it can be any of these imaginative processes:

• Kinesthetic: imagine the feel and weight of binoculars and how they feel when you put them to your eyes.
• Auditory: hear the sound of an electronic microscope zooming in on a subject.
• Visual: specifically imagine the color of a camera’s metal and plastic parts, or how the light bounces off its surfaces.
• Emotional: imagine how it feels to see a loved one again after a long time apart.
• Conceptual: think about the concept of something being visual, perhaps by imagining the word itself appearing on a screen.

[ed. from a Youtube comment he adds cryptically "But a tip would be to perhaps think in terms of genre as a replacement."]

[ed. 2: Ah he means replace "conceptual" with genre]

• Olfactory: imagine the smell of rain after you’ve heard distant thunder and seen a lightning clap.
• Gustatory: imagine the taste of that same rain.
• Spatial: think about the size of your vision in terms of how far you can see or how big objects are relative to one another.

To remember all of these options, think of the words “KAVE COGS.” Then, whenever you read, move through each step strategically in order to make sure you’re using multisensory visualization.
