Chemical Senses: These are the sensory systems responsible for detecting chemical stimuli in the environment. The core chemical senses discussed are smell and taste.

Smell (Olfaction): The scientific or formal term for the sense of smell is olfaction. This involves the detection of airborne chemical molecules.

Significance: The discussion around these senses is highlighted as being of "very high" importance, indicating that these concepts are foundational or require careful attention.

Selective Attention: Understanding these chemical senses is presented as a "test of selective attention," suggesting that listeners or learners need to focus and discern important details within this topic.
