Question: If I want to build up a sentence like; 

"If you don't have a gift idea and want to pay much." 

Does this "not" make both verbs (have - want) negative? It seems like it works but I still have doubts about it. Or what is the correct form of this grammar ?

Answer: 
**Sensory Memory**. Smell is called [olfactory memory](https://en.wikipedia.org/wiki/Olfactory_memory), touch is called [haptic memory](https://en.wikipedia.org/wiki/Haptic_memory), hearing is called [echoic memory](https://en.wikipedia.org/wiki/Echoic_memory), and image is called [iconic memory](https://en.wikipedia.org/wiki/Iconic_memory). Oddly, there doesn't seem to be a term for taste memory. Another term of interest is [eidetic memory](https://en.wikipedia.org/wiki/Eidetic_memory). Eidetic memory (unlike the link's description) can be applied to all the senses, and it refers to the strong, sometimes overwhelming and debilitating, welling up of memories caused by some recent stimulus. I have a good friend with this condition.
There is the term [**involuntary memory**](https://en.wikipedia.org/wiki/Involuntary_memory) that is the *memory that occurs when cues encountered in everyday life evoke recollections of the past without conscious effort.*

This is most notably described by Marcel Proust in his novel [*Remembrance of Things Past*](https://en.wikipedia.org/wiki/In_Search_of_Lost_Time). Notably, he describes an incident where the taste of a madeleine cake dipped in tea brings forth memories of his youth.

However, this specific scenario (though not necessarily the entire range of *involuntary memory*) occurs when a taste (in this case) brings back other memories, vs something bringing back the memory of a taste/smell.
