Other Factors Influencing Perception
Personal characteristics. Personal characteristics, such as past experience (learning) and motivation, may also affect the way stimuli are perceived.
Learning (a musician quickly learns the pattern of tones that make a melody and detects a discordant note)
Motivation (while an individual may not initially have a taste for espresso coffee, if the person's group of acquaintances perceives it as an “in” beverage, he or she may then start drinking espresso)
