In AP Psychology, gustation is the sense of taste. Receptors on the tongue and in the mouth transduce chemicals into the basic tastes of sweet, sour, salty, bitter, umami, and oleogustus for processing in the brain (EK 1.6.D).
Gustation is just the technical word for taste. It's one of the two chemical senses (the other is olfaction, or smell), meaning it works by detecting actual chemical molecules from your food rather than light or sound waves.
Here's how it fits the bigger sensation picture. When you eat, taste receptors on your tongue, mouth, and throat pick up the chemicals in food and transduce them, which means they convert that chemical signal into neural messages the brain can read. Your brain sorts these into six basic tastes: sweet, sour, salty, bitter, umami (savory), and oleogustus (fatty). How sensitive you are to those tastes depends on how many taste receptors you have. People with a lot are supertasters, people with average amounts are medium tasters, and people with few are nontasters. So the same lemon can taste wildly sour to one person and only mildly sour to another, and that's not in their head, it's in their receptor count.
Gustation lives in Unit 1: Biological Bases of Behavior, under Topic 1.6 Sensation. It's part of learning objective 1.6.D, which asks you to explain how the structures and functions of the chemical sensory systems relate to behavior and mental processes. Taste is a perfect example of transduction, the core sensation idea from 1.6.A, where a physical stimulus (chemicals in food) becomes a neural message. It also shows the bigger Unit 1 theme that behavior and experience are built on biology. Why a food tastes the way it does to you comes down to receptors and brain processing, not just opinion.

Olfaction (Unit 1)
Taste and smell are partners, not rivals. Most of what you call 'flavor' is actually your nose doing the work, which is why food tastes bland when you have a cold. The CED groups them together as the chemical senses for exactly this reason.
Papillae and Umami (Unit 1)
Papillae are the little bumps on your tongue that house taste buds, and umami is one of the six tastes those buds detect. If you can name the structure and the taste qualities, you've basically got the gustation question locked.
Sensory Adaptation (Unit 1)
Gustation adapts like every other sense. The first bite of a salty snack tastes intensely salty, but by the tenth bite you barely notice it. That's diminished sensitivity to a constant stimulus, the same idea from 1.6.A that applies to vision and touch too.
Gustation shows up mostly on multiple-choice questions in two flavors. The first kind asks you to identify a basic taste from a description, like recognizing that a 'savory, mouth-filling' broth is umami or that the 'sharp, acidic' bite of a lemon is sour. The second kind tests how senses interact, such as the finding that high-pitched sounds can enhance perceived sweetness, which is an example of your sensory systems working together. No released FRQ has used the word gustation verbatim, but it's strong evidence material for any free-response prompt asking you to explain sensation, transduction, or how biology shapes experience. Your job is usually to match the term to the right structure or taste, or to explain how taste connects to the broader sensation process.
Gustation is taste (tongue and mouth) and olfaction is smell (nose). The catch is that what feels like taste is mostly smell, so they're easy to mix up. One clean difference for the exam: smell is the only sense that skips the thalamus, while taste does not get that special treatment.
Gustation is the sense of taste, one of the two chemical senses along with olfaction.
The six basic tastes you need to know are sweet, sour, salty, bitter, umami, and oleogustus (fatty).
Taste receptors transduce chemicals in food into neural messages the brain processes, the same transduction idea behind all sensation.
Your number of taste receptors makes you a supertaster, medium taster, or nontaster, which is why the same food tastes different to different people.
Flavor is mostly smell, so taste and olfaction work together, which is why food tastes flat when you're congested.
Gustation is the sense of taste. Receptors on your tongue and in your mouth detect chemicals in food and transduce them into neural signals, sorting them into six basic tastes (sweet, sour, salty, bitter, umami, oleogustus) under learning objective 1.6.D.
No. Taste (gustation) is just the six basic qualities your tongue detects, while flavor is the full experience, which is mostly created by smell (olfaction). That's why food tastes bland when your nose is stuffed up.
Gustation is taste, handled by receptors in the tongue and mouth, and olfaction is smell, handled by the nose. A useful exam fact: smell is the only sense not processed first in the thalamus, while taste is.
Six basic tastes: sweet, sour, salty, bitter, umami (savory), and oleogustus (fatty). Questions often describe a sensation, like a 'savory, mouth-filling' broth, and ask you to name the taste (umami).
It comes down to receptor count. People with many taste receptors are supertasters and find tastes intense, while nontasters have few and find the same food mild. This is one of the few CED concepts where individual biology directly changes the experience.
