Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.
