those things.
2. Sound
Sound allows humans to process sounds and to interpret sounds into meaningful messages. This helps humans to be aware of things in their environments that they cannot see.
3. Smell
Smell allows humans to collect olfactory signals from their environments and translate them into smells. This sense helps people to sense danger and plays a role in human attraction. It is also closely relate to taste and is tied to memory and emotion.
