Verified step by step guidance

1. Step 1: Understand the concept of primary taste sensations, which are the basic categories of taste that the human tongue can detect according to psychological and physiological research.
2. Step 2: Identify the commonly accepted primary taste sensations, which typically include Sweet, Sour, Bitter, Salty, and Umami. These are considered fundamental because they correspond to specific types of taste receptor cells on the tongue.
3. Step 3: Recognize that 'Spicy' is not classified as a primary taste sensation. Instead, the sensation of spiciness is related to pain receptors and temperature sensors, not taste buds.
4. Step 4: Compare the options given (Spicy, Sour, Bitter, Umami) against the list of primary tastes. Sour, Bitter, and Umami are all primary tastes, while Spicy is not.
5. Step 5: Conclude that the correct answer is 'Spicy' because it does not fit the definition of a primary taste sensation in psychological theories of taste perception.
