Associations are formed: Sight, sound, smell, taste, touch, feelings are triggered

 shape of the glass 

yesterday the sight of the clear beverage drinking glass triggered a message to me 'drink soda over ice"

so I drank a dr pepper soda pop over ice (first time in many months) however i did not use the clear beverage glass I have and saw due to past experience knowing that the glass condensates leaving water puddles on the table
