Final answer:
Physiological or psychological deficiencies that motivate behavior are called needs, which lead to drive states that motivate us to satisfy those needs and form habits.
Step-by-step explanation:
Physiological or psychological deficiencies that arouse behavior are called needs. According to the drive theory of motivation, these needs create psychological drive states that motivate an individual's behavior. For example, when you are hungry, the physiological need for food initiates a drive state (hunger), compelling you to eat and restore your body's homeostasis. Drive theory also highlights that once a behavior reduces a drive effectively, it becomes a habit, making it more likely to be repeated in future instances of the same drive.
